1. INTRODUCTION

1.1. Background

The Government of India, through the Ministry of Environment, Forest and Climate Change

(MoEF & CC), is implementing a project on Capacity Building and Industrial Pollution

Management, with financial assistance from the World Bank. Under this project Lake Noor

Muhammed Kunta (NMK) has been chosen for remediation because it plays an important

role for the hydrology of the area.

Lake NMK has a long history of discharge of residential and industrial wastes from the

industrial areas in the catchment of the lake. The historical waste discharges have resulted

in accumulation of pollutants in surface waters, soils and sediments throughout the

catchment area. In an effort to reduce the loading of nutrients and pollutants to the lake, an

STP has been constructed that has been in operation since 2009. The STP treats part of

the wastewater generated in the catchment area. Treated water is released into Lake NMK.

The ultimate goal of the efforts of the Telangana State Pollution Control Board (TSPCB) is

to successfully remediate Lake NMK. To achieve this goal the project should identify and

elaborate on the most effective method to minimise the loading of nutrients and pollutants

to the lake.

1.2. Project goal

To enable design of effective remediation measures Witteveen+Bos has included a

systems analysis in its offer to the client. This systems analysis provides guidance for

optimisation of the project execution. The following questions will be key to this

optimisation:

- What is the maximum nutrient loading that lake NMK can deal with (carrying capacity)

in the current situation?

- What will be the effect of the already proposed measures (dredging and sand spraying)

on the nutrient loading to the lake?

- Can the nutrient loading to the lake be limited to this maximum using water treatment

techniques?

If so, which technique is most suitable and effective?

If not, which water treatment technique can best be applied to limit the nutrient

loading as much as possible?

To answer the first two questions an assessment of the carrying capacity of Lake NMK in

both the existing and future situation will be made. To answer the third question an

assessment of effect of various possible water treatment measures is made. Based on the

system analysis the impact of various measures on the water quality in the lake is predicted

taking into regard the functioning of the water system throughout the year. If remediation is

feasible by upgrading the STP facilities, a maximum allowable discharge standard for the

STP will be given.

2. EXISTING SITUATION

In this chapter general information about the site is described. The information is obtained by a preliminary desk study and site-visits. In appendix I a photo report of the area is shown.

2.1. Land use and local industries

Noor Mohammed Kunta (NMK) is a lake near the city Hyderabad in India. It has a

catchment area of about 190 hectares (see ‎appendix III) and receives wastewater

discharges and storm water runoff from industrial and residential areas. The discharges

from the lake flow to another lake downstream.

The NMK watershed consists of several residential and industrial areas as illustrated in

figure ‎2.1. This map is based on earlier studies (IGEP, 2012) and presents the general

characteristics of the area. Important areas are described in the following paragraphs and

for the drainage study we will focus in more detail on several areas..

Figure ‎2.1. Land use in the catchment area around Lake NMK

Kattedan Industrial Area

The Self Employed Industrial Park (SEIP) Kattedan, or Kattedan Industrial Estate (KIE) was

developed by the APIIC during the 1980s and is the main source area of the pollution [ref.

3]. There is no public water supply in the area and the industries meet their water demand

through individual arrangements. The land use of the KIE is dominated by built-up area

comprising industrial, residential, commercial and institutional activities.

In total approximately 550 industries are present at the KIE. In appendix II a complete

overview of the industrial activities is submitted.


4

At the KIE most of the industries are in small-midscale sector and are indicated as ‘green’

industry. Most of the industries at the KIE release their effluent into nearby ditches, drains

and streams and the solid waste is randomly dumped on open land along roads and lakes.

The industrial effluents contain appreciable amounts of inorganic and organic chemicals as

their by-products.

Sewage treatment plant (STP)

The domestic waste water at the residential areas in the surroundings passes by a pipeline

to the sewage treatment plant located next to the lake NMK. The secondary level treatment

plant has a capacity of 4 MLD, is operated by HMDA. At the moment the STP serves only

RAM residential area and a small part of the Industrial area KIE (total 20 ha) as per figure

2.1 (total area is about 230 hectares). The STP consists of an influent buffer, 2 parallel

aeration tanks, and biological treatment of the sludge, a sludge separator and an effluent

buffer. At present the STP is operated with a capacity of 1-2 MLD. The treated water is

discharged into the lake.

Wastewater pools

A storage tank, as part of the pumping station, for the waste water from the residential

areas is located at the eastern boundary of the lake NMK. It is indicated in figure ‎2.1 as the

pumping station. Next to the collector a highly contaminated flood area (heavy metals,

organics, inorganics, TPH, etc.) is situated (see the wastewater pool location in figures 2.1

and 2.2). This flood area is fed by open drains containing waste water from the KIE but also

from the storage tank itself when the capacity of the collector is exceeded.

Figure ‎2.2. Flooded area, wastewater pool, highly contaminated area next to the

collector and pumping station

2.2. (Geo) hydrological description

The Noor Mohammed Kunta Lake area is gently sloping towards the north with the

industrial area located in the highest elevated areas to the south. The general flow direction

of the catchment is towards the northwest.

Groundwater

The groundwater occurs under phreatic conditions in the shallow weathered zone and

under semi confined to confined conditions in the fractured and sheared zones at deeper

levels. In general the weathered zone thickness is limited to 10-15 m thickness. The

groundwater level, measured at several locations, has an average level of approximately 8-

10 m-bgl. Groundwater level contours show a predominant groundwater direction towards

the Mir Alam Tank (north east, see figure 2.3), but it has to be mentioned that groundwater

levels and groundwater direction are influenced by local pumping conditions.

Lake NMK Noor Mohammed Kunta is a small surface water body located in Kattedan Industrial area of Rajendranagar municipality adjoining Hyderabad city. Geographically, this lake is situated 78°26’ East longitude and 17°18’45’’ North latitude on the southern suburbs of Hyderabad

City. In figure ‎2.3 a view of the lake Noor Mohammed Kunta is given.

Figure ‎2.3. Lake NMK as seen from the sewage treatment plant

The depth of the lake ranges from 0.5 m in the edges to 3.5 m - 4 m in the deepest part.

Based on the hydrographic survey conducted by APERL, the area of the water spread in

1997 has been estimated as 7.95 ha, with a maximum depth 3.9 m with a water elevation

of +98.30 and lowest river bed level at RL +94.40. The total capacity of the lake at RL

+98.30 has been estimated as 0.1626 MCM (5.75 MCFT).

NMK lake catchment

Following a field visit in June 2015 a detailed map of the NMK lake’s catchment area, with

the different types of drainage was made (figure ‎2.4). The area has a large number of small

drains which have not all been included in the image. The largest and most important flows

are shown.

The image illustrates the complexity of the drainage system and the wide range of canal

types.


6

Only a small part of the catchment has a closed sewage system, namely part of the Sri

Ram Nagar residential area and some parts of the Madhuban and APHB Colony. Most

sewage flows into the (lined and unlined) surface drains.

Figure ‎2.4. NMK lake catchment area with its main flow paths and drain types


7

There are three main flow paths in the area, which are described shortly below.

Stream 1

The main and largest drainage route (stream 1) flows from the southeast and through the

northern areas. It passes and collects water from: - Residential area of Madhuban colony and APHB Colony.

- Private industrial estate #1. - Self Employed Industrial Park (SEIP) Kattedan.

Industries in SEIP Kattedan do not have a system in place to treat their trade / industrial

effluent. Consequently, the effluent is mixed with sewage and discharged into stream 1 that

carries sewage, industrial effluent as well as storm water.

Figure ‎2.5. Blocked flow to the pumping station


8

Figure ‎2.6. Breach in the wall of the channel originally leading to the STP

Stream 1 used to be connected to the pumping station but this flow has been blocked (see

figure ‎2.5). Presently, the water flows into a (stagnant) pool of wastewater next to the

pumping station. This pool overflows through a culvert under the road into another pool,

before it flows through a second culvert under the railway line into the NMK Lake. Figure

‎2.7 gives a schematic overview of the flows to the lake. The flowpaths are based on field

observations and measurements (see ‎appendix IV). The two culverts are indicated by

triangles.

Figure ‎2.7. Schematic overview of the flows to the NMK Lake


9

Stream 2

The second large water flow (stream 2), located to the south of the lake, and comes

through sewage lines from the RAM residential area and the private industrial area #2. This

water flows through sewage pipes to the pumping station and is pumped to the sewage

treatment plant (STP). During heavy rainstorms the pumping station cannot cope with the

large water flows and the excess water is directed into the wastewater pool.

The surface flow around the sewerage line itself flows straight into the lake. This water

flows through an open earth drain underneath the railway tracks and over the surface

(joining with steam 3) to the lake.

Stream 3

Stream 3 is actually a collection of surface flows, with waste and storm water from the area

around stream 2, Netaji Negar and the truck workshop area. This water flows directly into

the lake.

3. HYDROLOGICAL MODEL

3.1. General

This chapter describes the local hydrological conditions and patterns in the NMK lake

catchment area during monsoon and pre-monsoon season. The hydrological assessment

in this chapter is performed with two main objectives. Firstly, to determine the peak flows in

the main industrial and domestic drainage canals during the wet and dry season. An

analysis is made of the present capacity of the drainage system in the NMK area, which is

valuable information to determine flood prone areas and identifying gaps in the present

drainage system. In future these results can be used to design a more robust drainage

system. The outcome is used for the GAP analysis in chapter 5. Secondly, the 24 hour

average flow towards the NMK Lake during the monsoon season and the pre-monsoon

season are determined. This information is directly related to the needed capacity of the

STP. This flow is used in following chapters to determine nutrient loading that lake NMK

has to deal with (carrying capacity) in the current situation.

A hydrological model has been set up in Sobek (version 12.002) for the hydrological

analysis of the NMK lake catchment. The following paragraph further describes the set up

of the Sobek model. Then in section 3.3 the peak-flows as calculated by the model are

presented and a short flood risk analysis is made. Section 3.4 assesses the daily average

wastewater flow that is to be expected during the pre-monsoon and monsoon seasons.

3.2. Model set-up

For a more detailed understanding of the present local hydrology, a hydraulic model has

been set up in Sobek (v12.002). Two scenarios have been modelled: the dry pre-monsoon

season and the wet monsoon season. The NMK catchment is a highly complex area with a

large diversity of discharge routes and canals. For this reason only the main drainage

routes have been included in the model which has been designed using existing data,

reports and experience from the field visits. shows the three main flows, that are included:

- Stream 1 is the largest flow, receiving all the wastewater and storm water from the

residential area of Madhuban colony, private industrial estate #1 and KIE.

- Stream 2 is the sewerage stream from RAM residential area and the private industrial

area #2 that is pumped to the STP and then into the lake.

- Stream 3 is a collection of the surface flows from Netaji Negar, the truck workshop area

and a small part of the RAM residential area.

Figure ‎3.1. Schematisation of modelled flows

Model inputs

Rainfall data, field measurements and the capacity of the pumping station are known

variables which have been used as input for the hydrological model. The peak flows during

the pre-monsoon season are modelled using field measurements as an input, while the

peak flows for the monsoon season are modelled using statistical rainfall data of extreme

rain events in the area, with field measurements for validation. The 24 hour average inflow

into the lake is determined by comparing the peak rain events to average rainfall data.

These inputs are described below.

Pre-monsoon season field measurements

Flow measurements were conducted in the field at several locations during the monsoon

and pre- monsoon season of 2015 (day time measurements). Figure 3.2 shows the

average pre-monsoon flows that have been used in the model; a total of 28 l/s into stream

1 and 10 l/s in stream 2.


13

Figure ‎3.2. Average base flows

Monsoon season field measurements

Figure 3.3 is a schematic overview of most important measurement locations for monsoon

season flows. The points indicated with M# are locations at which field measurements were

conducted and these points will be used in the following sections to further describe the

model results and compare them to the data from the field.


14

Figure ‎3.3. Most important flow measurement locations during the monsoon

season

Table 3.1 gives the average daily flow at these points as derived from the field

measurements. High volumes were measured at M6 and M12 which is to be expected

because they are situated on the direct flow path from stream 1 to the lake. Stream 1 is the

largest canal because it receives water from both KIE and the upstream residential area of

Madhuban colony and private industrial estate #1.

Table ‎3.1. Average flows during the monsoon season as derived from the field

measurements

M7 1.1

M9 21.8

M12 240.9

M13 1.9

M15 9,42

M16 423.1

A small adjustment is made to the measurement at M15 that measures the flow from the

STP to the lake. While the pumping station is turned on, the flow to the STP (and

consequently from the STP to the lake) is expected to be around 50 l/s, which is in

correspondence with the measurement of 56.5 l/s. However, this is not the correct volume

when considering the average daily (24 hr) flow volume because the pumping station is not

running full time. The pump is assumed to be running for 6 hours each day so the

measured volume divided by 6 (1/3 day) so it represents the average daily flow.


15

Pump discharge

The pumping station, just east of the lake, has five pumps which were installed to pump

sewage water from stream 1 and stream 2 to the STP. In reality only one of these pumps

functions at a time, with a capacity of approximately 170 m3/ hour.

Pumping Station has a holding capacity of 0.5 MLD. Pumping to STP is done in 3 batches

per day.

Statistical rainfall data of extreme events

For the extreme rainfall events, rainfall depths with a return period of 1 year and 5 years

were used, see table 3.2. The 1 and 2 hour duration of the events is based on the system

time of concentration, which is the expected time it takes for a drop of water to flow from

the top of the system to the bottom. The estimated time of concentration of 1 to 2 hours

was underpinned by the experience of locals.

The amount of rainfall was derived from [ref. 1] and divided equally into timeslots of 15

minutes.

Average rainfall data

Rainfall data from the Hyderabad area from 1980 to 2002 has been used to determine

average rainfall. The average monthly rainfall was derived and using the average number

of ‘rain days’ per month, the average rainfall on a rainy day was calculated. During the

monsoon season it is expected to rain near to 18 mm per day on a rainy day.

Additional input

Some additional input is needed for the hydrological model beside the field measurements

and rainfall data. The most important points are listed below. These are based on field

visits, existing reports and expert judgement.


16

The dimensions of the canals and structures were derived from field measurements and

pictures taken during the field visit:

- Hydrological characteristics of the canals and floodplains were based on experience

from the field.

- Each model run spans a period of 24 hours.

- The modelled canals are filled with the base flow at the start of the simulation, based on

field measurements during pre-monsoon season.

- The beginning of stream 1 is estimated to have an elevation of 4 meters above the

pumping station. The beginning of stream 2 is assumed to be 2 meters above the

pumping station [ref. 2].

- Different canal types have different flow resistance:

Earth lined and surface flow canals have the manning n coefficient of 0.022 s*m-⅓

and 0.035 s*m-⅓ respectively.

Open concrete canals have the manning n coefficient of 0.014 s*m-⅓.

Closed sewage pipes are assumed to have the Colebrook White coefficient of

0.03 m.

- The culvert between the two wastewater ponds has a width of 1.4 m and height of 0.8 m

(see appendix I, picture 14).

- The culvert between the second wastewater pond and the lake has a width of 2.5 m and

height of 0.8 m. This is an assumption. The outflow is over land to the lake (see

appendix I, picture 15).

- The culvert at the lake outflow has a width of 0.3 m and height of 0.3 m (see appendix I

picture 29).

- Inflow points of rainwater runoff are located at strategic points along the streams. The

used catchments, their size and the inflow points can be seen in appendix III.

3.3. Assessment of peak-flow

In this section the peak flows from rainfall runoff, industrial discharges and domestic waste

water flows is given, as proposed in subtask 1.1e of the TECH-4 report. The peak flow is

determined for the pre-monsoon and the monsoon seasons separately.

3.3.1. Pre-monsoon season

During the pre-monsoon season there is assumed to be only dry weather flow (base flow),

which means that the only water in the system is sewage and industrial wastewater. Point

measurements of the flow and water level at different locations were made during the field

visits and used as input for the hydrological model (figure 3.2) flows and water depths

calculated with the Sobek model are illustrated in figure 3.4.


17

Figure ‎3.4. Flow and water depth at base flow (pre-monsoon season)

During field visits, water depths were also measured at several locations in the system. The

locations can be seen in figure 3.3 and the measured water depths are summarised in

table 3.4. The modelled and measured water levels are very similar, indicating that the

modelled canals are most likely a relatively good representation of reality.

Modelled depth 0.43 0.10 0.11 0.20

The water levels in the canals during dry weather are low. Stream 1 has a slope of about

1/300 and has the highest water level downstream, where the flow to the pumping station is

blocked (M6). Stream 2 has ample depth for the base flow, with a constant flow of 8 to

12 l/s being pumped to the pumping station. There is a small flow in stream 3. The

measurements show flows between 0.9 and 2.5 l/s in dry conditions.

.

During base flow periods there is no flooding of the main canals except for the overflow of

stream 1 into the swamp area, due to a blockage of the canal. As a result of this blockage

large volumes of water flow directly to the lake without treatment. This same base flow will

be present during the monsoon season but due to an increase in precipitation the total

flows will be much higher.


18

3.3.2. Monsoon season

The following section gives an overview of the expected flow volumes and velocities in the

main drainage canals during the monsoon season. Sobek was used to assess the peak

flows after big rainfall events. The model outcome is compared to the available point

measurements that were made during field visits. Unlike for the pre-monsoon model,

statistical rainfall data of extreme rain events is used as a model input, so not the point

measurements.

For the extreme rainfall events, 1 and 2 hour events with a return period of 1 year and 5

years were used. As mentioned earlier, the 1 and 2 hour duration of the events is based on

the system time of concentration, which is the expected time it takes for a drop of water to

flow from the top of the system to the bottom. During field visits and the monitoring

campaign we discussed the flooding problem with management of several industrial

companies and STP staff. The estimated time of concentration of 1 to 2 hours was

underpinned by the experience of locals.

Table 3.5 shows the maximum flow at different points in the system during different rainfall

events. The maximum flows are very high and result in flooding throughout the catchment.

These peak flows are interesting to determine the flood volume after a large rain event and

can be used to design a more robust drainage system. The volumes indicated below are

the maximum flows after a large rain event (22 to 40 mm) and will only occur during or

shortly after the downfall.

Table ‎3.5. Maximum modelled flows in 24 hours after event

Maximum flow through points (litres/sec)

M6 M7 M9 M12 M13 M15 M16

Base flow 28 0 10 28 0 10 38

T1 for 1 hour 1355 360 120 1160 930 50 100

T5 for 1 hour 1376 490 124 1240 1255 50 151

T1 for 2 hours 1270 220 115 1235 623 50 137

T5 for 2 hours 1310 330 118 1340 900 50 200

Table 3.5 shows that the flow velocities during a 1 hour storm are higher than during the

first hour of a two hour storm. Thus, the system has to cope with larger volumes of water in

a shorter time span. On the other hand, the longer storms have a higher total rainfall

volume. This has to be taken in consideration when designing the capacity and storage

basin of a new pumping station.

Flow percentages

The modelled flow volumes have been used to give an indication of the percentages of the

total flow volume in different parts of the catchment. This is illustrated in figure 3.5.


19

Figure ‎3.5. Percentages of the total flow volume

The calculations show that the largest volume of storm water flows through stream 1 and

into the first wastewater pool. The volume of water transported to the STP is very minimal

in extreme storm water conditions.

Water levels and flooding during storm events

Large parts of the drainage system floods during storm events. Table 3.6 shows the

modelled water levels at several points in the system (see figure 3.3 for locations).

Table ‎3.6. maximum water depths during storm events

T5 for 2 hours 1.70 1.60 0.4 (full) 1.45 0.31 0.27

The red bold numbers in the table indicate flooding at that point. Point M13 can be seen as

always flooding because it is situated in stream 3 which is a combination of several

overland flow paths (see figure 3.6).


20

Figure ‎3.6. Flow from truck repair shops to NMK lake

The outflow from the lake is not much higher than the base flow. This is due to the storage

capacity of the lake which holds much of the runoff water and discharges it slowly. Also the

water levels are taken after the small (0.3 x 0.3 m) culvert, which only allows for a low flow

velocity.

During storm events the drains fill up very quickly and the excess water floods the areas

around the drains. The flooding is worst along stream 1, where all the canals are rectangles

of approximately 1.0 to 1.2 meters wide and 0.8 to 1 meter deep. To model the flooding on

the streets these canals were not modelled in their actual form (see figure 3.7a), but were

modelled to include surface storage of about 10m3 per meter canal (see figure 3.7b).

Figure ‎3.7. Modelling canals with flood area

(a) Basic (b) With flood area

Even when including this extra storage, the model indicated flooding in downstream

segments of stream 1, lasting for 6 to 12 hours after the start of the rain event. It takes that

amount of time for all the water to flow downstream and overflow into the wastewater

ponds.

Model results vs field measurements

Table 3.7 gives the measured and modelled flow volumes in l/s and the deviation of the

modelled monsoon flows from the measured monsoon flows. The table shows that the

difference between the modelled and measured volumes can be very large. These

deviations are however easily explained.


21

To start with, the measurements presented below are based on several point

measurements conducted over a number of days at certain times. We do not have a

dataset with continuous measurements to work with which makes it difficult to determine

the actual average flows. Furthermore, the T1, 1 hour rain event represents extreme rainfall

that is to be expected once each year. It is unlikely that the measurements were conducted

after an event of that magnitude. Thus the exact difference between the measured and

modelled data is not of interest but the order of magnitude of the flows.

3.4. Assessment of waste water volume quantification

This section describes the present, 24 hour average flow towards the NMK lake during the

monsoon season and the pre-monsoon season, which will be used in following chapters to

determine nutrient loading that lake NMK has to deal with in the current situation.

During the pre-monsoon season there is assumed to be only dry weather flow (base flow),

which means that the only water in the system is sewage and industrial wastewater. The

average 24 hour flow is the same as the flow described in section 3.3.1.

The average daily lake inflow during the monsoon is based on hydrological calculations

using daily rainfall data from 2014 to 2015. For these years daily rainfall data is available.

From the data we concluded monsoon in these years was relatively dry. Therefore we also

assessed the average monsoon conditions, based on monthly data. The calculated

average flows are lower than the T1 event flows because the T1 event represents an

extreme rainfall event.

Table 3.9 shows the calculated average flows during the monsoon.

4. ECOLOGICAL ASSESSMENT

4.1. Approach to ecological assessment

To create an understanding of the water quality issues at hand in Lake NMK we make an

ecological assessment in which a systems approach is used. This analysis focuses on

identification of the key processes that define the water quality in Lake NMK. To identify

these processes we look at both the current condition of a lake (its appearance), and the

preconditions (the factors and processes that cause this appearance). The reason for

choosing this approach is that the current condition of a lake can be the result of different

developments in the past. In other words, the current condition only tells half the story. To

be able to identify effective measures the factors and processes that cause water quality

problems have to be well understood. Selection of measures based on the current

condition alone may result in choice of suboptimal measures.

For the assessment of the preconditions we make use of the conceptual framework of the

Ecological Key Factors (see textbox). This conceptual framework helps us to structure the

analysis. In the framework the water quality in the lake is considered in the light of 9

identified preconditions. For every precondition a separate assessment is made. In this

assessment a check is done whether the lake does comply with the defined precondition in

the existing situation.

Creating understanding using Ecological key factors

To facilitate the identification of preconditions for improvement of ecological water quality and enable application of

measures in an effective sequence the so-called ‘Ecological Key Factors’ have been developed by Witteveen+Bos

Consulting Engineers in cooperation with knowledge institutes in the Netherlands. The ecological key factors provide

a framework for systems analysis. The ecological key factors have been developed to enable identification of the

most effective restoration measures for lake specific conditions. A key aspect of this approach is that a certain

hierarchy is present in the preconditions for ecological recovery. This means that these is also a specific following

order in which restoration measures are best applied to achieve the maximum effect of measures and make

restoration measures as cost effective as possible. The key processes in water system functioning have been

caught in 9 ecological key factors. The focus in the key factors is on the development of submerged aquatic

vegetation because vegetation plays a crucial role in the ecological functioning of water systems.

Ecological Key Factor Symbol

1 Toxicity

Contaminants or extreme conditions can result in both acute and chronic toxic effects on

plants and animals. Biological productivity can be severely inhibited by toxicants.

2: Organic loading/Short term oxygen dynamics

Oxygen depletion as a result of organic loading can inhibit biological productivity.

3: Productivity of the water

For the development of submerged water plants, the most important precondition is to

have sufficient light reaching the sediments below the water. Excessive external nutrient

loading results in production of (potentially toxic) algae.

4: Light climate

The development of an healthy vegetation of submerged and emergent aquatic plants,

sufficient light should reach the lake bottom to enable and stimulate germination of seeds

and plant growth. Both suspended matter and coloration of the water block the


24

penetration of light in the water and limit the potentials for vegetation development.

5: Sediment productivity

Sediments absorb part of the external loading. Once the external loading is reduced

nutrient fluxes from the enriched sediments can have an adverse effect on the

development of the ecological water quality by stimulating growth of harmful algae and

floating plants.

6: Habitat suitability

The development of shoreline plants depends on the presence of suitable habitats, e.g.

sufficient water level fluctuation, sufficient shallow waters, and favourable sediment

properties (consistency).

7: Dispersal

Habitats must be reachable for species to enable population development. Sufficient

connectivity is required to enable dispersion of species.

8: Disturbance

Disturbance of habitat can severely impact the success of populations. Disturbances can

be both natural (grazing, perturbation) and anthropogenic (dumping, digging).

9: Context/Experience of natural beauty

Good water quality is very subjective. Both local conditions and local customs define what

good water quality looks like. Social and religious functions may result in different

ambitions for water quality than the ecological perspective. Therefore, the experience of

the water is a factor that has to be taken into account in addition to the more objective

factors above.

To improve the ecological water quality of NMK the nutrient loading to the lake should be in

balance with the critical nutrient loads of the water system (see table 3.3). The nutrient

balance is assessed as part of the assessment for ecological key factor 3, productivity of

the water. The critical nutrient loads of lakes depend on the lake specific morphological and

hydrological features, such as water depth, retention time, sediment type, wind fetch etc.

The ecological model PCLake model calculates the critical nutrient loads using these lake

specific parameters. The model has been developed for fresh water lakes, but can also be

applied to salt water lakes. When the model is applied to salt water the uncertainties

around the calculated values are higher than for fresh water lakes.

PCLake predicts the impact of phosphate and nitrogen loads on water quality. With this

model the development of water quality and the effects of various measures on existing

and new water systems can be examined. PCLake is currently applied in a variety of water

systems within and outside Europe.

Table ‎4.1. Influence of nutrient loading on ecological functioning

An important factor in the definition of the appearance of a lake is the nutrient load. The figure below illustrates the

theory of alternative stable states in the context of nutrient loading:

- When nutrient loads are low (situation I), the water can be expected to be clear based on biological productivity.

The productivity will mainly consist of plants and animals. These waters generally have a very good water

quality and can perform critical functions like swimming water and other forms of recreation in a sustainable

way.

- As nutrient loading increases (situation II), the water will remain in a clear vegetated state for a long time. When

the nutrient loading exceeds a critical threshold (illustrated by the line between II and III), the water changes

from a stable clear state to a stable turbid state (situation III).


25

- In the stable turbid state the high nutrient concentrations are mainly used by algae for biomass production. As a

result the water transparency is low and light conditions are limiting for production of submerged vegetation.

Several species of algae that can be expected in situation III can produce dangerous toxins. Waters in situation

III can be used for e.g. boating, but cannot support critical functions like swimming

- To initiate a transition from a stable turbid (III) to a stable clear state (I), the nutrient loading has to be

decreased. Only after reduction of the nutrient load until below a critical threshold (illustrated by the line

between I and II), can a stable clear state (situation I) be expected to occur.

- The critical thresholds for transition from clear to turbid (between II and III) and transition from turbid to clear

(between I and II) are defined by the characteristics of the lake and are there for lake specific. Depending on

the lake characteristics both thresholds can differ. In these situations restoration of the clear state requires that

the actual nutrient loading is reduced further than the nutrient loading at which the transition from a clear to a

turbid state has occurred (hysteresis effect). If the actual nutrient load to a lake is between both critical

thresholds, the lake can both occur in clear and turbid states, but the state will be unstable.

N/P-ratio

An important factor determining the level of the critical load is the N/P-ratio. The proportion

of N-load compared to the P-load determines the availability of these nutrients for primary

production by algae and plants. The optimal ratio for growth of algae (and plants) is about

7(g/g, 16:1 mol/mol), the well-known Redfield-ratio. Liebig’s law of the minimum states that

primary production is controlled by the scarcest resource available (limiting factor).

Therefore the critical nutrient load is also dependant on the N/P-ratio of the nutrients. The

critical loads are calculated for different N/P-ratios: N/P =1, 7 and 34. These three values

represent possible scenarios:

N/P = 1: Nitrogen is the limiting factor for growth

N/P = 7: Both nutrients are around the optimal ratio for growth, both nutrients are alternating as limiting factor

N/P = 34: Phosphor is the limiting factor for growth

Nitrogen as a limiting factor contains a risk for enhanced growth of nitrogen fixating blue-

green algae. In order to avoid scums of blue-green algae, nitrogen should not be the

limiting factor for growth. This can be achieved by limiting the input of phosphorous.

Phosphorous is leading as a limiting factor for growth.

4.2. Assessment of existing situation

Based on the field visits a preliminary assessment of the ecological condition of lake NMK

has been made. In table 4.2 the current condition is described with the Ecological Key

Factors.

Table ‎4.2. Assessment of the current situation in lake NMK with the Ecological Key

Factors

Ecological Key Factor Description Symbol

1. Toxicity There are no signs that the toxicity is limiting the productivity of

vegetation since vegetation is abundant in the marsh areas of the

lake. Yet, it is clear that the sediments contain significant amounts

of toxic chemicals. Furthermore frequently peak discharges occur

in which elevated concentrations of chemicals are observed.

2. Organic loading/

Oxygen dynamics

The oxygen dynamics in NMK are disrupted as a result of the

discharge of very large volumes of organic matter to the lake. The

high oxygen consumption in the water is clearly visible in the

blackness of the discharged waters and the lake and dissolved

oxygen levels at the outlet of the lake of less than 2 mg/l on

average.

3. External loading The waters that are discharged into lake NMK are very rich in

nutrients and make the lake hypertrophic. The excessive nutrient

input disrupts the ecological functioning of the lake. The nutrient

dynamics are explored in the next paragraph.

4. Light climate The excessive input of organic matter and nutrients results in a

very poor light climate in the lake. Transparency is generally very

limited. It is therefore expected that light climate is a limiting factor

in the growth potential of submerged vegetation.

5. Sediment productivity The lake bed of NMK is characterised by thick layers of sludge that

is rich in both organic matter and nutrients. The sludge will

contribute significantly to the nutrient availability in the water.

During periods when the nutrient concentrations in the water are

high, the sludge may act as a sink for nutrients. However, when

nutrient concentrations in the water layer decrease, the sludge will

start acting as a source of nutrient by releasing nutrients to the

water layer. This process will be accelerated under anoxic

conditions.

6. Habitat suitability Based on the current assessment the habitat suitability does not

appear to be limited for ecological recovery.

7. Dispersal Upstream migration of fauna to lake NMK is limited by the outlet

structure of the lake. The current vegetation in and around the lake

shows that dispersal is not a limiting factor for vegetation

development.

8. Disturbances Dumping of solid waste and large volumes of fine organic particles

is causing some disturbance in both the drainage and the ecology

of the lake.


27

Ecological Key Factor Description Symbol

9. Context The lake is intended to act as a tank for the collection of water for

irrigation. The water quality is however too bad to use the water for

this purpose. The lake suffers from extensive dumping of solid and

liquid wastes.

The key issues for the ecological water quality in Noor Muhammed Kunta are organic

loading, external loading and sediment productivity. A more detailed assessment of the

nutrient dynamics in the lake has been made to gain insight in suitable measures to

address the issues with these key issues. The results have been presented in the following

paragraph.

4.3. Nutrient balances

4.3.1. Existing situation (reference)

For the ecological water quality the water flows that are received by the lake itself are of

importance. As a result of the blockage of the stream 1 (from Kattedan SEIP) in front of the

pumping station and the breach in the channel wall a short circuit around the STP is

created. Due to the short circuit the waste waters from stream 1 do not pass through the

STP, but are discharged to lake NMK untreated. The waste waters coming from stream 2

(coming from Sri Ran Nagar) pass through the pumping station and the STP before being

discharged into the lake.

Nutrient concentrations

To gain insight in the existing water quality the water flows in the Kattedan Industrial Estate,

the STP, and lake NMK have been sampled both in the pre monsoon (9 to 12th of June

2015) and the monsoon (20th August to 17

th September 2015). Tables 4.3 and 4.4 show the

nutrient concentrations for a select number of locations. In appendix VI a complete

overview of the analysis results is given.

Critical nutrient loads

The critical thresholds for nutrient loading to the water system have been calculated with

the eutrophication model PCLake. The input in table 4.5 has been used to model the

existing situation. Surface areas have been calculated based on Google Earth satellite

images. The average depth is derived from the remediation plan for NMK (Witteveen+Bos,


28

2013). For this calculation the total area of the open water of lake NMK and all marshes

has been taken into account.

Figure ‎4.1. Relation between N:P ratio and the critical P loads for the dry season

The analysis results of the water samples that were collected from the discharges to the

lake show that the average N:P ratio in the discharged waters is 2. For this reason this N:P

ratio has been used in the calculation of critical loads in this chapter. Figure 4.1 illustrates

that the critical load does not have a linear relation with N:P ratio, but increases with

decreasing N:P ratio. The N:P ratio defines which nutrient is limiting for biological

productivity. With low N:P ratios N is most limiting for biological production, resulting in a

higher carrying capacity for P. As a result the critical P load (the carrying capacity)

increases as the N:P ratio decreases.

In the model calculation an average water temperature of 26˚C has been used for

Hyderabad. At such high temperatures the critical load for transition from clear to turbid

coincides with the critical load for transition from turbid to clear. For this reason only a

single critical load is described in the results. In table 4.6 the critical load for the existing

situation in NMK is given for the dry season. In addition the critical load is given for the

monsoon season. This calculation is based on the average flow that can be expected

during rainy days in the monsoon season.

Current nutrient loading

For the calculation of the current nutrient loading the predicted flows from the hydrological

assessment are used. The total N and total P values from table 4.4 are multiplied with the

calculated flows to acquire nutrient loads.

Before the monsoon a total flow of 38 l/s (3.5 MLD) was found, of which 10 l/s was passing

through the STP and 28 l/s was discharged directly into the lake (figure 4.2). During the

monsoon the total discharge increases drastically and accounts on average 195 l/s on rainy

days. The capacity of pumping chamber and pumps are limiting the total flow to the STP.

As a result the direct discharge to the lake accounts for about 95% of the total discharge

(figure 4.3).

In tables 4.7 and 4.8 the actual nutrient loading to the lake is calculated for the dry season

and the monsoon season respectively.

Conclusion for reference situation

Total P load is estimated at 1,146 (dry season) to 4,387 (monsoon season) mg P/m2/day.

The critical P load has been calculated to be 9 and 40 mg P/m2/day respectively for the dry

season and the monsoon season. This shows that the actual loading exceeds the critical

loads by a factor 100 to 125. This makes the lake hypertrophic. A very drastic reduction in

nutrient loading is required to improve the ecological water quality.

In the existing situation the bulk of the nutrient loading results from the direct discharge to

the lake from the Kattedan Industrial Estate. The effluent from the STP has only a minor

contribution to the total nutrient loading. Its contribution is negligible during the rainy days in

the monsoon period. Note, however, that even the nutrient loading to the lake by the

effluent from the STP exceeds the critical load of the lake in the existing situation up to a

factor 7.

Without the nutrient removal by the STP the nutrient loading to the lake in the dry season

would amount to 1,455 mg P/m2/day. This shows that STP reduces the nutrient load to the

lake considerably. However, the STP has no significant effect on the water quality of lake

NMK because the lake remains hypertrophic, both with and without the nutrient removal by

the STP. As a result algal blooms will still occur.

4.3.2. Scenario 1: Restoration of STP infrastructure

An obvious remediation measure would be to reconnect the discharge channel from

Kattedan to the pumping station and the STP by removal of the blockage in the channel

and closure of the existing breaches in the channel wall. The effect would be that, during

the dry season, the full discharge from the catchment of lake NMK passes through the STP

before it is discharged to the lake. During the monsoon season discharges exceed the

capacity of the pumping station, resulting in direct discharges to the lake. Execution of this

scenario would require optimisations and/or adjustments to the STP. For the calculation the

assumption has been made that the STP performance in scenario 1 is identical to the

existing reference situation in which 10 l/s pass through the STP.


The input in table 4.9 has been used to model scenario 1. When all discharges pass

through the pumping station and the STP, only the marshes that surround lake NMK

influence the ecological functioning.


31

The marshes between Kattedan and the railway line do not affect the ecological processes

within the lake and are therefore not taken into account for the dry season in this scenario.

As a result the model uses smaller total surface and marsh areas. During the monsoon

season the marshes between Kattedan and the railway line receive direct discharge and

therefore have to be taking into account in the calculation. Figure 4.4 illustrates the relation

between marsh area and critical loads. The critical loads decrease with decreasing marsh

cover.

Figure ‎4.4. Relation between marsh cover and critical loads for NMK

In table 4.10 the critical load for scenario 1 is given for the dry season. The scenario in

which the total volume of peak flows pass through the STP is not feasible since it would

require a very large STP. The critical load for this scenario can therefore not be given for

the monsoon. In practice the volume that passes through the STP in the monsoon season

will be of the same order of magnitude as in the dry season (i.e. 38 l/s). If we assume that

the rest of the monsoon flow is bypassing the STP and discharged directly into lake NMK,

the critical load for the monsoon season in scenario 1 can be expected to be of similar

magnitude as the critical load in the reference situation, i.e. around 40 mg P/m2/day.

For the calculation of the nutrient loading in scenario 1 the assumption is made that all

remaining volume of 157 l/s would be discharged directly to the lake during the monsoon

season. The calculated nutrient loads are presented in tables 4.11 and 4.12.

Conclusion for scenario 1: Restoration of STP infrastructure

The P load on lake NMK in scenario 1 (restoration of STP infrastructure) is calculated to be

330 mg P/m2/day in the dry season. The critical load is 8 mg/m

2/day. The P load is thus 40

times higher than the critical load. This means that scenario 1 still results in a eutrophic

state of NMK in the dry season.

The STP might be able to process some extra flows respective to the dry season

discharge, however the STP will not be able all discharges. The nutrient loading due to

direct discharge is therefore likely to be of similar magnitude as the nutrient loading due to

direct discharge in the existing reference situation, i.e. 15,000 mg P/m2/day. This still

results in a hypertrophic situation and high biological productivity which should be expected

to express itself in algal blooms.

4.3.3. Scenario 2: Proposed remediation without restoration of STP infrastructure

For the remediation of lake NMK a number of restoration measures has been proposed.

The most important measures are:

- Dredging of polluted sludge and sediments.

- Storage of polluted sludge in containment cells.

- Storage of polluted sludge in geotextile tubes and use of the geotextile tubes to create

a bund around the lake.

- Backfilling with sand to provide a capping for polluted sediments.

- Installation of a weir to formalise the outlet of the lake and enable regulation of the

water level and outgoing flows.

The proposed remediation measures address the sediment toxicity (Ecological Key Factor

1) and sediment productivity (factor 5). These measures do not directly affect the

discharges to lake NMK, but these measures do have an indirect effect on the Ecological

Key Factors organic loading (factor 2) and external loading (factor 3) by their influence on

the height of the critical nutrient loads.


The proposed remediation measures reduce the lake surface area, marsh cover, and fetch

by the construction of containment cells and bunds within the existing profile. The average

depth of the lake is furthermore increased due to the dredging, despite the partial backfilling

with sand. As a result of these changes different critical loads apply to the situation after

remediation. In table 4.13 the input parameters for scenario 2 are given.

In table 4.14 the critical loads are given for the existing situation both for the dry season

and for rainy days during the monsoon. In addition a critical load has been calculated for

the scenario that the catchment area of lake NMK is increased in future, resulting in an

increase in the total discharge to the lake to 4.0 MLD in the dry season. Since it is unknown

how the catchment finally will be extended and in which extra discharge volumes this

results, no reliable predictions can be made for the water quality and critical loads in the

monsoon season in the future situation.

Future nutrient loading

The nutrient loading to the lake in the situation after remediation is identical to the existing

reference situation. Before the monsoon a total flow of 38 l/s (3.5 MLD) is discharged, of

which 10 l/s passes through the STP and 28 l/s was discharged directly into the lake

(figure 4.7). During the monsoon the average daily discharge is 195 l/s, of which 10 l/s

passes through the STP and 185 l/s is discharged directly to the lake (figure 4.8).

Conclusion for scenario 2: Proposed remediation without restoration of STP

infrastructure

The nutrient input in scenario 2 is identical to the nutrient input in the existing reference

situation, but the actual nutrient loading is higher in scenario 2 because the surface area of

the lake is decreased by the construction of buds and containment cells. As a result of the

impact of the remediation measures on water depth, marsh cover and fetch the critical

loads are lower in scenario 2 than in the existing reference situation. Thus increasing the

difference between the critical loads and the actual loading. Because of the large

uncertainties in the model predictions the differences between the nutrient balance

between the existing situation and scenario 2 are negligible. This means that the high

nutrient load should still be expected to express itself in high biological productivity (a.o.

algal blooms).

4.3.4. Scenario 3: Proposed remediation with restoration of STP infrastructure

In this scenario the same proposed measures are taken as in scenario 2, but in addition the

discharge channel from the Kattedan IE to the pumping station is restored. As a result all

discharged flows are guided via the pumping station to the STP as far as the pump

capacity allows.


In table 4.17 the input parameters for scenario 3 are given. The total lake surface area that

affects the ecological functioning and the marsh cover are lower than in the other scenarios

because some area is covered by the geotextile bunds and the containment cell in NMK. In

the dry season the areas are further reduced because the marshes between the Kattedan

area and the railway line are bypassed by the pumping station and the STP. This results in

a critical load of 7.5 mg P/m2/day for the dry season (table 4.18). In the monsoon the

discharge will exceed the pumping and STP capacity, which will result in direct discharge of

the bulk volume of flow to the lake. As a result the STP is still bypassed by the main volume

of the flow and therefore similar critical loads as in scenario 2 can be expected to apply.

of which 38 l/s passes through the STP and 157 l/s is bypassing the STP and flowing

directly to the lake (figure 4.10). This results in the nutrient loads in tables 4.19 and 4.20.

Conclusion for scenario 3: Proposed remediation with restoration of STP

infrastructure

In scenario 3 to measures taken in the scenarios 1 and 2 are combined. This results in a

decrease in nutrient loading to the lake in the dry season in comparison to the existing

situation, but also in increase in nutrient load during the monsoon season. The latter is

caused by a decrease in surface area within the lake as a result of which the same nutrient

input has to be distributed over a smaller area. This results in a higher nutrient loading

(expressed as mg P per square meter per day).

The nutrient balance for scenario 3 shows that the nutrient loading during the dry season is

50 times higher than the calculated critical load. For the average situation during the

monsoon season the actual loading is 125 times higher than the critical load. This means

that the high nutrient load should still be expected to express itself in high biological

productivity (a.o. algal blooms).

4.3.5. Scenario 4: Upgrade of STP with proposed remediation

In this scenario the same proposed measures are taken as in scenario 3, but in addition the

STP is upgraded. The STP capacity will be upgraded from 3.5 to 8 MLD. The existing STP

has been designed to treat the current discharge volume. The upgrade of the STP does

therefore not change the nutrient balance in the dry season. The increase in capacity does

however mean that a larger percentage of peak discharges can be treated by the STP.


In table 4.21 the input parameters for scenario 4 are given. Table 4.22 presents the critical

loads for scenario 4. Input and the critical loads are identical to the situation in scenario 3.

The nutrient loading to the lake in the situation after remediation is identical to the situation

in scenario 1. Before the monsoon a total flow of 38 l/s (3.5 MLD) is discharged which all

passes via the STP (figure 4.11). During the monsoon the average daily discharge is 195

l/s, of which 56 l/s passes through the STP and 139 l/s is bypassing the STP and flowing

directly to the lake (figure 4.12). The nutrient loads are shown in tables 4.23 and 4.24.

The capacity of the STP after upgrading will be 8 MLD or 95 l/s, yet the average volume

that passes through the STP during the monsoon season is only 56 l/s. The reason is that

during the monsoon season it is only raining on about 10 days per month. On these rainy

days the full capacity of the STP (95 l/s) will be used. On the dry days, however, the

discharge to the STP will only be 38 l/s, the same as during the pre monsoon. This reduces

the average daily flow through the STP in the monsoon season to 56 l/s.

Conclusion for scenario 4: Upgrade of STP with proposed remediation

The actual nutrient loading and critical loads for the dry season are identical to scenario 3.

The upgrade of the STP does however result in a larger percentage of the discharge during

the monsoon season being treated. This results in a slight decrease in nutrient input when

it is assumed that the nutrient concentrations in the STP effluent remain the same as in the

existing situation. If the performance of the STP increases due to the upgrade, a further

reduction in nutrient loading may be achieved. Nonetheless the nutrient input will remain

many times higher than the critical nutrient loads, resulting in a hypertrophic situation with

high biological productivity.

4.4. Conclusions on the nutrient balances

In table 4.25 an overview of all calculated critical loads and actual loads is given for the

various remediation scenarios for lake NMK for both the dry season and the monsoon

season.

In the overview the effect of the various measures on the nutrient balance is clearly visible:

- In the existing situation lake NMK receives a very high nutrient load in both the dry and

the monsoon seasons.

- Redirection of the raw sewage from the KIE to the STP (scenario 1) results in a

considerable reduction of nutrient loading in the dry season, but only a 10% reduction

during the monsoon season.

- In contrast the construction of bunds and containment cells for sludge storage (scenario

2) results in an increase in actual load because these measures reduce the surface

area of the lake over which the nutrient input is distributed. The reduction in surface

area and marsh land also result in a slight decrease of the critical loads since some of

the buffering capacity of the lake is lost.

- Scenario 3 shows that combination of the previous two scenarios results in a

considerable reduction in nutrient load in comparison to the existing situation in the dry

season, but this is less pronounced than in scenario 1. This is the result of the loss of

surface area in the lake. The table shows that the actual load during the monsoon is

higher than in scenario 1, but 20% lower than in scenario 2.

- The difference between scenarios 3 and 4 is in the percentage of the total discharge

that passes through the STP in the monsoon season. Due to the upgrade of the STP

the facility is able to treat a larger percentage of the discharge in scenario 4. This

results in a slight decrease in carrying capacity.


42

The effect of the measures on the critical load is negligible since the actual loads to lake

NMK exceed the critical P loads by far. In none of the scenarios does the actual loading

approach the critical load. In all situations the existing eutrophicated state will remain and

ecological restoration will not take place.

The table shows that the critical P loads decrease considerably by restoration of the

channel leading from the KIE to the STP pumping station (scenarios 1 and 3). Despite this

decrease the difference between critical and actual loads is smallest for these scenarios

because the P concentrations in the STP effluent are low in comparison to the P

concentrations in the directly discharges waters. Yet, the actual loads are still 50 times

higher than the critical loads when the current STP performance is assumed. An increase

in the STP performance would result in a decrease in P concentrations in the STP effluent

and will therefore bring the actual load closer to the critical load. The STP performance

would however have to be very drastically improved to bring the actual load within reach of

the critical loads for the dry season.

The calculated nutrient loads to lake are based on the nutrient concentrations that were

found during sampling of the existing situation in the pre monsoon and the monsoon

seasons. This means that also for scenario 4, in which the STP will be upgraded, the

calculations assume that the nutrient concentrations in the effluent remain unchanged. To

achieve a good ecological water quality, the total nutrient load to the lake should be below

the critical load. For the dry season this means that the nutrient load should be below 8 mg

P/m2/day. In scenario 4 the entire base flow of 38 l/s passes through the STP. With this

flow the P concentration in the STP effluent should be below 0.15 mg P/l (currently 7.66 mg

P/l) to meet the critical nutrient load in the dry season. In the monsoon season the bulk of

the nutrient load to the lake results from direct untreated discharges. This nutrient load due

to direct discharges alone already exceeds the critical nutrient load of the lake.

Effect of peak discharges

For the ecological functioning of lake NMK the situation during the monsoon is a dominant

factor. Table 4.23 shows that the average actual load during the monsoon is extremely high

amounting to 4,000 to 6,000 mg P/m2/day. For all scenarios this is 100 to 150 times higher

than the critical loads. In this calculation both the dry and the rainy days within the

monsoon are taken into account. During the rainy days the nutrient loading to the lake will

be even higher.

It is important to be aware that temporary increase in nutrient load can have an impact on

the nutrient balance for a much longer period. The water volume of a peak discharge

(whether or not connected to rainfall) will pass through the lake within a relatively short

timeframe. It is likely that a considerable part of the nutrient loading will be transported with

the water and pass the lake within a short timeframe as well. It has to be anticipated

however that part of the nutrient load remains within the lake due to bonding to organic

matter and sediments. This may occur to a larger extent to clean sediments after

remediation. Even if a small percentage of the nutrient load of a peak event stays behind in

the lake, this is already likely to result in an nutrient loading that exceeds the critical loads.

It is however difficult to assess this effect since critical loads can only be calculated for

longer time scales and not for peak events. A similar time lag will occur between the

seasons with the impact of higher nutrient loading during the monsoon season influencing

the water balance of the following dry season.

High nutrient load to lake NMK due to direct discharges can occur due to rainfall, but can

also occur as a result of illegal discharges. The results of such an illegal discharge were

witnessed during the field work in the dry season.


43

discharge upstream of the company premises

Figure ‎4.14. An increase in the water level of an isolated section due to the same

flood event illustrates the volume of the discharge

Remediation measures to improve the water quality

The nutrient loading that is connected to peak discharges is dominant in the total nutrient

loading to lake NMK. Even if only a limited number of peak events occur throughout the

year, this will already cause excessive nutrient input and keep the lake in the eutrophicated

state. As a result it is not possible to reduce the nutrient input to the lake significantly by

upgrading the STP alone. Even if the performance of the STP would be upgraded such that

the P concentration in the effluent is reduced to zero, the total nutrient load to the lake

during the year would still exceed the critical nutrient loads due to the peak flows connected

to rain events and illegal discharges.

After application of the proposed dredging and capping the input of organic material and

nutrients remain unaltered.


44

The key issues that need to be addressed to achieve improvement of the water quality in

lake NMK will still be the organic loading and external nutrient input. These Ecological Key

Factors will need to be addressed first in order to enable the dredging and capping to have

their full effect. Dredging and capping before action is taken on the external nutrient input

and organic loading will not result in improvement of the ecological water quality. As long

as the external nutrient loading has not been addressed, the risk is that the newly applied

cap of clean sand will first act as a sink for nutrients from the overlaying eutrophicated

waters, and will later act as a source of nutrients (internal loading) once the nutrient level in

the overlaying waters is reduced in a next stage of remediation. Application of dredging and

capping prior to strong reduction of the external nutrient input is not cost-effective. It is

therefore recommended to apply measures in the following order of the hierarchy of the

Ecological Key Factors and address the organic loading and external nutrient loading first.

Figure ‎4.15. Organic loading and external nutrient loading remain the key issues

for the water quality of lake NMK

To create a significant improvement in the water quality of lake NMK the nutrient input to

the lake during peak discharges should be decreased considerably. This should be

achieved by active targeting of sources of nutrients in the catchment area and prevention of

the initial nutrient input to the water system of the Kattedan Industrial Estate.

As a fallback option measures could be taken to guide peak flows around lake NMK by

construction of a special bypass channel. In this case the water quality in the lake could be

controlled by passing all discharges through the STP and upgrading the existing STP. This

does however not provide a solution to the problem, but merely results in shifting the

problems to the water systems downstream of lake NMK.

4.5. Ecological norm versus water quality standards

In the preceding paragraphs the water quality of the flows discharged to lake NMK has

been assessed from the ecological perspective. In the assessment from ecological

perspective the loading of nutrients to the lake is considered. To determine the load the

nutrient concentrations in the water are multiplied by the water volume. This results in

quantification of the total amount of nutrients received by lake NMK.

In the more traditional approach only the concentrations in the discharged waters are

considered. In Telangana State the general standards for discharge of effluents apply.

These standards define the maximum allowable concentration for a selected number of

parameters. The general standards for discharge to surface waters include a maximum

allowable concentration for dissolved phosphates of 5 mg P/l.


45

The general standards for discharge to irrigation waters does not include a maximum

allowable concentration for phosphates.

In tables 4.26 and 4.27 the concentrations of phosphates found during the sampling in and

around lake NMK are compared to the general standards for the dry season and the

monsoon respectively. It has been agreed that the general standard for discharge to

surface waters applies to the discharges to the lake, i.e. the direct discharge and the

effluent of the STP. For the outlet of the lake the irrigation standards apply because of the

prospected use of the waters for irrigation purposes by the agricultural university of

Hyderabad.

Tables 4.26 and 4.27 show that phosphate concentrations in the waters that were directly

discharged to lake NMK exceeded the valid general standards on all days by a great

length. On all days the measured concentrations were 3 to 12 times higher than the

maximum allowable concentrations. The phosphate concentrations in the STP effluent

exceeded the norms on 5 out of 8 days. The measured concentrations on these days

exceeded the maximum allowable concentrations up to twice.

Conclusion on discharge standards

In the situation of lake NMK the classic normative approach allows much larger discharges

of phosphates than the nutrient load-based approach. Yet, the comparison of the actual

concentrations with the general standards show that the discharges still do not comply with

the set standards in most cases.

This means that even based on the normative approach a significant reduction in nutrient

concentrations in the discharged waters is required, both for the discharges from the STP

and the direct discharges to the lake. It is important to understand that the set general

standards are not connected to the ecological functioning and thus do not provide any

guarantee for a good water quality.


46

As pointed out in paragraph 4.4, assessment of the discharges based on nutrient loading

shows that reduction of the nutrient concentrations in the effluent of the STP alone is

insufficient to improve the water quality of lake NMK sufficiently. The nutrient

concentrations in both the effluent of the STP and the direct discharges to the lake (also

during peak events) need to be reduced beyond the set Indian standard to enable

improvement of the ecological water quality.


47

5. GAP ANALYSIS

The previous chapters have clearly shown that the present drainage system is of

insufficient capacity to prevent flooding and maintain a good water quality. The rain events

in the area can be extreme with large volumes of water in a short time, putting a lot of

pressure on the system. In this chapter the findings from the previous chapters are used to

describe weak points in the system and provide recommendations for strengthening it.

5.1. Weaknesses

Discharge volumes and quality

The key issue for the water quality in lake NMK is that the lake is receiving an overload of

nutrients. This excessive nutrient load is the result of high nutrient concentrations in both

the direct discharges to the lake and the effluent of the STP as well as the high discharge

volumes.

Only a small percentage of waste waters is passing through the STP. Most waters are

discharged directly into the lake as a result of blockage in the connection to the STP

pumping station and breaches in the channel wall. During peak discharges the percentage

of the total discharge that passes through the STP becomes marginal. As a result the

nutrient removal has no significance for the total nutrient loading to the lake.

STP performance

At present the STP effluent does not meet the set standards for discharge to surface

waters. Furthermore the nutrient loading from the STP effluent is exceeding the critical

loads for lake NMK in the existing situation. This is the result of the relatively low critical

loads due to the large volume of the direct discharges to the lake.

Canal capacities

The hydrological model has shown that the system is capable of carrying base flows to the

STP without causing overflows or flooding. During storm events however, the drains fill up

very quickly and the excess water floods the areas around the drains. The flooding is worst

along stream 1 because the highest flow volume flows through this stream (around 80%).

During a heavy rainstorm stream 1 fills up quickly, resulting in much of the runoff water

ponding on the streets or running off over land. Especially downstream, near the pumping

station, the canals cannot cope with the flow of water and they flood for periods of 6 to 12

hours, after the start of a storm event. Large volumes flow over land to the first wastewater

pond. Presently all this water, which is contaminated with sewerage and industrial waste,

bypasses the pumping station and flows to the lake.


48

Figure 5.1. Main and secondary channels through Kattedan

Both stream 1 and stream 2 cannot cope with heavy rainstorms. For stream 2, which is a

closed pipe with an outlet to the pumping station and an overflow to the wastewater ponds,

this means that sewerage mixed with rainfall runoff water flows into the lake without

treatment.

The model has dealt with the main flow paths and shown that these are under

dimensioned. The actual drainage system is much more complex. There are many small

upstream drains throughout the industrial and residential areas. See figure 5.1 for all the

drains that were documented after the field visit in spring 2015. There are most likely many

more small streams. Many of these will also flood when the main canals are full.

Pumping station

The pumping station, just east of the lake, has five pumps which were installed to pump

sewage water from stream 1 and stream 2 to the STP. In reality only one of these pumps

functions at a time, with a capacity of approximately 170 m3/ hour. Pumping Station has a

holding capacity of 0.5 million litres per day (MLD). Pumping to STP is done in 3 batches

per day so a total volume of 1.5 MLD. This is in sharp contrast to the 34 million litres rainfall

runoff expected form a T1, 1 hour storm.

Sewage treatment plant

The current use of the STP is 1-2 MLD. This use needs to increase if the drainage system

is expanded and pumping capacity increased. Treating all rainfall runoff water is not

realistic so a balance between quality and quantity problems will have to be found.


49

5.2. Recommendations

Focus on reduction of discharges

The nutrient loading to lake NMK exceeds the carrying capacity of the lake many times,

even during base flow conditions. Upgradation of the STP to treat all discharges under

base flow conditions is technically possible, but does not have any added value if peak

discharges keep occurring. These peak discharges are dominant in the nutrient loading to

the lake. Two types of peak discharges occur, both types of peak discharges need to be

addressed to enable improvement of the water quality in lake NMK.

One type of peak discharges is the result of discharges by the industries in the catchment

of lake NMK. This concerns illegal discharges to the drainage system. These peak

discharges cause the total flows to exceed the capacity of the STP, both in the existing

situation and after upgrading. Because it is not feasible to extend the STP capacity

sufficiently to be able to deal with these peak events, the STP will also be bypassed during

peak flows in future. As a result direct discharge of untreated wastewaters to lake NMK will

keep occurring on occasion. Better prevention of illegal discharges is essential to achieve

improvement of the water quality in NMK.

The second type of peak discharges is the result of rainfall. Reduction of nutrient loading to

lake NMK as a result of rain events requires measures to reduce nutrient input in the

catchment area and measures to reduce the discharge volumes to lake NMK through

diversion of flows via alternative routes. Assessment of the feasibility of both types of

measures should be a focus point for key element of the remediation efforts for lake NMK.

Expand and line main canals

Figure 5.2 gives an indication of the different industrial and residential areas in the NMK

catchment. We have seen that stream 1 is the main drainage route for Madhuban colony,

industrial area #1 and Kattedan industrial area. Stream 2 drains Sri Ram Nagar and the 2nd

private industrial area. The limited capacity of the main streams means the smaller

upstream drains in these areas cannot discharge rainfall runoff, resulting in flooding.


50

Figure 5.2. Catchment areas

The most effective way to improve this situation is to increase the main stream capacities. It

is advisable to construct larger, lined canals that are able to transport at least a T1 rain

event. This way upstream flooding can be minimised. Furthermore the connection between

stream 1 with the pumping station and with the STP should be reopened so that the water

can be treated before it flows to the lake. Stream 1a is an earth canal, which mainly

functions after rain events to transport runoff water. This stream needs to be expanded and

lined and connected to stream 1 or directly to the pumping station because it discharges

waste water.

Connect Nataji Negar and truck area

In reality the flow though stream 3 goes through a series of overland, earth drains (see

appendix I, figure 21). This flow is a combination of runoff, sewage from Netaji Negar and

industrial wastewater from the truck workshop area. Ideally a sewage system would be

constructed to direct these flows to the STP for treatment.

Increase pumping station and STP capacity

Treating all the rainfall runoff is not a realistic option and would ask for a very large STP. An

economically more viable option is to design it to treat the ‘first flush’ of a T1 rain event

because the first flush of a rain event is the most contaminated. It is advisable to expand

the pumping station and STP to transport and treat the estimated dry weather discharge,

including some additional capacity to deal with at least 20% of a T1, 1 hour rain event. This

is equal to about 7 MLD. To transport this volume to the STP in three daily cycles storage

facilities will be needed to hold 7% (2.1 MLD) of the water form a T1 storm

Separate drainage systems

Even with an increased STP capacity, most water from the mixed drains will flow untreated

to the lake. To improve this situation we suggest to start transforming the mixed drainage

system to separate systems for waste water and rainfall runoff. We expect that this will be

difficult for most parts of the system. For stream 2 this will be easier because the connected

area is less complex and already partly connected to a sewage line.

This appendix gives an overview of the results of flow measurements in June 2015.The

sampling and monitoring of flows in Kattedan is part of the upgrading of the Sewage

treatment plant at Noor Mohammed Kunta (NMK), The sampling and monitoring of flows is

needed to assess the volumes of water flowing to the STP and NMK lake and the quality of

the incoming flows.

During monitoring we also assess the quantities of water flowing towards the Kattedan area

from surrounding areas.

Figure 1 gives an overview of the locations of flow measurements.

In July and august monitoring and sampling has taken place. The results will be included in

the final report.

For better understanding of the table:

- In most cases the flows are based on measurement of the flow velocity and cross

section of the channel pipes. At some small flows a bucket is used to determine the

flow.

- Most measurements represent dry conditions. In this period June 13 was a rainy day.

At some locations flow measurements for wet conditions are available (see right

column in table 1).

- The data is used to prepare a water balance (see inception report). It was possible to

calculate a consistent water balance taking into account:

Limited accuracy of flow measurements in general (from our experience an error of

15 % is expected).

The fluctuations in the observed flows during dry conditions (see table 1) are high.

The average flow is based on 4 to 8 individual measurements.

At locations F14 and F15 the flow depends on operation of the STP. If the STP is

operated flow will be measured but afterwards the flow can decrease to 0 l/s.

For location F12 (inflow to NMK lake) to observed flows are low compared to

measurements at other locations. Especially the flows during the first 2 days are

low. This is probably an error in flow measurement of interpretation. If we exclude

these days, the flow at F12 (30.1 l/s) corresponds to the sum of locations F6 and F7

(29.3 + 0.6 l/s).

Measurements at location F20 show a low flow (average 11.6 l/s) compared to the

upstream and downstream location (F4 and F6; average flows 13.8 and 29.3 l/s).

There is no clear explanation for this low flow. We suggest to leave the

measurement for this location (for June 2015) out of the water balance.

- Water flowing in from the truck workshop area west of the STP was not measured in

June 2015. During site visits a small flow was observed. We used data from the GIZ

report in the water balance (average 1.2 l/s).
