Brief about Project

Pragati Maidan is a venue for large exhibitions and conventions in New Delhi with

65,000 m2 of existing exhibition space is now re-develop into Integrated Exhibition-

cum-Convention Centre (IECC) with Approx. 3,61,688.809 m2 of built up area having

Convention Center & Exhibition Halls building development in Phases-1 facilities like

car parking for visitors a single basement also planned. Proposed development will

become Delhi's & North India's largest exhibition centre owned and managed by India

Trade Promotion Organization (ITPO) The design comprises of an iconic convention centre& exhibition- halls. Considerations

have been made for the use of environment friendly materials to achieve Green

Building Features. Overall layout of the project includes convention centre, exhibition

halls, Restaurants, Business centre, open exhibition space with parking basement.

The existing buildings were constructed and also became operational prior to the

publication of EIA Notification 2006. Therefore, the existing buildings did not attract

applicability of to obtain Environmental Clearance from SEIAA/MoEFCC and no

environmental clearance was issued. Accordingly, the issuance of certified monitoring

report by Regional Director of MoEFCC is not applicable for the existing buildings. The

construction of existing buildings was done after getting approval from concerned

departments of Delhi.

Topography Physically the natural capital territory of Delhi can be divided into 3 segments - the

Yamuna flood plain, the Ridge and the Plain. The entire area of the national capital

territory of Delhi is categorized as Bangar or the plain. The land of the plain is mostly

fertile The entire area of the site is monotonously flat. The project area possesses plain terrain.

Highest elevation levels is 692 feet & the lowest levels is 685 feet

Water Environment (Requirement and Consumption)

Construction PhaseDuring the construction phase the water requirement (approx. 1900 ML) will be met from

Private water or treated wastewater from Nearby STP. No ground water will be extracted.

Hence, there will be no impacts on ground water environment during construction phase.

Operational Phase

Total water requirement for redevelopment of IECC Project (Existing + Proposed) is 3,975

KLD. Total domestic water requirement is approx 1,574KLD. The main sources fresh water

will be

DJB Registered tube wells within ITPO Complex.

However the secondary sources of the water are

Tanker supply (For Emergency Use only) Treated Effluent from an external centralized sewage treatment Plant

The existing source of water for the project is DJB. There are two existing metered tapings

from 450 mm diameter water pipe line, one of the connections is of 50 mm diameter and is

near gate no. 3 of ITPO while the other connection is of 150 mm diameter and is near gate

no.7. Water is supplied 24 x 7 to Pragati Maidan. There are existing 5 bore well and

additional 2 bore well will be dug to fulfill the present water demand.

Detail of water requirements for various uses is given in below table. Efficient dual flushing

fixtures will be provided for conservation of fresh water. The demand may vary depending on

the water conservation methods employed by the facility, which may include use of water

efficient fixture, use of dishwashers, water auditing and metering etc

Total quantity of wastewater generation will likely to be 2,295KLD. The generated sewage will

be collected and treated in the in-house Sewage Treatment Plant of 2,200 KLD capacity. The

treated wastewater will be re used for flushing and gardening and HVAC cooling. Water

Quantity of sewage generated during operational phase shall be 2,295KLD. Thus the sewage

will be treated through sewage treatment plant of capacity 2,200 KLD. The treated sewage

will be re used for flushing (1,036 KLD) greenbelt development (256 KLD) and for HVAC (632

KLD during Non Monsoon Season and 376 KLD during Monsoon Season).

Figure 4 : Water Balance diagram during Monsoon Season

Sewage Treatment TechnologyThe design of sewage network shall be done in accordance with the CPHEEO guideline, NBC

guidelines and reverent Indian Standards. Sewage generation is assumed to be 100% of

flushing water and 80% of domestic water.

The following parameters/ site conditions shall be kept in mind when designing the sewage,

Sludge and storm water drainage system.

Natural slope of the area. Layout of different facility in the complex; Possibility of using complete or part of the existing sewage network; Sub-soil water table; Provision of Sewage lifting station; ( if required) Provision of venting arrangement for manholes; Construction of manholes & laying of pipes considering ground condition; Termination of vent cowl at terrace level; Provision of adequate slope for horizontal header in the under slung pipes especially

for public toilets Sewage flow starts with fractional capacity and builds up to full capacity in due

course. An operational plan to meet this demand from a low flow to full flow will be

part of the design.

A summary of board design parameters to be adopted for designing Sewage supply system is

given below.

Technology Proposed- MBR (Membrane Bio Reactor)The MBR is a suspended growth-activated sludge system that utilizes micro porous

membranes for solid/liquid separation instead of secondary clarifiers.

An external sewage network shall collect the sewage from all units, and flow by gravity to the

proposed sewage treatment plant.

Following are the benefits of providing the Sewage Treatment Plant in the present

circumstances:

Reduced net daily water requirements, source for Horticultural purposes by

utilization of the treated wastewater. This shall consequently lead to a lower

withdrawal from the underground aquifer water sources.

Reduced dependence on the public utilities for water supply and sewerage

systems.

Sludge generated from the Sewage Treatment Plant shall be rich in organic

content and an excellent fertilizer for horticultural purposes.

The STP is being proposed with state-of-the-art membrane separation technology called as

Membrane Bio-Reactor (MBR) which can produce very good quality with highest possible

bacterial reduction without adding any chemicals. MBR (Membrane Bio Reactor) is the latest

technology in wastewater treatment. MBR has many advantages such as higher quality of

treated water, smaller space for installation and easier operation compared to conventional

activated sludge process.

Designed to produce high quality treated water from wastewater the Membrane Bio Reactor

(MBR) is among the latest technologies in biological treatment.

The characteristic of the MBR process is the use of revolutionary submerged polymeric

hollow fibre membranes in the biological process water tank, so as to produce high quality

permeate from domestic sewage, primary and secondary waste water, cooling tower blow

down etc. The MBR is also ideal for retrofitting/augmenting capacity/quality of existing

wastewater plants.

The hollow fibers are combined into bundles and wound around a carrier cartridge, which

gives the membranes the required strength and allows for high-pressure air scour for

cleaning. The MBR can handle very high sludge concentrations in the aeration tank because

of which the size of the aeration tank reduces four to five folds. As the membrane acts as a

fine filter, it does not require any further treatment using sand filters, activated carbon

filters, etc. The MBR is available in standard and customized modules.

Process Description

Figure below shows the principle of the filtration for the flat sheet type submerged

membrane. Activated sludge in the aeration tank is clearly removed by the flat sheet type

submerged membrane. The membrane module consists of housing, aeration diffuser;

permeate water manifold and membrane elements. The membrane element consisting of flat

sheet membranes sandwiching a support panel is set up vertically. Feed water including

activated sludge is filtrated by flat sheet membranes with pore size of 0.1 micron meter. The

air bubbles supplied from the bottom of the membrane elements continuously scour off cake

of activated sludge accumulated on the membrane surface. This is continuous filtration

operation. The air bubbles are also used for the biological reaction to decompose organic

substances included in the raw sewage.

Figure 5 : Schematic Diagram of MBR Technology

MBR Module

The material of the membrane is PVDF (Poly vinylidene fluoride). PVDF is fluorine polymer,

which has high stability for chemicals and good physical strength. The form of membrane is

fibre reinforced flat sheet membrane. The membrane has small and uniform pore size.

Therefore, the rejection property of this membrane is excellent. Almost all particles with sizes

more than 0.1 micron meter can be removed effectively using this membrane.

Operation

Sewage from main drain line is collected through gravity pipes into a screen chamber.

This manually cleaned screen is provided to remove floating and big size particles, which

may choke the pumps and pipe lines.

Screened sewage is then passed through equalization tank to homogenize the sewage

quality and also even out flow fluctuations and feed sewage of uniform quality at constant

rate to subsequent treatment units. Air mixing is also provided to mix the contents of the

equalization tank. A coarse bubble aeration grid is provided to distribute air uniformly at

the base of the equalization tank.

After above treatment, raw sewage is fed into aeration basin.

In aeration tank, MLSS (mixed liquor suspended solids) in the range of 12000 to 15000

mg/l are maintained. The high amount of bacteria gives better and complete removal of

organic matter from the raw sewage in relatively small area. Oxygen required for the

bacteria is supplied through the blower. The air is used both for scouring of membranes

and supplying oxygen to bacteria.

The filtration is carried out by the suction pump directly sucking permeates water. The

permeate water produced is clear and devoid of bacteria and viruses to the minimum

levels.

As the membranes are continuously under operation, they are polluted with organic or

inorganic substances. Hence, chemical cleaning is carried out once in two to three

months for removing substances polluting and clogging the membranes. Normal cleaners

used are sodium hypo chloride and citric acid.

Sewer System

The alignment and slope of the sewer line will follow the road network, drains or natural

ground surface and will be connected to the trunk sewers. The discharge point will be a

treatment plant, a pumping station, a water course or an intercepting sewer. Pumping

stations would be provided at places where the natural slope of the terrain is insufficient to

permit gravity flow or the cost of excavation is uneconomical to do the same

treated wastewater pipes will be laid in conduits wherever road crossings are expected. Thus

no leaching of treated sewage into nearby water courses shall take place. Supervisors will be

employed for overall operation & maintenance of water supply, waste water treatment and

other utility services.

Rainwater Harvesting and Strom Water DrainA rainwater harvesting system comprises components of various stages -transporting

rainwater through pipes or drains, filtration, and recharging the ground water through

tanks. Percolation structures will be constructed for ground water recharge.

Runoff from the first spell of rain carries a relatively large amount of pollutants from the air

and catchments surface so the system will be provided with a filtration pit consisting of

layers of sand, gravel and pebbles of relevant sizes to remove impurities from the collected

rainwater.

Need for Rainwater HarvestingSurface water is inadequate to meet the daily demand and we have to depend on groundwater.

Due to rapid urbanization, infiltration of rain water into the sub-soil has decreaseddrastically and recharging of ground water has diminished.

Rainwater harvesting prevents the flooding of low-lying areas in the site.

Rainwater Harvesting NetworkRain water harvesting structures will be constructed all around the compound wall to collect

rain water. Excess storm water will be allowed to drain into the external storm drain.

Rain water harvesting has been catered to and designed as per the guideline of CGWA. Peak

hourly rainfall has been considered as 11 mm/hr. The recharge well of 10 mtr dia and 10

mtr depths and 4 mtrs width will be constructed for recharging the water. The bottom of the

recharge structure will be kept 5 m above this level. At the bottom of the recharge pit, a filter

media is provided to avoid choking of the recharge bore.

The pit will be filled with rounded gravel 5 to 10 mm size. The sectional detail of the

proposed rain water recharge structure is provided in below figure.

The path ways around the harvesting lines will be graded to facilitate drainage into trenches

proposed around the compound. Recharge wells/structures are envisaged along the path of

the storm water drains for rain water recharging & surplus water from the recharge

wells/structures shall be diverted to the storm water drainage network.

The collected storm water will be allowed to percolate to the sub-soil by suitably designed

percolation structures. The structures will be designed based on the soils percolation

capability. The subsoil water table is high in these areas and however harvesting structures

with bores will be provided.

Percolation structures of suitable numbers will be provided for recharge of ground water

potential. A total of 10 rain water harvesting structures will be constructed. The quantity of

storm water load for the proposed construction project is given below.

Efficacy of Rain Water HarvestingThe area of site has the water table at 3.0 M. It is not advisable to recharge aquifer by rain

water in areas with water table less than 8.0 M. In this case, following is recommended: -

Use the storm water to recharge lake next to Old Fort, subject to approval by ASI &additional cost of connectivity. This will automatically mean water harvesting throughpercolation.

Use the storm water to run chillers cooling towers after tertiary treatment during themonsoons. The treated effluent being received from DJB will not be drawn during thisperiod. The facility management team must ensure the same.

Parking DetailsAdequate provision will be made for car/vehicle parking at the project site. There shall be

adequate parking provisions for visitors so as not to disturb the traffic and allow smooth

movement at the site.
