Executive Summary
72% of population is dependent on onsite sanitation systems like septic tanks and pits, and
this no. is likely to increase in the wake of Swachh Bharat Mission (SBM).
90% of AMRUT funds allocated to two sectors of water supply and sewerage/septage
management.
CSTF decided to implement a pilot scale faecal sludge and septage treatment plant(FSSTP)
and requested Centre for Science and Environment (CSE) to do prefeasibility study and
prepare DPR.
After prefeasibility study and assessment of proposed sites, Mania Pul site is selected for the
proposed FSSTP
This DPR is prepared for FSSTP of 15 Kilo Litre per Day (KLD) capacity, based on the
current demand
Land requirement and allocated for the facility is around 4000 square metre (sq.m), whereas
the proposed built-up area is around 1500 sq.m and rest of the land would be designated for
horticulture.
Gravity based technology used with following modules: grit chamber, unplanted drying bed,
modified ABR, maturation pond, sand filter and storage tank
The capital expenditure (CAPEX) of the facility for technical modules comes out to be ₹ 63.5
lakhs and for non-technical modules, including office, operator’s room, road, wash area,
parking, landscaping, storm water drains etc. it comes out to be around ₹ 86.1 lakhs. The total
CAPEX of the proposed project comes out to be around ₹ 157 lakhs.
The OPEX of the facility including manpower, electricity, consumables and repair comes out
to be around ₹ 2.87 lakhs per year. The operational expenditure (OPEX) of the vacuum trucks
including fuel, manpower and repair comes out to be ₹ 7.2 lakhs. So, the total expenditure for
operation will be around ₹ 10.07 lakhs/year. Total OPEX for five years would come out to be
₹ 15.85 lakhs.
The total IEC expenditure including trainings and behavior change communication comes out
to be ₹ 24 lakhs for five years.
The revenue generation through collection of desludging fees will be around ₹ 7.8 lakhs and
through selling of compost will be around ₹ 2.7 lakhs. Total revenue generated will be ₹ 10.5
lakhs, hence there will be surplus revenue of around ₹ 43,000/- in year 1. In subsequent years
the operation and maintenance cost is expected to increase and hence desludging fees would
have to be adjusted accordingly.
Katihar Municipal Corporation should implement scheduled desludging in 1 or 2 wards near
the treatment plant.
KMC would eventually have to move towards implementing city wide scheduled desludging
and buy more trucks and implement more FSSTPs in different parts of the city to cater the
increased demand.

1 Introduction
Around 70% of urban population in India is dependent on onsite sanitation systems (OSS), which
need regular desludging. Due to lack of any awareness, motivation, regulation, infrastructure and
governance, faecal sludge and septage (FSS), desludged from OSS, is disposed of anywhere in open
space, open drain or even in water bodies, causing severe problems of environmental pollution,
ground water contamination and adverse impacts on the health of local communities. Hence, effective
management of FSS from OSS like septic tanks and pit latrines has been well recognized by the
concerned ministries of Government of India and different state governments.
1.1 Background
A Policy Paper on Septage Management in India was prepared by the Centre for Science and
Environment (CSE) in 2011 to support the Ministry of Housing and Urban Affairs (MoHUA,
formerly known as Ministry of Urban Development), in preparation of national level policy guidelines
for septage management. Accordingly, MoHUA released an Advisory Note on Septage Management1
in 2013 which delineated the importance of safe management of FSS, its characteristics, proper
collection, transportation and effective treatment for its safe disposal and/or reuse. Finally, the
National Faecal Sludge and Septage Management (NFSSM) Policy2 was announced in 2017 and since
then, this policy has been significantly motivating local governments/ local bodies in taking suitable
measures for effective management of FSS from septic tanks and pit latrines.
The NFSSM policy defines the roles and responsibilities of various government entities and other
relevant stakeholders such as the private sector, civil society organizations and citizens for effective
implementation of FSSM services throughout the country through enabling the synergies among
relevant central government programs such as Swachh Bharat Mission (SBM), Atal Mission for
Rejuvenation and Urban Transformation (AMRUT) and the Smart Cities Mission to realize safe and
sustainable sanitation for all at the earliest. Going one step further, Mission Director (SBM, GoI)
advised all state Mission Directors (D.O. MD-SBM/AA/95/2016 dated 10 June 2017, Annexure 1) to
continue use of AMRUT money for the effective FSSM activities for AMRUT towns while non-
AMRUT ODF cities are allowed to use unspent funds under solid waste management capacity
building for effective FSSM. FSSM has now been duly recognized and included into the Swachh
Survekshan 2018 where the ULBs’ performance will also be evaluated based on the steps taken for
effective FSSM.
CSE has been involved in highlighting the issues of FSSM, and supporting governments at various
levels. CSE with the support of MoHUA and Ministry of Water Resources for River Development
and Ganga Rejuvenation, Government of India has been working on an initiative which is aimed at
capacitating urban local bodies and other stakeholders to help achieve convergence of national
programmes namely - NMCG, AMRUT, SBM in identified flagship town /cities by planning for city
wide sanitation including non-sewered areas and identification of interventions for effective
wastewater and FSSM.

1.2 Rationale for the DPR preparation
The role of CSE in the FSSM is summarized below:
MoHUA identified CSE to support a total of 23 towns (including Katihar) so that they
become flagship towns in FSSM (D.O. MD-SBM/AA/62/2016 dated 30th May 2016,
Annexure 2)
During the City Sanitation Task Force Meeting (CSTF) in Katihar on 11th May, 2016, the
CSTF members requested CSE to carry out site assessment and prepare a detailed project
report (DPR) for the Faecal Sludge and Septage Treatment Plant (Letter no. 850 dated 7th
June 2017, Annexure 3)
During the state level meeting with Principal Secretary, UD & HD, Government of Bihar on
22nd May 2017, state government requested CSE to prepare DPR for the FSSTP in Katihar
(BGCMS/2016/34/01-370 dated 27th June 2017, Annexure 4)
Accordingly, CSE carried out the feasibility study along with the assessment of potential sites
for FSSTP and presented to the CSTF in Katihar on 29th July (MoM, dated 29th July 2017,
Annexure 5).
In this regard, ULB officials (Mayor, ward councilors and ULB engineers) from Katihar Municipal
Corporation (KMC) attended national (Bangalore, Mysore, and Delhi) and international (Malaysia)
exposure visits to successfully implemented FSSTP and also had first-hand interaction with the
technology provider, municipality and beneficiaries.
The DPR is prepared against the above background and submitted to Katihar Municipal Corporation
for their necessary action and perusal.
1.3 Scope of DPR
The DPR is for a pilot scale FSSTP of 15 KLD (Kiloliters per Day) capacity. The details are as
follows:
i. Current sanitation coverage and scenario in Katihar Municipal Corporation (KMC)
ii. Detailed assessment of potential sites for the proposed FSSTP
iii. Techno-economic feasibility for sustainable treatment of FSS

2 About Katihar
Katihar City, the headquarters of Katihar district, is situated in the north-eastern plains of the state of
Bihar. The city has an area of 33.46 sq. km and lies 24 meters above mean sea level. The Katihar
Municipal Council was constituted in 1905 and transformed to Municipal Corporation in 2009. It is
well connected with the rest of the country with Katihar Railway Junction, a strategic railway station
connecting the north eastern part of the country. Katihar is surrounded by Purnea district (Bihar) in
north and west, Malda district and Uttar Dinajpur district (West Bengal) in East, Bhagalpur district
(Bihar) and Sahebganj district (Jharkhand) in South3.
2.1 Demographics
As per the Census of India 2011, Katihar Municipal Corporation [KMC], with a total population of
240,838, is administratively divided into 45 wards. Being an industrial town, KMC witnesses around
1.5 lakh floating population. Out of the total 145 colonies in the city, 10 are planned and the rest are
unplanned.
According to Census of India the population density of the city is 9,437 persons per sq.km which is
quite high as compared to population density of Bihar state i.e. 1,106 persons per sq.km. During the
post-independence period, commerce showed a phenomenal increase with the associated small scale
industrial development, which resulted in the increase of city population. Refer table below for
growth rate pattern:
Table 1: Population growth rate
Census Year Population Growth rate (%)

2001 1,90,873 23.65
2011 226,261 27

2.2 Drainage
River Ganga, Kosi, and Righa are the main rivers in the region. River Ganga flows at about 25 km
from the Katihar city on the western side, while Kosi flows 30 km from the city on the eastern side.
Kosi River merges with Ganga at the south-west boundary of Katihar District. Katihar has alluvial
sandy soil, contributed by the deposition of sand silt by rivers and soils in southern and western part.
The ground water is available at 15 feet and the city experiences water logging during monsoon
season, mainly attributable to its anthropogenic characteristics. The railway line around the city poses
the hindrance to the free flow of water during monsoon season leading to the water logging in the city.
In order to prevent flooding situation, a town protection dam has been constructed in the east of the
city.

2.3 Climate and rainfall
With warm and temperate climate, Katihar observes an annual mean temperature of 24.9°C with 8°C
and 43°C being minimum and maximum temperature respectively. When compared with winter, the
summers have much more rainfall and the city records 1281 mm annual rainfall, mainly JJAS [June,
July, August and September]. Its closeness to the Himalayas in the north, Jharkhand plateau in the
south and a multiple of rivers combined with excellent rainfall gives the city a climate which is
pleasant during most of the year.

3 Sanitation coverage in Katihar
According to Census, 20114 Katihar city had a sanitation coverage of 74.1% while the recent survey
carried out by KMC (for 7 Nischay scheme of Bihar Government) revealed that the sanitation
coverage is only 49.6%. The difference could be attributed to the fact that Census data also included
public toilets, and other systems like night soil disposed in open drains, service latrines etc. while 7
Nischay does not consider these appropriate sanitation systems. The details of sanitation systems as
per Census 2011 are provided below in Figure 2.
Figure 2: Prevalent sanitation systems in Katihar City (Source: CSE, 2017)
3.1 Analysis of FSSM in Katihar
In order to analyze the existing FSSM practices of the city, CSE prepared an excreta flow diagram
(also known as shit flow diagram, SFD). SFD report5 was prepared on the basis of detailed survey
(household, key informant interviews, focused group Discussion with masons, desludgers, and
physical inspection of sanitation facilities) done in Katihar city.
As shown in the Figure 3, 72% of the population of Katihar depends on onsite sanitation systems
[OSS] and remaining population still practice open defecation. Overall, 98% of the excreta is not
being managed safely and is indiscriminately discharged in the local environment6. As the city moves
towards open defecation free status, percentage of population dependent on OSS would further
aggravate.

Based on the income levels of the households, three types of OSS are prevalent in the city. Septic tank
with an outlet connected to open drain is the most common type of OSS within the central wards.
Most of the septic tanks are well designed with three separation chambers along with an outlet. Some
septic tanks are also connected to soak pits. The lower income settlements like slums and squatter
settlements are majorly dependent on pit latrines. Pits are constructed using concrete rings.
Desludging of the OSS is not scheduled as prescribed by Central Public Health and Environmental
Engineering Organisation (CPHEEO) and is only carried out when containment is full or when there
is a back flow. The emptying service is provided by the municipal corporation, and there are no
private players in this business. A record is maintained on daily basis by the sanitary department for
emptying of septic tanks. Emptying service is only provided to households that pay property tax. The
corporation owns three tractor mounted vacuum tankers, two of 3,500 litres capacity and one of 9,000
litres capacity. The emptiers generally do three to four trips per day for which they travel a distance of
12-13 km per emptying trip. During the field surveys, no use of personal protective equipment (PPE)
by the emptiers, was observed during emptying process.

Additionally, manual scavenging is also practiced in areas where there are narrow lanes and
containments are inaccessible.
Currently, sewage and FSS generated in the city is not treated and the faecal sludge and septage
collected by the vacuum tankers is disposed of at an insanitary landfill at Udama Rakha in Ward 45.
Wastewater from 15 wards conveyed through major storm water drains, is also disposed at ward no.
45.

3.2 Quantification of faecal sludge & septage generated in Katihar
Quantification of FSS is done using two methods; a) FSS collection method and b) FSS production
method,
3.2.1 Faecal sludge & septage collection method
According to Census, 2011, 33,879 households (HHs) in KMC have individual household toilets.
Assuming that as we approach towards the SBM deadline of October 2019, 39730 HHs will have
toilets connected to OSS like septic tanks. If emptying cycle of 3 years (according to CPHEEO) is
considered for HHs;
A total of 13244 [39730/3= 13244 HH per year] septic tanks would need desludging per
annum.
Based on 250 working days per year [13244/250 = 53], a total of 53 septic tanks would be
desludged per day.
Considering only 2 cum of FSS per septic tank, total FSS volume comes to 106 cum per day
[53*2=106].
Further, there will be 17 public/community toilets (PT/CT) including the ones constructed during
mission period. Assuming average volume of septic tank of PT/CT to be 10 cum and desludging
period to be of 6 months, a total of 1.2 cum of FSS would need desludging per day. With a 10% extra
load from non-residential properties, it is estimated that a total of 118 cum of FSS is generated per
day in the city that would need desludging.
3.2.2 Faecal sludge & septage production method
As per Census, 2011, population of the city is 2,40,838. If toilets construction as envisaged in SBM is
successfully implemented, everyone would have access to toilet and hence will contribute to FSS
generation either through individual toilet or PT/CT. Considering FSS generation rate of 120
litres/capita/year and three years of desludging frequency with 250 working days in a year, the FSS
production per day comes out to be 115.6 cum ((240838*120*3)/(250*3)). With a 10% extra load
from non-residential properties, it is estimated that a total of 127 cum of FSS is generated per day in
the city that would need desludging.

4 Faecal sludge and septage treatment technologies
The first step for the treatment of FSS essentially comprises of solid- liquid separation where the total
suspended solids are separated from the FSS. The methods generally deployed for separation include
centrifuge, mechanical thickener, geobags and sludge drying beds. The separated wastewater/effluent
can be treated using aerobic and/or anaerobic principles similar to sewage treatment (up-flow
anaerobic sludge blanket reactor, anaerobic filter, sequential batch reactor, membrane bioreactor,
activated sludge process, oxidation ponds etc.). This can be followed by the nutrient removal in
planted horizontal or vertical gravel filter bed. The treated wastewater, depending upon the designated
end-use can be further treated using tertiary methods like chlorination, UV, ozonation or simply in a
maturation pond etc.
The next step for separated total solids is pathogen removal. The sludge can be further dried (with or
without the use of energy) to kill the pathogens. Pathogen removal can also be achieved through co-
composting with municipal solid waste. Depending upon various criteria like availability of land,
availability of financial resources and extent of the treatment level, number of combinations of the
above-mentioned technologies could be used for FSS treatment. The brief of such combinations and
their specifications are listed in Table 3.

5 Assumptions for this Detailed Project Report [DPR]
5.1 Estimation of capacity of FSSTP
This DPR aims to provide techno-economical details of a pilot scale FSS treatment plant. During the
discussions with the sanitary staff involved in operation of vacuum tankers and emptying of septic
tanks, it was informed that on an average, 12 cum of FSS is collected per day from septic tanks. Thus,
this DPR considers a volume of 15 cum FSS per day for the proposed pilot plant, so that the demand
in near future is also taken care of.
5.2 Faecal sludge and septage characteristics
The DPR of FSSTP is based on the following characteristics of FSS.
Table 4: Assumed physico-chemical characteristics of FSS
S. No Parameters Range Assumed value
1 BOD (Biochemical Oxygen Demand) 2,000 to 5000 mg/l 3,500 mg/l
2 COD (Chemical oxygen Demand) 10,000 to 25,000 mg/ l 17,500 mg/l
3 TS (Total Solid) 10,000 to 20,000 mg /l 15,000 mg/l
DPR for Pilot Scale FSS Treatment Plant in Katihar
Page | 15
6 Legal framework and site selection for FSSTP
Following rules are applicable to the FSSTP:
• The Water (Prevention & Control of Pollution) Act, 1974 as amended
• The Air (Prevention & Control of Pollution) Act, 1981 as amended
• The Environment (Protection) Act, 1986
• Solid Waste Management Rules, 2016
• Hazardous and Other Wastes (Management and Trans boundary Movement) Rules, 2016
• Need to obtain Consent to Establishment and Consent to Operate (CtE and CtO respectively)
or No Objection Certificate (NoC)from SPCB/CPCB
Selection of a suitable site for the FSSTP warrants an integrated approach comprising of multiple
social, economic, technical and regulatory criteria. The ownership status of the land is an important
parameter as this would demand additional financial resources. Technical specifications like
availability of agricultural field/ water bodies for the discharge of treated wastewater/ sludge, the
ground water depth, geological formations etc. are also considered for selection of a suitable site.
Based on the compilation of the above information, a matrix was prepared to give score to potential
sites (four no.s) against predetermined key parameters (Maximum score: 100) as shown in Table 5.
Points accrued against each site was tabulated and the list of sites was prepared as per the points. Site
having the highest point was selected as 1st rank.
Shortlisted four sites were compared using the above methodology for assessing their suitability;
1. Chitoria (a total of 19 acre private land located 1.5 km in south of Katihar)
2. Bhasna Pul (a total of 15 acre private land located 3 km in north of Katihar)
3. Mania Pul (a total of 15 acre private land located 3 km in east of Katihar)
4. Durgapur sluice gate (a total of 2 acre private land located in the ward 10 of Katihar)
Annexure 6 shows location of the above mentioned/shortlisted sites. CSE team along with District
Collector, Mayor, Deputy Mayor and other officials of the Municipality visited the above sites. The
physical inspection of the site and surroundings, assessment of the land use of site and nearby lands,
and consultation with the local communities were also done at each site. All potential sites are owned
by private parties and KMC is willing to acquire the land as approved and endorsed by CSTF.
The exercise concluded that the land available near Mania Pul [near NH 84] was the most suitable
site. Thus, this DPR has been prepared for Mania Pul as the site for proposed pilot FSSTP.

7 Proposed FSSTP Modules
Processes proposed in this DPR include separation of floating and other materials from FSS through
screen chamber, dewatering in unplanted filter beds, composting of dewatered sludge and anaerobic
treatment of filtrate. Treatment of filtrate include modified DWWTs (anaerobic settling chambers,
modified ABR/ Anaerobic Filter chambers) followed by sand filter under gravity flow. The layout of
modules is given in Figure 4. The detailed layout of the FSSTP on proposed site is given in Annexure
7.
Figure 4: Layout of treatment modules
7.1 Grit / Screen chambers.
Grit chambers (Figure 5) are useful in segregating floating materials in FSS before it flows in filter
beds. The chamber uses two vertical screens, made from mild steel and coated with anti-corrosive
material, in series. The first screen has a gap of 3 cm between two consecutive bars and the second
screen has a gap of 1.5 cm. With a peak flow velocity of 15 cm/sec to 30 cm/sec the detention time in
the grit chamber is estimated to be of 30 to 60 seconds.
To make best use of the gravity it is proposed to have one grit chamber for every two unplanted
drying beds. As having one grit chamber feeding all the beds, would have led to increase in effective
depth of the last beds, and hence outlet of the effluent would have gone much deeper.
Characteristics of manual bar screen
• The screen is mounted at an angle of 45-700 from horizontal plain
• Bars are usually 1 cm thick and 2.5cm wide
• Minimum approach velocity in the bar screen channel is 0.45 m/s to prevent grit deposition.
• Maximum velocity between the bars is 0.9 m/s to prevent washout of solids through the bars.
DPR for Pilot Scale FSS Treatment Plant in Katihar
Page | 18
A low velocity allows an increased removal of solids but involves a greater solids deposition in the
channel leading up to the beds, which should be avoided. Therefore, the flow velocity should reach, at
a minimum, the self-cleansing velocity (greater than 0.3 m/s for wastewater). The flow should also
not exceed 1 m/s in order to avoid coarse wastes being pulled through the bars due to the strength of
the flow. Area required for grit chamber will be 1 sq. m. The detailed design of grit chamber is
provided in Annexure 7.
Figure 5: Grit chamber (Source: Indiamart.com)
7.2 Drying Beds for dewatering
The natural method of dewatering include filtration of FSS through filter material in planted or
unplanted drying beds. Unplanted drying beds are shallow filters filled with sand and gravel with an
under-drain at the bottom to collect leachate. Sludge is discharged onto the surface of bed for
dewatering. The drying process in a drying bed is based on drainage of liquid through the sand and
gravel to the bottom of the bed, and evaporation of water from the surface of the bed. After filtration,
pollution loads of FSS along with pathogen count gets drastically reduced. Benefit of using drying
beds is minimal O&M cost. Effluent from the filter beds need further treatment for its intended end-
use.
FSS contains both free water and bond water. Free water can be removed easily under gravity through
filter material. Leachate percolates through sand and gravel. This process is significant for FSS that
contains large volumes of free water and is relatively fast, ranging from hours to days.
Bond water can be removed through evaporation and evapotranspiration. Evaporation is through sun
light while evapotranspiration takes place through plant leaves in case of planted filter bed. Plants
uptake such bond water and through transpiration release such water into atmosphere. This process
typically takes place over a period of days to weeks. There is water removal of 50 to 80% by volume
due to drainage, and 20 to 50% due to evaporation in drying beds.
The design as well as the operation of the drying bed is fairly straightforward, provided the sludge
loading rate is well selected and the inlet points for depositing the FSS onto the bed are adequately
designed. Depending on the FSS characteristics, a variable fraction of approximately 50-80% of the
sludge volume drains off as a liquid (or leachate), which needs to be collected and treated prior to
discharge. After reaching the desired extent of dryness, the sludge is removed from the bed manually
or mechanically. Further processing for stabilization and pathogen reduction may be required
DPR for Pilot Scale FSS Treatment Plant in Katihar
Page | 19
depending on the intended end use option. When considering the installation of a drying bed, the ease
of operation and low cost needs to be considered against the relatively large footprint and odor
potential.
Figure 6: Unplanted drying bed (Source: FSM Book)
Climatic conditions affecting the operation of unplanted drying beds include the following:
• Humidity: High humidity reduces the contribution of evaporation to the drying process;
• Temperature: Higher temperatures, also in combination with relatively low humidity and high
wind, will enhance the total amount of water removed via evaporation;
• Rainfall: In locations where there is frequent rainfall that too for longer duration, a drying bed
may not be very effective. Pronounced rainy seasons can be accommodated for by not using
the beds in that period, or by covering them with a roof. Rainfall will rewet the sludge, hence
affecting drying period of the sludge.
The design of proposed sludge drying bed is provided in Annexure 7.
7.2.1 Sand and gravel layers
Layers of sand and gravel are applied on top of the drainage system. When constructing drying beds,
it is essential to use washed sand and gravel in order to prevent clogging of the bed from fine
particles. The gravel layers function as a support and there are typically two or three layers with two
different diameters of gravel. The lower layer usually contains coarser gravel with a diameter of
around 20-40 mm and the intermediate layer contains finer gravel with a diameter of around 5-15 mm.
A sand layer is placed on top of the gravel. The sand layer enhances drainage and prevents clogging,
as it keeps the sludge from lodging in the pore spaces of the gravel. The diameter of the sand is crucial
as sand with a larger diameter (1.0-1.5 mm) can result in the relatively fast accumulation of organic
matter, thereby increasing the risk of clogging. This risk is reduced if sand with a smaller diameter
(0.1- 0.5 mm) is used (Manga et al., 2009)7. When selecting sand for the bed, it is important to note
that the sand will need to be replaced occasionally, as a certain amount of the sand is bound to the
sludge and will therefore be removed when the sludge is removed. It is therefore recommended that
the sand that is chosen must be easily available.

performance of sand drying beds used for FSS management. Water Science and Technology Available Online
26 September 2016, DOI: 10.2166/wst.2016.451
DPR for Pilot Scale FSS Treatment Plant in Katihar
Page | 20
The sand also needs to be replaced when there is a build-up of organic matter and the bed starts to
clog. Manga et al. (2009) observed a link between the rate of clogging and the rate of organic matter
build-up on the sand. As organic matter builds up faster on sand with larger particles, a bed filled with
larger diameter sand is more likely to clog. Cofie et al. (2006)8 had to replace the sand twice in a
series of 8 dewatering cycles over 10 months due to clogging in a pilot scale implementation.
7.2.2 Sludge removal
In order to remove the sludge effectively, it needs to be dry enough that it can be shoveled. The drying
time of a specific sludge type depends on a number of factors, one of which is the sludge dewatering
resistance. The higher the sludge dewatering resistance, the lower the drainage rate which leads to a
prolonged drainage time. Sludge is removed mechanically or manually, with shovels and wheel
barrows being the most common manual method.
7.3 Effect of Climatic conditions and hydrology
Ground water level: The design can be implemented even in areas having high ground water table.
Depth of the treatment chamber would be only 2 m for anaerobic settling chamber and 1.5 m for
facultative chambers. Treatment chambers of such depth can be easily constructed. Bottom of all the
chambers would have RCC. Therefore, there would be no chance of ground water pollution.
Rainfall pattern: Drying beds will have transparent waterproof shed and entire waste water treatment
system would be covered, except for maturation pond. No rain water will interfere with the treatment
system. Therefore, rainfall will not affect the system.
Wind direction: Wind direction does not have any effect on treatment system. However, for filter
beds, it may have positive effect on drying of sludge on sand filter beds.
7.4 Calculation of sludge loading rate, size and number of beds
7.4.1 Sludge loading rate
The sludge loading rate (SLR) is expressed in Kilogram Total Solids per sq.m per year [Kg TS/
m2/year]. It represents the mass of solids dried on one m
2 of bed in one year. The total amount of
sludge to be dried, sludge loading rate, bed surface area and loading depth can only be an estimate and
will vary with the local conditions. However, a range of sludge loading rates which typically vary
between 100 and 200 Kg TS/m2/year in tropical climates, with 100 for poorer conditions and 200 for
optimal conditions is generally observed. Optimal conditions comprise a low humidity, high
temperature, a low amount of precipitation, and stabilized sludge. In Katihar, rainy season is for
longer period and hence a loading rate of 150 kg TS / m2 is taken into consideration.

7.4.2 Size and number of beds
Assumptions
C = Average Total Solid of sludge = 20 g/ l
Q = Incoming FSS per day = 15 cum
T = No. of delivery days in a year =250 days
M = Sludge load in Kg TS / year= C.Q.T. = 20 X 15 X 250 = 75,000 Kg / Year
Total area required for drying beds = 75,000 / 150 = 500 m2
Assumed height of the total sludge = 0.3 m
Area required for a drying bed for one day loading = 15/ 0.3 = 50 m2 i.e., 10 m X 5 m
No. of required beds- 500 / 50 = 10 nos.
7.4.3 Loading frequency of an unplanted drying bed
Optimization of loading frequency on filter beds is an important factor for smooth functioning of
drying beds and for improved quality of dried sludge. To determine optimum loading frequency, two
factors are to be considered; (i) total load of sludge in a bed should not be more than the designed
capacity of loading in a year (in the present case it is 150 kg TS/ m2
/ year and (ii) there should be
sufficient time for sludge drying and also for removal of dried sludge / manure. For TS of FSS of 20
g/ l, a bed area of 50 m2 can be loaded for 25 days in a year.
Each bed of 10m x 5m area is meant to take total load 15 cum of FSS for a day. All 10 beds will be
grouped in 2 sets. In the 1st cycle, loading from bed no.1 to 5 will be done in sequence for 2 weeks.
Thus, each bed shall get time of at-least six days before next loading, i.e., a total of 14 days will be
required to complete the first cycle. It should help percolate maximum liquid part of the septage and
allowing the rest to evaporate. After two weeks, the 2nd
cycle of loading will start for the 2nd
set of
beds nos. 6-10 in sequence for another two weeks. Thereafter, 3rd
cycle will start for the 1st set of beds
for subsequent two weeks. Similarly, the 4th cycle of loading for the 2
nd set (no. 6-10) will follow for
two weeks.
Since there would be 26 such cycles, thus total number of possible days of loading in a year would be
260. Here, number of working days in year is taken 250. Thus the cycles will be completed 10 days
earlier. By the time the 2nd
cycle will be completed (in 14 days), sludge from the 1st set of beds will be
sundried and excavated / removed.
7.5 Anaerobic treatment of filtrate
The basic design for treatment of filtrate consists of:
i. Anaerobic Settling Chamber/Tank: Filtrate from filter beds is given retention time of one day
in an anaerobic settling tank for settling and digestion.
ii. Facultative Chamber/Tank: The filtrate from settler is treated in facultative tank (modified
Anaerobic Baffled Reactor with filter).
iii. Maturation Chamber/Tank: Treated filtrate from facultative chamber is polished in maturation
chamber, sand filter and then stored in water tank. The overflow is discharged to storm water
drain .
DPR for Pilot Scale FSS Treatment Plant in Katihar
Page | 22
7.5.1 Anaerobic settling chamber
Leachate from unplanted drying beds is low in organic matter compared to domestic wastewater and
direct discharge into the facultative tank might be possible as the solid fraction is relatively low.
However, the ammonia concentration can still cause a problem. Therefore, a settling tank to make
solids settle before flowing into facultative tank is needed.
Size of tank—For 15 cum volume of FSS, a size of 2 m X 4 m X 2.5 m will solve the purpose. This
would remove 30-40 % of BOD and produce limited odor when loaded with 250–350 gm BOD /m3
/day.
7.5.2 Facultative tank [Modified Anaerobic Baffle Reactor]
In facultative tank (or modified ABR) coir ropes and used plastic bottles are used as substratum for
bacterial growth. Principle of ABR technology is based on increasing HRT (Hydraulic Retention
Time) by letting wastewater flow through baffle chambers. The upward and downward flow is
maintained through PVC pipes in the chamber. Further, for the growth of bacteria, stones are used in
the chambers.
Proposed Modifications: Instead of vertical spiral flow through PVC pipes, horizontal flow through
chambers has been proposed. Horizontal spiral flow of waste water will take more time to flow from
one chamber to another than vertical spiral flow, resulting in more settling time and consequently
bacterial action with no turbulence in flow. Further, cost of the system will also be lower as no PVC
piping would be required. Instead of stones in chambers as filter media, thick coir ropes and/or plastic
bottles will be used. In such case media will be used without affecting HRT. In case of stones, HRT is
reduced, depending on the volume occupied by stones. Coir ropes have very rough surface area with
much longer life in waste water due to its lignin content. Several such ropes of length of 1.2- 1.4 m
can be tied together with a stone and can be put into the chamber. Thus, coir ropes will remain
submerged floating, hence providing more space for bacterial growth. Similarly used plastic bottles
with bottom cut can be used as beads to make a string. Length of the string should be 1.2 -1.4 meters
from the bottom. Such strings should be tied with a stone or brick and put in the chambers. Thus,
bottles will be submerged and float under the water and act as growth media for the bacteria. Length
of the string should be lower than the water column height to avoid it flow on water surface. Number
of such bottles should not be less than 50 per sq. m.
Number of such facultative spiral chambers would be 4 followed by one maturation chamber. Total
retention time in the facultative chambers would be of 14 days. Depth of facultative and maturation
chamber would be of 1.5 m each. The design of proposed ABR is given in Annexure 7.
Whole system will be covered with slab so that bacterial biomass is not flushed away during rains. In
case of covered chambers, the condition would be anaerobic and not facultative. Effluent from the last
chamber will be filtered through sand under gravity. Treated effluent after sand filter will be suitable
for use in horticulture/agriculture.
Advantages of the proposed modification of technology
• Under the proposed technology waste water will flow horizontally and spirally from one
chamber to another, taking much longer time without any turbulence. Therefore, effective
HRT will increase and there would be more settling of solid materials in the chambers.
DPR for Pilot Scale FSS Treatment Plant in Katihar
Page | 23
• Coir ropes have a rough surface and does not degrade in waste water for years. Number
of such strings should not be less than 50/m2. Higher number will help in increasing
efficiency.
• Since such growth media would be throughout the water column, it would help increase
growth and multiplication of bacteria without affecting HRT.
• Removal of such growth media, when required, would be very easy as ropes/ bottles with
strings can be easily pulled out.
Advantages of the anaerobic system
i. There is no or very low recurring / O&M cost of the system
ii. Design can uptake higher organic load without affecting the function of the system
iii. Quality of final effluent will meet the norms of CPCB as per the notification of the gazette of
MoEF&CC
Limitation
• Land requirement is slightly more than aerobic condition, but much less than the technologies
reviewed elsewhere in this document.
7.6 Land requirement for 15 cum FSS treatment facility
Land requirement for treatment of FSS of 15 cum per day will be around 1000 sqm. Including
approach road, office area, compost unit, operator room, parking area, wash area, drainage network
etc. it comes out to be around 1500 sqm. The total area of the site is around 4000 sqm. Hence 2,500
sqm area would be used for landscaping and internal pathways including staircases.

Treated effluent will be reused for horticulture/agriculture on site and excess water can be sold or
disposed in the open drain to the nearby water body. The treated FSS can be stored in sludge storage
yard and ULB can arrange for selling it to farmers through tender or mutually agreed terms and
condition. To improve the quality of compost, co-composting of FSS with municipal solid waste can
be considered in future. The space provided for composting and storing FSS is large enough to
consider co-composting. MoHUA, Government of India has fixed the price for manure from
municipal solid waste @ ₹ 1500 / ton. However, cost of manure from FSS in market is much higher
[₹ 3000- 4000 / ton].
10.2 Proposed bussiness model
There can be two sources of revenue for this project; a) Emptying fees charged to the user, b)
Revenue generated by selling the compost and/or treated effluent. Compost from FSS will have good
market value as compared to sludge from sewage treatment plant.
For increasing demand of compost from the local farmers, ULB should demonstrate the increase in
productivity of crops and vegetables by using the compost and treated water onsite and nearby fields.
In the present pilot scale plant of 15 cum FSS treatment, following is the calculated income generation
from compost:
Each unplanted drying bed is of 50 m2 loaded with 150 kg TS/m
2 of FSS per year.
Total FSS loaded in a year per bed = 150 x 50 = 7500 kg
Total FSS loaded on 10 beds = 75000 kg
Since dry FSS / compost contains 25 % moisture, total weight would be =100000 kg.
Assume 10 % loss during filtration and handling, Net compost available = 90000 kg (90 tons)
At conservative side, selling price at the site is assumed ₹ 3000 / ton (₹ 3 / kg)
Selling price of total compost = 90 X 3000 = ₹ 2,70,000 per year
Revenue generated from desludging is around ₹ 65,000/- per month. Considering 4 trips/day of
smaller tankers (3000 liters) and 2 trips of bigger tanker (9000 liters) in one month. Desludging fees
for smaller tanker is taken ₹ 750/trip and for that of bigger tanker is taken as ₹ 2,500/trip as per KII
done with sanitary inspector. Total revenue possible from desludging = ₹ 7,80,000 per year.
Total Revenue = Resource recovery from compost + Desludging revenue
= 2,70,000 + 7,80,000
= ₹ 10,50,000
The cost of maintenance of tankers comes out to be ₹ 60,000/- in one year
The cost of fuel for all tankers comes out to be ₹ 10,000 per month, i.e. ₹ 1,20,000 in one year
The salary of drivers and labor working in desludging operations comes out to be ₹ 45,000 per month,
i.e. ₹ 5,40,000 in one year.
The cost of operation and maintenance of the site comes out to be ₹ 2,82,000 in first year.
Total Expenditure = 60,000 + 1,20,000 + 5,40,000 + 2,87,000
= 10,07,000/-

Page | 27
Thus, it is expected to generate surplus revenue of ₹ 43,000/- in first year. As the expenditure is going
to increase due to inflation, the desludging fees and selling price of compost should be adjusted
accordingly every year.

11 Way forward
Structural drawings shall be prepared by the contractor based on the designs proposed in the DPR
before implementation of the same. Refer Table 8 for proposed milestones and timeline for
implementing FSSM in Katihar city for improving citywide sanitation.
The city produces around 12 KL of septage per day based on the current demand. But if the OSS are
timely desludged, the city shall produce 120 KL of FSS each day (assuming everyone will have
access to toilet), as discussed in section 3.
Therefore, once the treatment plant is up and running the KMC should try scheduled desludging in
one or two wards, by providing 1st desludging at a nominal cost and properly monitoring the date and
volume of septage desludged from each property. In three years each property should have been
desludged once, and the cycle can continue. For economic viability the ward close to the treatment
plant should be selected and a nominal sanitation fee of ₹ 25/month can be charged to each household
either through water bill or through property tax etc. Once the model is successful, it can be replicated
for the whole city with more trucks and treatment facilities of cumulative capacities of 105 KLD.
