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 waste water. 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.

a. Waste Water Details

(a) Daily load : 427 KLD

(b) Duration of flow to STP : 24 hours

(c) Temperature : Maximum 32oC

(d) pH : 7-8.5

(e) Colour : Mild

(f) T.S.S. (mg/l) : 200-450 mg/l

(g) BOD5 (mg/l) : 250-400 mg/l

(h) COD (mg/l) : 600-800 mg/l

b. Final discharge characteristics

(a) pH : 6.5 to 8.5

(b) B.O.D. : <10 mg/l

(c) C.O.D. : <30 mg/l

(d) Total Suspended Solids : <50 mg/l

Treatment technology is based on the Submerged Aerobic Fixed film reactor. The main advantages

of SAFF technology is that having the combination of the fixed film technologies and fine bubble

diffused aeration techniques. With the higher surface area of bio media, higher organic loading

rates are enabled, thus reducing the overall size required of the aeration tank.

Raw sewage will be collected under gravity into the sump after allowing to pass through the bar

screen. The bar screen, by removing coarse solids from the sewage help in protecting the raw

sewage pump. The raw sewage sump, through temporarily holding the incoming sewage facilitates

both pumping of sewage through the STP and dampening the flow variation in the received sewage.

The sewage collected in equalization tank is pumped and passed through the Aeration tank. From





the aeration tank, the raw sewage goes to a settling tank (Clarifier) to allow gravity separation of

the mixed liquor suspended solids from the treated wastewater. Settled MLSS are then recycled to

the aeration tank. Excess sludge from the system is drained out. The excess sludge will be

dewatered and used as manure for green belt development. The effluent coming after treatment will

be passed through the flocculation cum settling tank to capacity. Treated effluent coming out from

the tank will be passed through softening plant followed with disinfection.

Figure 3: STP Design

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.





RAIN WATER HARVESTING

The storm water collection system for the premises shall be self-sufficient to avoid any

collection/stagnation and flooding of water. The amount of storm water run-off depends upon many

factors such as intensity and duration of precipitation, characteristics of the tributary area and the

time required for such flow to reach the drains. The drains shall be located near the carriage way

along either side of the roads. Taking the advantage of road camber, the rainfall run off from roads

shall flow towards the drains. Storm water from various plots/shall be connected to adjacent drain

by a pipe through catch basins. Therefore, it is proposed to provide 4 RWH pits at selected

locations, which will catch the entire run-off from site.

1) Since the existing topography is congenial to surface disposal, a network of storm water

pipe drains is planned adjacent to roads. All building roof water will be brought down

through rain water pipes.

2) Proposed storm water system consists of pipe drain, catch basins and seepage pits at regular

intervals for rain water harvesting and ground water recharging.

3) For basement parking, the rainwater from ramps will be collected in the basement storm

water storage tank. This water will be pumped out to the nearest external storm water drain.

4) Peak Hourly rainfall of 40 mm/hr shall be considered for designing the storm water drainage

system.

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

rainfall has been considered as 45 mm/hr. The recharge pit of 3 m diameter and 4 m depth is

constructed for recharging the water. Inside the recharge pit, a recharge bore is constructed having

250-300 mm diameter with 160 mm PVC slotted pipe up to a layer where sandy aquifer/ deeper

aquifer permeable layer exist. The bottom of the recharge structure will be kept 5 m above this

level. At the bottom of the recharge well, a filter media is provided to avoid choking of the recharge

bore. Design specifications of the rain water harvesting plan are as follows:

Catchments/roofs would be accessible for regular cleaning.

The roof will have smooth, hard and dense surface which is less likely to be damaged

allowing release of material into the water. Roof painting has been avoided since most

paints contain toxic substances and may peel off.





All gutter ends will be fitted with a wire mesh screen and a first flush device would be

installed. Most of the debris carried by the water from the rooftop like leaves, plastic bags

and paper pieces will get arrested by the mesh at the terrace outlet and to prevent

contamination by ensuring that the runoff from the first 10-20 minutes of rainfall is flushed

off.

No sewage or wastewater would be admitted into the system.

No wastewater from areas likely to have oil, grease, or other pollutants has been connected

to the system.

Calculations for storm water load -

Roof-top area = Ground Coverage = 5685.191 m2

Green Area = 13,020.734 m2

Paved Area = Total Plot Area – (Roof-top Area + Green Area)

= 30,480.00 – (5685.191 + 13,020.734)

= 11,774.075 m2

Run-off from green and paved area:

Green Area = 13,020.734 × 0.045 × 0.1

= 58 m3/hr

Paved Area = 11,774.075 × 0.045 × 0.75

= 397 m3/hr

Total Run-off from green and paved area = 397 + 58 = 455 m3/hr

Taking 15 minutes retention time, total volume of storm water = 455/4

= 114 m3

Taking the effective dia and depth of a Recharge pit 3 m and 4 m respectively, Volume of a single

Recharge pit = π r2h = 3.14 × 1.5 × 1.5 × 4 = 28 m

3

Hence no. of pits required = 114 / 28 = 5.083 Pits = 4 pits

4 Rain Water Harvesting pits are proposed for artificial ground water recharge.





Figure 4: Rain Water Harvesting Pit Design

Run-off from roof top:

Monthly rain water harvesting potential of roof-top area = Roof-top area × Maxm

monthly

rainfall (m) × runoff coefficient

= 5685.191 × 0.10 × 0.9

= 512 m3

Considering storage facility for 2 days run-off = 512/15

= 34 m3

Volume of a tank (3 × 2 × 4 m) = 24 m3

Hence no. of tanks required = 34/24 = 1.4

2 tanks are proposed for harvesting run-off from rooftop area.

degradable and Non Bio-degradable) are proposed to be provided at the strategic

location within the complex.

4. Litter bin will also be provided in open areas like parks, etc.

Treatment of waste

Bio-Degradable waste

1. Bio-degradable waste will be subjected to composting through Organic Waste Converter to

form manure for use in gardening/horticulture.

2. STP sludge is proposed to be used as manure.

3. Horticultural waste is proposed to be composted and used for gardening purpose.

Recyclable waste

1. Grass Recycling – The cropped grass will be spread on the green area. It will act as manure

after decomposition.

2. Recyclable wastes like paper, plastic, metals etc. will be sold off to recyclers.

Non-Recyclable waste

Non-Recyclable waste will be disposed through a local approved agency. The solid waste

management scheme for Operation Phase is depicted in the figure below:





Figure 6: Solid Waste Management Scheme (Operation Phase)

Organic Waste Converter

A waste converter is a machine used for the treatment and recycling of solid and liquid refuse

material. A converter is a self-contained system capable of performing the following functions:

pasteurization of organic waste; sterilization of pathogenic or biohazard waste; grinding and

pulverization of refuse into unrecognizable output; trash compaction; dehydration.

Benefits of organic waste converter:

1. Large quantity of solid waste is converted to manure in a very short period

2. Manure can be used as compost for gardening

3. Machine requires less space and the efficiency is high

4. Manpower and maintenance is very less

5. This is one of the latest techniques of managing biodegradable solid waste.





Operation cost of OWC:

Organic Waste Converter - 300 (Dim. 3m × 4m) is proposed to be used for composting waste

120kg/batch or 3000 kg/day & it requires electricity of about 13.5 HP.

No. of batches /day = 3000/20 = 150

No. of batches to convert 1697 kg/day = 1697/20 = 85

Monthly per capita Operation Cost of OWC:

The operating cost of OWC-300 = 90,000 INR/month

Cost/day = 90,000/30

= 3000/- (i.e. 30 batch/day = 3000/-)

1 batch/day cost = 3000/30

= 100 INR

Cost for 85 batch/day = 85 × 100/-

= 8500/-

Monthly operating cost = 30 × 8500

= 2,55,000/-

Total residential population of the project = 5643

Operating cost of OWC-300 = 2,55,000 INR/month

Monthly per capita cost

= Monthly operating cost/Total Residential population of the project (i.e. 5643)

= 2,55,000/5643

= INR 45/month

GREEN AREA

The total green area measures 13,020.734 m2 (41 % of plot area) which includes area under

greenbelt plantation, avenue plantation and parks.
