circumstances:

• Reduced net daily water requirements, source for Horticultural purposes by utilization of

the treated waste water.

• 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.

(b) Oil & Grease : <10 mg/l

(c) B.O.D. : <20 mg/l



(d) C.O.D. : <100 mg/l

(e) Total Suspended Solids : <10 mg/l

c. Treatment Technology

Treatment Technology

The technology is based on attached growth aerobic treatment followed by clarification by a tube

settler. Lime will be dosed in for suppression of foaming tendencies. The clarified water will be

filtered in a pressure sand filter after dosing of coagulant (alum) for removal of unsettled

suspended impurities. This water will be passed through an activated carbon filter for removal of

organics. The filtered water from ACF is then chlorinated & stored in the flushing tank.

The attached growth fluidized aerobic bed reactor (FAB) process combines the biological

processes of attached & suspended growth. It combines submerged fixed film with extended

aeration for treatment of the waste water.

The waste water after screening is collected in an equalization tank. The equalization tank is

required for preventing surges in flow & facilitating equalization of characteristics over the

entire quantity of effluent in a given time. A provision for pre-aeration is made in the

equalization tank in order to ensure mixing & to prevent the sewage from going septic. The equalized sewage is then pumped into the FAB reactor for biological processing. The water

enters the bottom of the reactor & flows up through the fixed film media which grossly enhances

the hydraulic retention time & provides a large surface area for growth of biological micro –

organisms. The FAB reactor is aerated by fine pore sub – surface diffusers which provide the

oxygen for organic removal. The synthetic media floats on the water & the air agitation ensures

good water to micro-organism contact.

The FAB treatment is an attached growth type biological treatment process where in, the

majority of biological activity takes place on the surface of the PVC media. Continuous aeration

ensures aerobic activity on the surface of the media. Micro – organisms attach themselves on the

media & grow into dense films of a viscous jelly like nature. Waste water passes over this film

with dissolved organics passing into the bio-film due to concentration gradients within the film.

Suspended particles & colloid may get retained on this sticky surface where they are



decomposed into soluble products. Oxygen from the aeration process in the waste water provides

oxygen for the aerobic reactions at the bio-film surface. Waste products from the metabolic

processes diffuse outward & get carried away by the waste water or air currents through the

voids of the media.

The aerated effluent passes into a tube deck settler for clarification. The theory of gravity tube

settler system is that the carrier fluid maintains laminar flow in the settling media at specified

maximum viscosity. These two parameters of a carrier fluid, flowing through a hydraulic

configuration, will determine the velocity gradients of the flow, the height of boundary layer at

the inclined surface and the residence time within the media.

The carrier fluid must be viscous Newtonian, exhibiting a Reynolds number of less than 1000

and preferably, a number under 400. The laminar flow, through the inclined tubes, will produce

velocity gradients sufficiently large to form an adequate boundary layer, where the velocity of

fluid approaches zero. Boundary layers are necessary in functioning tube settlers, to allow

suspended solids to separate from the viscous carrier fluid. Under gravitational forces, they will

settle to the hydraulic surface of the tube and subsequently from the clarifier media.

Since the tubes are inclined at 60 degrees, solids settled on the tubes are continually discharged

down. This downward rolling action increases particle contact and hence further agglomeration,

which increases the sludge settle ability. Studies show that these agglomerated sludge particles

can have a settling rate in excess of ten times the settling rate of the individual floc particles in

the influent. These heavy agglomerated masses quickly slide down the 60 degree inclined tube

and settle at the bottom of the tank.

At the bottom of the Tube deck, where the sludge leaves the Tube surface, the larger

agglomerated captures smaller particles in the upcoming stream. This solid contact phenomenon

greatly enhances the capture efficiency.

Stages of Treatment: The treatment process consists of the following stages:

• Equalization

• Bio- Degradation



• Clarification & Settling

• Filtration

8.0 RAIN WATER HARVESTING

The storm water disposal 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 has been calculated to provide 53



rainwater harvesting pits at selected locations, which will catch the maximum run-off from the

area.

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) Peak Hourly rainfall of 50 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 50 mm/hr. The shaft is having a 3 mm diameter including

weep hole, vent pipe and 2.75 m depth. Inside the shaft, a recharge well of 200 mm diameter is

constructed for recharging the available water to the deeper aquifer. The ground water level in

the area is 4-14 meters bgl. The bottom of the recharge structure will be kept 4 m above this

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

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 = 60,239.81 m2

Green Area = 51638.29 m2

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

= 340502.46 – (60239.81 + 51638.29)

= 228624.37m2

Runoff Load

Roof-top Area = 60239.81 × 0.05 × 0.8

= 2409.59 m3/hr

Green Area = 51638.29 × 0.05 × 0.1

= 258.19 m3/hr

Paved Area = 228624.37 × 0.05 × 0.7

= 8001.85 m3/hr

Total Runoff Load = 2409.59 + 258.19 + 8001.85 m3/hr

= 10669.63 m3/hr

Taking 15 minutes Retention Time, Total volume of storm water = 10,669.63/4

= 2667.40 m3

Taking the effective diameter and depth of a Recharge pit 4 m and 4 m respectively, Volume of a

single Recharge pit = π d2h/4 = 3.14 × 4 × 4 × 4 / 4 = 50.24 m3

Hence No. of pits required = 2667.40/50.24 = 53 Pits.

Total of 53 Rain Water Harvesting pits are being proposed for artificial rain water recharge

within the project premises.
