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

proposed sewage treatment plant.

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.

Narela Sub City,

(d) Total Suspended Solids : <20mg/l

c. 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



Narela Sub City,

New Delhi


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

Figure 2: Schematic Diagram of STP

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 is 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. Taking the advantage of road

chambers, the rainfall run off from roads flows towards the drains. Storm water from various

flats/corridors is connected to adjacent drain by a pipe through catch basins. Therefore, 39 rain

water harvesting pits have been installed at selected location, which catches 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 adjacent to roads. All building roof water is brought down through rain water

pipes.

2) Existing storm water system consists of pipe drain, catch basins and Desilting

Chambers at regular intervals for rain water harvesting and ground water recharging.

3) For basement parking, the rainwater seeped through ramps is collected in the basement

sump. This water is pumped out to the nearest external storm water drain.

4) The peak hourly rainfall of 45 mm/hr has been 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 4 m diameter and 4 m

depth is constructed for recharging the water. The ground water level in the area is 60-65

meters bgl. The bottom of the recharge structure is kept 5 m above this level. At the bottom of

the recharge well, filter media is provided to avoid choking of the recharge well. Design

specifications of the rain water harvesting plan are as follows:

• Catchments/roofs is accessible for regular cleaning.

• The roof consists of 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.



Narela Sub City,

New Delhi


• All gutter ends are fitted with a wire mesh screen and a first flush device has been

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

paper pieces is 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 is admitted into the system.

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

the system.

Calculation for storm water load

Plot Area = 208302.85 sq.m.

Roof-top area = Ground Coverage = 43222.00 sq.m.

Green Area = 64573.8835 sq.m.

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

= 100506.97 sq.m.

Runoff Load:

Roof-top Area = 43222.00 x 0.045 x 0.9

= 1750.49 m3/hr

Green Area = 64573.8835 x 0.045 x 0.1

= 2905.82 m3/hr

Paved Area = 100506.97 x 0.045 x 0.7

= 3165.96 m3/hr

Total Runoff Load = (1750.49 + 2905.82 + 3165.96) m3/hr

= 7822.27 m3/hr

Taking 15 minutes Retention Time, Total volume of storm water = 7822.27/ 4

= 1955.5675 m3, say 1955.56 m

3

Taking the effective dia 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 Rain Water Harvesting pit required = 1955.5675 /50.24 = 38.92 say 39

However we propose to provide 39 nos of RWH pits for artificial ground water recharge.
