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 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

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.

ANNEXURE-4: PROPOSED RAIN WATER HARVESTING STRUCTURES / RECHARGING STRUCTURES

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 blocks shall be connected to adjacent drain by a pipe through catch basins. The water table becomes more than 25 m in future, rainwater harvesting can be carried out. Therefore, it has been calculated to provide 4 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) 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) Annual rainfall of 731mm/yr shall be considered for designing the storm water drainage

system. Peak hourly rainfall has been considered as 25 mm/hr. The recharge pit of 2.5mx5mx4m is constructed for recharging the water. Inside the recharge pit, a recharge bore is constructed having 300 mm diameter and 30 m depth. The bottom of the recharge structure will be kept 4 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 = 418512.01 m2

ANNEXURE-4: PROPOSED RAIN WATER HARVESTING STRUCTURES / RECHARGING STRUCTURES

Green Area = 33980.17 m2 Paved Area = Total Plot Area – (Roof-top Area + Green Area)

= 491603.25– (418512.01 + 33980.17) = 39111.07m2 Runoff Load Roof-top Area = 418512.01 × 0.025 × 0.95 = 9939.66 m3/hr Green Area = 33980.17 × 0.025 × 0.1 = 84.95 m3/hr Paved Area = 39111.07 × 0.025 × 0.75 = 733.33 m3/hr Total Runoff Load = ( 9939.66 + 84.95 + 733.33 ) m3/hr = 10757.94 m3/hr Taking 15 minutes Retention Time, Total volume of storm water = 10757.94 /4 = 2689.48 m3 Taking the effective size of a Recharge pit 2.5mx5mx4m respectively, Volume of a single Recharge pit = L x B x H = 2.5 x 5 x 4 = 50 m3 Hence No. of pits required = 2689.48/50 = 53.78 or say 54 Pits.
