Sullage Generation & Treatment It is expected that the project after modification will generate approx. 1213 KLD of sullage. The sullage will be treated in 3 onsite STPs of 600 KLD, 720 KLD and 230 KLD capacity that will generate 1092 KLD of treated water from STP which will be reused for flushing, horticulture.

SEWAGE TREATMENT TECHNOLOGY

EXTENDED AERATION TECHNOLOGY Sewerage System An external sewage network shall collect the sewage from all units, and flow by gravity to the proposed sewage treatment plant.

Following are the benefits of providing Sewage Treatment Plant:  Reduced net daily water requirements, source for Horticultural purposes by utilization of the treated sullage.  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 purpose.

Treatment Technology Treatment technology is based on the Extended Aeration Technology. 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 sullage. 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

101 M/s Chintel India Pvt. Ltd. Modification of Group Housing Project, Village Babupur, Sector -108, Gurgaon, Haryana CONCEPTUAL PLAN after treatment will be stored in a sump of desired capacity. Treated effluent coming out from the sump will be passed through softening plant followed with disinfection.

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. 134 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 sumps. This water will be pumped out to the nearest external storm water drain. 4) The peak hourly rainfall of 21.3 mm/day 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 21.3 mm/day. The recharge pit of 1.2 m diameter and 3.0 m depth is constructed for recharging the water. The ground water level in the area is 30-40 meters bgl. The bottom of the recharge structure will be kept 4m 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.  No sewage or wastewater would be admitted into the system.

104 M/s Chintel India Pvt. Ltd. Modification of Group Housing Project, Village Babupur, Sector -108, Gurgaon, Haryana CONCEPTUAL PLAN

 No wastewater from areas likely to have oil, grease, or other pollutants has been connected to the system. Rain water harvesting pits comparative details are given below in Table 7.
