The wastewater will be treated in onsite STP of 515 KLD capacity. The treated effluent will be reused for flushing, horticulture & DG cooling. Surplus will be discharged to CSTP of Greater Noida Authority. SEWAGE TREATMENT PLANT SAFF TECHNOLOGY Sewerage System An external sewage network shall collect the sewage from all units, and flow by gravity to the proposed sewage treatment plant. M/s Trident Infra Homes Pvt. Ltd 8

10 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 32 o C (d) ph : (e) Colour : Mild (f) T.S.S. (mg/l) : mg/l (g) BOD 5 (mg/l) : mg/l (h) COD (mg/l) : 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 M/s Trident Infra Homes Pvt. Ltd 9

11 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.

12 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 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. M/s Trident Infra Homes Pvt. Ltd 11

13 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 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 = m 2 Green Area = 13, m 2 Paved Area = Total Plot Area (Roof-top Area + Green Area) = 30, ( , ) = 11, m 2 Run-off from green and paved area: Green Area = 13, = 58 m 3 /hr Paved Area = 11, = 397 m 3 /hr Total Run-off from green and paved area = = 455 m 3 /hr Taking 15 minutes retention time, total volume of storm water = 455/4 = 114 m 3 Taking the effective dia and depth of a Recharge pit 3 m and 4 m respectively, Volume of a single Recharge pit = π r 2 h = = 28 m 3 Hence no. of pits required = 114 / 28 = Pits = 4 pits 4 Rain Water Harvesting pits are proposed for artificial ground water recharge.
