5 Figure 1: Water Balance Diagram Waste water Generation & Treatment It is expected that the project will generate approx KLD of waste water. The waste water will be treated by an onsite STP. Treated water will be brought through private water tankers and will be used for flushing and horticulture purpose. 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. 7. RAIN WATER HARVESTING SYSTEM 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 M/s Ajnara India Ltd. 38

6 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 areas/shall be connected to adjacent drain by a pipe through catch basins. Therefore, it has been calculated to provide 44 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. Rain water harvesting has been catered to and designed as per the guideline of CGWB. Peak hourly rainfall has been considered as 0.45 m/hr. The recharge pit of diameter of 4 m and 3 m depth is constructed for recharging the water. During pre monsoon season the ground water level is 3.35 to mbgl and as on post monsoon season the ground water level is 2 to mbgl. 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 minutes of rainfall is flushed off. No sewage or waste water would be admitted into the system. No waste water from areas likely to have oil, grease, or other pollutants has been connected to the system. M/s Ajnara India Ltd. 39

The DG sets will be equipped with acoustic enclosure to minimize noise generation and adequate stack height for proper dispersion. 10. SOLID WASTE GENERATION Solid waste would be generated both during the construction as well as during the operation phase. The solid waste expected to be generated during the construction phase will comprise of excavated materials, used bags, bricks, concrete, MS rods, tiles, wood etc. The following steps are proposed to be followed for the management solid waste: Construction yards are proposed for storage of construction materials. The excavated material such as topsoil and stones will be stacked for reuse during later stages of construction. Excavated top soil will be stored in temporary constructed soil bank and will be reused for landscaping of the group housing project. Remaining soil shall be utilized for refilling /road work / rising of site level at locations/ selling to outside agency for construction of roads etc. M/s Ajnara India Ltd. 41

The total solid waste generated from the project shall be mainly domestic waste and estimated quantity of the waste shall be approx kg per day 0.45 kg per capita per day for 0.25 kg per capita per day for Staff per day for Visitors.

It will be handed over to Govt. approved vendors. Collection and Segregation of waste 1. A door to door collection system will be provided for collection of domestic waste in colored bins from household units. 2. The local vendors will be hired to provide separate colored bins for dry recyclables and Bio-Degradable waste. 3. For waste collection, adequate number of colored bins (Green and Blue & dark grey bins separate for Bio-degradable and Non Bio-degradable) are proposed to be provided at the strategic locations of the area. 4. Litter bin will also be provided in open areas like parks etc. Treatment of waste Bio-Degradable wastes 1. Bio-degradable waste will be subjected to Organic Waste Converter and 20% of the subjected waste will be used as manure. 2. STP sludge is proposed to be used for horticultural purposes as manure. 3. Horticultural Waste is proposed to be composted and will be used for gardening purposes. Recyclable wastes i. Grass Recycling The cropped grass will be spread on the green area. It will act as manure after decomposition. ii. Recyclable wastes like paper, plastic, metals etc. will be sold off to recyclables. M/s Ajnara India Ltd. 43

11 Disposal Recyclable and non-recyclable wastes will be disposed through Govt. approved agency. Hence, the Municipal Solid Waste Management will be conducted as per the guidelines of Municipal Solid Wastes (Management and Handling) Rules, A Solid waste management Scheme is depicted in the following figure for the Group Housing Project. Figure 3: Solid Waste Management Scheme (Operation Phase) Benefits of Organic waste converter: Aerobic microbial decomposition into compost Biomechanical process produces Odour free output in 15 minutes Compost manure generated can be used for soil conditioning Prevents production of methane gas. 11. GREEN AREA Area which will be area under landscaping and tree plantation within the residential plots and along the roads. Ornamental tress like Jacaranda and Gulmohar has been proposed to be planted inside the premises. Parks will also be developed by the management. M/s Ajnara India Ltd. 44
