2 INTRODUCTION proposes an Amendment (expansion) for Kalpataru Solitaire located at Mumbai, Maharashtra. The project was earlier granted Environment Clearance by SEIAA, Maharashtra vide letter no. SEAC-2013/CR-100/TC-1 dated for Plot area admeasuring and total construction area 31, Now, MHADA has allotted additional FSI vide CO/MB/REE/NOC/F-591/1508/2015 dt Hence, proposal is amendment to EC issued vide no. SEAC-2013/CR-100/TC-1 dated There is decrease of 31 tenements as compared to EC issued on Additional B.U. Area is proposed to be utilized by increasing the floor plate. The Plot area of the project is 4, and construction area now proposed is 33, The project is comprised of One building of 2 wings- wing A & wing B with 3 basements + ground+16 residential floors The project is residential development having total 135 Nos. of tenements. Therefore, in view of the above, we seek an amendment in existing Environment Clearance of the proposed project..

The wastewater will be treated in an onsite STP of 90 KLD capacity. Approx. 75 KLD of treated effluent will be generated from the STP which will be reused within the project premises for flushing and horticulture. Surplus treated effluent will be discharged to external sewer/used for nearby construction activities. SEWAGE TREATMENT TECHNOLOGY Aerobic attached growth process is an increasingly popular technology that improves the performance & efficiency of sewage treatment systems. The system consists of microbial activity in suspended phase, as is in the conventiona al activated sludge systems. In this system the same takes place in the attached phase in addition to the suspended phase. The attached growth phase is maintained through the media submerged in the reactor which provides high specificc surface area of media. 55

7 The media increases the microbial mass in the biological reactor which in turn accelerates removal rate of soluble contaminants and provide additional design capacity relative to conventional systems in the same design volume. a.

9 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 buildings/shall be connected to adjacent drain by our network through catch basins. 1. Since the existing topography is congenial to surface disposal, our storm water network is planned adjacent to roads. All building roof water will be brought down through rain water pipes. 2. Proposed storm water network consists of drains, catch basins and seepage pits at regular intervals for rain water harvesting and ground water recharging. The recharge pits of adequate size with desilting chamber will be constructed for recharging the ground water. 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 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. Provision of 4 Rain water Harvesting pits has been proposed for artificial ground water recharge. 58

Power back-up/dg sets (kva) SOLID WASTE GENERATION Proposed modification Total x 600 nil 1 x 600 = 600 Solid waste would be generated both during the construction as well as 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. 60

12 The excavated material and useful reusable material will be stacked for reuse. Since this is an Amendment (expansion) project, no top soil is available for reuse. The excavated/demolished material shall be utilized for refilling / road work / rising of site level at locations/ selling to outside agency for construction of roads etc. S. No. During the operation phase, waste will comprise of domestic and horticultural waste. The solid waste generated from the project shall be approx. 367 kg per day 0.5 kg per capita per day for 0.15 kg per capita per day for the visitor, 0.25 kg per capita per day for the staff 0.25 kg per capita per day for the fitness center). Following arrangements will be made at the site in accordance to Municipal Solid Wastes (Management and Handling) Rules, Description Table 9: Calculation of Solid Waste Generation Occupancy Nos. kg/capita/day Bio Degradable / day Non Biodegradable Kg/ day Waste generated (kg/day) 1 Resident Visitors Staff Fitness Center TOTAL SOLID WASTE GENERATED Collection and Segregation of waste: A door to door collection system will be provided for collection of domestic waste from household units. The occupants shall be educated to segregate the waste in separate colored bins for Bio-degradable and Non Bio-Degradable waste. For waste collection, adequate number of colored bins (for Bio-degradable and Non Bio-degradable) are proposed to be provided at the strategic locations of the area. Treatment of waste: Bio-Degradable waste 61

13 Bio-degradable waste will be subjected to composting by the use of organic waste converter and the compost will be used as manure. STP sludge is proposed to be used for horticultural purposes as manure. Recyclable waste The customers shall be educated to process recyclable wastes like paper, plastic, metals etc. for recycling. Disposal: Recyclable and non-recyclable wastes will be disposed through local approved agency. Solid waste management Scheme is depicted in the following figure. Figure 5: Solid Waste Management Scheme (Operation Phase) Organic Waste Converter An organic waste converter is a self-contained system capable of decomposition of biodegradable waste and producing organic manure as an output which can be put to horticultural use Benefits of organic waste converter: 62

14 CTS No. 25A/3 of village Vile Parle (W) of J.V.P.D schemee of Vile Parle (W), Large quantity of solid waste is converted to manure in a very short period. Manure can be sold as compost to farmers, or used for gardening. Machine requires less space and the efficiency is high. Manpower and maintenance is very less. This is one of the latest techniques of managing solid waste. Figure 6: Illustrative image of Organic Waste Convertorr GREEN AREA Total green area measures m 2 (20%) which will include area under tree plantation and lawn. Evergreen tall and ornamental trees have been proposed to be planted inside the premises. No. of trees required as per MoEFCC 1 tree/80 sqm = /800 = 51 No. of trees proposed to be planted = 56 63
