Irrigation Water: Irrigation water for landscape use shall be sourced from the in-house STP and shall have acceptable parameters as per KSPCB standards SEWAGE TREATMENT PLANT It is proposed to provide sewage treatment plants of 160 KLD capacities for treatment of sewage water. The treated effluent shall be of a quality suitable for domestic use, flushing and for horticulture for external areas. Following parameters shall be adopted for the design of sewage treatment plant. Parameters for design of sewage treatment plant Parameters V a l u e Before Treatment After Treatment ph BOD Mg/L Less than 10 Mg/L Suspended Solids Mg/L Less than 20 Mg/L COD Mg/L Less than50 Mg/L Fecal coliform MPN/100 NIL PROCESS DESCRIPTION In order to conserve water, sewage treatment plant shall be designed to ensure that treated effluent (water) characteristics are well below the permissible limits, even under varying flow conditions which are typical for such systems. This implies that the selected process shall be able to withstand shock load situations. The sewage water is treated in Membrane filtration in MBR technology and reused for domestic purposes, Flushing and for external horticulture. The detailed STP report is enclosed as Annexure-V 2.9. Preventive measures to avoid leaching of treated sewage into nearby water courses Treated water from Sewage Treatment Plants will be conveyed to Treated water Tank through pipelines. All the joints from piping system will be checked periodically and carrying 45

14 treated wastewater pipes will be laid in conduits wherever road crossings are expected. Garland drains will be constructed all around the Development for intercepting water from outside and inside. Thus no leaching of treated sewage into nearby water courses shall take place. 2.1 Solid Waste Generation, Collection, Transport and Disposal The quantity of solid waste generated from the proposed project is estimated to be 498Kg/day. Waste generated by users- Domestic wastes food left over s, vegetable peels, plastic, house sweepings, clothes, ash, etc. commercial waste generally comprises of paper, cardboard, plastic, wastes like batteries, bulbs, tube lights etc. Colored bin system for different categories of waste is a good option for segregation at household level. Storage facilities will be created and established by taking into account quantities of waste generation in a given area and the population densities. The estimation of solid waste generation for Residential houses is taken as 0.4 kg/person/day. Solid waste generated in total is about 498 kg/day. Table 2.7 details the calculation of total solid waste generated. The organic waste is 299/day; inorganic waste is 199 Kg/day. STP sludge of about 16kg/day would be filter pressed and used as manure for greenbelt development. Solid waste are collected from individual houses are segregated in to organic & inorganic waste, organic waste is converted into manure using organic converter & used for the development of greenery & inorganic waste will be sent for recycling.
