40 ANNEXURE: B SOURCE OF WATER FOR THE PROPOSED PROJECT: The most important aspect under the water supply scheme is the selection of source of Water, which should be reliable and potable. The source of water supply to the proposed project is through Mandur Gram Panchayath Sources. DETAILS OF WATER CONSUMPTION OF THE PROJECT: The apartment being a residential one, water demand is for domestic purpose, public uses and fire fighting purposes. It includes the quantity of water required in the houses for drinking, bathing, cooking, washing etc., The quantity of water required for domestic purposes depends on the habits, social status, climatic conditions and customs of the people. In India on an average the domestic water consumption under normal conditions is about 135 litres/capita/day as per National Building Code (NBC), the details of domestic consumption is as follows Sl.

WATER DISTRIBUTION SYSTEM: The proposed water supply scheme to cater to the public and domestic water requirement of the proposed project consists of sourcing potable water to a common collection facility known as the Raw Water Sump. The Raw Water Sump will be constructed in RCC. The water from the UG sump will be pumped to overhead tank. The OHTs will be staged on terrace depending on the contour of its distribution network. 69 PROJECT REPORT

42 ANNEXURE: C 1. SEWAGE GENERATION AND DISPOSAL SYSTEM: Wastes of different type such as spent water from bath rooms, water closets/pans, house and street washings, semi liquid waste of human excreta, dry refuse of house and street sweepings, broken furniture, crockery etc., are produced daily. If proper arrangement for collection treatment and disposal of all the wastes produced are not made, unsanitary conditions will develop and it will become impossible for the public to live. Therefore, it is most essential to collect, treat and dispose all the sanitary waste produced. Generally, it has been observed that about % of the water supplied comes out as sewage. Therefore, the total quantity of wastewater generated from the proposed Project is worked out as below. Sl.

Other construction projects/ watering avenue plantations = 471 KLD DESIGN DETAILS OF STP AND TREATMENT METHODOLOGY ADOPTED: In the project Two Sewage Treatment Plants (STP) of capacity 650 and 500 KLD are proposed to treat the wastewater generated from the project. The 650 KLS STP will be established as per the techicnial details submitted during obtaining EC for the project. Design details of 500 KLD STP is presented below: Treated water specifications as per KSPCB standards: Treated Sewage Standards: Treated Sewage ph : 6-9 Treated Sewage BOD 5 : <10 mg/l Turbidity (NTU) : <2 E.

44 TECHNOLOGY BRIEF OF TREATMENT PROPOSED: The Sequencing batch reactor (SBR) process is a sequential suspended growth (activated sludge) process in which all major steps occur in the same tank in sequential order (figure 1). There are two major classifications of SBRs: the intermittent flow (IF) or true batch reactor, which employees all the steps in figure 1, and the continuous flow (CF) system, which does not follow these steps. Both have been used successfully worldwide installations. SBRs can be designed and operated to enhance removal of nitrogen, phosphorus, and ammonia, in addition to removing TSS and BOD. The intermittent flow SBR accepts influent only at specified intervals and, in general, follows the five-step sequence. There are usually two IF units in parallel. Because this system is closed to influent flow during the treatment cycle, two units may be operated in parallel, with one unit open for intake while the other runs through the remainder of the cycles. In the continuous inflow SBR, influent flows continuously during all phases of the treatment cycle. To reduce short circuiting, a partition is normally added to the tank to separate the turbulent aeration zone from the quiescent area. 72 PROJECT REPORT
