Rapid Environmental Impact Assessment (REIA) Study <strong>for</strong> Proposed Integrated Complex <strong>for</strong> Delhi Judicial Academy,<br />

National Law School, and National Institute <strong>for</strong> Mediation & Conciliation at Dwarka, New Delhi<br />

A substantial portion of the basement will be utilized <strong>for</strong> the pump room. It is estimated about<br />

60% of the water requirement will be met through piped water supply from DJB and the<br />

remaining from ground water.<br />

3.1.8 Sewage Collection, Treatment and Disposal System<br />

It is <strong>proposed</strong> to establish one STP of 250 m 3 /day capacity in the <strong>complex</strong> based on aerobic<br />

Fluidized Bed Reactor Technology. The wastewater generated will be treated up to tertiary level.<br />

The single STP will serve both the academic and residential <strong>complex</strong>. The wastewater will be<br />

collected through a network of drainage system to be designed accordingly keeping in view the<br />

location of the STP. The treated effluent will be mostly reused <strong>for</strong> flushing of toilets in the<br />

residential <strong>complex</strong> and <strong>for</strong> gardening. Dual plumbing system will be provided <strong>for</strong> utilizing<br />

treated water <strong>for</strong> flushing of toilets. Unutilized treated effluent shall be discharged into the<br />

municipal sewerage network which is available around the <strong>proposed</strong> site. Reuse of treated<br />

effluent within the <strong>complex</strong> will reduce the overall requirement of fresh water as well as put less<br />

load on the existing sewerage network.<br />

During the project construction phase, the major source of water pollution will be sewage from<br />

labour camps and makeshift office. It is expected that at any given time during the construction<br />

phase, the peak manpower strength on construction site comprising of technical staff,<br />

clerical/supervisor, skilled and unskilled workers would be about 500 persons. The average<br />

domestic water requirements would be about 50 lpcd. Thus, total water requirements work out to<br />

be 25,000 litres / day (max.). It is assumed that about 80% of the water required will be<br />

generated as sewage. Thus, total quantum of sewage generated in peak situation is expected to be<br />

about 20,000 litres / day. The generated sewage would pass through a septic tank and its<br />

discharge would be connected to the existing municipal sewage network of the area.<br />

3.1.9 Storm Water Drainage System<br />

All along the road storm water drains would be provided to collect water during rains. They<br />

would be adequately sized to prevent over flooding of the site. The storm water collection system<br />

will be designed in such a manner so that clean storm water from garden, parking areas,<br />

roadways and lawns is used <strong>for</strong> recharging of ground water. The excess run off will be directed<br />

towards the nearest storm water drain.<br />
