Rapid Environmental Impact Assessment (REIA) Study for Proposed Integrated Complex for Delhi Judicial Academy, National Law School, and National Institute for Mediation & Conciliation at Dwarka, New Delhi 3.1.5 Back Up Power Supply System It is proposed to install four D.G. sets of 1000 KVA and one D.G. set of 500 KVA for full power back up in the academic complex. No DG set will be provided in the residential complex. However, certain essential services in it will be linked with the DG sets in the academic complex. The ventilating stacks of adequate height above the roof of the building will be provided as per the norms. Each DG set will also be equipped with state-of-the-art insulating and acoustic enclosures. 3.1.6 Fuel Requirements Diesel / Industrial Oil will be consumed for Diesel Generators in case of Power failure. The Diesel and Oil if required to be stored on the site as a reserved stock, will be stored in a drum / tin with proper identification mark / labels in identified area. Fire and safety measures will be taken as per the guidelines from the concerned authority. 3.1.7 Water Storage Tanks and Pump Room The project will provide two underground water storage tanks of capacities 250 m 3 and 225 m 3 in the academic and residential complex respectively. Additional overhead water storage tanks will also be provided in different blocks of the complex. Capacities of these tanks will be: In Academic Complex • Academic Block - 43,200 litres • Administration and Management Block - 50,000 litres • Auditorium and Cafeteria - 34,000 litres • Club Building - 25,000 litres In Residential Complex • Chairman’s Residence - 2000 litres • Director’s Residence - 4000 litres • Staff Housing - 41,200 litres • Guest House - 25,000 litres • Hostel for Judicial Academy - 27,000 litres • Boy’s Hostel - 38,000 litres • Girl’s Hostel - 38,000 litres • Essential Staff Housing - 5400 litres 36

Rapid Environmental Impact Assessment (REIA) Study for Proposed Integrated Complex for Delhi Judicial Academy, National Law School, and National Institute for Mediation & Conciliation at Dwarka, New Delhi A substantial portion of the basement will be utilized for the pump room. It is estimated about 60% of the water requirement will be met through piped water supply from DJB and the remaining from ground water. 3.1.8 Sewage Collection, Treatment and Disposal System It is proposed to establish one STP of 250 m 3 /day capacity in the complex based on aerobic Fluidized Bed Reactor Technology. The wastewater generated will be treated up to tertiary level. The single STP will serve both the academic and residential complex. The wastewater will be collected through a network of drainage system to be designed accordingly keeping in view the location of the STP. The treated effluent will be mostly reused for flushing of toilets in the residential complex and for gardening. Dual plumbing system will be provided for utilizing treated water for flushing of toilets. Unutilized treated effluent shall be discharged into the municipal sewerage network which is available around the proposed site. Reuse of treated effluent within the complex will reduce the overall requirement of fresh water as well as put less load on the existing sewerage network. During the project construction phase, the major source of water pollution will be sewage from labour camps and makeshift office. It is expected that at any given time during the construction phase, the peak manpower strength on construction site comprising of technical staff, clerical/supervisor, skilled and unskilled workers would be about 500 persons. The average domestic water requirements would be about 50 lpcd. Thus, total water requirements work out to be 25,000 litres / day (max.). It is assumed that about 80% of the water required will be generated as sewage. Thus, total quantum of sewage generated in peak situation is expected to be about 20,000 litres / day. The generated sewage would pass through a septic tank and its discharge would be connected to the existing municipal sewage network of the area. 3.1.9 Storm Water Drainage System All along the road storm water drains would be provided to collect water during rains. They would be adequately sized to prevent over flooding of the site. The storm water collection system will be designed in such a manner so that clean storm water from garden, parking areas, roadways and lawns is used for recharging of ground water. The excess run off will be directed towards the nearest storm water drain. 37
