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 Auditorium = 14,000 litres Club Bldg. = 5000 litres Sub-stations = 2000 litres Site Office = 2000 litres (Above requirements has been worked out based on Non-Residential Building requirement @ 45 litres per capita per day, 10% floating population, and assuming occupancy @ 10 sq. meter per person). Total Water Requirements for Academic Complex = 129 m 3 /day ii) Wastewater Generation Assuming 80% of this coming out as waste water, Quantity of waste water generated from the Academic Complex is estimated to be about 103 m 3 /day. • Water Requirement for Residential Complex: i) Break Up of daily water consumption Chairman’s Residence (G+1) Director’s Residence (G+1, 2 nos.) Staff housing (36 nos., G+9) 36x5x200 Guest House (G+ 3, 24 suits) 24x1.5x200 Hostel for J. Academy (B+G+4) 80X200 Hostel for Boys (G+6, 200 Person) 200x200 Hostel for Girls (G+6, 200 Person) 200x200 Essential Staff Quarters (S+3, 12 nos.) 12x5x200 = 2000 litres = 4000 litres = 36,000 litres = 7200 litres = 16,000 litres = 40,000 litres = 40,000 litres = 12,000 litres Total Water Requirements for Residential Complex = 157 m 3 /day Considering 20% of daily water consumption as recycled water for toilet flushing, the total potable water requirement for drinking and other purposes = 126 m 3 /day Quantity of treated water used for flushing purpose = 31 m 3 /day ii) Wastewater Generation Assuming 80% of daily potable water consumption coming out as waste water, Wastewater Quantity = 101 m 3 /day 42

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 Total Wastewater Quantity from the Residential Complex = 101 + 31 = 132 m 3 /day Total Average Wastewater flow from both Academic and Residential Complex is estimated to be about = 103 + 132 = 235 m 3 /day Hence it is proposed to set up a Sewage Treatment Plant of capacity 250 m 3 /day. • AC Make Up Water Requirement: The make up water requirements for the air conditioning plant will be about = 42 m 3 /day Figure 3.0 gives the water balance diagram of the proposed project during the operation phase. 3.4 Building Design Features on Seismic Load Various measures taken to make the proposed building structure earthquake resistance include: • Building designed as a RCC framed structure. • The design of frame structures is based on stipulation of I.S. codes of earthquake design (I.S. 1893) • Ductility provisions to improve earthquake resistivity, as per the Indian Standards requirement also being incorporated. As such the structure is designed for earthquake resistivity taking into account latest provisions of Indian Standars codes for earthquake resistivity. 3.5 Resource and Construction Material Requirements Construction of the project components will require the use of renewable and non-renewable resources including wood, gravel, sand, steel, concrete, cement, bricks and paper products. The materials, apart from paper products, will be used during the construction period only and will not be required during the operation phase of the project. Paper products (e.g., paper, cardboard) will be used during the operation for record keeping, general commercial use etc. However, their use will be minimized. The estimated quantities of construction materials required are given in Table 3.4. During the construction activity, it is expected that no fill materials will be transported from outside. The total quantity of earthwork involved is estimated to be about 91,000 m 3 . 43
