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 The water table recharging pits of 24 meter overall depth will be constructed. They will have 3M x 3M x 3.65M deep clear inside chamber having 230 – 460 mm thick brick wall all around in cement mortar 1:4 (1 cement : 4 coarse sand), 760 mm wide x 200 mm deep PCC below brick work. The chamber shall be partially filled with stone ballast, coarse sand gravel and boulders as shown in Figure 7.1. Four nos. perforated 110 mm NB uPVC pipe 750 mm long one in each wall for taking the run off water into the recharging pit will be provided. The bottom pit portion shall have a dia of 350 mm, with a 200 NB slotted uPVC pipe of CS thick 23.5 M placed at center of pit having a GI perforated sheet cover at top for regulating the run off water to the bottom of the pit. The top cover shall be RC slab in 1:1.5:3 150 mm thick with reinforcement at top and bottom as per design with a precast RCC manhole cover MD -10 500 mm dia fixed in position. The storm water drains carrying the surface run off from the plot area will be directed towards these recharge pits. There will be a provision of sedimentation tanks where any silt or floating materials carried away by the flowing water will be settled down before the water enters the recharge area. Figure 7.2 gives the layout plan showing rain water harvesting pits in the proposed integrated complex. 7.7 Landscaping and Green Belt Development Plan It is proposed to develop landscape and green area in approx. 28.49% of total plot area in academic complex and approx. 24.91% of total plot area in residential complex. The implementation for development of green belt is of immense importance, as it not only acts as a pollution sink for dust emissions, gaseous pollutants and noise pollution but also enhances the visual appearance of the developed site. 129
