DELHI GYMKHANA CLUB’S RAINWATER HARVESTING SYSTEM

RAINWATER AVAILABLE FOR HARVESTING
Total rooftop and surface area: 1,13,344 square metres (sq m)

Average annual rainfall in Delhi: 611 millimetres (mm)
Total volume of rainwater harvested: 28,765.8 cubic metres (m 3 ) or
2,87,65,849.4 litres
Therefore, 43 per cent of total rooftop and surface runoff is being harvested.

WATER SUPPLY SOURCE
Five tube wells located in the premises coupled with municipal supply. On an
average, 4 lakh litres of water is consumed daily for potable and non-potable
purposes.

RAINWATER HARVESTING SYSTEM
The rooftop rainwater from the main club building, library, committee room,
secretary office and cottages is flown down to the ground and then taken to the
storm water drain. The storm water drains are intercepted at strategic locations
and rainwater is diverted into recharge wells. The recharge wells are 2.5 m x 2 m x 2 m in size. To facilitate groundwater recharge, a bore of 150 mm dia and 15 m depth is provided in all structures. Layers of boulders, pebbles and coarse sand filled inside the recharge well ensures proper filtration of harvested water.
Implementation of this project was completed in May 2004, and the groundwater level, as in January 2005, was around 14.1 m below ground level (bgl).

Cost of the rainwater harvesting system: Rs 0.8 lakh
