PANCHSHEEL PARK COLONY'S RAINWATER
HARVESTING SYSTEM
|
RAINWATER AVAILABLE FOR HARVESTING
Total rooftop and surface area 3,57,150 square metres (sq
m)
Average annual rainfall in Delhi 611 millimetres (mm)
Total volume of rainwater harvested: 1,74,575 cubic metre
(m³), or 174,575,000 litres
This represents 80 per cent of the total water harvesting
potential
WATER SUPPLY SOURCE
The water supply is mainly through six borewells. Three each
are owned by the Panchsheel Cooperative
Group Housing Society and the Delhi Jal Board respectively.
The remaining water requirements are met by individual borewells.
RAINWATER HARVESTING SYSTEM
Rooftop rainwater and surface runoff harvesting: A network
of stormwater drains in the entire residential area is used
for harvesting rooftop rainwater and surface runoff. About
36 Recharge wells measuring 1m x 1m x 2m are constructed in
the stormwater drain for facilitating groundwater recharge.
The quality of runoff, which passes through a 15m borewell
installed inside the recharge well, is ensured through a filter
bed of pebbles.
The project was implemented in June 2002. The cost of
the entire rainwater harvesting system was Rs 8 lakh.
IMPACT
The water level in the Panchsheel Park area, considered one
of Delhi's posh colonies, was declining rapidly. Keeping in
view the growing water problems, the Resident Welfare Association
established a rainwater harvesting system for the entire colony.
