SURYA VIHAR RAINWATER HARVESTING
SYSTEM
|
RAINWATER AVAILABLE FOR HARVESTING
Total rooftop and surface area:
44,029square metres (sq m)
Average annual rainfall in Gurgaon:
577.8 millimetres (mm)
Total volume of rainwater harvested:
18,207 cubic metres (m 3 ) or 1,82,07,031 litres
Therefore, 85 per cent of the total rooftop and surface runoff
is being harvested.
WATER SUPPLY SOURCE
The water requirement is fulfilled by four tubewells located
in the premises and supplemented by municipal supply.
Around 5.5 lakh litres of water is used for daily requirements.
RAINWATER HARVESTING SYSTEM
Rooftop rainwater harvesting: Rainwater from the Row Houses
and the Club building is flown into the storm drain that runs
parallel to the northern boundary wall. The rainwater from the
rooftops of B, C, D, E and G block along with the surface runoff
from the paved area is flown into the storm drain. This water
is harvested by constructing nine percolation pits within the
storm drain or diverting water to nearby recharge wells at strategic
locations. These pits are also provided with a recharge bore
of 150 mm diameter and 10 m depth to facilitate the recharging
of water into the subsoil strata.
Surface runoff harvesting: Surface runoff generated from the
roads along with rooftop rainwater from B, C and D block used
to cause water logging for hours unless pumped out near the
abandoned gate. This water is now recharged through 4.5 m long,
1 m wide and 2 m deep recharge trench at the gate. The trench
is provided with two recharge bores of 150 mm diameter and 18
m depth. Layers of pebbles and boulders inside the trench ensure
better filtration.
The implementation was completed in August 2002 and the groundwater
level, as in February 2004, was around 48.3 m below ground level
(bgl).
The total cost incurred: Rs 0.65 lakh
