To arrest the rapid decline of groundwater, the international donor agency, Ford
Foundation, New Delhi, has implemented the rainwater harvesting system in its Lodhi Road
office. CSE extended technical guidance.
Rainwater system at Ford
The Ford complex comprises of two buildings: the head
office and the guest house jointly covering an area of 12,500 square meters (sq m). To
harvest runoff from rooftop, paved (1,066 sq m) and unpaved (543 sq m) that earlier used
to flow through the gate to the road, four recharge trenches have been installed.
These trench cum percolation pits, measuring 0.5 meters (m)
x 2 m x 5 m, have been constructed near the gate. The trenches are covered with metal
gratings to facilitate vehicular movement. Within these trenches, three recharge borewells
with a diameter of 4 inches and a depth of 6 m have been built. The recharge well has a
filtering bed to check the entry of the suspended material into the groundwater reserves.
The works were completed last year at a total cost of Rs 4 lakh.
