Jamia Hamdard University

Rainwater Harvesting Potential
Catchment area – 3,15,280 square metres (sq. m)
Average annual rainfall in New Delhi – 611.8 millimetre (mm)
Total water available from rainfall – 67,444 cubic metre (m3) or 6,74,44,000 litres

Rainwater Harvesting System
Storm water, surface runoff and road runoff from the campus along with runoff from the adjoining Jahanpanah Forest ridge area is being harvested in the University with the helpp of variety of rainwater harvesting structures spread all over the campus. A part of the harvested water is stored in water bodies at the upstream of recharge structures.

There are 12 recharge chambers with recharge tubewells where the surface runoff is filtered by a separate desilting tank having a settlement chamber and a filtering tank. After filtration it passes to the recharge well having a recharge bore of 30 metre depth. The harvested water is filtered using the layers of boulders, pebbles and garvels before it is recharged to the sub soil.

The runoff from the road is collected in a trench, filtered and then diverted to the abandoned open well while the surface runoff from the reserve forest is collected in a pond, which also has a desilting machanism.

The rainwater harvesting structure was completed in the year 2001 at a cost of Rs.15 lakh.

Impact: There has been an improvement in the yield of the tubewells and a gradual improvement in the quality of groundwater. The water level rose by 8 metres in the year 2003.

Viswa Ahimsa Sangh

Rainwater Harvesting Potential
Catchment area – 4050 square metres (sq. m)
Average annual rainfall in New Delhi – 611.8 millimetre (mm)
Total water available from rainfall – 1,637 cubic metre (m3) or 16,37,000 litres

Rainwater Harvesting System
The runoff harvested from the campus is used to recharge the sub soil using three recharge wells with filtration chambers. The sizes of the recharge wells are 2 m x 2 m x 2 m, 1.5 m x 1.5 m x 1.5 m and 2 m x 1.5 m x 2 m with 25 metre deep recharge bores each. The harvested water is filtered using the layers of boulders, pebbles and gravel before it is recharged to the sub soil.

The rainwater harvesting structure was completed in the year 2005 at a cost of Rs 1.95 lakh.

Impact: There has been an improvement in the yield of tubewell and the groundwater quality.

Sri Aurobindo Ashram and The Mother International School

Rainwater Harvesting Potential
Catchment area – 95,870 square metres (sq. m)
Average annual rainfall in New Delhi – 611.8 millimetre (mm)
Total water available from rainfall – 16,366 cubic metre (m3) or 1,63,66,000 litres

Rainwater Harvesting System

The runoff from the rooftop, paved playground and storm water drains is harvested using 11 recharge wells with recharge tubewells, 3 abandoned wells and 5 recharge pits with shallow bores. The harvested water is filtered using the layers of boulders, pebbles and coarse sand before recharging.

The rainwater harvesting structure was completed in the year 2003 at a cost of Rs. 15 lakh.

Impact: There has been an improvement in the yield of tubewell and groundwater quality.

The Shri Ram School

Rainwater Harvesting Potential
Catchment area – 6,000 square metres (sq. m)
Average annual rainfall in New Delhi – 611.8 millimetre (mm)
Total water available from rainfall – 1,784 cubic metre (m3) or 17,84,000 litres


Rainwater Harvesting System
Rooftop rainwater outlets are interconnected through a network of pipes and collection chambers which lead to a filtration-cum-buffer tank of 21,250 litres. The overflow from the tank is diverted to a borewell of 200mm diameter and 30m depth to facilitate recharging of the underground aquifer. The harvested water is filtered using the layers of boulders, pebbles and coarse sand before it is recharged to the sub soil.

The rainwater harvesting structure was completed in the year 2000 at a cost of Rs 1.25 lakh.

Impact: There has been an improvement in the yield of tubewell and the groundwater quality. The groundwater level rose in the year 2003 but has been falling since. However, the rate of decline of grounwater table is lower than the average rate of decline of grounwater table in the surrounding area.

Janki Devi Memorial College

Rainwater Harvesting Potential
Catchment area – 32,170 square metres (sq. m)
Average annual rainfall in New Delhi – 611.8 millimetre (mm)
Total water available from rainfall – 6,500 cubic metre (m3) or 65,00,000 litres

Rainwater Harvesting System
The runoff from the rooftop is harvested using three wells provided with recharge bores of 150 mm diameter and 15 metre depth. Each recharge well measures 2 m x 2 m x 2 m. The runoff from the unpaved area is intercepted at the main gate by a collection trench and from here the runoff eventually drains into an abandoned open well, which facilitates groundwater recharge.

The rainwater harvesting structure was completed in the year 2001 at a cost of Rs 70,000.

Impact: There has been an improvement in the water levels and the groundwater quality.
