Rainwater Harvesting Potential
Catchment area – 300 square metres (sq. m)
Average annual rainfall in Guwahati – 1,600 millimetre (mm)
Total water available from rainfall – 400.65 cubic metre (m3) or 4,00,650 litres

Rainwater Harvesting System
The rainwater harvested from the catchment of 300 sq. m is collected in two storage tanks of total capacity 5,000 litres. The stored water is used for horticulture. Rainwater harvesting has reduced the groundwater extraction to 400 litres per day.

Impact:Rainwater harvesting has lead to a reduction in groundwater extraction.

Total water available from rainfall – 133.55 cubic metre (m3) or 1,33,500 litres

Rainwater Harvesting System
The rainwater harvesting system comprises of a combination of recharge and storage structures. Runoff from the rooftop is stored in a concrete storage tank. The stored water is used for drinking purpose. A part of the harvested water is diverted to an active well to recharge the sub soil.

The rainwater harvesting structure was completed at a cost of Rs 3,500.

Impact: Rainwater harvesting has lead to improvement in groundwater quality and water level in the well has increased by one metre approximately.
