ANNULAR, CIRCULAR, SEGREGATED WATER HARVESTING

Way Forward:

Jn nurm – URBAN RAIN WATER HARVESTING

Tackle water shortage during summers

Recharge aquifers

Reduced power consumption in pumping water

Reduced water logging and flooding in low lying areas

Reduced erosion

Improved Groundwater quality through dilution
