In populated metropolitan cities, the primary sources of water include groundwater and lakes. Groundwater is harvested with the help of borewells whereas pipes harvest water directly from the lakes. The harvested water is then stored in water tankers placed at strategic locations throughout the city.
Many of us live in cities, where water is supplied by the municipal authorities. In the houses, systems of rainwater harvesting are installed which collect the water running off and channel it into a special pit created for the purpose. This helps to recharge ground water.
Efforts are being made to collect run off rain water in soak pits. This water enriches underground water and can cause rise in water table.
Run off water from roof tops can also be collected in trenches, specially made to enrich underground water table.
Traditional techniques of water harvesting are nearly location specific.
For eg. khadins, tanks and nadis in Rajasthan.
Bandharas and tals in Maharashtra.
Ahars and Pynes in Bihar.
Kulhs in Himachal Pradesh.
Ponds in Jammu.
