Water Resources


Rainwater Harvesting:

       Rainwater harvesting may be defined as process of augmenting the natural infiltration of rainwater or surface run off into the ground by some artificial methods. The methods suggested are recharge through pits, trenches, bore well shafts by directly diverting run off water into existing or disused wells or conserving the rain water by artificial storing and using the same for human use. The choice and effectiveness of any particular method is governed by local hydrological and soil conditions and ultimate use of water.

Need for Rainwater Harvesting:

        Nature replenishes the ground water resources annually through rainfall; by way of infiltration though soil layers. In urban areas, due to urbanization, the soil surface exposed to natural recharge gets reduced. Therefore, natural recharge is diminishing, resulting in drying of wells. Groundwater source has the 196 benefit of availability where water is needed and during emergencies and scarcity period, the public at large or NGOs should take measures to improve the groundwater recharge by rain water harvesting to maintain reliable and sustainable groundwater resources
