High Capacity Recharge Pit Designed By Manohar Khushalani

This Ground Water Recharge Pit is for Societies with many flats or in institutional areas. Size is Indicative depending on the size of the catchment. More than one Pit can be used if necessary. Water to such a pit should be cleaned through one or more Desilting Tanks. See the previous article on Desilting tank

Important: The number of borewells depends on the volume of water. Minimum one, maximum two, Three borewells can be used only in exceptional circumstances. Under no circumstance, the borewell should be deeper than the first aquifer. This is to ensure that people dont use it for pumping out water from deep aquifers.

If there is only direct surface runoff to the harvesting pit from surrounding areas see the next article on built-in desilting weir
