GROUND WATER MEDIUM (Hydrogeological Conditions)
About 85% of the state is covered by Deccan basalts whereas the rest of the state is covered by Quaternary alluvium, Gondwanas, Cuddapahs, Kaladgis, Vindhyans, Dharwars and Archaeans. Based on the hydrogeological properties of different rock formations, the State can be divided into three major groups namely Unconsolidated, Semi-consolidated and Consolidated groups. The yield of dug wells in Deccan Trap varies from 0.2 to 30 m3/hr whereas in Vindhyans, Cuddapahs and Kaladgi, it varies from 1.12-10 m3/hr. In Archaean, yield is just 3-4 m3/hr. In the semi consolidated formations, which consists of coastal Sedimentaries, Intra-trapeans and Gondwanas, the dugwells yield between 6-12m3/hr. In unconsolidated formations, the dugwells yield between 0.5-20m3/hr.

Enactment of Ground Water Bill to regulate and control the development of ground water:
Maharashtra Ground Water (Regulation for Drinking Water Source) Act, 1993 was enacted on 16.8.1993 for the limited purposes of regulating the exploitation of ground water for the protection of public drinking water sources in the State. Maharashtra Ground Water Regulation Act has also been drafted and being laid on the Table of House.
Inclusion of Roof Top Rain Water Harvesting (RTRWH) in building by laws:
Maharashtra Government is promoting roof top rainwater harvesting under the “ Shivkalin Pani Sthawan Yojana” It provides that all the houses should have provision for rain water harvesting .
Bombay Municipal Corporation and Pimpri-Chinchwad Municipal Corporation: Rain Water Harvesting has been made mandatory by enacting building bylaws.
