Hydrogeology
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 dug wells yield between 0.5-20m3/hr.

Enactment of Ground Water Bill to regulate and control the development of ground water:
Maharashtra Water Resources Regulatory Authority Act was enacted in May 2005 and the State Govt. is considering amending this Act to incorporate the provision included in the Model Bill circulated by Ministry.
Inclusion of Roof Top Rain Water Harvesting (RTRWH) in building by laws:
Maharashtra Government is promoting RTRWH under the “Shivkalin Pani Sthawan Yojana”. It provides that all houses should have provision for rainwater harvesting without which house construction plan should not be approved. Bombay Municipal Corporation and Pimpri - Chinchwad Municipal Corporation have made RWH mandatory by enacting building bye-laws.
