Hydrogeology
The diverse terrain conditions have given rise to different ground water situations in the State. The rock formations ranging in age from Archaean to recent include gneisses, schists, phyllites, intrusive, medium to coarse grained sandstones, basalts and recent alluvium. The high relief area in the eastern and north eastern part occupied by Archaean and Deccan Trap have steep gradient allowing high run-off and therefore have little groundwater potential. The yield of wells in these formations range from 5-10m3/hr. The yield in sandstones varies from 50 to 170 m3/hr. The yield of wells tapping Quaternary alluvium in Cambay basin ranges between 75-150m3/hr. There are five major aquifers in alluvial sediments out of which the top one has dried up due to over exploitation.

Enactment of Ground Water Bill to regulate and control the development of ground water:
Gujarat Ground Water Authority (GGWA) has been constituted vide Government of Gujarat, notification No. GWR/1095/61/I-1/J-1 dated 19.09.2001 for control and regulation of ground water resources. The State Govt. informed that the draft Bill is under process of finalization and suitable legislation will be enacted shortly.
Inclusion of Roof Top Rain Water Harvesting (RTRWH) in building by laws:
Metropolitan Areas have notified rules under which no new building plan is approved without corresponding rainwater harvesting structure. The D/o Roads & Buildings have been directed to ensure that all major Govt. constructions including educational institutions had adequate rainwater harvesting facilities. The Urban Development and Urban Housing Department has issued necessary orders Gujarat Town Planning Act, 1976 to incorporate the rules for RWH.
