Hydrogeology
The predominantly hilly State of Uttarakhand has a varied hydrogeological setup and can be divided broadly into two distinct hydrogeological regimes viz. the Gangetic alluvial plain and the Himalayan mountain belt. The former is covered with a vast expanse of alluvium and unconsolidated sedimentary material of varying size fractions (ranging from boulder to clay) and is a promising zone for ground water development. The latter zone, being predominantly hilly, offers much less potential for large scale development of ground water. Ground water in the hilly region occurs mostly in fissures/fractures and emerges as springs. The springs are amenable to small scale development of ground water resources in the State. The yield of tube wells in Siwalik formation ranges from 50.4 m3/hr to 79.2 m3/hr, in Bhabar formations yield is upto 332.4 m3/hr. In Tarai belt yield of tubewell ranges 36m3/hr to 144 m3/hr and in Indo-Gangetic plain yield varies from 90 m3/hr to 198 m3/hr

Enactment of Ground Water Bill to regulate and control the development of ground water:
Draft Bill has been prepared on the lines of Model Bill in consultation with Central Ground Water Board. Necessary action for approval of the State Cabinet is being taken before the Bill is introduced in the Assembly.
To be enacted.
Inclusion of Roof Top Rain Water Harvesting (RTRWH) in building by laws:
The Govt. of Uttarakhand (Awas evam Shahari Vikas) has made rules for compulsory installation of RWH system and directed to adopt rules in building Bye-laws vide order dated 15.11.2003. Accordingly, all the Development Authorities had made partial amendments in the prevalent House Building and Development Bye-laws/Regulations.
