Hydrogeology

The entire foothill belt running along the Himalayan front can be correlated to the “Bhabar belt” of Ganga basin with exception of some areas of Lohit and Tirap districts. Ground water occurs under unconfined to semi-confined conditions. In Namsai and Mino sub-divisions, the depth to water levels is essentially governed by topography. Sediments down to 106 meters below ground level (m.bgl) are predominantly sandy and discharge of tube wells ranges up to 160 m3/hr. Open wells in Namsai and Mino sub-division tap 3 to 5 m of saturated sand and yield up to 100 m3/day.

Enactment of Ground Water Bill to regulate and control the development of ground water: 

In view of very low development of ground water, the State has not enacted any legislation for regulation of ground water.
 
Inclusion of Roof Top Rain Water Harvesting (RTRWH) in building by laws:
Building  Bye-laws are being framed keeping provision for RWH as mandatory in Government Buildings.  To be included.
