Hydrogeology

Physiographically, the State consists of narrow strip of hills running from east to south west and facing the Assam plains to its north and north east. The deep aquifers are thinly bedded down to 300 m. The water table rests within 4 mbgl except in some pockets towards Naga-Patkai hills where it goes upto 12 m bgl. The yield of tubewells on the bank of Dhansiri and Diphu rivers is around 2 m3/hr. The low yield is because of finer nature of aquifer materials. Besides the foothill zones, some intermontane valleys have also been observed like at Tijit, Tiru, Longnoth and Baghty valleys. Yield of the wells in these areas vary from 16 to 62 m3/hr. The thickness of saturated zone is 30 to 70m with in 300 m depth one an average, the wells of 250 m depth can yield between 20-30m3/hr. The quality of ground water is generally good.

Artificial Recharge to Ground Water (AR)

  • Feasible AR structures: 500 check dams, 1000 weirs, 1000 gabion structures, 300 roof top harvesting, 200 development of springs.

AR schemes completed during IX Plan: 3

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

In view of very low development of ground water, State Govt feels that the ground water regulation and management law may be deferred at present. However, the State has informed that the matter is being examined for necessary follow up action.

Inclusion of Roof Top Rain Water Harvesting (RTRWH) in building by laws:
The State Government has already made provision for roof top rainwater compulsory for all new Government buildings.
