NRSA prepares hydrogeomorphological maps for Indian states

Quality drinking water is the foremost need for a healthy society. Towards this end, the Central Government of India has come out with special measures/schemes, especially in the rural areas and regions with specific quality related problems. The National Drinking Water Mission was established in 1986 as one of the five technology missions. The Mission was renamed as Rajiv Gandhi National Drinking Water Mission (RGNDWM) in 1991. For fulfilling the objective of the Mission in identification of cost-effective technologies for water supply programme, RGNDWM has sanctioned 135 R & D projects of which 89 have been completed.

Preparation of hydrogeomorphological maps by National Remote Sensing Agency on 1:50000 scale is underway, showing prospective ground water zones and priority zones and sites for planning recharge structures. So far 1732 maps have been prepared and handed over to States of Andhra Pradesh, Karnataka, Kerala, Rajasthan, Madhya Pradesh, Chhatisgarh, Jharkhand, Himachal Pradesh, Orissa and Gujarat. The success rate through usage of groundwater prospect maps ranges between 82 per cent in Madhya Pradesh to 100 per cent in Kerala.
