In Mewat, the ground water is depleting at the rate of about 25 cms a year and salinity is increasing in many parts. The rising water salinity is affecting crop yield and limiting the choice of crops that can be grown. About 80% of the total geographical area in Mewat is cultivated. Of this total cultivated area, only 44% falls under the irrigated area, the rest is rain fed area. For the irrigated area the source of water is almost exclusively (95%) ground water, but it is very limited, generally enough only for one crop a year. It also includes pockets of saline water which is not fit for cultivation of most of the crops grown in that area. About 30% of households own wells or tube wells. Fast ground water depletion and seasonal variation of tube well yields is a matter of concern leading to low crop intensity. This is especially true in the villages where IRRAD is working. To check these rising water concerns a tailor made, integrated water management plan was needed for each village, with the first step being the study of topography, water flow, soil characteristics and traditional knowledge. Subsequently, the designing of appropriate interventions to harness and conserve water is undertaken. To this effect, IRRAD has carried out technical interventions like the check dams, gully plugs, recharge wells, soak pits, roof water harvesting etc. Taking water as an entry point of development work, IRRAD has intervened in many villages, expanding its activities to 17 villages.

This handbook on roofwater harvesting by the IRC International Water and Sanitation Centre has been written to assist NGO and government staff responsible for implementing domestic roofwater harvesting systems or programmes. It is also meant to serve as a source of material for rainwater harvesting associations preparing national design guidelines in local languages.

Water Initiatives Orissa(WIO) and the Indian River Network (IRN) organsied the Odisha River Conference during 18 - 20 April 2009 at Sambalpur, Odisha.
