In Rajasthan total 22254 habitations are quality affected (as on 1-4-15) out of which 7056 habitations are fluoride affected 13814 habitations are salinity affected.1370 are nitrate affected and 14 are iron affected. To provide potable water to these habitations is top priority of state government. As providing water through sustainable surface sources particulary in Rajasthan is a time taking solution therefore state government has planned to give interim relief to these quality affected habinations by providing potable water through installation of community water purification plants based on Reverse Osmosis (RO) technology by treating the in-site ground water. The scheme is being implemented in pahsed manner, where approx 1000 RO plants have been installed in 13-14 and another 1000 plants under implementation in 16-17. Orders have been issued for 1000 plants in 2017-18 for which work will commence shortly.
