High TDS in the drinking water has adverse effects on the health as per the drinking water standards (IS:10500). The permissible value of TDS for safe drinking of water is below 500 mg/l. In the survey, it has been found that in the western Rajasthan, the TDS in the groundwater at most of the places varies between 1100 to 6700 mg/l, which is unfit for drinking. Under the NRDWP (2009) scheme of Government of India, the habitation comes under “critical habitation” and there is a need to supply potable water through tankers or through Regional Water Supply Schemes by the PHED, Government of Rajasthan for drinking purposes. Recently Jal Jeevan Mission (JJM) by Government of India initiatives emphasizes to provide pipe water supply till 2024 to all households. In order to utilize the High TDS water which is available in the groundwater through Tube wells, Open well, there is need for its treatment through RO-Plant. During the RO-Treatment process, 20~50% of water comes as RO-Rejects having much higher TDS value which is currently discharged on the open land, nearby water bodies or infiltrate to the groundwater further leading to spoiling of soil and groundwater quality in the region simultaneously affecting the health of human being and fertility of agricultural field signaling reduction in crop yield and change in crop pattern. The evaporation of RO-Reject through solar at decentralized as well as centralized location has been found feasible due to availability of ample sunshine radiation in the western part of Rajasthan.
