The basic unit of water resources assessment and planning is a watershed. Water resources management at a watershed scale requires both water supply and demand management which includes water conservation through rainwater harvesting, groundwater recharge, and recycling. The present study is aimed to assess the potential of water harvesting and to identify suitable sites for water harvesting structures in Kolayat watershed of Bikaner district in Rajasthan by using Geographic Information System (GIS) and Multi-Criteria Evaluation (MCE). Proposed methodology of water harvesting site selection has compared with traditional methods of site selection. In traditional practices, the location of the structure is selected by visiting the geographical areas and looking at the various drainage patterns, soil erosion, land use land cover, water storage areas, availability of insects/ animals, native population feedback and past experiences. These practices are entirely dependent on instincts and results of the selected zones are uncertain. However, geospatial analysis techniques like RS, GIS, and MCE are the innovative tools which can be used to determine suitable sites for rainwater harvesting structures based on the watershed characteristics. The soil conservation service model (NRCS curve number) has been used to estimate the runoff. Further, spatial analysis in GIS has been carried out considering MCE along with the Analytical Hierarchy Processes (AHP) to assess the water harvesting potential and to identify the optimum locations of rainwater harvesting structures.

Wastewater treatment is the process of cleaning domestic wastewater so it can be either reused for irrigation, or safely put back into lakes, rivers, groundwater etc. Untreated wastewater is a threat to the health of humans and the environment. Treatment before domestic use is simply called water treatment which refers to the process that water from wells and other natural sources undergo in order to be potable for human.The domestic Water Treatments involves treatment for potable or drinking purpose, Taste, Odour, Hardness, and Contamination. Treatment of the water that is used in domestic situations is vitally important for ensuring the health and safety of all who are drinking it. The water needs to be free from anything that can cause it to adversely affect the activities it is needed for. There are so many different things in the water that can cause it to affect ones health and safety. Microorganisms can cause problems like diarrhea, dysentery, and cholera. The way to get rid of these harmful substances from the water is by providing the home with a quality water treatment.
