The present study aimed to calculate water quality index (WQI) in order to assess the suitability of water for domestic use and drinking purposes.Water quality index (WQI) is valuable and unique rating to depict the overall water quality status in a single term that is helpful for the selection of appropriate treatment technique to meet the concerned issues. Water quality analysis were carried out on surface samples collected from three sampling sites Sahebkhedi lake, Undasa wetland and Purushottam sagar of Ujjain Dist. for the month of May 2017 to June 2018. The analysis of different parameters namely -pH, Hardness, Calcium, Chlorides, Alkalinity, D.O., BOD were carried out as per standard methods, prescribed as in the APHA (2005). The present study concludes that these water bodies are not fit for drinking purpose and domestic use because it accounts for high anthropogenic activities, worship rituals and several thousands of pilgrims take hoy bath.
