This study was estimating the physicochemical parameters of water and preparing the water quality index for drinking water in a residential area of Bilaspur city. Fifty water samples were collected from ten sites and analyzed six parameters of water quality by using the portable multi-parameter water quality meter (Hanna Instruments: HI98194). The results of water quality were statistically different for sites (p<0.001). During the study, the average water pH (8.326±0.67), water temperature (27.349±0.207 °C), dissolved oxygen (7.775±0.034 mg/l), total dissolved solids (526.46±0.781mg/l), electrical conductivity of water (391.6±0.79 mg/l), and oxygen reduction potential (-32.715±0.21 mV) were recorded. The positive correlation was observed between EC and TDS (r = 0.935) and pH and ORP (r = 0.802), while the negative correlation was observed between DO and temperature. The range of the WQI was observed to be 383.67 to 530.87, and there was a statistically difference at for sites (p<0.001).
