Abstract
In order to understand the quality of drinking water supply in Kathmandu metropolitan city, physico-chemical characteristics were studied and analyzed. Various physico-chemical parameters, such as turbidity, water temperature, pH, conductivity, total alkalinity, total hardness, calcium, magnesium, chloride, iron and total ammonia were studied and compared with National Drinking Water Quality Standard (NDWQS) of Nepal and WHO water quality guidelines. The results revealed that most of the parameters were in normal range and indicated suitability for drinking purposes.
