Despite massive outlays for drinking water and sanitation in India, access to safe drinking water remains a challenge. This paper aims to the assessment of drinking water quality and sanitation situation in Krishnarajanagara town in terms of water supply system. The physicochemical and bacteriological analysis of supplied water for the drinking purposes in the town was carried out. Determination of water quality parameters were carried out at both source level (treatment station) and distribution level (residences) to know the status of drinking water supply system in the town. Residential chloride concentration present in the drinking water samples was determined at distribution level. Physicochemical parameters of all the drinking water samples were within permissible limit and safe for drinking.
