Drinking water quality improvement through conservation measures

Structural and vegetative measures to improve the quality of drinking water contaminated due to poor sanitation and seepage

This technology combines structural and vegetative measures to improve the quality of drinking water in an open spring. The quality of water was deteriorating due to poor sanitation and seepage around the spring. The spring was located near to Dhotra village at Barbot sub-settlement, Kabhrepalanchok district. About five households depended on the spring for their drinking water supplies with a further 10 using it regularly and 10-15 using it occasionally during the dry season.

The main purpose of implementing the technology was to improve the quality of drinking water in the spring by preventing it from being contaminated by surface runoff during the rainy season. This technology has long been implemented across Nepal’s midhills. In this case a development project (PARDYP) mobilised the users and provided them with technical and material support to make the improvements.
