Section I: Integration With Other Water Supply Systems

Paper I.3

Rain Water Cistern System - A New Approach To Water Supply Improvements In Nepalese; Hills

Ajaya Mani Dixit


Nepal is a land locked country with 83% of its area occupied by mountains. More than 50% of the country's population live in the hills, majority of which still have to be provided with safe drinking water. Broken topography and settlement pattern in the hills have resulted in hundreds of water schemes serving limited house-holds. This has caused difficulties in implementation, operation, and maintenance of water supply systems.

Deforestation and landslides are gradually depleting suitable water_ sources in the hills. Landslides have also damaged existing water systems. Use of Rain Water Cistern System (RWCS) can improve water supply situation in the hills. Analysis of rainfall, house-hold status, and storage method show that the system can be developed as primary water supply system in acute water shortage areas, or as a supplementary system during dry periods,.

The crucial question in the use of Rain Water Cistern System is, will it be socially acceptable ? People in the hills use running water and not still water for drinking and cooking. Rain Water Cistern System is a new concept and is not in use. Greater efforts are needed on the part of implementing agencies to ensure its wider use in Nepal.
