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