Fog Water Collection
The Nepal Water from Fog Project (NWFP) began in the spring of 1997. It was initiated by Nepal Water for Health with the assistance of a volunteer from the Canadian Center for International Studies and Cooperation (CECI), and a dedicated committee in Canada. The goal of the NWFP was to improve access to potable water for remote villages in Nepal. The Project had two main components.
- Firstly, to assess the potential of fog water collection technology in the Nepali environmental context. This phase successfully completed clearly showed that fog water collection is a viable technology in Nepal.
- Secondly to implement full scale, community based fog collection projects where they are feasible.
The technology to collect water from fog consists of erecting a plastic woven mesh vertically in the path of moving fog. In Nepal the best conditions for this occur on hill or ridge tops from 2000m - 3500m ASL (above sea level) The tiny fog water droplets coalesce on the mesh and drip down into a collection system. The first step at a potential site is to erect 1m x 1m standard for collectors (SFCs). These are observed daily and the data is used to determine if a full-scale project is feasible.
NEWAH has tested different sites to asses the possibility of implementing such projects and the Eastern hills of Nepal has been tested most feasible and viable to implement fog water projects. Fog water projects are implemented to serve communities without alternative sources of water and those that cannot benefit from the standard gravity flow schemes. The following are the sites of NEWAH fog water projects supported by various donors.
