| Abstract |
The objectives of the project are to:
• design install and test a dew harvest system of a size that can provide about ten litres of condensate per day on average during the season for a family. The system will include collection, treatment, and storage of condensate.
• determine the economics of dew harvest systems and the degree to which these can be reliable supplements to drinking water needs of family or community.
Six different materials were tested for suitability to build practical dew harvest systems in coastal belt of Kutch. Polyethylene mixed with titanium and barium (PETB) was found to be high yielding, inexpensive, and easy to use. This has been used to build the roof-over-roof systems for families as well as larger ones for the community. The cost of such systems works out to about Rs. 100 / m2. Pilot scale systems of both types have been built and installed. |
