Abstract
Water is an essence of human life and India is blessed with many rivers, lakes and ponds contain plenty of water. They are perennial or seasonal, depends on the monsoon. Global climate change and increase the demands by the various water users, priority to conserve the water in a storage structure during the rainy season and use during the lean period is the need of the hour. Water storing in the pond faces seepage and evaporation losses issue. Reduction of seepage losses at the bottom and sides of the pond can be achieved by laying plastic sheets, one of the promising techniques, researches revealed. 200-micron thick plastic sheet laid in 2:1 stable side slope of pond is the common practice. This method maximizes water storing period and multiple uses of water.
