Natural Spring Water Harvesting

There is a natural spring on the site at the Sungure Khola Chiso Pani Dhara. The spring discharges at a minimum rate of 86,400 litres of water per day. This is collected in a stone cement masonry intake structure, filtered through fine sand, and taken through HDPE pipes to the training centre and field nursery area for drinking purposes.

Roof top rain water harvesting

Rainwater is collected from the rooftop of the Training Centre and training room

buildings and stored in ferro-cement jars. Each jar has a capacity of 2,000 litres and costs approximately NRs 5,000 (in 2012, approximately equivalent to US$ 140). It provides a useful source of drinking water and/or water for irrigation of a kitchen garden. The method is suitable for scattered houses in mountain areas where there are seasonal rains followed by long dry spells and no nearby perennial sources of potable water. It reduces the time spent by women and children (in most cases) in fetching water, and minimizes the risks of collecting water in the rainy season when paths are often slippery and difficult to negotiate.

Multiple Use of Water System (MUS)

It is a combined system of water facility that provides water for drinking and irrigation. It is a combination of transmission lines, reservoir tanks, distribution lines, domestic tap stands and irrigation systems. The Thai improved jar is used for collecting rain water harvested from rooftop and distributed for drinking and irrigation.

Water collection reservoirs

Water collection reservoirs have been constructed that take advantage of the Knowledge Park’s topography and the presence of perennial water sources to provide a simple and cost effective system of irrigation. Three water collection reservoirs have been constructed with high-density polyethylene sheet and SILPAULIN (multi-layered, cross-laminated, UV-stabilized plastic sheet) linings at suitable locations above the cropping plots. Water reservoirs can also be used for fish farming (see Livestock and Fish)
