Water harvesting means capturing rain where it falls or capturing the run-off in the village or town. Water harvesting is an excellent way to capture and utilise the natural rainfall, otherwise going to waste.
Gutters and clean drains are required to gather and direct the water to suitable storage tanks and reservoirs.
Water harvesting can also be done with collection pads from concrete on the sides of hills - these are broad, concave pads with a depressed gutter in the centre that capture rainwater and funnel it into a tank at the foot of the pad.
Many different water storage options vary in size. The bigger the population and scarcity of water, the bigger the tank required. The greater the tank size and distance, the higher the cost.
Cost & Impact: Higher installation cost, low maintenance cost.
Project Locations: Nepal & Southeast Asia
