Planning Water Harvesting and Storage Systems

Rainwater harvesting systems are orderly schemes in which organized components and techniques

harness and make rainwater available for human consumption and environmental conservation.

 Pave artificial catchment Thus, the planning and design of rainwater harvesting and storage in various structures should be

based on water supply for multiple uses. This is because communities in the target areas may use

the water not only to grow crops, but also for domestic use, livestock watering, as well as industrial

and commercial purposes.

Thus, a good quality RWH system is planned to provide communities with access to an on-site

water supply, if possible at home, or near their homesteads, or at locality that is easy to access.

Ideally, the RWH collection system should involve basic construction techniques, be inexpensive

to maintain, and have a long functional life span. If the system is designed well, it should provide

a good safe source of water at a relatively low cost when compared to the conventional methods

such as river diversion or ground water pumping.

Illutration of water requirement in rainwater harvestingIn order to determine whether or not rainwater catchment systems are an appropriate choice of

water supply in any given situation it is necessary to estimate the potential rainwater yield to check

that it can meet the required demand. The reliability of the systems along with technical, socioeconomic

and environmental considerations must be compared with all alternative forms of
