Rain water harvesting is a technique of collection and storage of rainwater into natural reservoirs or tanks, or the infiltration of surface water into subsurface aquifers (before it is lost as surface runoff). One method of rainwater harvesting is rooftop harvesting. With rooftop harvesting, most any surface — tiles, metal sheets, plastics, but not grass or palm leaf — can be used to intercept the flow of rainwater and provide a household with high-quality drinking water and year-round storage. Other uses include water for gardens, livestock, and irrigation, etc.
The reasons for using rainwater harvesting systems answer three questions:
What: Rainwater harvesting will improve water supply, food production, and ultimately food security.
Who: Water insecure households or individuals in rural areas will benefit the most from rainwater harvesting systems.
How: Since rainwater harvesting leads to water supply which leads to food security, this will greatly contribute to income generation.

Community Exchange - Rainwater Harvesting
Here are conversations about rainwater harvesting (RWH) including best practices, troubleshooting, and advice about tanks and systems. Sourced from the Dgroups website, which is a free member-only forum, where people can ask a pool of over 3,000 members about rainwater harvesting. You can always become a member on their site for greater involvement, if you have questions you need to know for your RWH project. Go to the Community Exchange.
