Water Harvesting with CisternsCisterns are widely defined as large buried or above ground containers that traditionally serve the purpose of harvesting water. The word traditionally is use in the sentence before because in many parts of the world cisterns are also manually filled and not used for water harvesting. Properly using cisterns can lead from a more lush landscape to a home self sustained green home complete with its own water supply for plumbing.

Types of cisterns - differ from water tanks in the fact that they have removable tops and typically use gravity to disperse water and not pumps. Most homeowners thinking of deploying cisterns have moved beyond the step of contemplating water harvesting for only landscaping. Many of today's cisterns serve as plumbing for toilet and showers and with the proper filtration and water testing can be use for human consumption.

Water harvesting is the process of redirecting and productively using rainfall which can benefit the environment, conserve local resources, lower monthly utility bills and even keep your lawn alive when everyone else's are dying. A summer downpour that delivers a � inch of rain can drop enough water on the average roof to fill a 50 gallon container for used in the yard and home or contribute waste water to city sewer systems.

Calculating Water Harvesting - Understanding that an inch of water per square foot = .623 gallons and knowing the average annual rainfall amount in your city, you can estimate the amount of water that can be collected from your roof.
