Rainwater Harvesting

Rainwater is typically collected or "harvested" from two primary areas:

Rooftop Collection

Using a roof as a collection point, the water can be funneled into the rainwater storage tank by routing existing downspouts and gutters into the harvesting system or tank.

Land Surface Catchments

Ground catchment allows for the additional surface area of yard surface to be used to gather rainwater runoff and funnel it into. Various techniques can be used to improve the runoff capacity of land surface.

Both land and rooftop collection methods require a collection system to funnel it to the rainwater collection tank. Contamination from oil, sand or other debris may be an issue for either collection method and filtration may be necessary prior to water storage. Always sanitize collected rainwater prior to using for any potable water use.
