    Rainwater Harvesting system components

    The parts of a complete system include the catchment area (a roof), a rainwater conveyance system (gutters and leaders), holding vessels (cisterns), a roof-wash system (usually the first 10 -20 gallons of rain are diverted from the cistern), a delivery system (pumps) and a treatment system (filters and/or purifiers). Systems can be custom designed and built or purchased as a package. The components may be added by retrofitting existing gutter/leader and roof systems. Uncoated stainless steel or galvanized steel with a baked-enamel finish that is certified as lead-free are considered the best choices for rainwater catchment.
