The use of rainwater harvesting systems in Georgia can serve to supplement non-potable water demands while maintaining and enhancing the quality of the environment.
The Georgia Rainwater Harvesting Guidelines are intended to assist all parties involved in the design, construction, inspection and maintenance of rainwater harvesting systems and to help successfully comply with Appendix I-‘Rainwater Recycling Systems’ of the 2009 Georgia Amendments to the 2006 International Plumbing Code (IPC). The parties mentioned above include owners, building officials, design professionals and contractors.
Rainwater, for purposes of this document, is water collected from roof surfaces during rain events. This water is then stored in tanks or cisterns for later use. Potential uses include indoor non-potable applications (toilet flushing) and outdoor non-potable applications (irrigation systems, hose bibs, etc). Rainwater Harvesting (RWH) in its essence is the collection, conveyance and storage of rainwater. Rainwater collected from roofs is not “recycled water”, nor is it “gray water”. It is fresh water that is in abundant supply, and is generally undervalued in the United States. (2009)
