International Code Council and CSA Group release updated Rainwater Harvesting Systems Standard
The International Code Council and CSA Group announced the publication of an updated joint standard for harvesting rainwater and stormwater. CSA B805/ICC 805-2022 Rainwater harvesting systems, which is available on the Code Council’s website, provides guidance to property owners, contractors, builders, architects and code officials on constructing new buildings or renovating existing buildings in ways to conserve water and protect water resources.
The updated standard provides design, material, installation and operation parameters for residential and commercial systems that safely utilize rainwater for potable uses such as human consumption, food preparation and bathing. It also provides parameters for systems using rainwater and/or stormwater for non-potable uses such as irrigation, fire protection and toilet/urinal flushing
