Current law authorizes the collection of rooftop precipitation from a single-family residence or a multifamily residence with 4 or fewer units (small residence). The bill removes the 100-gallon limitation on the amount of rooftop precipitation that may be collected from a small residence and removes all limitations on how the collected precipitation may be used. The bill allows for collection of any amount of precipitation for any use on the property of a small residence.
