Analysis
This substitute ordinance defines a rain barrel as an above-ground prefabricated storage receptacle with an automatic overflow diversion system that collects and stores storm water runoff from the roof of a structure that would have been otherwise routed into a storm drain. A rain barrel must be securely covered, include an inlet screen, have an overflow discharge device and have a convenient and functional means of water withdrawal. The use of a rain barrel is permitted provided the overflow discharge conforms to the requirements of roof rainwater discharge to finished grade or is designed to overflow to a treatment drain or storm water conveyance system. The requirements of roof rainwater discharge to finished grade are as follows:
