ARCSA / ASPE / ANSI 78-2015:
Stormwater Harvesting System Design for Direct End-Use Applications
Electronic Download (PDF)
This new plumbing engineering and design standard has been developed by a joint effort of the American Rainwater Catchment Systems Association (ARCSA) and the American Society of Plumbing Engineers (ASPE). The purpose of this Standard is to assist engineers, designers, plumbers, builders/developers, landscape and irrigation professionals, state and local government, and end users in implementing a stormwater harvesting system while protecting public health and safety. This Standard is intended to apply to new stormwater harvesting installations, as well as alterations, additions, maintenance, and repairs to existing installations. This Standard applies, for example, to the collection of stormwater from the transportation grid (vehicular parking, driving, or other similar surfaces), elevated parking structures, surface public right-of-ways, and storm drain systems. This Standard continues where ARCSA/ASPE/ANSI 63-2013: Rainwater Catchment Systems ended, in terms of harvesting surfaces.
