Design standard offers latest guidance for implementing stormwater harvesting systems while protecting public health

The American Society of Plumbing Engineers (ASPE) and the American Rainwater Catchment Systems Association (ARCSA) are pleased to announce that the ARCSA/ASPE/ANSI 78-2023: Stormwater Harvesting System Design for Direct End-Use Applications eBook was approved as an American National Standard (ANS) by the American National Standards Institute (ANSI) earlier this year.

First published in 2015, ARCSA/ASPE/ANSI 78-2023 went through an extensive development process using ASPE’s ANSI-accredited standards development procedures to incorporate input from all facets of the building design and related industries. The Working Group, headed by Bob Boulware, PE, spent countless hours fine-tuning the standard based on public comments and input from ASPE’s Main Design Standards Committee to ensure that the standard meets current industry and government regulations.

ARCSA/ASPE/ANSI 78-2023 will 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. It applies to new stormwater harvesting installations, as well as alterations, additions, maintenance and repairs to existing installations. ARCSA/ASPE/ANSI 78-2023 continues where ARCSA/ASPE/ANSI 63-2020: Rainwater Catchment Systems ended, in terms of harvesting surfaces. It supersedes ARCSA/ASPE/ANSI 78-2015.

ARCSA/ASPE/ANSI 78-2023: Stormwater Harvesting System Design for Direct End-Use Applications is available for purchase as an eBook from the ASPE Bookstore.
