Updated Rainwater Catchment Systems Design Standard Available

The American Society of Plumbing Engineers recently announced ARCSA/ASPE/ANSI 63-2020: Rainwater Catchment Systems has been designated as an American National Standard by the American National Standards Institute and is available for purchase.

Jointly developed by ASPE and the American Rainwater Catchment Systems Association, the standard is designed to assist engineers, designers, plumbers and other end users in safely implementing a rainwater catchment system using precipitation from rooftops and other hard, impervious surfaces.

The collected rainwater can be subsequently used for irrigation, laundry, hygiene or even potable water applications if the appropriate treatment and materials have been certified for the specific end use.

The standard went through an extensive revision and public review process using ASPE’s ANSI-accredited standards development procedures to incorporate input from numerous industries. The working group, headed by E.W. Bob Boulware, P.E., MBA, ARCSA AP, was tasked with vetting comments and proposed revisions to ensure the standard met industry and government regulations regarding reclaimed water use.

ARCSA/ASPE/ANSI 63-2020 supersedes the previous 2013 version. For more information, visit aspe.org.
