Last year, ASPE/ARCSA/ANSI's Rainwater Harvesting Standard 63 was published to assist many areas of the United States with standardized plumbing guidelines for rainwater harvesting from roofs as a local alternate water supply.


Individuals can augment their personal water supply by supplementing utility water with rainwater harvesting. The mission of the 501(c)3 non-profit American Rainwater Catchment Systems Association ( is to promote sustainable rainwater harvesting practices to help solve potable, non-potable, stormwater and energy challenges throughout the world. A well-designed, installed and maintained rainwater harvesting system can provide high-quality water for potable and non-potable, residential and commercial uses. Harvesting rooftop water also reduces stormwater runoff and pollution, benefitting local water bodies.


To provide rainwater harvesting guidelines for areas of the United States not covered by ASPE/ARCSA/ANSI 63 and in Canada, the International Code Council (ICC) and Canadian Standards Association (CSA) formed the Joint Consensus Committee on Rainwater Collection System Design and Installation (IS-RCSDI), to produce the Standard for Rainwater Collection System and Design and Installation, BSR/CSA/ICC 805-201x. The resulting documents will be submitted for approval as both ANSI and SCC (Standards Council of Canada) accredited standards for use in the U.S. and Canada. As per the ICC and CSA code development processes, task or working groups are formed for assisting the Committee in drafting the provisions described in their respective scope statements for the Standard. One of the task groups, Treated Water Quality (Output), Applications and End Use, is chaired by ARCSA's Vice-President, Russ Jackson. This group's scope is to categorize water quality by application or use. End uses of rainwater include data center cooling, cooling tower makeup, landscape irrigation (surface and sub-surface), toilet and urinal flushing, pool and spa fill, hose bibs, vehicle washing, fire sprinklers, clothes washing, and even potable uses. Other task groups include: Storage Sizing, Source Water Quality (Input), and Control Systems and Design, which is chaired by ARCSA member Doug Pushard. Another ARCSA member on task groups: Ken Nentwig, who is also a member of CANARM, the Canadian Association of Rainwater Management, which has a Memorandum of Understanding with ARCSA.


More information about the ICC and CSA project is available at Besides the contributions by Jackson and Pushard, the ARCSA board and its membership are available to provide ICC and IS-RCSDI any rainwater harvesting expertise and guidance, based upon its mission and years of experiences.


ARCSA is the premier national educational and technical rainwater harvesting organization. Decentralized onsite rain- and stormwater harvesting systems can deliver a partial solution to our aging water delivery infrastructure and support new job creation.


ARCSA is currently accepting tax-deductible donations to produce a comprehensive rainwater harvesting manual written by its many experts and technical writers, and to host on-line and in-person training events across the country.


Consult ARCSA's website for rainwater harvesting systems, suppliers, trainings, and research information. For more information, contact Heather Kinkade, Executive Director, at 512-617-6528 or
