ASSE/ARCSA/IAPMO/ANSI Series 21000-2017, Professional Qualifications Standard for Rainwater Catchment Systems Personnel, has been designated as an American National Standard by the American National Standards Institute (ANSI), and is now available for purchase. The Series 21000 contains the uniform minimum requirements for qualified designers and installers of rainwater catchment systems, and inspectors of rainwater/storm water catchment systems.

The series was a result of requests for ASSE International to develop a standard for professionals who work on residential, commercial, and industrial rainwater and stormwater systems.

The standards within 21000 provide best practices for the design and installation of viable alternative water systems utilizing captured rainwater.

“The practices set in ASSE/ARCSA/IAPMO/ANSI Series 21000 can reduce the need for long distances of pumping, plumbing, heating, and treating, which in turn can save millions of dollars in energy costs,” said Working Group Chairperson Timothy T. Haley. “Properly designed, installed, and inspected alternative water systems can give landscaped and garden areas a source of water to replace the use of potable water for irrigation, and allow for watering during times of drought. These systems can also provide water for industrial applications. Additionally, rainwater capture systems can help mitigate the infiltration of pollution carried by heavy rains into our waterways. There are many other potential uses for captured rainwater as well — all of which have the potential to save costs and energy, and help lessen our footprint on the environment.”

Until now there was no consensus standard that set the minimum training requirements for rain water catchment professionals.
