The entire Certification Program is largely based on the CSA B805-18 Rainwater Standard, published in April 2018. This standard will be referenced in the 2020 national building code and concerns mainly contamination and water quality protection and mitigation. Additional information such as calculations for tank sizing and capacity, and a detailed outline for the development of a Water Safety Plan, are integral parts of the Standard. The program modules reference pertinent sections of the CSA Standard, as well as other published material from Canada and ARCSA (American Rainwater Catchment Systems Association), and research work from around the world.
The modules have been created as stand-alone webinar format videos, available online through the CANARM website. Registration, CANARM membership, and an exam are required for certification. General interest participation without certification is also encouraged, as the webinars are geared for the public, for RWH practitioners, and for decision-makers, developers, and educators.
