Alberta Guidelines for Residential Rainwater Harvesting Systems are recommended for the safe design, construction and maintenance of residential rainwater harvesting systems. The guidelines provide additional information that is not included in the current plumbing code and supports conformance to CAN/CSA 128.1 Design and Installation of Non-Potable Water Systems/Maintenance and Field Testing of Non-Potable Water Systems. The Alberta Building Code and the National Plumbing Code requirements have precedence over these guidelines.
In addition to the guidelines, a rainwater harvesting handbook was developed to provide broader understanding of the technical components of the guidelines. Below are links to both documents.
