The purpose of this handbook is to outline the best installation practices for rainwater harvesting systems in the City of Calgary. The document highlights The City of Calgary Development and Building Approvals (DBA) permitting and inspection process for a person or company installing a residential rainwater harvesting system for use within buildings. Although this handbook focuses on residential rainwater harvesting systems, the overall principles will apply to institutional, commercial and industrial buildings, with the need for professional engineering and oversight when required.
Where appropriate, this handbook refers readers to the Alberta Building Code (2006), National Plumbing Code (2010), National Standards of Canada (2007), the Alberta Guidelines for Residential Rainwater Harvesting Systems Handbook (2010), and The City of Calgary Water Resources document titled Comprehensive Guide for Rainwater Harvesting as a Stormwater Best Management Practice. Please consult these documents for additional details, rules and regulations.
