When connecting water, sanitary and storm service connections to City infrastructure, we will inspect the installation per the Master Indemnification Agreement and ensure the connections are compliant with Standard specifications for Water Services, Standard specifications for sewer construction and approved plans.
Residential water use is regulated by the Water Utility Bylaw. Additionally, the bylaws related to sewer deal with appropriate water use and drainage in and around your property, such as the Drainage Bylaw, the Wastewater Bylaw and the Lot Grading Bylaw.
There are also legal responsibilities for Cross Connection Control - the system that prevents contamination of Calgary's drinking water.
