The City of Calgary: Leading the way

Monitoring water loss

The City continually monitors our water distribution system for leaks. Some main breaks (or leaks) could go undetected for months if it weren't for The City's commitment to testing and evaluating the newest leak detection methods. District Metered Areas (DMA's) are tested to monitor water loss throughout the system and are instrumental in determining when new breaks or leaks occur.

Water pressure management

The City is also piloting Pressure Management Areas (PMA's) to track water pressure based on peak demand periods. PMA's help reduce water loss and may contribute to fewer main breaks because they actively control system pressure. The City's work in these areas ensures repairs are made in a timely manner, which minimizes damage caused by breaks or leaks in our water distribution system and reduces the costs associated with them. Plus, by proactively managing the water distribution system, The City saves thousands of litres of water every month.
