Calgary experienced a significant loss of treated water, with 23% of its supply lost to leaks in the distribution network last year. This issue has persisted, with losses ranging from 20% to 24% since 2019. The city attributes these losses to aging infrastructure, including over 5,500 km of pipes and various service connections. In response, the city has introduced the Accelerated Water Loss Program, which aims to reduce water loss to 15% by 2030. This plan includes enhanced leak detection, improved measurement systems, and a commitment to replace 10 km of water main pipes in 2026, increasing to 15 km annually from 2027. The city administration has proposed a budget of $342 million for the next four years, emphasizing that investing in infrastructure is more economical than constructing a new water treatment facility. City councillors are currently debating the funding during upcoming budget discussions, highlighting the urgency of addressing the city's water loss crisis.
