Water, wastewater and stormwater systems

We are responsible for the design, build and repair of three water and waste water systems:

Drinking water

We provide safe reliable drinking water to over one million Calgarians, Airdrie and Chestermere. Two water treatment plants and a network of pipes, water mains, reservoirs and pump stations deliver water to our customers each day. Learn more about where Calgary's drinking water comes from.

Water and wastewater rates

Visit the water and wastewater rates section for current water rates, information on how to read your water bill and to view answers to the most common questions we receive from our customers.

Wastewater system

The sewer system protects our health and environment by collecting and treating wastewater from homes, schools, hospitals, and businesses. Wastewater enters through sinks, toilets, bathtubs and washers, where it travels down sanitary pipes to three wastewater treatment plants. Learn more about Calgary's wastewater system.

Storm drains

The storm drainage system helps prevent flooding by moving rain and melted snow into the nearest river or creek with drains, manholes and pipes. The system also has dry and wet ponds to hold water during rain. Learn more about Calgary's stormwater drainage system.

Water construction projects

Ongoing projects to improve and expand our water and waste water systems and mitigate potential flooding issues in our storm water system. This includes new projects, infrastructure upgrades, repairs and maintenance, and flood recovery projects.
