Chestermere’s Wastewater System

Chestermere’s wastewater system is comprised of a 74km network of gravity sewer, more than 15km of forcemain and 13 lift stations. The City’s wastewater is collected at Lift Station (LS) 10 and pumped to the City of Calgary for treatment through a 450mm forcemain. A 250mm forcemain is inactive and on standby for use in emergency situations.

Wastewater Management

Water becomes wastewater when it runs down a drain or toilet. Wastewater is collected from homes and commercial buildings throughout Chestermere via a series of underground pipes. This wastewater, or sewage, eventually flows to a lift station by gravity, where it is pumped from the lift station to a higher elevation, and eventually from the last lift station to the City of Calgary for treatment at their wastewater treatment plant.

Although CUI owns and operates the infrastructure within the City of Chestermere, our wastewater is processed by the City of Calgary, where it moves through a variety of pump stations, clarifiers, filters, fermenters, and digesters before being re-introduced to the environment as biosolids for agriculture or oxygen-rich river water.

Chestermere Lift Stations

Lift Stations are used for pumping wastewater, or sewage, from lower to higher elevations. Since Chestermere is very flat, the elevation is not enough for sewage to flow by gravity to its end destination – the wastewater treatment plant in the City of Calgary. Click here for more information.

Protect Your Plumbing, Our Wastewater System, and the Environment

Putting fats, oils, and grease (FOGs) down the sink can clog your pipes, reduce plumbing flow and harm our wastewater infrastructure; while objects like dental floss, tissue, and rags can lead to sewer backups. Please dispose of these items responsibly.

DO NOT dispose of fats, oils, and greate in your sinks, drains or toilets!

DO dispose of solidified fats, oil and grease in your green cart:

  • Scrape your plates and dishes into your kitchen compost pail before washing
  • Solidify fats and grease by cooling it at room temperature or in the fridge / freezer.
  • Wipe your cooking equipment and solidify your oil by mixing it with an absorbent material such as a paper towel or napkin, sawdust or kitty litter; put the mixture in a certified compostable bag or paper bag.
  • Dispose of fats, oil and grease in your green cart.

Liquid oils can be disposed of at the recycle depot:

  • Collect your used cooking oil in a plastic or glass container.
  • When ready, bring your container to the recycle depot. (There is no volume restriction).
  • Pour the cooking oil into the bulk tank.
  • Dispose of the plastic or glass container at the site or take it back home to refill and reuse again.
