Chestermere’s water infrastructure operates as an elaborate, well-coordinated system designed to support both the daily needs of its 28,000 residents and the recreational appeal of Chestermere Lake. Managed through a unique blend of partnerships and oversight, Chestermere’s drinking water and wastewater services are maintained by EPCOR, with a 20-year contract with the City. However, the lake itself, though central to Chestermere’s identity, serves a distinct purpose as an irrigation reservoir and is owned and managed by the Western Irrigation District (WID).
Drinking water is sourced from the East Calgary Regional Water Line, which connects to the Water Transfer Station (WTS). This station is crucial, acting as both a storage reservoir and a booster to ensure efficient water distribution through the city’s system of mains, valves, and hydrants. EPCOR is responsible for maintaining these systems, overseeing the city’s water distribution, wastewater collection, and water metering services.
Wastewater from Chestermere is collected via underground pipes and pumped through a series of lift stations to Calgary’s treatment facilities. Residents are reminded to properly dispose of fats, oils, and grease (FOGs) to protect wastewater infrastructure, keep pipes clear, and reduce strain on the system. Allow FOGs to cool, then pour them into a disposable container or can before placing them in the garbage. Liquid oils can also be disposed of at the City of Chestermere’s ECO Centre.
In addition to treatment and maintenance, EPCOR’s operational model includes constant attention to infrastructure health, such as the upkeep of 780 manholes and 244 hydrants. This ensures that residents have consistent, safe access to drinking water and reliable wastewater removal while safeguarding Chestermere’s potable water systems from potential contamination.
Chestermere Lake, formed in 1907, was originally designed as an irrigation reservoir to support agricultural lands between Calgary and Strathmore. Although the lake’s primary purpose has shifted to recreation, its management remains with the WID. At 4.8 kilometres long and 0.8 kilometres wide, with a maximum depth of 7 metres, the lake is a popular destination for activities like boating, fishing, windsurfing, and skating in the winter. The lake’s water volume is refreshed every five to eight days during the summer months, helping maintain water clarity. However, due to the lake’s shallow depth, aquatic weeds grow densely in certain areas, necessitating continuous mechanical removal by the City to keep the waters navigable and inviting.
The relationship between lakefront property owners and the WID has a complex history. In the 1990s, disputes over land ownership arose as the WID retained ownership of the lakebed and a “floodplain” buffer that included parts of lakefront backyards. After substantial advocacy, led by the Chestermere Lakefront Owners Association (CLFOA), the Town of Chestermere negotiated a purchase, allowing lakefront property owners to acquire pieces of lakefront and lakebed land. This landmark resolution reinforced community unity and highlighted the importance of the lake to local residents.
Maintaining water quality in Chestermere Lake is a community effort. While the lake’s water is not used for drinking, it is essential to keep it clean for recreation and environmental health. The WID conducts regular water quality tests, and since 2021, a CD3 Boat Cleaning System at the lake’s boat launch has helped prevent the spread of invasive species by providing tools for thorough cleaning. Residents also play a role by avoiding the use of lawn chemicals near storm drains, as these can flow directly into the lake, affecting water quality. The City of Chestermere, guided by the Alberta Safe Beach Protocol, also tests water quality weekly at popular beaches in partnership with Alberta Health Services.
Chestermere’s water systems—for potable water, wastewater, and recreation—are integral to the city’s functioning and quality of life. With careful oversight by EPCOR and the WID, along with active community engagement, Chestermere continues to balance urban water needs with the stewardship of its cherished lake.
