Evansburg Wastewater Treatment Plant, Entwistle, Alberta

Evansburg Wastewater is a municipal treatment facility located near Entwistle in Parkland County, Alberta, Canada. The plant serves a small population of 526 residents, providing secondary treatment to meet provincial and federal wastewater standards. As a small-scale facility, it plays a key role in protecting local water quality in this rural region of central Alberta. The plant operates with secondary treatment, which involves biological processes to remove organic matter and suspended solids. Secondary treatment is the standard requirement for municipal wastewater in Canada under the Canada-wide Strategy for the Management of Municipal Wastewater Effluent. This regulatory framework ensures that facilities of this scale meet minimum effluent quality standards to safeguard receiving waters. The treated effluent from Evansburg Wastewater is discharged into the local watershed, which ultimately drains into the North Saskatchewan River basin. The North Saskatchewan River flows eastward through Alberta and Saskatchewan, eventually joining the Saskatchewan River system and draining into Hudson Bay. This river system supports diverse aquatic life and provides drinking water for downstream communities, making effective wastewater treatment essential for environmental and public health protection.

The plant discharges into the North Saskatchewan River basin, a major tributary of the Saskatchewan River system that flows into Hudson Bay. This watershed supports fish species such as walleye and northern pike, and provides habitat for migratory birds. The river is also a source of drinking water for downstream communities, so maintaining high effluent quality is critical to prevent nutrient loading and protect aquatic ecosystems.
