Onoway Wastewater Treatment System - Lac Ste. Anne County, Alberta Secondary Treatment Plant

Onoway Wastewater Treatment System is a municipal facility located in Lac Ste. Anne County, Alberta, Canada. It serves a small population of 602 residents, providing essential wastewater treatment for the rural community. The plant is situated near Township Road 550, reflecting its role in supporting local infrastructure. The plant operates at a secondary treatment level, which is appropriate for its small scale. Under Canadian regulations, wastewater treatment plants are typically governed by provincial guidelines, and Alberta's Environmental Protection and Enhancement Act sets standards for effluent quality. The plant's discharge volume of 384 cubic meters per day indicates consistent operation. The treated effluent is released into the local watershed, which ultimately drains into the North Saskatchewan River basin. This river system is ecologically significant, supporting diverse aquatic life and providing water for downstream communities. The plant's location inland, away from coastal areas, reduces direct marine impact.

The plant discharges into the local watershed within the North Saskatchewan River basin, which flows into the Saskatchewan River system and eventually reaches Hudson Bay. This inland location supports a mix of agricultural and natural landscapes, with the river providing habitat for fish species such as walleye and northern pike. The secondary treatment helps protect water quality in this ecologically sensitive region.
