Lagoon Site Wastewater Treatment Plant, County of Vermilion River, Alberta

Lagoon Site is a wastewater treatment plant located in the County of Vermilion River, Alberta, Canada. It serves a small population of 276 residents, reflecting its role in a rural community. The plant is operational and provides secondary treatment, which is typical for small-scale facilities in the region. As a secondary treatment plant, Lagoon Site meets the basic regulatory requirements for wastewater treatment in Alberta. The province's environmental regulations, enforced by Alberta Environment and Parks, mandate that municipal wastewater undergo secondary treatment to reduce organic matter and suspended solids. This level of treatment is appropriate for the plant's small service population and helps protect local water quality. The treated effluent from Lagoon Site is discharged into the local watershed, which ultimately drains into the North Saskatchewan River basin. This river system flows through central Alberta and eventually joins the Saskatchewan River, contributing to the larger Nelson River drainage basin that reaches Hudson Bay. The plant's operations are important for maintaining the ecological health of these downstream water bodies.

The plant discharges into the local watershed within the North Saskatchewan River basin, which flows eastward through Alberta and Saskatchewan. The receiving waters support diverse aquatic life, including fish species such as walleye and northern pike. Downstream, the river system contributes to the Nelson River drainage, which empties into Hudson Bay, making the plant's effluent management crucial for both local and far-field water quality.
