Overview
GRAFTON LAGOON serves approximately 4,284 residents in Grafton, North Dakota. The plant operates under the US Clean Water Act, which mandates secondary treatment for municipal wastewater facilities.
GRAFTON LAGOON is a municipal wastewater treatment facility located in Grafton, Walsh County, North Dakota. Serving a population of about 4,284, it is classified as a small agglomeration under US regulatory frameworks. The plant's lagoon system is typical for small communities in the region, providing treatment through natural biological processes. Under the US Clean Water Act, municipal wastewater treatment plants are required to meet secondary treatment standards, which typically achieve at least 85% removal of biochemical oxygen demand and total suspended solids. For small communities like Grafton, lagoon systems are a common and cost-effective approach to meeting these standards, often with lower energy and operational costs compared to mechanical plants. The treated effluent from GRAFTON LAGOON is discharged into local waterways that ultimately drain into the Red River of the North, which flows northward into Lake Winnipeg in Canada. The Red River basin supports diverse aquatic life and is an important migratory corridor for waterfowl. Proper treatment is essential to protect downstream water quality and ecosystem health.
Environmental context
The plant discharges into the Red River of the North basin, which flows north through Manitoba, Canada, into Lake Winnipeg. This watershed is ecologically sensitive, supporting diverse fish species and serving as a critical stopover for migratory birds along the Central Flyway. Nutrient loading from wastewater can contribute to algal blooms in Lake Winnipeg, making effective treatment important for downstream ecosystem health.
