Hebron Lagoon Wastewater Treatment Plant, Hebron, North Dakota

Hebron Lagoon is a municipal wastewater treatment facility located in Hebron, North Dakota, serving a small population of 747 residents. The plant is situated in the Great Plains region, where cold winters and variable precipitation influence treatment operations. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater. With a designed capacity of 416.39 megaliters and an annual discharge volume of 302.83 megaliters, the facility operates below its capacity, indicating room for future growth. The plant's lagoon system is typical for small communities in the region, offering cost-effective biological treatment. Treated effluent is discharged into local waterways that ultimately drain into the Missouri River basin. The Missouri River system supports diverse aquatic life and provides water for agriculture and communities downstream. The plant's operations are regulated under the National Pollutant Discharge Elimination System (NPDES) to protect water quality in this ecologically important watershed.

Hebron Lagoon discharges into tributaries of the Heart River, which flows into the Missouri River. The Missouri River basin is a critical water resource for the northern Great Plains, supporting fish species such as paddlefish and pallid sturgeon, as well as migratory birds. The plant's secondary treatment helps reduce nutrient and organic loads, protecting downstream water quality in this semi-arid region where water availability is a key concern.
