Danbury Sewage Lagoon is a municipal wastewater treatment facility located in Woodbury County, Iowa, serving a small population of 380 residents. The plant is situated in the rural Midwest, where wastewater infrastructure supports dispersed communities. As a lagoon system, it provides secondary treatment, which is typical for small agglomerations in the United States. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater. With a designed capacity of 378.54 cubic meters per day and an average discharge of 227.13 cubic meters per day, the facility operates below its capacity. The regulatory framework ensures that effluent meets state and federal standards before discharge. The treated effluent is released into local waterways that drain into the Missouri River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant plays a role in protecting downstream water quality in this agriculturally intensive region, where nutrient management is a key environmental concern.
Environmental context
The plant discharges into local streams that flow into the Missouri River, a major tributary of the Mississippi River. The downstream environment includes the Missouri River floodplain and the Gulf of Mexico, where nutrient loading from upstream sources contributes to hypoxic zones. The plant's secondary treatment helps reduce organic pollutants and suspended solids, supporting aquatic life in the receiving waters.
