Overview
AURORA STL is a secondary wastewater treatment plant in Buchanan County, Iowa, serving a small population of 194. It discharges treated effluent into local waterways, supporting the region's water quality.
AURORA STL is a municipal wastewater treatment facility located in Buchanan County, Iowa, United States. The plant serves a small community of 194 people, providing essential sanitation services for this rural area in the state's northeastern region. The plant operates with secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater facilities. Secondary treatment typically involves biological processes to remove organic matter and suspended solids, ensuring that the effluent meets federal and state water quality standards before discharge. The treated wastewater is released into local receiving waters, which ultimately drain into the Mississippi River basin. This contributes to the protection of downstream aquatic ecosystems and supports the overall health of the region's water resources. The plant's location inland, away from coastal areas, reduces direct marine impacts.
Environmental context
The plant discharges into local streams that are part of the Upper Mississippi River basin. This watershed supports diverse aquatic life and provides habitat for fish and migratory birds. The Mississippi River eventually flows into the Gulf of Mexico, where nutrient loading from upstream sources can contribute to hypoxic zones. Proper treatment at plants like AURORA STL helps mitigate such downstream effects.
