Lucas WWTP | Secondary Treatment Plant in Lucas, Iowa

Lucas WWTP is a municipal wastewater treatment plant located in Lucas, Iowa, United States. The facility serves a small population of 224 residents, reflecting the rural character of the area. It is situated in Lucas County, along US 34, and is part of the state's wastewater infrastructure managed under federal and state oversight. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. Secondary treatment is the minimum required by the US Clean Water Act for municipal plants discharging to surface waters. The plant's designed capacity is 90.85 units, matching its current discharge volume, indicating full utilization of its capacity. The treated effluent is discharged into a local waterway, likely a tributary of the Des Moines River, which flows through central Iowa and eventually joins the Mississippi River. This discharge contributes to the overall water quality management in the Mississippi River Basin, supporting downstream ecosystems and water uses. The plant's operation is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Iowa Department of Natural Resources, ensuring compliance with water quality standards.

The plant discharges into a local stream that drains into the Des Moines River, a major tributary of the Mississippi River. The Des Moines River flows through agricultural and urban areas, and its water quality is important for downstream communities and ecosystems. The Mississippi River Basin supports diverse aquatic life and is a critical migratory corridor for birds and fish. The plant's secondary treatment helps reduce nutrient and organic loads, protecting local water quality and the broader river system.
