Lost Lake Utility District WWTP - Lost Nation, Illinois Wastewater Treatment Plant

Lost Lake Utility District WWTP is a municipal wastewater treatment facility located in Lost Nation, Illinois, within Ogle County. The plant serves a small population of approximately 500 residents, providing secondary treatment to manage domestic wastewater from the local community. As a secondary treatment plant, it meets the minimum standard required under the US Clean Water Act for municipal wastewater facilities. The plant has a designed capacity of 378.54 cubic meters per day and currently discharges an average of 227.13 cubic meters per day, indicating operational capacity below its design limit. US plants of this scale typically operate under National Pollutant Discharge Elimination System (NPDES) permits issued by the Illinois Environmental Protection Agency. The treated effluent is discharged into local waterways that drain into the Rock River basin, ultimately contributing to the Mississippi River system. This watershed supports diverse aquatic life and provides water resources for communities downstream. The plant's location inland, away from coastal areas, reduces direct marine impact but still requires careful management to protect freshwater ecosystems.

The plant discharges into the Rock River watershed, which flows into the Mississippi River and eventually the Gulf of Mexico. This inland basin supports a variety of fish species and provides habitat for migratory birds. The secondary treatment process helps reduce organic pollutants and suspended solids, protecting water quality in the receiving streams and downstream environments.
