Stillman Valley New WWTP - Advanced Wastewater Treatment in Von Glen Acres, Illinois

Stillman Valley New WWTP is a projected wastewater treatment facility located in Von Glen Acres, Illinois, within Ogle County. Designed to serve a population of 1,624, the plant will provide advanced treatment for the community's wastewater needs. The facility is situated in an inland area, far from coastal influences, and will play a key role in managing local water quality. The plant will employ advanced treatment processes, which exceed the secondary treatment standards required under the US Clean Water Act. With a designed capacity of 757.08 cubic meters per day, it is sized appropriately for the projected population. As a new facility, it will operate under the National Pollutant Discharge Elimination System (NPDES) permit program, ensuring compliance with federal and state regulations. The treated effluent will be discharged into a local water body that ultimately drains into the Rock River, a tributary of the Mississippi River. This river system supports diverse aquatic life and provides recreational opportunities. The advanced treatment level will help protect downstream water quality and ecological health in the Mississippi River basin.

The plant discharges into a local stream that flows into the Rock River, which then joins the Mississippi River. The Mississippi River basin is a major ecological corridor supporting numerous fish species, migratory birds, and aquatic habitats. Advanced treatment at this plant will help reduce nutrient loading and protect water quality in this important river system.
