Savanna New WWTP - Projected Wastewater Treatment Plant in Savanna, Illinois

Savanna New WWTP is a planned wastewater treatment facility located at 399 Oak Street in Savanna, Carroll County, Illinois. The plant is projected to serve a population of about 5,967, placing it in the small to medium agglomeration category for US municipal wastewater systems. As a projected facility, specific treatment processes and capacity details are not yet finalized. Under the US Clean Water Act, plants of this scale typically require secondary treatment as a minimum, with NPDES permits issued by the Illinois Environmental Protection Agency to regulate discharge quality and protect receiving waters. The plant's treated effluent will discharge into local waterways that drain into the Mississippi River basin, ultimately reaching the Gulf of Mexico. This downstream connection underscores the plant's role in regional water quality management and the protection of aquatic ecosystems in the Upper Mississippi River watershed.

The plant will discharge into tributaries of the Mississippi River, which flows south to the Gulf of Mexico. The Upper Mississippi River supports diverse aquatic life, including fish and migratory birds, and is ecologically sensitive to nutrient loading. Proper treatment at Savanna New WWTP will help reduce downstream impacts on this major river system.
