Rockford WWTP - Secondary Wastewater Treatment in Rockford, Iowa

Rockford WWTP is a municipal wastewater treatment facility located in Rockford, Floyd County, Iowa. The plant serves a small population of 907 residents, providing essential sanitation services for the community. As a secondary treatment plant, it meets the standard requirements for organic matter and suspended solids removal under the US Clean Water Act. The plant has a designed capacity of 454.25 thousand gallons per day and currently treats an average daily flow of 340.69 thousand gallons per day. This indicates operational headroom for future growth. The facility operates under the National Pollutant Discharge Elimination System (NPDES) permitting program, which sets effluent limits to protect receiving water quality. The treated effluent is discharged to local streams that drain into the Cedar River watershed, ultimately reaching the Mississippi River. This water body supports diverse aquatic life and provides recreational opportunities. The plant's performance is critical for maintaining downstream water quality in this agriculturally intensive region.

The plant discharges into tributaries of the Cedar River, which flows southeast to the Iowa River and then to the Mississippi River. This watershed supports diverse aquatic species and is important for regional biodiversity. The surrounding area is predominantly agricultural, so the plant helps mitigate nutrient and pollutant loads that could otherwise impact downstream ecosystems.
