RUDD WWTP - Secondary Wastewater Treatment in Rudd, Iowa

RUDD WWTP is a municipal wastewater treatment facility located in Rudd, Floyd County, Iowa, United States. The plant serves a small community of 369 residents, reflecting its role in managing local domestic wastewater in a rural setting. The plant operates at the secondary treatment level, which is the standard requirement under the U.S. Clean Water Act for municipal wastewater treatment. With a designed capacity of 227.12 cubic meters per day and an average daily discharge of 189.27 cubic meters, the facility operates below its capacity, indicating adequate headroom for current demand. The treated effluent is discharged into a local watercourse that ultimately drains into the Upper Mississippi River basin. This region is part of the larger Mississippi River watershed, which supports diverse aquatic ecosystems and provides drinking water for millions downstream. The plant's secondary treatment helps reduce organic pollutants and protect water quality in the receiving waters.

The plant's discharge enters a tributary of the Cedar River, which flows into the Iowa River and then the Mississippi River. The Upper Mississippi River basin is ecologically significant, supporting diverse fish populations and migratory birds. Secondary treatment reduces biochemical oxygen demand and suspended solids, helping maintain water quality in this agriculturally influenced watershed.
