Waterloo Wastewater Treatment Facility
The recently completed and operational City of Waterloo Wastewater Treatment Facility has received a Merit Award in the 39th Annual Engineering Excellence Awards competition, sponsored by the American Council of Engineering Companies of Illinois. Continued growth and maintaining three wastewater treatment plants caused the City of Waterloo to investigate constructing a single wastewater treatment plant with reserve capacity to handle 20-year growth.

The cost effective solution was to construct a new plant adjacent to the existing East Plant. The new 2.086 MGD plant includes a mechanical bar screen, grit chamber, four sequencing batch reactors (SBRs), non-potable water system, two aerobic digesters, belt filter press, and liquid and dried sludge storage. A new pump station at the West Plant was also constructed to direct flow to the new plant.

The total project construction cost was $11.5 million. David Rodden, P.E., was the Henry, Meisenheimer & Gende principal in charge and project manager.
