Wastewater Treatment
Cleveland, Wisconsin
The village of Cleveland’s original wastewater treatment plant was constructed on the shore of Lake Michigan more than 25 years ago. By the early 1990s, the plant was at capacity and could not comply with new effluent and sludge storage standards. In addition, the treatment plant was located on a small site unsuitable for future expansions, and adjacent to existing and future park areas.
Wastewater Treatment Plant
The village completed a facilities plan in 1992 to address performance and site issues. The estimated cost to implement the facilities plan was nearly $5 million, resulting in a substantial monthly rate increase for village residents. Instead, the village selected Foth to re-visit the facilities plan and design a system which would address the existing plant’s shortcomings while keeping costs more affordable for residents. The revised plant location and design incorporates several features which resulted in a cost savings of more than $1 million to the village. The project was funded by the Wisconsin Department of Natural Resources Clean Water Fund low interest loan program.
Project Specifics:
Average daily flow ...................................300,000 gpd
Average daily BOD ....................................523 lbs/day
Average daily TSS ......................................500 lbs/day
Benefits:
- The new plant discharges to Lake Michigan via a 500-foot outfall. This allowed construction of a simple activated sludge system with biological phosphorous removal and fine bubble aeration.
- The new plant site layout is designed to accommodate future expansions.
- New raw wastewater pumps and variable frequency drives installed at the old plant site allowed the village to re-use the existing wet well.
- Sludge is treated via aerobic digestion, with liquid sludge storage.
