The work for this project generally includes dredging the western portion of the Waterford Pond located on the Glen Eagles Golf Course in Twinsburg, OH. The dredging work is to include dewatering the western portion of the pond, conducting a survey of the existing contours, removing accumulated sediment to bottom of original pond, and resurveying the pond to determine volume removed. The City has a site approximately 0.25 miles from the pond where sediment can be stored and dewatered, but ultimately the material must be hauled away. Contractor shall visit the site to view existing conditions and base their bid accordingly.

The work included in this project generally consists of general site work, Flow Equalization, Tertiary Treatment, and Disinfection improvements for the City of Twinsburg Wastewater Treatment Plant. The project includes a new 130-foot-long by 64-foot-wide by 18-foot-deep 1-million-gallon flow equalization basin, which will provide a total storage capacity of 3 million gallons. Other improvements involve enhancing cleaning operations with the use of tipping buckets, replacing the existing mixing system and adding a mixing system to the new EQ tank, replacing the EQ pump station pumps and drain pumps, and updating the overflow totalizing flow meter, instrumentation and level control for operations. New disc filter equipment will be installed to replace the existing microstrainers. The plan is to upgrade the existing facility with new equipment and perform necessary building improvements to meet code and streamline maintenance and operation of the filters in the future. The project includes replacing the current chlorine gas disinfection system with vertical UV disinfection. The existing chlorine contact tank will be modified to install the new UV disinfection system and a new canopy structure will be installed over the chlorine contact tank. The chemical storage rooms will be modified to accommodate the new electrical equipment. The project also includes miscellaneous site work items, new access stairs at the existing outfall, and a new generator. A mandatory pre-bid meeting will be held at the Wastewater Treatment Plant on November 12, 2025 at 10:30 AM. The address for the Twinsburg Wastewater Treatment Plant is 10231 Ravenna Road, Twinsburg OH 44087.
