SUA Project No. 12SG08
The City of Stillwater and Stillwater Utilities Authority is making improvements to the flow equalization basin (FEB) at the Wastewater Treatment Plant. The plant cleans the city’s sewer (wastewater) to a point where the effluent water can be discharged to a stream. The project consists of cleaning and removing all sludge, debris and grit from the FEB, replacing a sluice gate, adding new valves and sealing joints and cracks in the FEB walls.
The FEB plays an important role at the plant, providing 750,000 gallons of temporary storage for excess wastewater entering the plant during high flow periods, particularly during heavy rains. After the high-flow period subsides, the wastewater in the FEB is treated through the plant processes.
The project started in September 2015.
December 18, 2017: Construction has begun on the FEB's new concrete liner.
June 1, 2016: Phase 1 construction is complete. Sludge and debris were removed from the FEB, the sluice gate was replaced and a new valve was installed. Phase 2 is in design and will include joint and crack repair to the walls of the FEB, as well as upgrades to the existing liner.
February 3, 2017: Design efforts for Phase 2 are complete. The final corrections to the documents and assembly of contract are being conducted by the City's engineer.
June 16, 2017: Bids from Contractors have been received and staff are evaluating the submittals before making a selection.
August 10, 2017: Wynn Construction Co., Inc. was awarded the construction contract.
November 15, 2017: FEB has been drained for Restek to begin sealing cracks.
