The City of Stillwater and the Stillwater Utilities Authority will be rehabilitating the chlorine scrubber and replacing the chlorine feed system at the Water Treatment Plant (WTP).
The chlorine system is aging and deteriorating. WTP staff currently rely on outdated instruments for measurement and control. The chlorine system replacement will include new cylinder regulators, chlorine feeders and fine-tuned measurements and control. The chlorine scrubber rehabilitation will extend the life of the scrubber.
February 7, 2017: Black and Veatch has been hired to provide conceptual design services.
March 12, 2018: After evaluation most of the process and chemical feed systems at the WTP, a priority has been assigned to each individual component. The Project Team will prepare a Facilities Plan to develop a conceptual and phasing plan for the work to include the chlorine system.
December 10, 2018: A 65% Design Workshop was held with Project Team members. The chlorine design effort was put on hold until the Facilities Plan is complete. This will minimize the number of phases needed to construct the new chlorine system.
April 15, 2019: The WTP Scrubber Replacement quote submissions were opened on March 4, 2019. Integrity Municipal Systems was awarded the work and will begin the rehabilitation effort on April 22, 2019. Rehabilitation will include a pump replacement, replacing belts and seals, and replenishing the chemical that treats the chlorine if a release were to occur.
April 22, 2019: Work on the WTP Scrubber Replacement is underway.
May 10, 2019: The chlorine scrubber rehabilitation and testing is complete. This system provides protection to employees and the public during an emergency chlorine spill.
