City Engineering | David Barth, P.E.
The City of Stillwater and the Stillwater Utilities Authority will be improving the City's Water Treatment Plant (WTP) and Raw Water Delivery System, which were built in the 1980's. The Raw Water Delivery System consists of the Kaw Reservoir, the Kaw Pump Station and the Kaw Pipeline.
In 2017, SUA authorized staff to retain an engineering firm to prepare a needs assessment for the WTP, which identified several areas for improvements and upgrades. The needed improvements were estimated to cost $70 million, leading staff to step back and consider all possible alternatives.
In June 2021, the SUA contracted with Carollo Engineers and Burns & McDonnell (as Construction Manager at Risk - CMAR) to define and cost out alternatives for improving the WTP and Raw Water Delivery System. During this project definition phase, the consultants and staff confirmed several improvements that need to be constructed now. The confirmed improvements include a caustic feed system, lime residuals handling, a recovered water pump station, a finished water pump station, and a cathodic protection system for the Kaw Pipeline.
The project will add resiliency to an aged WTP and Raw Water Delivery System.
June 7, 2021: SUA authorized staff to enter into an agreement with Carollo Engineers for design engineering services and Burns and McDonnell for Construction Manager at Risk (CMAR) services.
September 27, 2021: City staff and Carollo Engineers presented alternatives for improving the WTP, additional raw water storage, confirmed improvements, and next steps for the project.
