City commission looks at wastewater management project
POLSON — Polson City Engineer Shari Johnson presented information on the wastewater management system at the Polson City Commissioner’s Nov. 3 meeting. In May commissioners selected a membrane type of treatment system, according to their informational PowerPoint presentation.
In a phone interview later, Polson Mayor Heather Knutson said the commission wanted to find out if the project could be extended.
There are a couple of options for extension, Knutson said, but the City of Polson is not currently meeting EPA standards.
When the commission originally made the decision to go with a membrane system for the wastewater treatment system, they were operating on the information they had. Johnson presented additional information at the Nov. 3 meeting, according to Knutson, and the commission will vote on the issue at the Nov. 17 meeting.
City crews will be emptying the existing lagoon cell between now and March 2015, and equipment and sludge removal will commence in February 2015. Plans call for a complete geotechnical investigation to be completed by April 2015.
The short-term schedule for construction calls for equipment procurement by March 2015, including headworks screens grit removal systems and finding a membrane bioreactor manufacturer.
In the long term, the wastewater treatment project will initiate a design in April 2015. With a preliminary design completed between June and October 2015 and the final design approved sometime between November 2015 and March 2016.
Plans are to advertise for bids in June 2016, award contracts in July 2016 and then construction on the project, lasting for a minimum of 18 months, with the project completed in April 2018.
Commissioners appointed Lisa Kinyon to the Polson Redevelopment Agency.
In other business, the commissioner approved a proposal by McCrumb Construction and Marine Inc. to install three streetlights on the path from Sacajawea Park to Riverside Park.
Since there wasn’t money in the budget for the lights, Erika and Ben Binger of BenErika LLC agreed to donate funds to the park lighting fund to complete the project. The three lights will go in front of the Salish building on the walkway.
The next commission meeting will be held Nov. 17 at 7 p.m. in council chambers.
