Council authorizes up to $30,000 for sewer root-control treatment through BuyBoard cooperative
Summary
The council approved a contract authorization of up to $30,000 for root-control treatment of the sanitary sewer collection system using Duke's Root Control via the BuyBoard cooperative; staff said the treatment is a foaming agent and the program resumes a cyclical treatment last performed in 2021.
The council authorized city staff on Feb. 10 to contract for root-control treatment services for the sanitary sewer collection system through Duke's Root Control, using the BuyBoard cooperative, with a contract maximum not to exceed $30,000.
Public Works staff explained the city last used the chemical root treatment in 2021 and has multiple locations with known root intrusions in sanitary mains. The treatment described by staff is a foaming agent that expands to coat the interior perimeter of pipes and attack root growth; staff said it kills roots but does not fully eradicate the plant. The city had reduced cyclical treatment after 2021 because other higher-priority projects diverted funding; staff said the intent is to return to a cyclical program.
Staff requested authorization to proceed under BuyBoard pricing; staff presented a unit-price estimate and mapped mains for treatment. A motion to approve a contract not to exceed $30,000 was moved and passed; the transcript records affirmative roll-call responses from Hayes, Briggs and Lambert. The motion record in the excerpt does not list the mover's name.
Council members asked clarifying questions about chemicals used and previous large roots recovered from mains; staff confirmed the treatment is a foam and said they would provide additional details as requested. The contract will be executed through BuyBoard to take advantage of competitively bid cooperative pricing.
