Brainerd council asks staff for a 3'5year prioritized sewer-lining plan, citing age, site constraints and televising results
Summary
After a staff presentation on sanitary sewer main conditions and maps identifying older lines, the Brainerd committee directed staff to return with a prioritized three- to five-year lining plan that includes cost estimates and potential funding options.
The Brainerd City Safety and Public Works Committee directed staff to develop a prioritized three- to five-year plan for sanitary sewer main lining and return with funding options, after a staff presentation that stressed a multi-factor prioritization approach.
Jesse, presenting for Public Works, told the committee staff recommends ranking lining work using a combination of factors: pipe age, site constraints (for example mains running under buildings), and condition determined by televising. "Age isn't necessarily synonymous with poor condition," Jesse said, noting some 100-year-old lines still flow well while some 60-year-old lines are in poor condition.
On assessment methods, Councilman Chzik asked whether lines that cannot be televised should be treated as the worst cases. Jesse replied that inability to televise may reflect a sag or debris and is not always synonymous with complete failure, but added, "That's the best method we have right now. Yep."
Jesse provided preliminary scale and cost guidance: "At about $100,000 we're able to tackle about roughly four standard city blocks worth of length," and staff referenced a per-foot estimate in the $70 to $80 range before clarifying the figure as "$80 per foot." He also explained ownership for laterals: "They own the service line from the main ... that is their responsibility," and said the city will replace to the right-of-way for reconstruction projects but cannot mandate replacement of privately owned laterals.
Council members asked staff to return with a refined prioritized list for the next three to five years, cost estimates, and potential funding options (including the possibility of a rate increase). A motion requesting that staff come back with that recommendation, consistent with staff's prioritization criteria and including funding potential, was moved, seconded and approved by voice vote.
Staff said it can prepare a priority ranking based on the known problem areas and the agreed criteria for presentation at a future meeting.
