Town staff report pump and VFD problems; $214,000 repair estimate prompts talk of rate increases
Summary
Staff reported mechanical and configuration problems at pump stations, citing incorrect VFDs and plumbing that cause pumps to 'deadhead' each other; a repiping and motor/VFD replacement estimate of about $214,000 led to discussion that utility rates may eventually need a 10% increase to maintain solvency.
Town staff told the Select Board that recurring pump station failures and improper variable-frequency drives (VFDs) are causing frequent callouts and accelerated wear on pumps, and that the configuration prevents pumps from operating together efficiently.
A staff member described how the current plumbing and drives cause pumps to 'deadhead' each other when both operate, increasing RPMs and wear and tear. The town received a price estimate of roughly $214,000 to re-plumb, install new motors and correct VFDs; staff said that amount cannot be done at once and proposed staging the work over multiple years.
Board members discussed the prospect of increasing sewer rates to keep the system solvent; staff noted an initial planning estimate of a 10% rate increase but did not present a final proposal or vote. The board asked staff to compile cost details and timelines for a future agenda item on rates.
