Committee members discuss corroded pump-house wet well, interim fixes and costs

Staff members and meeting participants described a corroded wet well beneath the facility’s pump house that has allowed sediment and lake material to enter the pumps, reducing system capacity and prompting consideration of interim repairs or full replacement.

"Contractors replaced the pipe going out into Crystal Lake," said the Staff member, who reported that crews found the original corrugated steel pipe and corrugated-steel wet well badly corroded beneath the pump house. He said sediment has been scooped out manually and continues to enter where the new pipe connects, compromising the wet well’s ability to deliver clear water to the pumps.

The staff presentation laid out three main options: attempt a cement lining of the existing wet well; remove the roof above the wet well and install an internal plastic sleeve; or build a new pump house adjacent to the existing structure. The sleeve option would reduce internal diameter (staff said a 48-inch wet well would have to accept a 42-inch external sleeve, with a roughly 40-inch internal diameter), which staff warned could reduce pump capacity. "It's close to its end of life expectancy," the Staff member said of the existing pump house.

Participants discussed cost trade-offs. The Staff member recalled a pre‑COVID estimate for a new pump house of about $305,000 and suggested a current estimate might be nearer $500,000; he also said interim fixes would cost substantially less in the near term (mentioning roughly $75,000 of spending to extend life for several years). The group discussed bonding a new pump house over 10 years as a financing option.

The meeting included a review of financials: a participant reported revenues of $711,000 and an expense figure transcribed as "$6.93" (the speaker said the expenses included newly purchased equipment). The transcript also references an $18,000 number that the speaker said was likely to change as the season progresses; the exact breakdown of expenses was not specified in the record.

Later in the meeting, a participant said, "I'll second," and the Chair called for a voice vote: "All in favor, say aye." The assembly responded, "Aye." The transcript does not record the precise text of the motion that was seconded or a roll-call tally; it records only the second and the affirmative voice vote.

Participants closed by setting follow-up dates. They discussed a possible special meeting next week (contingent on availability of a member referred to as Vinny) and agreed to meeting dates including May 11 and June 1, with May 15 or 19 offered as alternatives.

Next steps identified in the discussion included meeting with a second contractor to seek a permanent fix, getting updated cost quotes for a new pump house and for lining versus replacement, and scheduling a follow-up meeting to consider those estimates.
