The Division of Water Treatment presented an item to replace wooden stop logs at spent‑lime lagoons with engineered aluminum stop logs that provide improved sealing and a longer lifecycle.

Officials explained spent lime from the treatment process is stored in lagoons to dewater. Wooden boards previously used to retain water are subject to failure, which can cause unintended discharges to permitted streams and complicate MPDES‑permitted outfall reporting. The engineered aluminum logs are intended to reduce the risk of failures and provide better sealing.

Councilmember Martinez recommended the item be advanced (SEP). The administration characterized the purchase as a modernization to reduce operational failure risks; the transcript does not record a formal vote during the meeting.
