Authority approves programmable force-main flushing upgrade to reduce odors
Summary
The board approved a hardware/software upgrade to allow programmable flushing of a 30-inch force main; staff said the one-time programming and interface will let operations adjust flush frequency and timing to address odors and low-flow conditions.
Operations (S5) presented a quote from Poshgen Electric to add programmable flushing control to a 30-inch force main. The upgrade includes software configuration and an HMI interface that allows staff to set flush schedules, durations and volumes without recurring service fees.
Operations described the existing flushing regimen as once weekly for 6–8 hours and said that had not solved odor problems. The proposed system would allow more frequent, targeted flushing at late-night low-flow periods; staff described it as a one-time fee rather than a recurring annual charge. The board approved the program by motion and voice vote.
Staff said they will coordinate with vendors for implementation and provide operational guidance once the system is installed and tested. No further funding details were committed beyond the approved quote amount presented in the packet.
