Authority approves force‑main flushing automation and contingency purchase for lift‑station equipment
Summary
Board approved a one‑time SCADA/software modification to enable programmable flushing of a 30‑inch force main and approved a replacement sampler booster pump contingent on demonstration of warranty; staff also tabled a preventive maintenance program for later negotiation.
The board approved two operations items affecting lift‑station performance and maintenance.
First, staff presented a contractor quote to add a programmable flushing interface for the 30‑inch force main so city operators can schedule and vary flush durations and volumes remotely. Staff said the approach is a one‑time configuration and interface (using the existing HMI) that would allow trial‑and‑error adjustment without recurring vendor fees. Staff recorded the packet cost for the force‑main flushing program modification at approximately $13,680 and the board approved the work.
Second, operations requested approval to replace a failing sampler booster pump at the main lift station; the replacement quote was $3,781. The board approved the purchase but made the approval contingent on confirmation of a warranty period for the replacement unit.
Staff also presented a preventive maintenance program (from Roadtorque) to perform periodic inspections and partial internal work on check valves and force‑main components. Board members expressed concern about warranty overlap and wanting to avoid paying for coverage while new equipment is still under warranty; the board tabled final approval and asked staff to renegotiate payment term dates and warranty alignment.
Next steps: staff will proceed with the force‑main flashing program configuration, confirm warranty terms for the booster pump replacement and return with recommended preventive maintenance terms.
