Commission considers piggyback contract for cured‑in‑place sewer lining and CCTV van upgrades
Summary
Staff recommended piggybacking off a larger county contract for cured‑in‑place sewer lining to avoid mobilization fees and proposed upgrading the CCTV ‘Ques’ van; commissioners discussed environmental disposal and prioritized small‑linear‑foot repairs.
To extend the life of deteriorating sewer mains without large-scale excavation, staff proposed using a piggyback arrangement with a vendor already contracted by a neighboring jurisdiction. The key advantage staff cited was the absence of mobilization fees and flexibility to execute small stretches (no onerous minimums).
"They offered to let us piggyback off their contract," staff explained, adding the approach reduces per‑foot costs and avoids the large mobilization expenses that made in‑house bids expensive for small segments. Commissioners asked about environmental disposal of cleaning residues and whether the city had used cured‑in‑place lining before; staff said the method is common elsewhere and that the CCTV (Ques) van upgrade will help prioritize problem locations.
Why it matters: the approach would give the city a cost-efficient way to extend pipe life by decades while minimizing road disruptions. Commissioners asked staff to confirm environmental safeguards and to provide cost comparisons before authorizing piggyback procurement.
