Port authorizes bidding for Imperial Way sewer lining project using cured‑in‑place pipe
Summary
The board authorized staff to solicit bids to rehabilitate about 1,400 linear feet of sewer on Imperial Way using cured‑in‑place pipe (CIPP); staff estimated the project at $280,000 against a $423,320 budget and emphasized minimal digging and a roughly 10‑day installation window.
The Port of Bremerton board voted to authorize staff to call for bids to rehabilitate approximately 1,400 linear feet of sewer on Imperial Way using cured‑in‑place pipe (CIPP) technology.
Port staff described CIPP lining as a method that inserts a resin‑saturated fiberglass liner into the existing pipe, inflates and cures it to form a continuous, jointless pipe without open‑cut excavation. Staff said the lining carries an estimated lifespan of 50–100 years, requires minimal maintenance and would reduce downtime during installation to roughly 10 days for the full length.
Cost and budget: Staff said the work is part of a 2022 capital budget line; the project cost is currently estimated at $280,000 against a budgeted $423,320, leaving an anticipated remaining budget of approximately $143,000. Staff compared the CIPP estimate with an earlier open‑cut replacement estimate and noted substantial cost savings.
Operational details and scope: The project covers roughly 1,400 linear feet of 8‑inch pipe serving a cluster of industrial and marine businesses along Imperial Way (staff listed several businesses including SP Marine and Imperial Truck & RV). Staff said the port had inspected the line with cameras and found alignment issues at some joints but no major failures, and that contractors commonly perform inspection, cleaning (water‑jetting or mechanical root removal), lining and cure steps.
Board action: After technical questions about warranty, lining methods and the need to excavate if crews encounter a break, a commissioner moved to authorize staff to call for bids for CIPP sewer rehabilitation. The motion carried on a recorded vote.
What happens next: Staff recommended including a warranty requirement in the procurement and expects local competition among CIPP contractors to produce competitive bids; the port will return with bid results and a recommendation for award.
