Council approves $350,665 sewer‑lining contract to preserve aging clay mains

The Brighton City Council voted to award a sanitary sewer main lining contract to Insituform Technologies for a project estimated not to exceed $350,665, city staff said on Nov. 25.

DPS Director Brooks told council the target locations — Robertson Drive, Brighton Lake Road and South 3rd Street — contain clay sewer mains dating from the late 1930s that would benefit from lining rather than full replacement. He described the work and schedule and noted some traffic‑sensitive sections (Brighton Lake Road, 3rd Street) and higher‑flow lines would require nighttime operations: "Some of the work would have to be conducted at night, because of high flows in the sewer lines or traffic," Brooks said. Staff estimated about one‑third of the project could require nighttime work.

Brooks explained the project cost of roughly $304,926 for the proposal plus a 15% contingency resulted in the $350,665 figure, which exceeds the CIP budgeted amount by about $100,000. He proposed using $110,000 in savings from a recently completed grit‑room force main project to cover the overage. Council members asked about noise, duration of service disruptions, and alternatives; staff said lining is far less disruptive and far less expensive than full open‑cut replacement.

Motion: Council member Gibson moved to approve the Insituform contract not to exceed $350,665 with necessary budget adjustments. The motion was seconded and passed by voice vote.

Next steps: staff will prepare resident notices for affected homes (short interruptions to sewer service during work), schedule night shifts for high‑flow sections, and include the lining work in spring construction planning.
