Board approves $133,810.90 sanitary sewer repair contract after inspection finds multiple pipe fractures
Summary
Trustees unanimously approved a $133,810.90 contract with Western Iowa Utilities to repair seven pipe fractures, reline 18 manholes and correct a reverse-grade connection after staff described infiltration and flow problems.
District engineering staff told the board that investigations of the sanitary system that serves Titan Hill, the operations building and the middle school found seven fractured pipe sections, roughly 18 manholes with infiltration or poor seals, and a segment where the building connection drains in the wrong direction (negative fall). Staff said those defects introduce stormwater into the sanitary system and can contribute to interior backups.
The recommended repairs include reboring a new pipe under a roadway to establish correct fall, lining and sealing manholes with a centrifugal cast cementitious liner, setting two new manholes and excavating and repairing discrete pipe-break locations. Staff said much of the work is in roadways or grass areas rather than extensive interior demolition.
Two bids were received. Western Iowa Utilities — a local contractor with prior district work — submitted a low bid of approximately $133,810.90; a second, out‑of‑area bid was substantially higher at roughly $359,000. Staff recommended awarding the contract to Western Iowa Utilities as the qualified low bidder within the project budget.
At the June 1 action session the board moved and seconded the recommendation and voted unanimously to approve the Western Iowa Utilities contract for $133,810.90. The motion was recorded on the roll call with all members voting yes.
Staff noted there is no practical way to fully load-test the system except during severe storm events, but the contract includes camera inspections and visual verification; the project specifications may include backwater valves on pipes that could flow into buildings.
