Council authorizes manhole replacement contract after inspection found hydrogen-sulfide damage
Summary
Council approved a contract with Bull G Construction for 24–27-inch sanitary sewer manhole replacements after staff reported hydrogen-sulfide corrosion in several manholes; five bids were opened and Bull G was the lowest qualified bidder.
Public Works Director Scott Christen told the council the city inspected sanitary sewer infrastructure along the lake frontage and found the main lines in good condition but multiple manholes showing corrosion from hydrogen sulfide, prompting a replacement project. "We did find that the sanitary sewer main itself is in good condition. However, due to hydrogen sulfide corrosion, several of the manholes have seen... corrosion, erosion that need to be replaced," Christen said.
The council heard that staff identified five bids and that Bull G Construction (listed on the bid tab) was the lowest qualified bidder. Council approved resolution 2026-3238 authorizing a construction contract for the 24–27-inch sanitary sewer manhole replacement project to prevent imminent failure and avoid a catastrophic event. The motion carried by voice vote; council asked staff to proceed with contracting and scheduling under the city’s procurement rules.
Christen described the replacement work as full excavation and removal of damaged manholes and installation of new concrete manholes using a concrete mix impregnated with a protective product (ConShield) to reduce future hydrogen-sulfide deterioration.
