A contract for infrastructure that could set the stage for recycled wastewater use in Manteca as well as open up nearly 120 acres for a waterpark resort and family entertainment zone could be awarded Tuesday night by the Manteca City Council.And the chances are the decision will spark an exchange between the low bidder — Knife River Constriction of Stockton — and city officials.Knife River submitted the lowest bid of $10,472,820 among six firms vying for the contract.Four days after the bids were opened on May 2, Knife River asked that they be allowed to withdraw their bid noting “we have identified errors in the preparation of our bid.” The city’s attorney office, however, is advising the council to reject the request by Knife River and award the contract when they meet Tuesday at 7 p.m. at the Civic Center, 1001 W. Center St.The five other bids were all at least $2.9 million higher. They ranged from $13,309,550 from Monzingo Construction of Oakdale to $15,631,000 from Sierra Mountain Construction of Sonora.The work involves infrastructure on 210 acres the city owns between Costco and Big League Dreams, the 120 Bypass, McKinley Avenue, and the wastewater treatment plant.
