One of three sewer projects is out to bid.
The city has targeted three sanitary sewer projects it would like to address in the 2018-19 budget year. One of those projects, the Christina Avenue and Water Street realignment, went out to bid this week.
Bidding documents could be picked up Wednesday, Sept. 5. Sealed bids are due Tuesday, Sept. 25.
The bidding invitation states the city hopes the project will start in October.
The project includes the construction of approximately 600 lineal feet of PVC gravity sanitary sewer, associated manholes, site restoration and other incidental items.
The engineering firm Cochran, Union, is working with the city on the project. The city recently awarded a $27,900 contract to Cochran for topographic survey and a design of three projects.
The deal was approved at the Aug. 13 board of aldermen meeting. Under the deal, Cochran will perform a topographic survey in the area for $3,380. The rest of the money will be used toward creating the projects.
Cochran will design the projects, prepare plans for bidding and provide cost estimates to the city.
Union City Engineer Jonathan Zimmermann said the first project is the Christina Avenue and Water Street realignment. Zimmermann told The Missourian in April the work is tied into the bridge replacement slated for next year.
“Before we do the bridge, I want to replace that sewer line,” he said. “To do that, I have to get from good sewer to good sewer and I don’t necessarily know where that is.”
Zimmermann said the project won’t work if there are only “bad” sewer lines around.
“Bad sewer line — it’s a failed sewer,” he said. “When I say bad, most of them, it’s a clay pipe that has a tendency to fracture.”
The other two projects being worked on by Cochran are not included in the bid announcement.
Cochran also is working the Woodland Oak sewer extension. Cochran will be designing approximately 1,150 feet of new gravity sanitary sewer.
The project, if successful, will take the Forest Lane lift station offline. Zimmermann said the plan is to eliminate the lift station by extending the Woodland Oaks gravity line.
The third project addresses another “bad” sewer line. The city wants to reroute a gravity sewer line behind a Mobil gas station along Highway 50.
The project involves the design of approximately 250 feet of new gravity sanitary sewer.
Money is allocated in the 2018-19 budget for all three projects. The city intends to do some of the work in-house.
