Cochran Engineering has presented a contract to the Union personnel, finance and public works committee for three sewer projects.
The city has targeted three sanitary sewer projects it would like to address in the 2018-19 budget year.
Cochran said for a total of $27,900 the city can get a topographic survey and a design of all three projects.
The deal was approved at the Monday, Aug. 13, board of aldermen meeting.
Earlier this year, the city entered into a deal with Cochran to research three possible projects around Union. At the Aug. 6 meeting, Cochran presented a proposal for the design and study of the work.
The committee agreed to support the proposal and move it forward. The board of aldermen will vote to approve the contract at a future 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.
The first project is the realignment of the Christina Avenue sewer line. The project involves approximately 610 feetof new gravity sewer line.
Union City Engineer Jonathan 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 second project is 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.
Because the project involves railroad lines, Zimmermann said it’s not a simple project.
“There’s an existing lift station that we want to take offline,” he said. “What we want to know is, can we get gravity lines to it. The problem is, there’s a right of way issue with the railroad. Before we get too far into the project, we want to make sure we have the ability to do it. (Cochran) is going to put together a conceptual plan, with costs, so we know if we can do it and, if we can, how much it’s going to cost.”
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.
“We had a sewer fail and we were able to temporarily bypass it and go to a second clay sewer line that was underneath the building,” Zimmermann said. “To solve the problem, we’re going to run down and connect it along Highway 50, but there’s a big storm sewer in the way. We want to be sure we can get around that and get a route that works.”
Money is allocated in the 2018-19 budget for all three projects. The city intends to do some of the work in-house.
