St. Clair officials hope the water leak underneath Highway 30 at Springfield Road will be fixed before summer hits.
Public Works Director Jason Ivie told The Missourian last week that he currently is working on getting engineering proposals from area companies to see what needs to be done and how the city can best do it.
“We’re trying to get ideas on how best to fix it and get the best value on the dollar,” Ivie said. “Hopefully, we will figure out soon where we need to go with this.
“A realistic time frame should be to have it fixed sometime this spring.”
The leak first was noticed in January. The Highway 30 pavement at Springfield Road constantly is wet as water leaks from the line underneath.
“We think the pipe may have broken,” Ivie said. “It’s possible the problem is in a valve or joint, but most likely it’s a break. We really don’t know for sure, and we may never know.”
The leak, which Ivie described as “minimal” and “pretty slow,” is in the 4-inch water main that runs under Highway 30. It is connected to new 10-inch lines on both sides of Springfield Road that were installed as part of that street’s major overhaul last year.
“There used to be 4-inch lines running along Springfield,” Ivie said. “When the street was redone, we put in 10-inch lines on both ends (East and West).”
Ivie said employees from Missouri Rural Water inspected the situation in February and March and determined the problem was in the line under the highway that connects to the Springfield mains. There was some thought that the trouble was in the water line that runs along South Lay Street, but that ended up not being the case.
The new, larger lines on each side of Highway 30 were connected to the old, 4-inch line that runs under the highway. The Missouri Department of Transportation would not allow the city to close that thoroughfare and tear it up to replace the water line underneath it.
That means that 10-inch water lines run along both East and West Springfield Road, but they are connected to the 4-inch main under Highway 30.
Now, the city probably will have to bore under Highway 30 and lay a new, 10-inch line there and connect it to the Springfield Road lines, Ivie said.
Another option still calls for the boring under the highway, but the new line there could be connected to an 8-inch main that runs near Highway PP. For that option to work, new water lines would have to run parallel on both sides along Highway 30 to Springfield.
Ivie said there could be some utility issues with that plan.
“We will do what is best to fix the leak,” Ivie said. “We will price it out to see what is financially better, but we will get it taken care of.”
There are no estimates as to what the repairs may cost the city.
The board of aldermen will be advised of the situation as well as given updates when they become available.
Once engineering proposals are secured and the best way to fix the leak is determined, the city will seek bids for the project.
