An Ace Pipe Cleaning crew in 2020 feeds PVC liner as it is pulled through a manhole and sewer main.

8,500 feet of sewer main to be lined this summer

Lining keeps zinc-laden ground water from entering sewer system through old pipe

At the other end of the line, an inflated liner is cured with steam. Once cured, the excess liner is cut off inside the manhole.

A total 8,500 feet of 8-inch sewer main will be lined this summer by Ace Pipe Cleaning at a cost of $238,000. The contract was approved Monday by the Webb City Council.

The lining process, referred to as CIPP (cured in place PVC), is a liner pulled through a sewer main (after it’s cleaned) and then expanded and cured with steam. Once installed, the liner keeps ground water from entering the sewer system through breaks and cracks in the original sewer line.

CIPP requires no digging. The liner is pulled from manhole to manhole

During periods of heavy rain, ground water overwhelms the sewer system, requiring the excess to be diverted to a lagoon before eventually being treated. The main problem is that ground water picks up zinc, which can’t be removed during the treatment process and is harmful to Center Creek.

Webb City is piggybacking on Joplin’s bid process, which resulted in a $28-per-foot price from Ace Pipe. Ace’s contract with Webb City includes an $8,000 mobilization fee.

The project will be conducted in two phases, with the first 2,200 feet to be installed now, and the remaining 6,300 feet to be installed starting in August.

Ace Pipe has done a lot of work in Webb City, including previous sewer lining projects. In fact, $300,000 was spent on a similar project last year.

The Center Creek 201 Wastewater Treatment Plant’s operating permit with the Missouri Department of Natural Resources stipulates that Webb City, Carterville and Oronogo continue efforts to reduce the amount of zinc that is released into Center Creek.

The following five maps show which sewer mains will be lined this year.

 

Also, a bill to vacate a never-used alley north of Webster Primary Center was accepted on first reading. The property the alley was planned to go through, is on the west side of Main Street between Aylor Street and Stadium Drive. It is the site of the new American Legion building.

City Administrator Carl Francis reported that bids are being obtained to clear two city-owned properties – the former G&H Redi Mix site and a wooded area east of the soccer fields in King Jack Park.

The city has already had the G&H buildings removed. Now it seeks to prepare the property for development. Francis says the property, at the east end of Broadway (Route 66) has gained value because of its proximity to East Street.

Clearing the unused property east of the soccer fields will allow another entrance (from Railroad Way) and parking to relieve congestion on the west side of the fields.
