Coon Rapids watermain lining project set for this year

The city of Coon Rapids first used watermain lining last year to fix a continuing water break problem on Xeon Street, south of 121st Avenue.

It was so successful that Public Service Director Steve Gatlin recommended to the Coon Rapids City Council that another watermain relining project be done in 2012.

The council has accepted a proposal for engineering services for watermain lining on 93th Avenue and Evergreen Boulevard.

According to Gatlin, the work on Xeon was done as a demonstration to explore new technology for lining watermains similar to the lining projects done the past several years on the city’s sanitary sewer system.

“The project was very successful and allowed the watermain to be relined rather than excavated and replaced,” Gatlin said.

“Staff wishes to continue with the watermain lining program similar to the sanitary sewer lining program.”

Specifically, the plastic lining would be done on other sections of watermain in the city where there are maintenance issues, Gatlin said.

“We have had several watermain breaks on 93rd Avenue and Evergreen Boulevard,” he said.

That has been due to the corrosive soils in the area and the problem would be eliminated with the plastic lining, which would not be affected by the soils, according to Gatlin.

The proposed lining project includes 93rd from Coon Rapids to Evergreen boulevard and Evergreen from 93rd Avenue to 93rd Lane.

While the watermain living construction is in progress, the city will provide temporary water service to businesses in the area.

The city’s timetable calls for the project to be bid in the spring, with constructing starting in May 2012 and completion by July.

Estimated construction cost is $506,000, which will be paid for out of the city’s water utility fund.

The SEH agreement for the engineering, bidding and construction inspection services has a $97,104 price tag, with the money also coming from the water utility fund.
