One way proposed to try to solve the ongoing infiltration problem with the Tama sanitary sewer system is a process called "slip-lining."
It involves installing a fiberglass shell and plastic pipe within the existing lines. This prohibits ground water from entering existing broken pipes. Most notably, slip-lining has been done successfully on portions of the line which serves the residential area of North McClellan Street.
John Lloyd, Tama Public Works director, told the Tama City Council at their Sept. 4 meeting the city's sewer treatment plant was handling more waste than the city pumps out in water on a daily basis.

Lloyd was instructed to provide details of the slip-lining proposal.
On Monday night, Sept. 17, he told the council the area of the city, primarily south of 13th Street has a total of 13.94 miles of sewer lines. The estimated total cost to slip line this portion of the system and to repair up to 282 manholes in the same area was put at $1,946,451.
A survey of city residents income conducted earlier this year found Tama would qualify for a Community Development Block Grant of up to $600,000 to pay for such a project.
Lloyd said Monday if the city applied and was awarded a CDB grant, the cost of a project split would be 70 percent Tama and 30 percent grant money.
Council member Steve Baier questioned if lines north of the 13th Street dividing line were in good condition. Lloyd said he believed they were because of being on higher ground.
He did say the city could face another line problem along U.S. 63 (North Harding Street) from about 15th Street to 13th Street, however.
In a related water department matter, Lloyd reported water main breaks which were losing an estimated 300,000 gallons of water daily had been located and repaired. The repair of the first two breaks did not solve the loss. A third break located along L Avenue south of Kruger Commodities and across the road from Iowa Premium Beef was the largest culprit.
It was located on Friday and the line was shut off. It currently serves water customers Lloyd said.
Lloyd said if future demands all for the water line to be put back in service, he would propose drilling under L Avenue and rerouting the line to the east side of the roadway.
In other business Monday the council:

City participation made the school district eligible for a grant for the project.
