Sanitary sewer work is scheduled to start after the Memorial Tournament in the Muirfield area, but impact to residents is expected to be minimal.

"There will be a lot of equipment on the road in the residential areas when they are doing the work on that particular street," said director of streets and utilities Ron Burns. "We aren't going to close any roads, but it will be a little noisy. There also may be a slight odor during the process."

Burns said he did not anticipate a total disruption of service, but it is possible residents will be asked to use as little water as possible over several hours. The city will notify residents in affected areas as the date approaches through letters, door hangers and the city's Web site, Burns said.

On May 19, Dublin City Council approved the $2.9-million contract with Reynolds Inliner to complete sanitary sewer work in the next three years.

The first phase, to start in about two weeks, will line the clay sanitary sewer pipe that was installed in the 1970s. Work should be completed by the end of November, Burns said.

Data collected by the city during its cleaning and inspections showed "significant inflow and infiltration and deteriorated pipe," according to a memo distributed to city council.

"When you talk about inflow you're talking about clear water that is getting into the sanitary sewers from things like sump pumps and gutters," Burns said. "Infiltration is clear water that leaks into the sanitary sewer pipe through groundwater that seeps through seams and cracks in the pipe."

The problems reduce the capacity of the sanitary sewers and add to the quantity of sewage the Columbus treatment plant has to handle, Burns said. It could also result in overflows in manholes along the sanitary sewer line.

The process of lining the pipe is expected to extend the life of the line by 30 to 50 years, saving the city money by not having to replace the entire pipe.

"This is by far the most efficient and economical method of renovating sanitary sewer lines and the really great thing is it rarely requires excavation," Burns said.

To line the pipe, a flexible fabric type of pipe is inserted into the sanitary sewer lines, expanded and cured with hot water or steam, resulting in a hard, plastic-like pipelining, Burns said.

The same type of work in the Muirfield area will be continued in 2009 over a period of four to six months, Burns said. A specific time has not been identified.

Work will be completed in 2010 on a 36-inch sanitary sewer along Dublin Road between Glick Road and Emerald Parkway.

The 36-inch main sanitary sewer pipe is concrete reinforced with steel bars, but hydrogen sulfide gas resulting from decomposition of sewage in the pipe has damaged the line, Burns said.

The installation of the liner is expected to stop the damage from occurring and strengthen the pipe by about 20 percent to extend its life by 30 to 50 years, according to the memo distributed to council.
