Charleston to Update Sewer Lines in Corridor G Area

Article excerpt

The Charleston Sanitary Board is overseeing its next capital improvement project to update the city's aging sewer lines in the Corridor G and Southridge areas. The Hickory Hollow Sewer Replacement and Kimberly Road/Oakhurst Drive area Sewer Rehabilitation projects have a combined $1.7 million price tag.

The work is being paid for internally by the sanitary board, said Operations Manager Tim Haapala, rather than through low-interest loans or bonds.

"The first step is clearing the right-of-way and pulling the [trees] and stumps out to be able to dig and put the pipeline in, Haapala said.

The existing vitrified clay pipes will be replaced with plastic polyvinyl chloride (PVC) pipes.

The Hickory Hollow project will install 6,400 feet of new pipe, ranging from 10 to 18 inches in diameter.

Another 2,300 feet of specialized pipe liner will be installed in areas where the existing pipe is intact.

Fifty new manhole structures will be added along the new line, Haapala said.

Work on the new line will begin at the low point, near Corridor G, and work its way uphill.
