[ARCHIVED] Sewer improvements in West Ashley near Glenn McConnell Pkwy at Magwood

Over the next six to eight weeks, a contractor for Charleston Water System will be re-lining a sewer main at the intersection of Glenn McConnell and Magwood Drive, through the Lowes Parking area and along Henry Tecklenburg Drive in West Ashley.

The work will not affect any customers’ sewer service. The contractor, Layne Inliner, will install a new pipe inside the existing main using a process called cured-in-place pipe (CIPP).

This pipe replacement method involves inserting a liner through an existing manhole and filling it with hot water, which causes it to harden into a solid pipe that will effectively line the original pipe. All work will take place at existing manholes. Thisconstruction method causes fewer impacts than the traditional method of open cutting a large deep trench and laying new pipe.

In order to maintain sewer service while the pipe is lined, a temporary bypass pipeline is required and will be placed along Glenn McConnell Parkway. In order to cross Charlie Hall Blvd., flow-through ramps will be placed across Charlie Hall near Glenn McConnell. The ramps will be similar to speed humps.

The bypass pipe is made of thick, fused plastic and will be secured in place. An inspector will check the entire length of the pipe several times daily.

This sewer line work is part of a larger project to identify and replace sections of deteriorating sewer main in the Church Creek area.

For questions about this project, please contact Frank Frazier, CWS Project Inspector, at 843-296-2243 or email
