TDW repairs aging sewage main, service continues uninterrupted

Dec. 8, 2014

NEW CASTLE, Del. — A supplier of concrete and steel pipe systems turned to T.D. Williamson (TDW), a global pipeline service provider, to help repair an aging sewage line in Baltimore, Maryland.

NEW CASTLE, Del. — In the summer of 2014, a major supplier of concrete and steel pipe systems in the U.S. was confronted with the task of repairing an aging sewage line located in Baltimore, Maryland, according to a press release.

The company turned to T.D. Williamson (TDW), a global pipeline service provider, to help with the task by means of tapping the 54-inch sewage main and line isolation, allowing sewage services to continue uninterrupted, stated the release.

The release reported that the pipe system supplier planned to install a tandem 54-inch line stop on the sewage force main and a 42-inch bypass stop; to help ensure the existing sewage main continued to work during the task, a section of the pipeline was isolated and then covered in concrete, so it would properly support the equipment necessary for the tap and bypass.

TDW inserted folding STOPPLE® plugging heads into the line to stop the flow, and a manifold, constructed of three 24-inch lines, was connected, permitting the sewage to be diverted to another treatment plant using the bypass tap, continued the release.

“Our customer needed a dependable solution with minimal impact on the city’s services,” said TDW Project Manager Donnie Cecil. “We were pleased to be able to fulfill that requirement to their satisfaction.”

TDW provides a comprehensive portfolio of safe integrity pipeline system solutions for offshore and onshore applications, including hot tapping and plugging, integrity inspection, pipeline cleaning, pigging and non-tethered plugging technology for pressurized piping systems, noted the release.
