For Immediate Release: Wednesday, November 2, 2022 12:20 PM

NEW ORLEANS — Sewerage and Water Board of New Orleans (SWBNO) contractor BLD Services, CMG Pipelines Inc. and Murphy Pipeline have will implement street closures from Napoleon Ave to Audubon St. over the coming months. The closures are necessary to accommodate waterline installation work as part of the S. Claiborne Transmission Main construction project. Signage and traffic control measures such as barrels and fencing are on onsite to direct drivers and pedestrians. 

We appreciate your patience as we upgrade your water system.

Transmission Main Projects

The replacement of the water main on S. Claiborne is a large Transmission Main (project name TM003) that SWBNO has replaced since 2018. There are 6 future transmission main projects scheduled and an additional 5 projects are currently underway. These projects are needed to proactively replace water lines as part of SWBNO’s commitment to infrastructure resiliency and reliability, as outlined in our five-year strategic plan.
