2021 Project of the Year Rehabilitation Winner: ‘The Mess’ Emergency Gas System Repair in South Orange, New Jersey
|
|
In early 2020 in South Orange, New Jersey, when it was discovered that there was a leak in the Public Service Electric and Gas Co. (PSE&G) line running in an easement adjacent to the ever-busy South Orange Avenue and the East Branch of the Rahway River. The project team affectionately dubbed this section “The Mess” because it resembled a “tangled knotted ball of yarn.” It is because of these technical complexities and the ingenuity and technical advancements necessary to complete this job that it was chosen as the 2021 Trenchless Technology Project of the Year for Rehabilitation.
