NEW ORLEANS – On Tuesday, the Sewerage and Water Board of New Orleans (SWBNO) announced a comprehensive 5-year drainage system inspection plan that will provide a complete condition survey of the SWBNO portion of the New Orleans drainage system. The results of the condition survey will guide the strategic development of a yearly drainage maintenance plan.
SWBNO is responsible for all closed and open canals that are 36 inches in diameter and greater in size. With approximately 210 miles of closed canals and 65 miles of open canals, the inspection plan will access all SWBNO drain lines every five years.
“This is a massive undertaking and a critical step in working to learn everything we don’t know about our infrastructure,” said Ghassan Korban, Executive Director, SWBNO. “There are no records of an inspection of this magnitude ever happening before. We know that historically, our critical infrastructure was not well maintained. As we work to implement these inspections, we remain committed to remedying any issues we encounter in our canals as funding allows. We hope this shows the public that under new leadership, we are doing things differently.”
The inspections will be divided into five geographical areas, starting with the oldest drainage structures. Residents can expect to see minimal impacts to traffic patterns with temporary one lane closures or one lane shifts for traffic control during drainage system access. This inspection work will have no impact on customers’ water service.
