In New Orleans, plumbing permits are issued by the Sewerage and Water Board of New Orleans (SWBNO), and a licensed master plumber registered with SWBNO must file the permit for installing, altering or repairing plumbing connected to the public water and sewer system.

Check your address for a lead service line
SWBNO keeps a map-based service line inventory that labels lines as verified lead, verified non-lead, galvanized, unknown, or assumed lead or non-lead. SWBNO owns the line from the water main to the meter, and the customer owns the line from the meter to the building. As of September 2026, SWBNO says it intends to replace lead lines at no cost to customers but that the program is not fully funded, and it offers free lead test kits and filter pitchers; check its Lead Awareness page for current status.

During a SWBNO boil water advisory, bring water to a rolling boil for at least one minute before drinking or cooking with it. Once the advisory is lifted, SWBNO says to run all cold water faucets for at least five minutes, throw out three batches of ice from ice makers, and drain and refill water heaters set below 113 degrees Fahrenheit.
