SWBNO's Algiers Water Treatment Plant is adding zinc orthophosphate, a food grade, EPA-approved corrosion control additive to drinking water beginning June 8th, 2026. This enhancement protects pipes from corrosion and reduces lead levels, reinforcing SWBNO's commitment to safe, high quality drinking water for all customers.

Sewerage and Water Board of New Orleans (SWBNO), in consultation with the Louisiana Department of Health (LDH), has canceled the precautionary boil water advisory for a portion of New Orleans East.

Hayne Blvd from Paris Rd to Vanderkloot Ave
Paris Rd from Hayne Blvd to I-10 Service Rd
I-10 Service Rd from Paris Rd to Bundy Rd
Bundy Rd/Vanderkloot Ave from I-10 Service Rd to Hayne Blvd
Entire Oak Island Subdivision

Water pressures in this area fell below 20 pounds per square inch (psi) due to a watermain break that is impacting a large part of the neighborhood.

Customers who have not used their water supply during this precautionary boil water advisory are advised to flush their internal and external plumbing by running water through their system for several minutes.

We recognize that the recent turbidity notifications contained incorrect names and addresses. The purpose of the notifications were to inform customers of the turbidity exceedance. We apologize for the recipient information error.

We are required to monitor your drinking water for turbidity (cloudiness) on a continuous basis (every 15 minutes) and report such results to the Louisiana Department of Health (LDH). This tells us whether we are effectively filtering the water supply. The Surface Water Treatment Rule (SWTR) requires our treated water to meet 0.349 Nephelometric Treatment Units (NTUs) or less in 95 percent of the measurements per month and never exceed a maximum allowable turbidity limit of 1.499 NTUs at any time.

During the April 2026 compliance monitoring period, the New Orleans Carrollton Water Works was in violation of the Surface Water Treatment Rule. The violation occurred because the New Orleans Carrollton Water Works treated water turbidity level exceeded the maximum allowable limit of 1.49 Nephelometric Treatment Units (NTUs) on April 23, 2026, between 8:15 a.m, and 9:15 a.m.

What should I do?

There is nothing you need to do. You do not need to boil your water or take other corrective actions. If you have specific health concerns, consult your doctor. If you have a severely compromised immune system, have an infant, are pregnant, or are elderly, you may be at increased risk and should seek advice from your health care providers about drinking this water. General guidelines on ways to lessen the risk of infection by microbes are available from EPA’s Safe Drinking Water Hotline at 1-800-426-4791.

What does this mean?

Water quality samples collected in April throughout the distribution system did not indicate the presence of bacteria in the water. This is not an emergency. If it had been, you would have been notified within 24 hours.
