Safe Drinking Water Advisories
New Orleans: A precautionary BWA has been issued following a loss of water pressure in the distribution lines, impacting:
- Florida Avenue from Inner Harbor Navigation Canal to the Parish line
- Parish line from Florida Avenue to the Mississippi River
- The Mississippi River from the Parish line to the Inner Harbor Navigation Canal
- Inner Harbor Navigation Canal from the Mississippi River to Florida Avenue
Water pressure has been restored, the impacted areas are to boil water intended for consumption and hygiene for at least one minute. Water testing will indicate when the BWA can be removed.
