SWBNO is committed to providing safe drinking water, and this precautionary boil water advisory was issued out of an abundance of caution to ensure the public’s safety. We thank the impacted residents and businesses for their patience and apologize for any inconvenience this may have caused. We also commend the fast and professional work of SWBNO employees from several departments and the excellent cooperation of LDH officials during this event.Boil water advisories are issued out of an abundance whenever the water pressure drops below 20 psi. We agree with the recommendations of our regulatory partner, LDH, that it is prudent to issue these advisories. This precautionary boil water advisory was issued on Aug. 16 when water pressure levels dropped below 20 psi due to a struck hydrant.Customers in other areas of the city were not affected and did not need to boil their water. Water service has been restored to affected customers after a vehicle struck a fire hydrant on Chef Menteur Highway. SWBNO, in partnership with the Louisiana Department of Health, issues boil water advisories out of an abundance of caution for areas where water pressure drops below 20 pounds per square inch (psi). The concern is that a pressure drop inside a water pipe could allow bacteriological contaminants to enter.
