City makes announcement via Facebook
UPDATE: June 22, 2021 at 10 AM – Adds city lifting advisory for area.
MANDEVILLE — A boil-water advisory that had been issued to a small area of Old Mandeville Friday (June 18, 2021) has been rescinded by the City of Mandeville, according to a post made to the official Facebook account.
The boil-water advisory had to remain in effect until today because the Louisiana Department of Health and Hospitals won’t accept testing samples on Fridays or weekends, and there’s a 24-hour turnaround on those results.
The city issued the boil-water advisory to a limited area south of Florida Street (U.S. Highway 190) after a water main ruptured Thursday night (June 17, 2021), forcing workers to effect repairs, according to reports and a release by the city.
The precautionary boil-water advisory was in effect for an area between Jackson Avenue on the west to the east side of Atalin Street, and between Madison Street north to Villere Street. (See map.)
The main ruptured near the intersection of Monroe and Atalin streets, filling a ditch with rushing water while city workers repaired the damage.
