Upgrades to St. Tammany Parish water system will require a boil-water advisory order to be issued Wednesday (March 20) for homes and businesses off Ben Thomas Road in the Slidell area, St. Tammany Parish government said in a news release. Work will begin at 9 a.m. Wednesday to install a flow meter and check valve on the Ben Thomas water well storage tank, the parish said. There are 80-to 85 homes in the affected area, the parish said. Customers might lose water pressure and state health regulations require the parish to issue the precautionary boil-water advisory. During the boil advisory, water should be boiled for at least one minute before consuming it. That includes water for brushing teeth and food preparation. The advisory will be lifted after water samples tested are cleared by the state Department of Health. Area residents will be notified by automated calls, signs and notices on parish social media sites when the boil order has been rescinded, the parish said. The parish notice said anyone with questions can call Tammany Utilities at (985) 276-6400. The state of St. Tammany Parish?
