The Sewerage & Water Board has issued a boil-water advisory for English Turn and the Lower Coast area of Algiers after a 12-inch water main ruptured during Sunday afternoon’s storm, leading to fears of low pressure in the water system in those areas.

Residents in the affected areas should boil tap water for a full minute before drinking it or using it for making ice, brushing teeth, showering or bathing, officials said.

The water main, in the forebay of the U.S. Army Corps of Engineers-managed Algiers Lock, was closed after it ruptured. Crews worked through the night to try to fix the problem and raise pressure in that area of the system above 15 pounds per square inch, the minimum amount required by public health officials, but they were unable to do so, according to the S&WB.

Although the pressure was never measured below 15 pounds, it was considered too close to that figure for comfort, so the boil-water advisory was issued, officials said.

The agency is taking steps to increase the water pressure and minimize health risks, a spokesman said.

Once the system is repressurized, the S&WB and the state Department of Health and Hospitals will test water samples before the advisory can be lifted.

Residents with questions should call (504) 529-2837.
