All United Water System customers are under a boil water advisory until further notice.
Officials say that the advisory is due to low water pressure caused by a malfunctioning valve at the plant.
Water samples will be taken and residents will be advised when water is safe to consume.
Residents should boil water for one full minute before consuming.
The United Water System covers portions of Cecilia, Breaux Bridge, Leonville, and Arnaudville.
