A boil advisory is likely to remain in effect for Maryville until Thursday morning.

The city issued a boil advisory Monday evening due to a ruptured water line at the city water plant.

The ruptured line caused the water system to lose pressure.  Repairs were made, and workers were re-pressurizing the water system Monday evening.

The advisory is a precautionary measure as city officials cannot guarantee the safety of water due to potential back-siphoning occurring.

The city has advised residents to boil water used for consumption while the until the advisory is lifted.
