ST. LOUIS COUNTY – Missouri American Water issued a reverse-911 call for a precautionary boil water advisory for a portion, not the entire municipality, of Crestwood and Sunset Hills in St. Louis County.

The customers in the affected area will be contacted via the reverse-911 call.

Customers in the affected area should bring their water to a boil for three minutes before using it for drinking or cooking. Tap water is okay for washing, bathing and other non-consumable uses.

This advisory was caused by a water main break at Watson Plaza Drive which led to a low-pressure event. About 5,500 customers are affected.

Boil advisories typically last 24-48 hours, though that timing cannot be guaranteed. Water quality tests will be run as soon as the broken main is repaired.
