The Water Division has not detected any contamination to the water supply and has issued the boil water advisory out of an abundance of caution.

ORIGINAL STORY
ST. LOUIS (KMOX) - The City of St. Louis was able to hold off issuing the boil water order, despite a power failure at the Chain of Rocks treatment facility during the height of Saturday afternoon's storms.
KMOX started receiving calls and emails from residents in and around the Tower Grove neighborhood about low water pressure. We confirmed with St. Louis Mayor Tishaura Jones' spokesman Nick Desideri what had happened, but he believed since not all power was lost, they were available to avoid the boil order.
From St. Louis City's website:
The City of St. Louis Water Division maintains two water treatment plants that draw water from the area's two main rivers. The Chain of Rocks Plant is located on the Mississippi River about eleven miles north of the center of the City and about five miles south of the confluence of the Missouri and Mississippi Rivers. The Howard Bend Treatment Facility is located on the Missouri River, 37 miles above the confluence of the Missouri and Mississippi Rivers and 15 miles west of the City limits. Combined, these two plants have the capacity to treat and distribute 380 million gallons of water per day (M.G.D.).
At 7:00 pm Saturday, Nick Desideri released the following statement:
During today’s storms, the City’s Chain of Rocks water treatment plant temporarily lost power, causing low water pressure in the neighborhoods surrounding Tower Grove Park. Ameren Missouri workers moved quickly to restore power, and the Water Division expects normal water pressure to resume shortly. There is no boil advisory at this time.
City residents are encouraged to report storm damage or continued low water pressure to the Citizens Service Bureau at 314.622.4800 or online. For power outages and downed wires, contact Ameren at 800.552.7583.
Residents have told KMOX water pressure remains low. We will continue monitoring the situation and post any updates as they are received.
