(KSDK) - High heat likely played a role in a water main break in west St. Louis County Sunday afternoon.
It happened beneath Manchester Road west of Mason, right at the intersection of Manchester Meadows. That's where Home Depot is located. Missouri-American Water Company officials say it is a 12-inch main that broke.
And they say as pipes go-- that's a large one.
As a result, area businesses may experience a decrease in water pressure.
Traffic on westbound Manchester Road is being diverted around the break right at Manchester Meadows. Missouri-American Water Company officials say prolonged heat causes the ground to shift. That, combined with increased pressure inside the pipe due to high demand makes these pipes vulnerable.
Missouri-American officials say they will be narrowing Manchester Road down to a total of 2 or 3 lanes to fix the pipe and repair the road. At 4:20 p.m. Sunday, Missouri-American Water officials said they hope to have the water on by about 7:00 p.m., and hope to begin re-opening traffic lanes by about 10:30 p.m.
