CHESTERFIELD, Mo. (AP) -- Crews from the Metropolitan St. Louis Sewer District are working to repair a break in an underground sewer that is allowing raw sewage to flow into the Missouri River at Chesterfield, Missouri.
"This is age," said Lance LeComb of MSD. "It's an example of aging infrastructure in an older urban area."
MSD officials said Monday that the break near Cordovan Commons Parkway was draining into a ditch that leads to the river.
"The condition of the drinking water coming out of the plant is fine and safe," said St. Louis Utilities Director Curtis Skouby. "The plant is designed to remove various things from the water and we are monitoring the break and what it's causing."
The break was reported about 5 a.m. Monday. It wasn't immediately clear how much sewage flowed into the river, but MSD officials said the city's water is safe, but the break is a potential environmental hazard.
Crews also set up dams and is pumping the sewage into trucks to stop the contamination. Officials say it could take a few days to fully repair the break. MSD says they are planning to spend more than four billion dollars during the next few decades replacing its aging system.
