ST. LOUIS (KTVI) – The public is being asked to avoid more than a mile-long stretch of the River des Peres after a blocked sewer caused tens of thousands of gallons of raw sewage to flow into the waterway.

According to Lance LeComb, a spokesman for Metropolitan St. Louis Sewer District (MSD), crews discovered a blocked sewer main near the intersection of Manchester and Mitchell avenues on Monday, October 19. The blockage was cleared, but an estimated 90,000 gallons of sewage entered the River des Peres.

LeComb said approximately 6,000-feet of River des Peres was affected by the spill, from the discharge point to just beyond where Arsenal Street crosses the river.

There is no immediate threat to public health or safety, LeComb said, but people should avoid that part of the river for the next 48 to 72 hours while cleanup protocols can be initiated. Should anyone come into contact with river water from this area, LeComb said they should immediately wash with soap and water.

The Missouri Department of Natural Resources was notified of the discharge.
