ST. LOUIS COUNTY, Mo. – St. Louis County will have new water pipes as Missouri American Water announced it is replacing approximately 95,000 feet of water main beginning this month.

The $52 million investment will increase service reliability for Missouri American Water customers and strengthen water flows in fire hydrants, according to a press release from Missouri American Water.

The replacement includes upgrading four-inch, six-inch, and eight-inch mains that were initially installed between the 1920s and 1960s. The previous pipes will be replaced with new 12-inch and 16-inch ductile iron mains.

Some of the major areas for replacements include W. Florissant Avenue, Page Avenue, Dale Avenue, N. Lindbergh Boulevard, MacKenzie Road, and S. Laclede Station Road.  

“Maintaining water mains are equally as important as maintaining our roads and bridges,” St. Louis County Councilwoman Rita Heard Days said in a statement. “Residents in the community will benefit by having safe, reliable water when they turn on the tap.” 

Construction for most projects will start in January and run through May, Monday-Friday 7 a.m. to 5 p.m. Service line transfers and street restorations are set to be completed in July, according to the press release.
