Missouri American Water to invest $52 million in new pipes for St. Louis County

ST. LOUIS COUNTY, Mo. – St. Louis County will have new water lines as Missouri American Water said it will replace approximately 95,000 feet of water main starting this month.

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

The replacement includes upgrading the four-inch, six-inch and eight-inch mainlines that were originally installed between the 1920s and 1960s. Previous lines will be replaced with new 12-inch and 16-inch ductile iron lines.

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

“Maintaining water lines is just as important as maintaining our roads and bridges,” St. Louis County Councilman Rita Heard Days said in a statement. “Residents of the community will enjoy safe and reliable water when they turn on the tap.”

Construction on most projects will begin in January and continue through May, Monday through Friday, 7 a.m. to 5 p.m. Service line transfers and street restorations are expected to be completed in July, according to the press release.
