Missouri American Water Announces $3 Million Water Main Upgrade in South St. Louis County

The water utility is working in conjunction with St. Louis County to minimize disruptions to the area. Crews will begin installing new eight-inch PVC water main to replace the aging eight-inch cast iron main that was originally installed in the 1940s.

“We’re excited to improve water service and keep life flowing to our customers in South St. Louis County by replacing old water mains that are reaching the end of their useful life,” said Rebecca Losli, Director of Engineering. “Customers will see an uptick in our crews and contractors working around St. Louis County this spring and summer as more pipe replacement projects get underway.”

Crews will break ground on Mattis Road the week of March 14. Work will take place Monday - Friday from 7 a.m. - 4 p.m. until October in three phases:

• Phase one: Between Langtree Drive and Venarde Drive, crews will replace 2,040 feet of main.
• Phase two: Between Venarde Drive and Ambs Road, crews will replace 2,035 feet of main.
• Phase three: Between Ambs Road and Tonga Drive, crews will replace 2,280 feet of main.

Service line transfers and street restoration are expected to be completed by the end of 2022.
