Missouri American to replace aging water lines south county

Missouri American Water crews next week will begin replacing water lines to enhance service reliability in Sunset Hills and Bella Villa.

The larger diameter pipe will also help to improve fire flows in these areas, according to a news release.

In Bella Villa, roughly 2,200 feet of 50- to 90-year old, small-diameter water mains will be replaced with 6- and 8-inch diameter pipe. The work is slated for completion in late May to early June. New water mains will be installed:

• Along Pardella Avenue between Bayless Avenue and Fannie Avenue.

• Along Risch Avenue between South Grand Avenue and Pardella.

• Along Viking Avenue between Pardella and Baumann Avenue.

• Along Baumann from Viking to the end of the cul-de-sac.

In Sunset Hills, an 80-year old, 6-inch diameter water line will be replaced with 2,700 feet of 8-inch diameter pipe along Denny Road between Sappington Road and Lindbergh Boulevard.

Drivers may notice some closures of the westbound lane of Denny Road during the construction process, slated for completion in mid-July.

Company engineers select replacement projects based upon their community benefits, including reducing water main breaks and improving the overall integrity of the water system in the area, the release stated. Missouri American Water maintains about 4,200 miles of water mains in St. Louis County.

Missouri American Water invested roughly $30 million in area water main improvements during 2011.

Missouri American Water has notified residents about maintaining water service to their homes and businesses during the construction process.
