Crews with Charlotte Water, formerly Charlotte-Mecklenburg Utilities, began replacing drinking water pipes this week in Matthews.
The project will eventually encompass West Matthews, North Ames, Main, South Ames, Freemont, McDowell and South Trade streets.
The project is needed to connect existing customers to new or other drinking pipes and abandon two-inch galvanized pipes in those areas, Matthews spokeswoman Jen Thompson said.
Work started first on West Matthews Street and will last about two weeks.
Never miss a local story.
Crews will then move to North and South Freemont streets through May.
Work on McDowell Street will begin about mid-June, when classes at Matthews Elementary end for the summer.
Construction on other streets will be dictated by progress on those first projects.
Most of the construction will take place between dawn and dusk.
Work on state-maintained roads, including like South Trade, McDowell and John streets, will be restricted to between 9 a.m. and 4 p.m.
Water outages may occur during the project, Thompson said. Residents and businesses will be notified 72 hours in advance of a scheduled outage. Any unplanned outages will be treated by the contractor immediately, she said.
The project is scheduled to be completed in August before the start of the 2015-16 school year, Thompson said.
