Zone 2 Water Replacement Package 1

The purpose of Zone 2 Water Replacement Package project is to expand Charlotte Water’s ongoing water replacement program by expediting the replacement of older water mains that are of pipe materials known to have a high likelihood of failure. Through research of main break data, a group of neighborhoods have been identified with a high concentration of these water mains made from these pipe materials. This project will focus on the replacement of the galvanized steel pipe (GSP) and asbestos cement pipe (ACP) within the project area but will consider other mains within the scope areas as well if deemed necessary. For this project, Charlotte Water staff believes the Progressive Design-Build delivery method will be best.
