Public Utilities

The Public Utilities Department is dedicated to providing safe and reliable drinking water, and wastewater collections for nearly 17,000 homes and businesses through the operation and maintenance of two water treatment plants, one wastewater treatment plant and over 600 miles of water and sewer lines.

The Business Office manages water/sewer billing and collects other payments due to the Town of Mooresville.

The Town adopted its 2021 Water and Wastewater Comprehensive Master Plan at its regular Board of Commissioners meeting on November 15, 2021.  This plan will guide investments in our utility program through 2045 to ensure that we can meet current and future customer needs and continue to provide the highest quality service possible to our water and sewer customers.  A copy of the Executive Summary is available online

Staff in the Water/Sewer Maintenance division installs, cleans, maintains, and repairs water and sewer lines, pump stations, and water meters. In addition, the Backflow program is operated out of this division. The Town's Backflow Coordinator ensures that customers whose specific types of water use could expose the water system to pollutants installs and maintain proper backflow devices, in accordance with North Carolina law.

The Town of Mooresville owns and operates two water treatment plants located on Charlotte Highway (US 21) with a combined treatment capacity of 18 million gallons per day. Water from Lake Norman is treated and quality tested before being sent into the distribution system. The Town currently produces approximately 5.5 million gallons per day, but that number rises to 7.5 million gallons per day in the summer.

The Rocky River Wastewater Treatment Plant is located on Johnson Dairy Road and is designed to treat 7.5 million gallons of residential, commercial, and industrial wastewater per day. Solids removed from the wastewater are sold as a Class A soil supplement for agricultural purposes. In addition to treating wastewater, the wastewater staff works closely with area industries, restaurants, and residents to provide education on what should and should not be sent down the drain. This is to protect the pipes in your building, and the Town's collection system from clogs. For more on the Town's Fats, Oils, & Grease Program (F.O.G.) visit the Fats, Oils, & Grease page.
