Water Treatment Plant

The City of Mount Holly Water Treatment Facility was built in 1983 and is designed to treat up to 6 million gallons per day drawing its water from Mountain Island Lake. Water is treated through coagulation, sedimentation and filtration and then disinfected using chlorine. The City owns and maintains four elevated storage tanks and one ground storage tank to send out roughly 2.4 million gallons per day of treated water throughout Mount Holly. The treatment facility is staffed 24/7 by certified operators and runs a professional lab for testing and analyzing water. The water treatment plant received the 2012 North Carolina Area Wide Optimization Program Award for meeting standards above and beyond those required by state regulations.
