Water Treatment Facility

chlorine-water-treatment-tankThe 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 is responsible for ensuring that safe and reliable water services are always provided. The Plant relies on Supervisory Control and Data Acquisition (SCADA) equipment to monitor and operate the water system. Many security practices are incorporated into the operation and we have an extensive backflow program in place.

The City's Water Treatment Plant received the Area Wide Optimization Program Award given by NCDWR for meeting standards above and beyond those required by state regulations. in 2008, 2012, 2013, 2014, 2016, 2017 and 2018.

We are pleased to present to you the 2021 Annual Drinking Water Quality Report. This report is a snapshot of last year's water quality.  Included are details about your source of water, what it contains, and how it compares to standards set by regulatory agencies. Our constant goal is to provide you with a safe and dependable supply of drinking water. We want you to understand the efforts we make to continually improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your water and to providing you with this information because informed customers are our best allies.

The purpose of the Backflow/Cross Connection Program is to

the public potable water supply from contamination or pollution by containing within the consumer's internal distribution system or private water system contaminants or pollutants which could backflow through the service connection into the public potable water supply system.

Promote the elimination, containment, isolation, or control of existing cross-connections, actual or potential, between the public or consumer's potable water system and non-potable water systems, plumbing fixtures, and industrial-process systems.

Provide for the maintenance of a continuing program of cross-connection control which will systematically and effectively prevent the contamination or pollution of all potable water systems.
