Drinking Water Wastewater Stormwater
Like many urban areas, the majority of City of Concord’s drinking water comes from one of three lakes or reservoirs: Lake Concord, Lake Don T. Howell or Coddle Creek, and Lake Fisher. We also have the ability to get water from the Yadkin River via the Albemarle waterline. Two water treatment plants, Hillgrove and Coddle Creek work to remove sediment, organic matter and pathogens. Clean water then travels to Concord homes and businesses.

The first step in water treatment is coagulation. Special compounds are added to the water to cause suspended dirt particles to stick together. Since the stuck-together particles weigh more, they sink to the bottom and are discarded during sedimentation in which finer and finer particles settle out of the water. The water then moves through a series of filters for further purification. Finally, pathogens are removed in the disinfection step and the treated water is sent to customers.
Next, comes sedimentation which those particles settle to the bottom.
After sedimentation comes filtration which further purifies the water by removing smaller particles.
After bacteria and other pathogens are removed through disinfection, it’s on to residential and commercial customers.
