The Columbia County Water Treatment Plants provide water for approximately 95,000 Columbia County residents. There are two drinking water treatment facilities: The Jim Blanchard Water Treatment Plant and The Clarks Hill Water Treatment Plant. Currently, the Jim Blanchard Water Treatment Plant is permitted to withdraw up to 46 million gallons per day from the Savannah River.  The Clarks Hill Water Treatment Plant is permitted to withdraw up to 8 million gallons per day from the Clark Hill Reservoir.  Each plant is responsible for treating surface water to a point where it is safe for human consumption.

The goal of water treatment is to make the water safe to drink by removing biological and chemical contaminants. Numerous processes are used to accomplish this including chemical addition, coagulation, flocculation, sedimentation, filtration, and disinfection. The drinking water produced at our facilities is analyzed over 35,000 times per year for over 115 substances. Some of the quality control tests we perform at our plants are:

  • Pre and Post Chlorine
  • Fluoride
  • Manganese
  • Iron
  • pH
  • Alkalinity
  • Jar Tests

This rigorous testing ensures that the water meets all applicable water quality standards set forth by the Environmental Protection Agency.  Learn more about the water treatment process.

Along with making your water safe to drink, we also monitor various statistics throughout the County by means of a state-of-the-art SCADA (Supervisory Control and Data Acquisition) system.  The SCADA system displays tank levels, system pressures, and pump statuses.  We trend this information to aid in finding possible trouble areas before they affect our customers. 

A report on the quality of the water supplied by the department, the Water Quality Report, has been sent to each of our customers and is available here in .pdf format.

For the story of our water, see the Water Supply & Reliability page.
