Notice Regarding Public Water Supply - Water Distribution System Partial Transfer from Johnston East to Johnston West - Disinfection Change from Chlorine to Chloramines

On July 17, 2023 and July 24, 2023, Johnston County will convert portions of the water distribution system from Johnston East to Johnston West.  This will change the disinfectant in the water supply from chlorine to chloramines (combination of chlorine and ammonia).  This permanent modification is intended to benefit the service areas by reducing the levels of disinfection byproducts (DBPs) in the system, while still providing protection from waterborne disease.

It is important for anyone dependent on kidney dialysis machines to recognize this change of disinfectants and consult with their health care professional.  Furthermore, chloraminated water may be toxic to some fish.  If you have a fish tank, additional treatment modifications may be required.

Most customers will not notice a difference in their water, but some may detect slight taste and odor changes.  The County will conduct water main flushing in these areas when the supply modifications are made.  The flushing modifications may result in some minor and temporary discoloration of water that does not affect water quality. 

Any customers experiencing water quality issues that cannot be cleared by flushing the lines inside the home or customers with questions, should contact Johnston County Public Utilities at 919-989-5075.

 Winter Weather Alert
(Office Hours and call-out response times are affected by icy road conditions.)

We would like to remind our water customers to be prepared for freezing winter temperatures that could cause frozen water lines. We encourage you to:

  • Wrap any exposed pipes.
  • Check all outside faucets and remove water hoses.
  • Close all vents on the outside of your home.
  • Keep meter box lids tightly closed.
  • Open cabinet doors under kitchen and bathroom sinks to allow heat inside.

If you have water pipes that are subject to freezing, try to keep a steady trickle of water running from the nearest faucet. If you have frozen pipes, but some water is running, the safest thing to do is to wait for the frozen pipes to thaw. Never use an open flame to thaw waterlines. Once the pipes thaw out again, be sure to check for cracks or leaks that may occur from freezing. During inclement weather, our Field Technicians respond to service calls when roads are safe to travel.

Please anticipate delays in service restoration when snow and ice conditions exist in your area. For further assistance, please call 919-989-5075.

County’s Mandatory Year-round Conservation Policy 

The policy allows for alternate day irrigation for irrigation systems and hose-end sprinklers based on the customer’s address.  Odd number street addresses are allowed to water on Tuesdays, Thursdays and Saturdays, while even number street addresses are allowed to water on Wednesdays, Fridays and Sundays.  No irrigation is allowed on Mondays.  Pool filling days should correspond with allowed irrigation days.  Please visit our website at www.jcutil.com for the full policy and water conservation suggestions.  We sincerely appreciate your cooperation.  Please contact Johnston County Public Utilities at 919-989-5075 with any questions.
