Johnston County West Water System - Chlorine-Only Disinfection Begins on March 1st


For Immediate Release:  February 17, 2023

 

Smithfield, NC – Beginning on March 1, 2023, the Johnston County Water Treatment Plant will temporarily stop feeding ammonia with chlorine for disinfection and start feeding chlorine only for all Johnston County water customers on the Johnston West water distribution system. The Johnston West distribution system supplies water for many County residents and businesses, which includes Clayton, Wilsons Mills, and some customers serviced by various private utilities. If you have any concerns or need additional information, please contact Johnston County Public Utilities at 919-989-5075.

For Johnston County retail customers, the distribution system is designated on each monthly billing statement. The Johnston West distribution system is shown as the yellow area on the attached map. State and federal regulations require that all public water systems feed chlorine only for at least three weeks each year to insure that no bacteria are present, which may have adapted to the ammonia in the water.

Johnston West customers that use kidney dialysis machines should be aware that the water will contain more chlorine for about five weeks and will return to a chlorine and ammonia mixture on or about April 3, 2023. The chlorine only water can be toxic to tropical fish. Most customers will not notice a difference in their water, but some may detect a chlorine odor and might observe a slight color change.

The County will also conduct flushing of the Johnston West water distribution system during this period to speed the removal of chloramines from the system. The flushing process may result in some minor and temporary discoloration of water that does not affect water quality. If any related issues cannot be cleared by flushing the lines inside your home, please call 919-989.5075.
