Starting February 26, 2026, Johnston County Public Utilities will implement a chlorine-only disinfection method for the Johnston West water distribution system as part of routine maintenance mandated by state and federal regulations. This treatment will last approximately six weeks, with a return to the normal chlorine and ammonia mixture expected around April 2, 2026.

The change is necessary to prevent bacteria from developing resistance to chloramines. Customers using kidney dialysis machines should note the increased chlorine levels during this period, and tropical fish owners may experience potential harm. System flushing will also be performed to expedite chloramine removal, with minor temporary discoloration expected but no impact on water quality.
