Annual Water Changeover Begins March 1

Beginning Wednesday, March 1, 2017, PWC will temporarily stop adding ammonia to its water treatment disinfection process. The N.C. Department of Environmental Quality requires all water systems that add ammonia to their drinking water to discontinue its use for a one-month period annually to ensure that any biological growth that may have occurred within the distribution system is controlled. PWC will resume adding ammonia to the water treatment disinfection process on Saturday, April 1, 2017.

During March, fire hydrants on the PWC water distribution system will be opened periodically to flush the water distribution system. Some customers may notice chlorine odor as a result of this change in our treatment process or experience periods of discolored water as a result of the system flushing.

Water customers should be aware that during this time, traces of ammonia could remain in the water. PWC recommends that water customers who pre-treat should continue to follow procedures to remove chloramines.
