GLOUCESTER – For system maintenance the Gloucester DPW on September 17, 2025, switched the Water Distribution System disinfectant from monochloramine to chlorine, and will switch back to monochloramine on Thursday October 16, 2025. Flushing in the distribution system will begin Thursday October 16, 2025, by DPW crews for a week to restore monochloramine throughout the distribution system.
If discolored water is experienced, running of cold water is recommended as flushing can disturb normal flow patterns. If water quality problems persist please call the DPW at 978-325-5600, so spot flushing can be performed as necessary. Monochloramine is the main Chloramine used for disinfection in the distribution system. It is formed when dilute concentrations of chlorine and ammonia are combined at the water treatment plants.
