(Erving, MA) Erving residents may experience some water discoloration next week while fire hydrant flushing is underway. Hydrant flushing supports healthy water quality and prevents random occurrences of rust colored water when demand increases, however it can stir up mineral deposits sometimes resulting in rusty or brown colored water. The effect is temporary. The process is expected to begin Tuesday, October 10th through Friday, October 13th between 7:00 a.m. to 2:00 p.m.
