From City of Gloucester website:
Wednesday evening around 11 PM on February 10, 2020, water treatment plant operations will be transferred from West Gloucester to Babson as a part of routine operations. This will result in a change in the direction of flow in some water mains and may cause temporary discoloration of the water as iron particles in the pipe are stirred up. If you should experience “rusty” water, running a cold water tap for a few minutes should clear your line. We also recommend that you avoid the use of chlorine bleach during this time period to prevent staining of laundry.
If you experience persistent water quality problems, please contact the Office of Water Compliance at 978-281-9792 or DPW at 978-281-9785, so that selective flushing can be targeted to problem areas. Thank you for your cooperation.
