As part of modernizing our practices, the North Chelmsford Water District is moving towards digital data collection and management, including mapping the water distribution system (hydrants, water mains, etc.). The data collection will be done by our own staff, equipped with yellow Hi-Vis vests, walking and driving around the District. Please be advised that they may mark roads and sidewalks with white or blue spray paint. If you have any questions, please contact us at (978) 251-3931.
