The Springfield Water and Sewer Commission is NOT part of Dig Safe. Before any excavation occurs, the Commission must be contacted separately to mark out the location of water and sewer utilities at any site where excavation will take place. The excavator is responsible to protect and not damage Commission structures. Underground Utility Mark Out requests must be made a minimum of 72 hours before any excavation begins at the Commission’s Field Services Office at 71 Colton Street, Springfield, MA 01109. Office hours are 7:00 AM to 3:30 PM and the Commission may be contacted at 413-310-3501. Please provide your Dig Safe number as part of the request.
