Customers may experience some water discoloration. Groton Utilities suggests that customers check their water prior to doing laundry to avoid discoloration of clothes. If water discoloration is experienced, flush your system by running the water until it is clear. Once the water is clear, it will be safe for drinking and cooking. If water discoloration persists, please contact Groton Utilities’ Customer Care Center at (860) 446-4000.
