🚨 BOIL WATER ORDER UPDATE – JULY 10, 2026 🚨
The Town of Guilford is sharing the following update from Connecticut Water regarding the mandatory Boil Water Order, which remains in effect for customers served by the Guilford Water System.
Connecticut Water continues to work closely with the Connecticut Department of Public Health after E. coli was detected in one routine water sample collected in Essex. As a precaution, the Boil Water Order remains in effect for customers in Deep River, Essex, Haddam, Chester, Old Saybrook, Westbrook, Clinton, Madison, and Guilford while additional testing is completed.
Connecticut Water understands this situation is disruptive and appreciates everyone's patience. The company performs more than 120,000 routine water quality tests each year, and this boil water order is required by the Connecticut Department of Public Health while follow-up testing is underway.
