Bozrah — A “significant” water main break on Fitchville Road has cut off water service to 241 Norwich Public Utilities customers in Bozrah and could affect water pressure throughout the NPU water system, officials said Friday.

The break was discovered about 6:45 a.m. Friday. Crews excavated the road in two places to cut out and replace two 12-foot sections of the 30-inch water main, NPU spokesman Chris Riley said. An update from NPU on Friday night said that as of 7:45 p.m., crews "have made substantial progress in repairing the water main."

Riley estimated that water service would be restored in Bozrah early Saturday morning.

Compared to the damaged section at the intersection of Bashon and Fitchville roads, the damage around 171 Fitchville Road has proven more difficult to fix, Riley said, because of heavy ledge in the area.

Bottled water is available at the Bozrah Public Works garage, 227 Fitchville Road, for customers affected by the break, and NPU has contacted commercial customers in the area.

NPU water customers were encouraged to conserve water throughout Friday to help maintain water pressure. Customers living in high elevation neighborhoods could see a slight drop in water pressure. These areas include Rockwell Street, West Thames Street and Laurel Hill.

NPU water customers could experience slightly discolored water during the repairs. By opening the cold water taps and allowing the water to run for five minutes, the issue should be resolved, NPU officials said, adding that this incident has no impact on water quality in Norwich.
