According to WFSB on June 1:

Students at Enfield High School were dismissed early on Monday because there was no water in the bathrooms or the sprinkler system.

Around 11:30 a.m. school administration said construction workers “inadvertently broke” a water main at the school, which caused the school to lose water.

The students were dismissed at 12:45 p.m. The early dismissal will not affect graduation, according to the administration.
