A 30-inch water main broke in Cary on Monday morning, The News & Observer previously reported. It triggered a system pressure advisory in the Town of Cary that caused Wake to dismiss 30 schools in Cary and Morrisville.
“This decision was made out of an abundance of caution and due to the large number of schools affected,” the school district said on its website. “Details about dismissal times for individual schools will be forthcoming to affected families shortly via email and phone messages.”
The closures are not expected to be a multi-day issue.
The district said it expects to resume classes at those 30 schools on Tuesday. Wake said it will notify families as soon as possible if the water main situation impacts schools again on Tuesday.
The water main break led to an advisory for Cary and Morrisville water customers to boil their water before consuming.
