Some water customers in the Village of New Concord are under a boil advisory. Officials say two water main breaks occurred Tuesday night and knocked out service to customers on North Friendship Drive – north of John Glenn High School Road only, Cedar Circle, Ridgeview Drive and Jay Layman Drive. East Muskingum Schools are not affected by this outage. Customers are being advised to boil all drinking and cooking water until further notice. Village officials say service should be restored by Wednesday afternoon, but customers may experience low pressure and discolored water and should not do laundry until the water clears. The boil advisory may be canceled by 4:00 p.m. Friday when mandatory water testing will be completed.
