The Board of Water Supply tonight advised North Shore residents from Pupukea to Kuilima to conserve water through tomorrow during repair work on a broken 16-inch main.

Residents may experience low water pressure as a result of the 3:30 p.m. main break on the shoulder of Kamehameha Highway, about 200 feet after the bridge heading toward Pupukea, said BWS spokeswoman Moani Wright-Van Alst.

There are no road closures.
