Boil water advisory issued for downtown Penticton and West Bench

A boil water advisory is in effect for some residents in the Regional District of Okanagan - Similkameen, after a large water main broke.

The advisory applies to specific parts of downtown Penticton and those in the West Bench water system.

Interior Health is advising people with compromised immune systems, the elderly and young children to boil their water until further notice.

The City of Penticton is testing water quality samples and it will lift the advisory once the samples are cleared by the Health Authority.
