Boil Water Advisory issued for Guildford and Yapeen
Coliban Water has issued a Boil Water Advisory for its customers in Guildford and Yapeen following a burst to a water main that interrupted supply.
A Boil Water Advisory is a measure taken when we suspect a potential water quality issue with our customers’ drinking water supply.
A Boil Water Advisory notifies customers to boil their drinking water, and water used for food preparation, until we confirm the water is safe for these purposes.
We are working closely with the Department of Health on this issue and continue to keep customers informed.
Repairs to the burst water main are underway and will be followed by mains flushing and water quality testing. The Boil Water Advisory will remain in place until we can confirm the water is safe to drink.
Information about how to boil water is available on our website www.coliban.com.au/interruptions. Customers can also call our 24-hour faults and emergencies number 1300 363 200, or follow us on Facebook.
