BOIL WATER ADVISORY: Residents of Vienna and Port Burwell

Last Updated: April 19, 2019

April 19, 2019

From the Office of Dr. Joyce Lock, Medical Officer of Health, Southwestern Public Health







To Consumers of Bayham Secondary Water System including Port Burwell and Vienna:


The Medical Officer of Health, Dr. Joyce Lock, is advising that once the water supply has been restored, users bring water to a rolling boil for at least one minute prior to using it for domestic purposes e.g. drinking, making infant formula and juice, brushing teeth, washing raw foods and making ice. 


The reason for the advisory is that the Medical Officer of Health has been advised that a water main break occurred on Nova Scotia Line on April 19, 2019 and could have compromised the water supply. The boiling water advisory is recommended as a precaution in case the loss of pressure possibly led to contamination. All consumers located in Vienna and Port Burwell are being notified of this advisory.


A “Boil Water FAQ” is available from the Southwestern Public Health Unit website at: 


This advisory measure is in place until such time as bacteriological tests prove the water to be safe.

Please direct questions to our Environmental Health Department at 519-631-9900.
