Update: Boil Water Order


Saint John Water has flushed the system and begun testing the water and providing the results to the Department of Health for review. The boil water order will remain in effect until acceptable chlorine residuals have been measured and maintained and two consecutive acceptable sets of bacteriological results no less than 24 hours apart are reported to Public Health. Residents will be notified once the water is safe to drink again.

Saint John Water continues to investigate the root cause of the chlorinator failure, and is working with the equipment manufacturer and the system designer so that it can be addressed and additional redundancies built into the treatment system to prevent such a re-occurrence. The drinking water treatment equipment at Saint John Water undergoes regular inspection and preventative maintenance. Saint John Water’s operations across the City are monitored by a SCADA (Supervisory Control And Data Acquisition) system, which is a system for remote monitoring.  The SCADA system ensures that if a system malfunction or failure occurs in the operation, Saint John Water operators are promptly alerted.

While the boil water order is in effect, water system users are reminded to bring their tap water to a rolling boil for at least a minute and let it cool before consuming it. Water that has been treated in this manner is safe to drink.

The City will notify residents once the Department of Public Health has lifted the boil water order. Notifications will be provided to the media, sent to “City News” subscribers (which residents can sign up for on the website), posted on www.saintjohn.ca, and shared through the City’s official Twitter and Facebook accounts.
