A water filtration plant in Hawkesbury, Ont., flooded Sunday night, leading to boil water advisories for Hawkesbury, L'Orignal and Vankleek Hill in eastern Ontario.

The flood caused significant pressure loss and the plant is unable to filter water for the approximately 13,500 businesses and residences it serves. But water that was already in the system's tanks is still flowing out of taps.

The Township of Champlain is advising residents to moderate water consumption.

On Monday morning the communities of L'Orignal and Vankleek Hill were reconnected to the Hawkesbury water system, and boil water advisories have been issued temporarily as a precaution.
