Water Treatment

Notice: Watermain Flushing and Hydrant Testing 2024

The Ontario Clean Water Agency (OCWA) will be flushing watermains and testing fire hydrants between Monday May 13th and Friday May 17th. Flushing will take place between the hours of 8am and 3pm.

This preventive maintenance practice ensures the proper operation of fire hydrants and flushes accumulated sediment from the distribution system. While flushing is underway, short periods of low pressure and discoloured water can be expected. Any discolouration is temporary and is not a health hazard. To restore clarity, remove the aerator and turn on a cold water tap until the water runs clear. Residents are asked to minimize water consumption and avoid doing laundry when flushing activity is observed in your vicinity.

If you have any questions regarding the flushing program, please contact the Water & Sewer Department at 613-396-3436.

Confirmed Harmful Algae Bloom (HAB) for Mohawk Bay, Deseronto – August 25, 2020.

Confirmed Harmful Algae Bloom (HAB) for Mohawk Bay, Deseronto – August 25, 2020.

The Ministry of the Environment, Conservation and Parks (MECPs) Drinking Water and Environmental Compliance Division has confirmed the presence of a blue-green algal bloom at the Mohawk Bay – and at the Deseronto public boat launch, 183 Main St.

Blue-Green Algae can foul the water and cause smelly water. Several species of cyanobacteria in the algae can create toxins, which pose health concerns. A water sample was taken by the Ministry of the Environment on August 14th, 2020 and analysis confirmed the cyanobacteria in our blue-green algae (specifically: Gloeotrichia, Microcystis). This is a health concern.

The processes of the Deseronto Water and Wastewater Treatment Plant remove the health risk posed by blue-green algae and extra testing is performed starting in June through October to ensure safe drinking water. People are advised to avoid water contact in the Bay and at the Deseronto Boat Launch area.

For general information on blue-green algae, please refer to the MECPs website at http://www.ontario.ca/environment-and-energy/blue-green-algae

Trust the Tap - Walkerton Commemoration

This month marks 20 years since the water supply in Walkerton, Ontario was contaminated with E. coli and Campylobacter jejuni bacteria, resulting in the death of 7 people and severe illness affecting over 2,000 people.

Since May 2000, the Provincial government, Municipalities, Conservation Authorities and Source Protection Committees throughout much of Ontario have done tremendous work to improve the quality of municipal drinking water by following the recommendations of the Walkerton Inquiry which was led by Justice Dennis O’Connor.

As we remember the Walkerton tragedy, we acknowledge the hard work and integral part our municipality has played in the multi-barrier approach to safer drinking water.

The multi-barrier approach ensures that municipal drinking water is protected and improved from the source to the tap.  After 20 years, it is time to recognize the important work that has been done to make municipal drinking water safe.

Hydrant Flushing starts May 4th. at 8:00 am

Reminder that Hydrant Flushing will begin next week.

Remember that the only safe thing to flush is toilet paper. This is especially important during the COVID-19 pandemic, as the Town is attempting to preserve staff resources by limiting preventable service calls. Disinfectant wipes, paper towels and facial tissues do not break down and can cause clogs and costly damage to waste water systems and home plumbing systems.
