SUBJECT: Notice of Wastewater Treatment Plant Tertiary Bypass 

Please be advised that due to high flows caused by rain and spring freshet, the Minden Wastewater Treatment Plant began a tertiary sand filter bypass on Sunday, March 16, 2025. All wastewater treated at the plant is still receiving primary and secondary treatment and disinfection prior to discharge. Sand filtering will resume as soon as possible. 

Ontario Clean Water Agency has notified the local health authorities and will be completing sampling as per the Environmental Compliance Approval. 

Residents are reminded that any water taken from a surface water source (such as a lake or river) must always be adequately treated to remove pathogens prior to using as a potable water source. 

Updates regarding this bypass event will be posted on the Township website.
