Ultraviolet (UV) treatment at the North End Wastewater Treatment Plant back on

Released: March 18, 2026 at 1:46 p.m.

Winnipeg, MB – Residents who live near or use the Red River for recreation are now able to return to their regular waterway activities.

Ultraviolet treatment at the North End Wastewater Treatment Plant (NEWPCC) has resumed.

UV treatment uses UV lights to neutralize bacteria and viruses in treated wastewater.  

We temporarily shut it off last October to accommodate work on plant upgrades. This resulted in higher levels of viruses and bacteria in the Red River. At the time, we advised people to take precautions around river water to avoid risk of illness.  

“I’m pleased we were able reinstate the UV system on time. With UV treatment on, we can neutralize bacteria and viruses in our treated wastewater again,” said Councillor Eadie, Chair of the Standing Policy Committee on Water, Waste, and Environment. “It also means we can lift the safety precautions for anyone using the Red River, immediately downstream of NEWPCC.”

As a best practice, we still recommend residents wash their hands with soap if they come into contact with river water. We also encourage anyone consuming fish from the river to follow safe food handling practices.

With the completion of this phase of work, the UV treatment system now uses approximately 75 percent less energy.

Upgrades to our UV treatment facility continue and are expected to be completed in Fall 2026.
