Scheduled equipment upgrades – Newmarket Sewage Pumping Station
From May 19 to 22, 2026, the chemical treatment system at the Newmarket Sewage Pumping Station at 360 Bayview Parkway in the Town of Newmarket will be turned off for equipment upgrades. There will be no disruption to water or wastewater services.
The tank contains safe, effective chemicals used to reduce sanitary sewer odour. As a result of the tank being turned off, residents and businesses may notice a slight odour between May 19 and 23, coming from the sanitary maintenance hole at Yonge Street and North Lake Road in the City of Richmond Hill.
To help minimize odour, York Region will increase the hydrogen peroxide dosage at the Aurora Sewage Pumping Station during the maintenance work. This is a safe and effective way to reduce odour in sewage and wastewater. This treatment will not impact services or residents.
When
- Tuesday, May 19, 2026, at 8 a.m. with return to service expected by end-of-day Friday, May 22, 2026
What can you expect?
- No impact to residents’ water or wastewater services
- Possible slight increase in odour from the sanitary maintenance hole at Yonge Street and North Lake Road in the City of Richmond Hill
In the event equipment upgrades are delayed due to weather conditions, an updated notice will be posted on york.ca and shared on York Region social media channels.
