Scheduled Chemical Tank Cleaning – Newmarket Sewage Pumping Station

On September 17, 2024, the chemical tank at the Newmarket Sewage Pumping Station at 360 Bayview Parkway in the Town of Newmarket will be turned off for routine cleaning. 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 September 17 and 19, 2024, 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 cleaning. This is a safe and effective way to reduce odour in sewage and wastewater. This treatment will not impact services or residents. 

When 

• Tuesday, September 17, 2024, at 8 a.m. with return to service expected by end-of-day Wednesday, September 18, 2024 

What can you expect? 

• No impact to residents’ water or wastewater services 
• Possible increase in odour from the sanitary maintenance hole at Yonge Street and North Lake Road in the City of Richmond Hill  

In the event tank cleaning is delayed due to weather conditions, an updated notice will be posted on york.ca and shared on York Region social media channels.
