Water Main Flushing Program


Regular water main flushing is an important component of a comprehensive water quality management program. The Town of Newmarket's Water Main Flushing Program flushes over 300 kilometers of water mains. The Town's Operations Department and approved contractors, in coordination with the Region of York, flush potable water at a high velocity through the water mains to ensure that all piping is refreshed and minor sediment within the pipe is removed. Fire hydrants are generally used as flush-out points. This is just one of the methods that the Town uses to help keep Newmarket's drinking water safe and clean.

While this program is underway, short periods of low pressure and discoloured water may be expected. Any discolouration is temporary and not a health hazard. Residents are asked to minimize their water consumption and avoid doing laundry if a change in water appearance is noticed. To clear water lines, residents are advised to turn on their cold water tap in a bathtub or laundry tub until the water runs clear.

Should water discoloration persist, residents should contact the Town of Newmarket at 905-895-5193 or at info@newmar​ket.ca.

The Town appreciates the cooperation and understanding of its residents during this program, and we thank you for your cooperation and apologize for any inconvenience this program may cause.
