The Township of North Dundas has officially opened Wellfield No. 8 on Lafleur Road, bringing a new groundwater source online that will provide a reliable water supply of 20 litres per second for the Ontario municipality’s drinking water system.
Local officials said on May 11 that the project is intended to help meet existing water servicing demands while supporting future residential and commercial growth in the villages of Winchester and Chesterville.
North Dundas’s drinking water system is supplied by eight groundwater production wells located throughout the municipality, which has about 12,800 residents. The new wellfield project was completed in partnership with Louis W. Bray Construction, the Ontario Clean Water Agency and J.L. Richards & Associates.
The township noted that while its eight drinking water wells have a combined rated capacity of 102.75 L/s, drought conditions in 2025 reduced the total combined capacity to 56.8 L/s, highlighting the need for additional and more resilient water infrastructure.

“Bringing this new water source online is a major step in meeting our current servicing demand while preparing for our future water demand,” North Dundas officials said in a statement. “This project is one of the many infrastructure upgrades that we have completed to future-proof the Township of North Dundas, opening the door for new commercial and residential developments.”
The municipality’s drinking water system includes sodium hypochlorite disinfection systems at five pump houses, two storage reservoirs, two elevated tanks and approximately 51 kilometres of distribution piping.
The Wellfield No. 8 project included construction of a new disinfection building with process piping, electrical equipment, instrumentation, control panels and chemical storage and dosing systems. Work also included installation of well pumps and pitless adapters in Wells 8A and 8B, new hydrants and valves on the transmission main, buried watermain piping, and a standby diesel generator.
Additional project components included overland discharge piping for process water, buried conduits for power and controls, concrete housekeeping pads and apron slabs, chain-link fencing and gates, a new access road and site grading works.
The project received funding through the Investing in Canada Infrastructure Program, a joint federal and provincial initiative. The federal government contributed $1.9 million, while the provincial government provided $1.6 million. The remaining project costs will be funded through water rates and future capital connection charges in Winchester and Chesterville.
