About Us

The groundwater industry in Ontario had its beginnings in the early 1900s. The creation of the Ontario Water Resources Commission (OWRC) was in 1955. The OWRC had the lead in developing regulations, policies and guidelines, and securing abundant and safe groundwater supplies throughout Ontario. The Ontario Ground Water Association was created in 1952 as a not-for-profit organization to facilitate the various sectors of the groundwater industry coming together for the delivery of safe and clean water supplies throughout the Province.


Who we are


The Ontario Ground Water Association has members in 5 divisions of ground water professionals-- Well Drillers, Environmental/Geotechnical Drillers, Pump Installers, Manufacturers and Suppliers, and Scientists and Engineers.
