Drinking Water Quality Management Standard (DWQMS)

The Drinking Water Quality Management Standard (DWQMS) defines a framework for operating authorities and owners of drinking water systems to develop a Quality Management System (QMS) that is relevant to their organization. While the DWQMS contains elements of both the ISO 9001 standard and the HACCP standard, the DWQMS was specifically designed for drinking water systems. The adoption of drinking water focused quality management systems is not new; however the requirement to implement the DWQMS is now mandated through the Safe Drinking Water Act (SDWA), of Ontario, Canada.
