Ontario Drinking Water Quality Management Standard (DWQMS) Verification

Receive third-party verification as an accredited operating authority and meet the requirements of the DWQMS.

The Ontario Safe Drinking Water Act, 2002 requires an accredited operating authority to oversee all municipal residential drinking water systems.

This operating authority must establish and maintain a quality management system that meets the requirements of the Ontario Drinking Water Quality Management Standard (DWQMS).

NSF International Strategic Registrations (NSF-ISR) serves as one of only two approved accreditation bodies for the DWQMS and provides third-party verification for operating authorities like your company.

In addition to meeting standard requirements, your company will have access to:

  • A robust team of DWQMS experts who make the verification process more effective and efficient
  • Lead auditors with more than 10 years of direct QMS experience, deep industry knowledge and relevant insights
  • Highly qualified experts who can assist with the transfer of existing certifications
