Quality Management System


The ENWIN Utilities Ltd. – Water Operations holds a valid drinking water works permit through the province’s municipal drinking water licencing program and is an accredited operating authority. This is demonstrated through our operational and effective drinking water quality management system.

Information about the system is described at length in our operational plan, in accordance with the Safe Drinking Water Act, 2002.

The Safe Drinking Water Act 2002 (SDWA) requires owners and operating authorities to implement a quality management standard specifically designed for drinking water systems be developed and implemented in Ontario. This led to the creation of the Drinking Water Quality Management Standard (DWQMS or the Standard).

The Licensing Program is an approvals framework for municipal residential drinking water systems. In order to be issued a licence, the Ministry of the Environment, Conservation and Parks requires the owner of a municipal residential drinking water system to have the following:

  • A Drinking Water Works Permit (DWWP)
  • A Permit To Take Water (PTTW)
  • An accepted QMS Operational Plan
  • An accredited Operating Authority
  • A Financial Plan
  • Accreditation: Ontario's Drinking Water Quality Management Standard, Version 2

The SDWA requires owners of municipal residential drinking water systems to have an accredited Operating Authority. In order to become accredited, an Operating Authority must establish and maintain a Quality Management System (QMS).
