Drinking Water Quality Management in Peel

As a stakeholder (developer, land owner, consultant or contractor) working on infrastructure that is part of, or will become part of, the Region of Peel’s municipal drinking water system, this document serves to inform you of applicable provincial legislative and regulatory requirements in accordance with the municipal drinking water licensing program approvals framework.

Statutory obligations

The Region of Peel (the Region) operates its drinking water systems in compliance with provincial legislation, including the Safe Drinking Water Act, 2002 (the Act) and its supporting regulations. The Act is the principal legislation regulating the treatment and distribution of drinking water in Ontario; imposing a statutory Standard of Care for system owners and operating bodies, defining water quality standards, operator training and certification, accreditation and licensing of water system operating authorities and water testing laboratories, water sampling, testing and monitoring requirements, adverse water quality reporting and corrective actions as well as water system inspections and enforcement by the Ministry of the Environment, Conservation and Parks (the Ministry).

Municipal Drinking Water Licensing Program

The Municipal Drinking Water Licensing Program, implemented by the Ministry under the Act, requires municipal drinking water systems owners to be licensed to operate and operating authorities to establish and maintain a Quality Management System (QMS) accredited to the Drinking Water Quality Management Standard (DWQMS). The Region is a full scope DWQMS accredited operating authority and has successfully maintained this status since first awarded in 2011.

The Municipal Drinking Water Licence (MDWL) is comprised of five components:

Responsibilities and duties

Drinking water system operation, maintenance and alteration are governed by the MDWL and DWWP conditions, applicable acts, regulations, codes of practice, and industry standards. These requirements place responsibilities on the Region and they are relevant to all water infrastructure projects and vary depending on the scope of work. The legal owner of any part of the drinking water system, or any person authorized to carry out work on the drinking water system, is expected to comply with the QMS and with the following:

The appropriate approvals must be in place prior to commencement of work to construct or to alter the drinking water system. The Region has the authority to approve most of the system alteration projects through the DWWP by completing the Ministry mandated forms (Form 1, Form 2 and Form 3).

Where works cannot be approved by the Region, a formal application for approval to the Ministry must be submitted and approval received prior to commencement of work to construct or to alter the drinking water system. Amendments to the Region’s drinking water approvals must be made in direct consultation with the Region’s staff.

Quality Management System

The Region has implemented a Quality Management System (QMS) for its drinking water systems. This ensures the policies and procedures are in place to effectively manage the drinking water operations, continuously test and check and make improvements to all aspects of water treatment and distribution, from source to tap.

The Region’s commitment to drinking water quality is summarized in the QMS policy below:

The Region delivers on its commitments by ensuring quality and integrity of supplies and services acquired. All purchasing is in accordance with the Region’s Purchasing By-laws, supplemented with internal procedures that outline resources that are necessary for the delivery of safe drinking water. The Region’s expectations on quality of products and service delivery are communicated through tender documentation, purchasing agreements and contracts. Performance of vendors retained by the Region is monitored and evaluated through a Vendor Satisfaction Survey to ensure that goods and services comply with established requirements.
