How we manage water quality
The Region of Waterloo treats and tests the city’s drinking water to meet the province's standards for safety and quality.
The City of Waterloo maintains the water system that delivers this water to your home or business.
Learn more about regional water treatment and testing on the Region of Waterloo water page.
Watch the Safe Drinking Water video to learn how we provide reliable, clean drinking water.
Check a water issue
Find out what to do if you have a problem with your water:
- discoloured water or low pressure – learn how to clear your tap or check for pressure issues
- boil water advisories – if one is ever needed, the Region of Waterloo and the city will notify affected residents through the service alerts page, local media and other public channels
- request in-home lead testing – homes built before 1989 may qualify for free testing
Subscribe to service alerts for updates about water issues in your neighbourhood.
Drinking water quality management system
The City of Waterloo holds a drinking water works permit through the province's municipal drinking water licensing program and is an accredited operating authority.
We follow a Drinking Water Quality Management System (DWQMS) that guides how we operate, monitor and improve our water distribution network. Learn more in the operational plan (PDF).
Our Quality Management System Policy (PDF) shows our commitment to:
- providing safe drinking water
- meeting all legal and regulatory requirements
- continually improving how the system is managed
- communicating openly about drinking water quality
Under the Safe Drinking Water Act, 2002, the city also maintains a six-year financial plan to support the long-term sustainability of our water system. Read the financial plan (PDF).
