Measure the effectiveness of Hamilton Water’s treatment systems for the provision of clean, safe drinking water. Standards for drinking water quality are set and enforced by the Safe Water Drinking Act. The City of Hamilton’s drinking water regularly meets all Ontario Drinking Water Standards. Water samples are collected from approximately 113 locations.
Story behind the numbers
The current target for adverse water quality incidents (AWQI) is 0. All AWQI are reportable to the Ministry of the Environment and Climate Change, however once the AWQI is triggered, further sampling dictates whether it is confirmed or unconfirmed. If the AWQI is confirmed, investigative and preventative actions are required to ensure the safety of the drinking water. If the AWQI is unconfirmed no further action is required. The AWQI indicator is influenced by seasonality, external service levels and other factors such as inclement weather and construction activity.
Hamilton Water has a number of initiatives to ensure requirements are met. These include:
- Optimization of the water distribution sampling and testing program to meet and exceed the Ontario Drinking Water Standards
- Development of an Asset Management Plan to rehabilitate and replace aging infrastructure.

DATA NOTE: The Citizen Dashboard is in the process of being converted into an Open Data format, linking the Citizen Dashboard with Open Hamilton. During this conversion, the data on the Citizen Dashboard will not be updated quarterly, resulting in some data being out of date. The conversion is underway and is expected to be fully completed by June 2019.
