This week, Global News has published a story on lead water pipe infrastructure across Canada, and in the City of Calgary specifically. In response to what has been published, The Water Utility is re-sharing the information below on this issue, and to ensure Calgarians that are water is safe, and there is nothing to worry about.

The City of Calgary provides safe and reliable drinking water to citizens. Water Services takes their responsibility to protect public health every day very seriously.

The City tests Calgary’s water over 100,000 times a year, and the water produced and delivered to Calgarians meets or is better than guidelines set by Health Canada, including lead.

Lead service connections were only used for a short time period, primarily between 1939 and 1947, during World War II when copper was not readily available. Following the war, copper once again became the main material for service lines. The City’s data shows that it is rare to find a home built after 1950 that has lead service lines on public or private property.

In Calgary, we currently have approximately 550 known public service lead connections.  When compared to our total number of 339,000 customers this represents only 0.2% of homes receiving water service. In other words, 99.8% of Calgary homes do not have public lead service connections.

The City works with any homeowners who have concerns to investigate their situation.  When a property is identified as having lead service pipes, we offer a number of services to ensure high quality drinking water including testing, filter rebates and replacement. We also reach out proactively each year to residents whose properties has been identified as having a public lead service connection. 

Since regulations were updated in March (federally) and June (provincially), The City continues to review Tap Water Sampling Program and we are exploring options to assist and reach out to customers in more ways for 2020.
