Watermain breaks happen when a pipe has a leak or breaks, affecting the water service to our homes and businesses. They may affect water pressure, or cause pooling of water in our streets and neighbourhoods. They are caused by various factors, including natural causes such as the age of pipes, temperatures, and materials.

On average, the City of Lethbridge repairs between 50 and 100 watermain breaks each year. Each break offers unique challenges, so we follow a specific process so there is minimal disruption to residents and businesses while ensuring access to safe, clean drinking water.

Our residents are our eyes and ears in the community. If you see water pooling on the streets or have a loss of water pressure in your home, please call 311.

We can investigate and help you come up with solutions. Watch the sewer problems video for more information.

What does a water meter do?

Water meters are an important part of your home's water supply and increase your control over your water bill. A properly working meter records the amount of water supplied to your home or business ensuring you only pay for the water you use. Water meters measure and record the amount of water supplied to a home or business. 

Where is my water meter located? 

A water meter is located just above the main water shut-off valve in your home. This is usually in the basement and is located on a pipe that comes out of your basement floor.

Call 311 if you have any questions about your water meter.

If you notice a City crew operating a fire hydrant, flushing water down the street, they are actually cleaning the watermains in the area. Regular flushing is an important component of a comprehensive water management program. The City of Lethbridge is responsible for maintaining and operating 570 km of watermains and more pipe is added each year. Flushing the mains using water under pressure cleans out these pipes, along with the rest of the system. Flushing is generally done between April and October.

When winter temperatures hit extreme lows, the City of Lethbridge reminds residents to take extra measures to protect their home and prevent water pipes from freezing. Find more information on frozen water lines.

Lead service lines were only used for a short time, before 1955 when copper was not readily available. The City of Lethbridge's data shows that it is uncommon to find a property or business built after 1955 that has lead service lines. Water provided by the City of Lethbridge contains very low levels of lead. Tests of our drinking water have consistently shown lead levels of less than 0.2 parts per billion, only 4% of the 5 parts per billion maximum acceptable limit.


Today, according to our records, there are approximately 200 homes in Lethbridge that may have lead service lines. When compared to the total number of over 34,000 connections in the City, this represents only 0.59% of homes receiving water service. In other words, according to our records, we would expect that over 99% of Lethbridge homes do not have lead water service lines. In July of 2020 letters are being mailed to all owners and occupants of properties that are suspected to have a lead service line. The City of Lethbridge's goal is to eliminate all lead service lines within the city by the end of 2022.
