Water leaks and basic repairs

Reducing household leakage could save many litres per household per day. When it comes to residential and household leaks, toilets and faucets are the most common culprits, although any water using device can eventually leak.

Did you know that a leaky or broken toilet can result in water loss and a high water bill? Customer experience shows that, depending on the size of the leak, from slow dripping through a gasket to running water because of a broken flapper, a bill can increase anywhere from $20 to $1500 or more per month. Save water and avoid high water bills by taking the Leaky Toilet Test and check your toilet for leaks.

At just one drop per second a leaky tap can waste over 31,000 litres of water a year. Fixing most faucet leaks is easy and inexpensive and could save you about $100 a year.

To check for hidden leaks use your water meter:

In Calgary most water meters are installed inside the house where the water pipe enters your home. This is usually in the basement, near your main water shut-off valve.

  1. Turn off all taps and water appliances (humidifiers, ice makers) in your home
  2. Watch the triangle shaped dial on your meter
  3. If it keeps turning, you have a leak in your house
  4. Check your toilet, taps, humidifier, hot water heater, water softener and any other water using device for leaks

What to do when you find a leak?

Follow our simple toilet repair or faucet repair instructions, hire a plumber, visit a hardware store for repair tips, watch a Youtube video or pick up a how-to book with detailed instructions.

If you can hear your toilet running, turn off the water immediately and call a plumber if you can’t fix it yourself.

For questions related to high water consumption and leaks or billing adjustments you can call ENMAX at 403-310-2010 or via email at To be considered for a billing adjustment related to a water leak you must complete the High Water Consumption Investigation Checklist and contact ENMAX. This must be done within 3 months (90 days) from when you receive your first invoice with higher than normal water consumption.

The City of Calgary: Leading the way

Monitoring water loss

The City continually monitors our water distribution system for leaks. Some main breaks (or leaks) could go undetected for months if it weren't for The City's commitment to testing and evaluating the newest leak detection methods. District Metered Areas (DMA's) are tested to monitor water loss throughout the system and are instrumental in determining when new breaks or leaks occur.

Water pressure management

The City is also piloting Pressure Management Areas (PMA's) to track water pressure based on peak demand periods. PMA's help reduce water loss and may contribute to fewer main breaks because they actively control system pressure. The City's work in these areas ensures repairs are made in a timely manner, which minimizes damage caused by breaks or leaks in our water distribution system and reduces the costs associated with them. Plus, by proactively managing the water distribution system, The City saves thousands of litres of water every month.​​​​​​
