​Leaks in the home

Leaks inside your home can be costly and waste thousands of litres of water each year. A bursting pipe in your home calls for immediate action but what about those slow leaks that go undetected for years?

Leaky Toilets                 

How well do you know your toilet?

Toilets account for over 30% of all indoor water use and a leaky toilet can be a major source of wasted water. A leaky toilet accounts for over 60% of wasted water and one leaky toilet could fill a swimming pool in one year. 20 to 40 litres of water are wasted each hour if your toilet has a silent/steady leak.

Chances are you have a leaky toilet if:

  • You rattle the handle after flushing to stop water flowing
  • Sounds are coming from the toilet when not in use
  • Holding the handle down to completely empty the tank
  • Water is trickling down the sides of the bowl long after a flush
  • Water running out of the overflow pipe or dripping from the refill tube

Toilet leak detection-The dye test

You can purchase a dye test kit or simply use food colouring. Add a few drops of food colouring to your toilet tank and wait 20 minutes. If you see the water in the toilet bowl turning colour, you have a leak.

Fixing a toilet leak

Do-it-yourself types can buy material and get advice at any plumbing supply store or hardware store OR contact a plumber and have a professional fix your toilet leaks.

Municipal Leaks

What are we doing as a municipality to prevent water leaks?

"Unaccounted for" water, also referred to as "non-revenue water" refers to water that has been produced and is "lost" before it reaches the customer. Losses can be real (as a result of leakage) or apparent (through theft, metering inaccuracies, or authorized unmetered consumption).

Municipal water loss varies across Canada. Alberta's municipal sector will maintain the volume of "unaccounted for" water at 10% of total water use.

The chart below shows municipal water loss by province based on the percentage of leaks for unaccounted water use.


Lethbridge Leaks

What is the City of Lethbridge doing to prevent this costly problem?

Broken watermains, leaky pipes, theft of water and metering inaccuracies can cost the Lethbridge community millions of tax dollars and waste millions of litres of water.

There are several ways the City of Lethbridge is preventing unaccountable water loss. Rather than reacting to a broken pipe we are being proactive by determining how healthy our aging pipes and systems are. We identify leaks and aging infrastructure and fix or replace pipes before it turns into a significant problem.
