There are a number of reasons why the water may be off in your home or business. One of the most common causes is a water main break. Here are a few reasons why a water main break can occur.
Extreme temperature fluctuations in the winter and spring are a leading cause of water outages. As the ground freezes and thaws several times, it can shift the earth and cause water mains to break.

EPCOR Water has initiated a wide range of activities over many years to reduce the number of water main breaks including performing preventative maintenance, water main replacements and renewals, and cathodic protection for water mains that are most prone to break. The impact of these measures is seen in overall year-over-year decreases for the number of main breaks
We started replacing cast iron mains in the mid-1980s, and our water main breaks have decreased overall by more than 80 percent. Approximately only 540 KM out of 4,300 KM of pipe maintained by EPCOR is cast iron.
Since 1997, cathodic protection has been used to extend the life of cast iron water mains by protecting them from corrosion. Cathodic protection is a proven and effective method to reduce break frequency and extend the useful life of those pipes. EPCOR reviewed the effectiveness of cathodic protection in 2004 and 2007. The review showed that water main breaks are approximately 48 percent lower on protected sections of pipe. Currently, we aim to add cathodic protection to 10 KM of cast iron pipe each year, in addition to replacing cast iron mains to accommodate City of Edmonton projects.
