Water pipes can burst for a number of reasons.
- the ground expanding or contracting around water pipes as a result of dry, hot summers or freezing cold weather
- the age or condition of water pipes
- some pipe materials being eaten away due to the soil conditions
- heavy traffic in cities and towns compressing the soil around the pipe.
It's essential to replace mains to prevent increasing bursts.
To measure our future ability to provide water services, we keep a track of our performance on mains bursts.
