Temperature changes (such as extreme cold and prolonged dry spells) can cause the ground to move – putting strain on our underground water mains and causing them to leak. Illegal standpipes, high commercial water use and other industrial misuse can also lead to unexpected pressure surges in the water mains, which can lead to burst pipes.
Many of our water main pipes are metal and starting to show their age, so we're aiming to replace them with plastic pipes to protect water supplies well into the future.
If we need to repair a leak outside your property
- One of our inspectors will attend to identify the cause and arrange to make necessary repairs.
- We'll identify the problem and inform you of next steps to resolve it.
- If a leak is confirmed, our service partner will attend and make the repair. Everything should now be working and back to normal.
- When the ground is ready, they'll make the surface reinstatement permanent (for instance the pavement or road, see examples below), leaving everything as we found it.
