Leaks on public pipes

We look after the public water pipes under roads and pavements.

Over 95% of leaks are never seen by customers as they’re often deep underground. Our field teams work 24/7 to locate as many leaks as possible.

On average, we're fixing more than 1,000 leaks per week. You can help us by reporting public leaks when you see them.
