A burst water main is one of the most urgent plumbing and drainage emergencies you can face. It can cause flooding, water contamination, and property damage within minutes. Portsmouth Drains24 provides a 24-hour emergency call-out service for burst water mains and underground pipe repairs—available across Portsmouth and surrounding areas.
💧 What Causes a Burst Water Main?
Burst mains can occur for several reasons:
- Ageing or brittle pipes – especially older cast iron or pitch fibre systems.
- Ground movement or freezing conditions – shifts or frost can crack pipes.
- Heavy vehicle traffic above buried mains – pressure can weaken pipe integrity.
- Tree root intrusion – roots force their way into joints, causing breaks.
Left untreated, a burst main can lead to:
- Major flooding
- Foundation damage to buildings
- Water supply disruption
- Expensive repair bills
⚖️ Who is Responsible for Water Main Repairs?
In the UK, water main responsibility is generally split between the water company and the property owner:
- Water Company Responsibility – Public water mains in the road or pavement are usually maintained by the local water supplier (in Portsmouth, this is typically Portsmouth Water). If the burst occurs on their main, they are responsible for repair.
- Property Owner Responsibility – Once the pipework branches off the public main and enters private land, you as the property owner are responsible for any repairs. This includes supply pipes that run under your driveway or garden before reaching your home.
Tip: If you’re unsure, a quick CCTV inspection from Drains24 can confirm the location and point of damage so you know exactly who is liable.
