Sewage Emergency: what the job involves
A sewage emergency happens when waste backs up instead of draining away. You might see it rising in a toilet, a shower tray or an outside drain. The smell is usually the first sign. Because sewage carries germs, it needs clearing quickly and carefully.
Keep children and pets well away from the area. Stop using every toilet, sink and appliance, since each one adds more waste to the blocked drain. If you must touch anything, wear gloves and wash your hands well afterwards. Then send an urgent request so we can pass it to a local engineer.
The engineer finds where the blockage sits by checking the manholes, because the water level shows it. They then clear it with rods or a jetter and flush the drain. If the blockage is in a public sewer or a shared lateral drain, it is the water company's job. In that case, the engineer tells you to report it to Severn Trent.
How the job goes
- 1. Find the blockage The engineer lifts the manhole covers to see where the waste stops.
- 2. Clear the drain They clear it with rods or a jetter and flush the run.
- 3. Advise on clean-up They explain any repair needed and who is responsible.
Typical costs
UK price guides put drain unblocking at about £80 to £250 outside London (Fantastic Services and UK Plumber Spot, 2026). Emergency visits at night often cost more. If the blockage sits in a public sewer, the water company should clear it at no cost to you. These are typical ranges, and you can ask your engineer to confirm the price before they start.
Around Wolverhampton
Many homes around Wolverhampton share a drain with their neighbours. Since October 2011, most shared lateral drains in England belong to the water companies. As a result, a sewage backup in a shared drain may be Severn Trent's job to clear. The engineer can tell you where the blockage sits.
Sewage Emergency: frequently asked questions
What should I do if sewage comes up in my house?
Stop using all water and keep people and pets away, since sewage carries germs. Wear gloves if you must touch anything. Then send an urgent request, and report it to Severn Trent if neighbours have the same problem.
Who pays to clear a sewage blockage?
You pay if the blockage is in a drain that only serves your home. However, the water company pays for shared lateral drains and public sewers. Citizens Advice explains this split.
Is sewage in the garden an emergency?
Yes, because it carries germs and can spread. Keep children and pets away and stop using water. Then send an urgent request.
Will my insurance cover sewage damage?
Many policies cover some damage from escaping water or sewage, although terms vary. Take photos before cleaning up. Then check your policy or call your insurer.
