Sewage Backing Up or Outside Drain Overflowing?
Critical safety notice: Raw sewage contains harmful pathogens. If water is flooding your property or backing up into toilets and baths:
- STOP using water: Do not flush toilets, run taps, or use appliances.
- Keep away: Keep children, pets, and vulnerable persons away from sewage water.
- Avoid DIY rodding: Forcing rods down backed-up sewer manholes can increase risk of sewer bursts.
When is a drainage problem urgent?
A drainage issue needs prompt attention when wastewater is escaping, essential facilities cannot be used, or continued use could cause damage.
- Sewage is rising through a toilet, shower or floor drain
- An outside drain or chamber is overflowing
- The only usable toilet in the property is blocked
- Wastewater is approaching internal floors, electrics or stock
- A business cannot operate essential hygiene facilities
A slow drain that is not overflowing may still need attention, but it is usually safer to stop using it and arrange an assessment rather than wait for it to worsen.
What should you do while waiting for help?
- Stop flushing toilets and using connected taps or appliances.
- Keep people and animals away from wastewater.
- Avoid touching sewage or attempting to enter a chamber.
- Move portable belongings away from the affected area if this can be done safely.
- Ask neighbours whether their drainage is also affected.
Tell the engineer where the water is appearing, which fixtures are affected and whether the level changes when water is used.
What happens during an emergency visit?
The immediate aim is to identify the affected section, reduce the risk of further overflow and restore usable drainage where possible.
The engineer checks accessible fixtures, gullies and inspection points before explaining the proposed work and price. Clearance may use mechanical equipment or high-pressure water jetting. Flow is tested after the obstruction is removed.
If the pipe appears damaged or the blockage is outside the responsibility of the property owner, the next action will be explained.
Private drain, shared drain or public sewer?
If only one property is affected, the blockage may be in a private drain. A problem affecting several properties may involve a shared drain or public sewer managed by Yorkshire Water.
A blocked highway gully on a publicly maintained road is normally a matter for Leeds City Council. A drainage engineer can help locate the likely problem, but ownership decisions may rest with the property owner, water company or council.
Frequently Asked Questions
What should I do first if sewage is backing up?
Stop using connected drainage, keep people and animals away, avoid direct contact with wastewater and call for advice. Do not enter an inspection chamber.
Can I keep using unaffected taps or toilets?
It is safest to stop using fixtures that may connect to the affected drain. Additional water can worsen an overflow, particularly when the route is not yet known.
How quickly can an engineer attend?
Attendance depends on location, current workload, access and the nature of the emergency. The 24/7 call line can confirm current availability without promising a time before the details are checked.
Is the blockage mine or the responsibility of Yorkshire Water?
A private drain serving only one property is usually the responsibility of the owner. Public sewers and many shared drains are generally the responsibility of Yorkshire Water. The route and affected properties help indicate who to contact.
Can emergency drainage help be arranged for a business?
Yes. The site contact should explain which facilities are affected, any wastewater risk, opening hours, access arrangements and who is authorised to approve work.
