Urgent drainage problems

Emergency drain unblocking in Derby

An overflowing drain, sewage backing up or a blockage affecting essential facilities can need prompt attention. This page helps you reduce the immediate mess, identify responsibility and explain the symptoms clearly to a drainage professional.

When this service may be useful

  • Wastewater is backing up

    Toilets, gullies or floor-level drains are overflowing or rising when water is used elsewhere in the property.

  • More than one fixture is affected

    A toilet, sink and shower all draining badly can indicate a blockage further along the drainage run rather than one local trap.

  • The problem keeps returning

    A blockage that repeatedly comes back may need more than simple clearance and can justify further investigation.

  • A business cannot operate normally

    Restaurants, shops, offices and other premises may need rapid assessment where drainage failure affects hygiene or trading.

Good to know

If sewage has escaped, avoid direct contact and keep children and pets away from the contaminated area while you arrange appropriate help.

What usually happens

A sensible process

  1. 1
    Reduce additional flow

    Stop unnecessary flushing, washing-machine cycles and other water use feeding the affected drain.

  2. 2
    Check the pattern

    Note which fixtures are affected and whether neighbours appear to have the same problem. This can help identify private versus public responsibility.

  3. 3
    Explain the symptoms

    Give the contractor the postcode, access information, when the problem started and whether wastewater is escaping inside or outside.

  4. 4
    Agree scope and price

    Before work begins, confirm the call-out arrangements, proposed method and any circumstances that could add cost.

Questions people ask

Frequently asked questions

Is every blocked drain an emergency?
No. A slow drain with no overflow may be manageable during normal working hours. Sewage backing up, loss of essential sanitation or an active overflow is more urgent.
Should I keep flushing to see if it clears?
If water levels are already rising or backing up, repeatedly adding more water can make the overflow worse. Stop unnecessary water use until the cause is understood.
What if several homes are affected?
That can indicate a problem beyond your private drain. Check our responsibility guide and Severn Trent’s current guidance before paying for private work.
