What counts as a commercial drainage emergency?

A commercial drainage emergency is any drain failure that stops a business operating safely: sewage coming up inside, toilets or kitchen drains that have stopped, or a chamber overflowing where people walk.

Typical examples:

  • Waste water rising through a kitchen floor gully during service
  • Every toilet in a washroom block backing up at once
  • A blocked drain in a care setting, school or hotel where people depend on the facilities
  • An external manhole spilling across a car park, shop front or beer garden
  • A flooded chamber or pump failure on an industrial site

A single slow basin in a back office can usually wait for a planned visit. If customers, staff or food are exposed to waste, or you cannot trade, treat it as an emergency.

What should you do while waiting for us?

Stop water going into the drains, keep people away from any spill and protect food and stock; those three steps limit the damage more than anything else you can do before we arrive.

  • Turn off dishwashers, glass washers and washing machines, and ask staff not to use sinks or flush toilets
  • Close the affected washrooms or kitchen area and put up a sign
  • Move food, packaging and stock away from any water that has escaped
  • Do not lift heavy chamber covers or put rods or chemicals into the drain
  • Take photos of what has happened, which helps with any later insurance or landlord discussion
  • Find out whether neighbouring units are affected, as that tells us a lot about where the blockage sits

If there is any risk of sewage reaching electrics, keep people clear and isolate the supply only if it is safe to do so.

What causes emergency drain failures at businesses?

Most commercial drain emergencies start with build-up that has been growing for weeks and finally stops the flow: fat in a kitchen run, paper in a washroom stack or silt in a yard gully.

Other common causes:

  • A grease trap that has gone past its emptying point and is passing fat straight into the drain
  • Sanitary products, paper towels or wipes flushed in customer toilets
  • A cracked, displaced or root-damaged pipe catching debris
  • A heavy rainfall overloading surface water drains or a combined sewer
  • A failed pump in a basement or below-ground drainage system
  • A blockage in a shared drain or public sewer that is backing up into your property

Knowing which of these you are dealing with decides whether the fix ends when the water starts moving.

How quickly can someone reach your premises?

For an emergency call-out we aim to be on site within 60 minutes of your call, 24/7, and we confirm the timing when you ring.

The exact time depends on where the site is and what else is in progress at that moment. Giving us a clear picture on the phone helps us prioritise properly: what has stopped, whether waste has escaped, whether the public are affected and whether you can keep trading in part.

If you are in Dorchester or one of the surrounding villages we cover, say so at the start of the call, along with the best way into the site at that hour.

How we handle a commercial drainage emergency

We get the drain flowing so you can trade, contain and clean up what has escaped, then establish why it happened and report back.

  • We agree on the phone what we know so far and what the visit will cost before we set off
  • On arrival we check the chambers to find where the blockage sits and whether it is in your private drain or a shared section
  • We clear it by the least disruptive suitable method, usually rodding or jetting
  • Escaped waste is contained and the affected area is cleaned down
  • We test the drain with water from the fittings that were affected
  • If the cause is not obvious, we suggest a camera survey, either straight away or at a time that suits you
  • You get a written account of what failed and what would stop it happening again

Trading first, root cause second

When a drain failure has closed a kitchen or washroom block, the first job is getting you open again; finding out why it happened comes once you are trading.

Trying to solve everything during service rarely works. A full camera survey, a repair or a long cleaning job can mean hours with areas out of use. If a temporary clear will get you through the evening safely, we do that, explain what we found and agree when to come back to deal with the cause.

Where a temporary clear would not be safe, for example because a pipe has collapsed and waste would keep escaping, we tell you plainly. That decision is yours, but it should be made with the facts in front of you.

Why containing escaped waste matters

Escaped sewage in a food or customer-facing area is a hygiene and reputational problem as well as a drainage one, and containing it early limits what has to be deep-cleaned or thrown away afterwards.

Sewage carries bacteria and viruses that cause illness, and it spreads on footwear, trolleys and mops. Closing off the area, stopping the source and cleaning out from the edge inwards keeps the contamination from moving through the building.

In a food business, any surface, equipment or stock touched by sewage needs cleaning and disinfecting or disposing of before it is used again. Your food safety procedures should already say how that is handled. If you are unsure, your local authority's environmental health team can advise.

How long does an emergency commercial call-out take?

Clearing a straightforward commercial blockage often takes an hour or two once we are on site, but a heavily fat-bound run, several blockages or a large clean-up can take considerably longer.

The time on site depends on where the blockage sits, how far the drain has backed up, how much waste has escaped and how easy the chambers are to reach. A blockage at the first chamber outside is usually quicker than one deep under a building with limited access.

We tell you what we expect once we have looked, and keep you updated if that changes. You decide whether to keep trading in part while the work goes on.

What an emergency visit can and can't fix

An emergency visit restores flow and deals with the mess. It does not, on its own, repair a broken pipe, empty an overloaded grease trap for the long term or fix a public sewer.

If a camera or the behaviour of the drain points to a defect such as a crack, a displaced joint or a collapse, that is reported with what we saw and the options for fixing it. Repairs and relining are quoted separately and only go ahead when you agree.

If the blockage is in a shared drain or public sewer, we can relieve the immediate problem where it is safe and appropriate, but the lasting fix belongs to the water company and we will tell you how to report it.

How much does a commercial emergency call-out cost?

The cost depends on the size and location of the blockage, the method needed to clear it, how much clean-up is required and whether a camera survey is added.

As a guide, most commercial blockages are cleared for between £80 and £200. A job that turns out to need excavation or a new section of pipe costs more, and is priced separately before it starts.

There is no call-out fee, and a night or weekend call-out costs the same as one on a weekday. Before we set off, you get a clear explanation of what the visit involves and what it will cost, and you agree that fixed price first. If the job turns out to be bigger once we are on site, such as a second blockage or a damaged section, we stop, show you, and agree any extra before doing it. You are never asked to pay for work you did not agree to.

Who pays: tenant, landlord or water company?

It depends on where the blockage is and what your lease says: private drains are usually the tenant's or landlord's under the repairing terms, while shared drains and public sewers are generally the water company's.

For drains within the site, the lease decides. Many commercial leases make the tenant responsible for keeping drains clear, while structural repairs to the pipework may sit with the landlord. Where a blockage was caused by misuse, such as fat or wipes, the occupier usually bears the cost.

Since 1 October 2011, sewers and lateral drains shared with other properties, and lateral drains outside the boundary, have generally been the water company's responsibility. Around Dorchester that means Wessex Water. If we find the blockage there, we tell you before you pay for it.

What happens after the emergency?

After the emergency, you get a plain account of what failed and what would stop it recurring, which may be a repair, a change to how the system is used or a cleaning interval.

The account covers where the blockage was, what caused it, what was done and anything we saw that needs attention. If footage was recorded, you get that too. It is the document your landlord, insurer or head office is likely to ask for.

If the same site has had more than one emergency, it is worth looking at why. Repeat failures usually point to a grease trap that needs emptying more often, a defect in the pipe or a pattern of use on site, and each of those has a fix that costs less than the next emergency.

How it works

Simple, transparent process

  1. 1

    Tell us what’s happening

    Call and describe what you’re seeing — a slow sink, a gurgle, a smell or standing water. It usually tells us a lot before we arrive.

  2. 2

    We find the cause

    We clear enough to get flow back, then work out why it blocked — because a drain that blocks twice has a reason.

  3. 3

    A price before the work

    If it needs more than a clear — a repair, a lining, a survey — you get the price and the reason before we start it.

  4. 4

    You see the evidence

    Where we survey, you get the footage. Where we repair, you see the before and after.

Don't let it get worse

Commercial Emergencies: common questions

Can you deal directly with a tenant rather than the landlord?
We can attend when a tenant calls, because an emergency cannot wait for a chain of approvals. Before we start, it helps to know who is authorising and paying for the work, and whether the lease or managing agent requires the landlord to be told. If the landlord is responsible under the lease, the written account of the visit gives them what they need to deal with the cost.
Can you provide documentation for compliance or insurance purposes?
Yes. After an emergency visit you receive a written account of what failed, where, what caused it and what was done, along with any footage recorded. Businesses use it for food safety records, landlord reporting, head office incident logs and insurance claims. If you need particular details included for your own procedures, tell us when you call so we can record them on the day.
What if the blocked drain is shared with other units?
In a parade of shops, an office building or an industrial estate, one drain often serves several units. If the blockage sits in that shared section, it may be the water company's responsibility rather than yours, or a cost split under the estate's arrangements. We check the chambers to establish where the problem is before charging you for clearing a drain that serves your neighbours as well.
Do you attend at night, weekends and bank holidays?
Yes. We take emergency calls 24/7, including nights, weekends and bank holidays, because commercial drains tend to fail when they are busiest: a Friday night service, a Sunday lunch or a full hotel. Ring 0330 133 1625 and tell us what has stopped, whether waste has escaped and how to get into the site.
Should staff try to clear the drain while we wait?
Plunging a single blocked sink or toilet is reasonable if it is not overflowing and staff are wearing gloves. Beyond that, it is best left alone. Lifting chamber covers can cause injury, rods pushed in from the wrong end can compact a blockage, and caustic chemicals sitting in a stopped drain become a hazard for whoever clears it afterwards.
Should we stop serving food if a drain has backed up?
If waste water or sewage has reached a food preparation, storage or service area, stop using that area until it has been cleaned and disinfected. Any food, packaging or equipment it touched should be disposed of or sanitised according to your food safety procedures. A blockage confined to an external chamber may not require closing the kitchen, but stop sending water down the affected drain.
Will business insurance pay for an emergency drain call-out?
That depends entirely on your policy. Some commercial policies cover damage caused by an escape of water or sewage, and some include business interruption, but routine blockages caused by fat or wipes are often excluded. Check the wording with your broker. Our written account and any footage give the insurer the facts about what failed and why, which helps any claim be assessed.
What should I tell you when I call about a commercial emergency?
Tell us the address and type of business, which fittings have stopped, whether waste has escaped and where, whether customers or staff are affected, and whether neighbouring units have the same problem. Mention any grease trap, pump or interceptor on site, and how we get access at that hour. Those details help us work out the likely cause and the price before we set off.
How can I tell if the problem is in the public sewer?
Lift a light inspection cover if it is safe to do so. If the chamber nearest your building is full but the one nearer the road is empty, the blockage is usually in your private drain. If the last chamber before the sewer is also full, or neighbouring premises are affected too, the problem may be in a shared drain or public sewer, which is generally the water company's to clear.
Who needs to be on site when you arrive?
Someone who can let us into the building and show us the affected areas, the location of chamber covers and any plant room, grease trap or pump. They should also be able to agree the price and any change to the work. For a night call to a closed site, a keyholder is enough, provided the person authorising the work can be reached by phone.
Do you offer accounts for landlords and letting agents?
Yes. Landlords, letting agents and managing agents can open an account with us, so emergency and routine work across their properties is invoiced on terms agreed when the account is set up. It saves a payment being taken on site each time, and gives you one record of the work done at each address.
What payment methods do you accept?
We accept card payments, bank transfer and cash. Businesses, landlords and agents that use us regularly can also arrange an account, with work invoiced on agreed terms rather than paid for at each visit. Whichever way you pay, the price for the work is agreed before it starts.
