Dealing with sewer flooding

Sewer flooding is the most unpleasant thing our customers can experience and we make responding to it our top priority. Thankfully these incidents are infrequent.

Always stay safe

  • Where possible do not walk through flood waters.
  • Flood waters can contain dilute sewage if the sewer network. There could also be other risks such as syringes.
  • Manhole covers may have been displaced in flooded areas which you could fall down causing a risk of injury and drowning. Be very careful as you might not be able to see them in flooded areas.
  • Don't attempt to unblock sewers yourself. You'll be putting yourself at risk and you might make things worse. Please wait and allow our trained technicians, who possess the correct equipment, to deal with the problem.
  • If you see anything that looks unsafe, contact us immediately.

What you need to do

If the problem is one for you (or your landlord) to resolve, make sure you understand the costs as these can escalate quickly when dealing with broken underground pipes.

In all instances of flooding to your home, you must make your insurance company aware, so they can start the process of getting your home back to normal.

If you're in doubt what the cause of the problem is, let us know and we'll try to help.

What can I do to help?

One of the most common causes of sewer flooding is a ‘soft blockage’. These blockages are usually caused by wipes being flushed down the toilet and cooking fat being poured down the sink.

We developed our Bin it. Don't block it campaign to combat this and help customers avoid kitchen calamities and bathroom blockages.

How do you deal with sewage flooding?

A small number of properties are at particular risk from flooding due to overloaded sewers, and we’re investing in a programme to reduce this. We’ll let you know if your property is on our risk register, and keep you up to date on our progress. Unfortunately, in extreme weather conditions, such as major storms, we can’t guarantee to prevent sewage flooding, even if we respond quickly.

Where an incident occurs which could result in a property being flooded, we’ll send a representative to assess the problem as quickly as possible. If sewage has entered your property, we’ll treat this as a priority.

What causes a sewer to flood?

There can be a number of causes, like:

  • The sewer is too full.
  • A blocked or collapsed sewer.
  • A pumping station failure.

Tree roots may cause damage to sewers, and problems may also happen if things go into the sewer that don't belong there like wipes, fats, cotton buds, sanitary items and builders’ rubble.

Flooding can also happen when there's exceptional rainfall, rivers overflow or if you have internal plumbing issues.

What we’re doing to prevent future flooding

We're continuing to invest in our pipes and network to reduce the flood risk.

Due to the complex nature of flooding (for example interaction between highway drainage, sewers and rivers), multiple agencies are often responsible for managing flood risk. We are working in partnership with other agencies to tackle flood risk more effectively.

We're also working with our customers across the region to help reduce the number of blockages on the sewer network which can often be a cause of flooding.
