How to avoid blockages in a commercial kitchen
Blocked pipes can cause bad smells, fatbergs and sewer flooding - problems that don't just impact you and your business, but your neighbours and others in your local community too.
Clearing thousands of blockages each year
Every year, we clear around 45,000 blockages. Often these are down to a build-up of fats, oil and grease or inappropriate items being flushed down the toilet.
We work closely with our partner organisation Environmental Compliance and Services (ECAS), to help local businesses protect the sewer system, and educate owners and operators about how to safely dispose of fat, oil and grease.
What causes blocked drains in commercial kitchens
If you pour fat, oil or grease down your sinks and drains, over time the build of up these fatty deposits in sewers creates a large blockage, known as a fatberg.
These fatbergs prevent sewage from moving along the system to the treatment centres, creating a backlog.
Fatbergs can lead to:
- unpleasant smells coming from the drains around the area
- sewer flooding around your business or your neighbours’ properties
Sewer flooding and bad smells can lead to unhygienic conditions, causing kitchens to close and food establishments to lose revenue while the cause is investigated and appropriate action taken.
How you can stop fat, oil and grease entering the sewer
There are some simple steps you can take to help prevent fat, oil and grease entering the sewer system and help protect you and your neighbours from sewer flooding.
Get a properly sized grease trap
It’s really important you install a grease trap that’s the right size for your kitchen’s needs.
Before you install a grease trap, call us on 01217 671 335 to discuss it with us first. Our expert team will be able to give you advice about where to put your trap, how big it needs to be and check that’s it’s a suitable trap for your business.
Techniques to avoid
Pouring boiling water down the sink to try and dissolve fat and grease does not work. It simply pushes the problem further down the drain.
That fat, oil and grease might temporarily dissolve in the boiling water and get down your plughole, but it will just take a bit longer to cool, and contribute to a blockage a little bit further down the line. It will still have an impact on your business and your neighbours.
Dispose of your food and cooking waste properly
Empty and clean your grease trap regularly
Your grease trap will fill up on a regular basis. It’s important you empty the grease trap when it’s full or fat oil and grease will continue to enter the sewer network.
When your trap is full, empty it into air-tight containers and store them away from drains to prevent spills and leakages getting into the sewer network.
You can then arrange for the containers to be collected by approved waste contractors who will recycle it to be used as bio-fuel.
It is a legal requirement to dispose of your fat, oil, grease and food waste using a licensed waste carrier.
Your legal requirements
There are several different laws that require catering businesses to manage the disposal of fat, oil and grease correctly, including:
- Water Industry Act 1991
- Environmental Protection Act 1990 - Duty of Care
- Environmental Protection Act 1990 – Statutory nuisance
- Animal By-products Regulations EC 1974/2002 (ABPR)
- Building Act 1984
- Food Safety Act 1990
