Oil Interceptor Maintenance – How Often Should They Be Cleaned?

An oil interceptor is an extremely useful piece of equipment that separates oil and water to ensure that pollution of our environment is kept to an absolute minimum. They are usually located at places like garages, car parks and construction sites, where there is likely to be a large number of vehicles and therefore a high chance of oil or petrol getting onto the ground.

Should that oil combine with rain or other water, there is a risk of it running off into the drainage system or the surrounding area and doing significant damage. By trapping the runoff and separating the oil and water, the water can be returned to the environment while the oil can be taken away and disposed of safely.

In this regard, an oil interceptor carries out a similar process – and operates in a very similar way to – a septic tank. And like a septic tank, to keep functioning effectively and safely, it requires regular maintenance and cleaning.

Why is oil interceptor cleaning needed?

An oil interceptor that is not regularly cleaned or properly maintained will eventually stop functioning properly and the contents could well flood into the local environment. At that point, there is the very real risk that oil and petrol will be allowed to enter local soil and water channels, where it could pose a significant risk to animals, plants and even human health.

Without regular maintenance of your oil interceptor, you might also be considered to be putting local groundwater at risk of pollution and subject to legal action under the Water Pollution Act 1997 & 2000 or the Dangerous Substances Act 1972.

What oil interceptor maintenance is needed?

When one of our technicians arrives at your premises to carry out maintenance on your oil interceptor, there are a number of important tasks they will carry out. These include, but are not limited to:

  • Checking the integrity of both the interceptor and any working parts
  • Checking contaminant levels – and if necessary, removing and disposing of them safely
  • If there is one, checking the coalescing device and replacing if necessary
  • Servicing electrical systems – these may include alarms and the interceptor management system
  • Checking the operation of the automatic closure device
  • Maintaining written records covering maintenance and servicing, together with a log of any incidents that might have occurred
  • And a lot more!

Three key benefits of oil interceptor cleaning & maintenance

  • Keeping your business safe from prosecution under environmental regulations
  • Preventing pollution of the local environment
  • Saving money – regular oil interceptor cleaning is cheaper than having to dispose of oil that has been allowed to accumulate for a long time

How often is oil interceptor maintenance needed?

It is advisable to have an accredited professional service your oil interceptor at least every three to six months. However, that should be increased in the event of heavy rain (which may flood your interceptor or cause extra contaminants to be washed in) or in areas where there are particularly high levels of traffic.
