Why regular maintenance matters

Regular servicing of oil interceptors is essential to protect drainage systems, surrounding land, and local watercourses. As interceptors fill with oils, silt, and debris, their efficiency reduces, increasing the risk of:

  • Pollution or environmental contamination
  • Blockages and system failure
  • Breaches of environmental legislation
  • Operational downtime and costly clean-ups

Planned maintenance and scheduled emptying ensure your interceptor continues to function effectively, supporting compliance and reducing unexpected issues.

Our process

Shanahan Contracting Ltd carries out oil interceptor emptying and cleaning professionally and safely:

  • Assessment – Operators inspect the interceptor to determine condition and maintenance needs.
  • Waste removal – Oils, silt, and contaminated water are safely extracted using high-capacity tankers.
  • Chamber cleaning – Interceptor chambers are cleaned to restore separation efficiency.
  • Safe disposal – All waste is transported and disposed of at licensed facilities in line with environmental requirements.
  • Maintenance advice – We provide guidance on future servicing intervals to ensure ongoing performance and compliance.

Planned maintenance and emergency response

Our services are flexible and responsive, whether you require:

  • Scheduled emptying programmes tailored to your site usage

  • Just a quick thank you for your help in sorting our drainage issue and for the outstanding service provided by Michael yesterday, he is a real credit to your business.

    Andrew Standalone Farm - Letchworth

  • Today believe it or not I had the privilege of having my sceptic tank emptied by a Clive from Shanahan’s Strange as it may sound as it’s not a procedure I warm to but in this case it was a necessity! Firstly initial contact with the company who immediately recognised my dilemma and gave me the next available appointment at 7.30am the next day Then on time came CLIVE huge tanker and all, down our narrow drive. Twice he had to reverse some 60 yard to let neighbours get to work and an to an emergency dental appointment Once set up he emptied the tank only to find the soil pipe was blocked, to cut a long story short he sucked, blew, sucked again and eventually power jetted the blockage away (mechanically) that is staying nearly an hour in the process In this day and age people are quick to moan and complain and seldom, give praise but rest assured in Clive you have a real gem. Nothing is too much trouble. Amazon always ask How was your delivery? How many stars, was it on time, respect of property etc etc, but NEVER have I ticked the above and beyond but with Clive that box if there was such a box I would tick it. Well done and a big thank you to Clive
