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
  • One-off cleaning and deep maintenance
  • Emergency call-outs for blocked or overflowing systems
  • Out-of-hours support to minimise operational disruption

  • I just wanted to say what a fantastic service we had yesterday. The gentleman that came to empty the tank negotiated the well and narrow driveway brilliantly!

    And the drain survey team were equally fantastic! Courteous and really helpful; involving us (we were both very curious!) as much as we wanted!

    What a brilliant team to have come to our property! We will most certainly be coming back to you for any future needs.

    Thank you.
