Hydrocarbon Contamination Removal

Hydrocarbon Contamination Removal

Hydrocarbon contamination removal is a specialist service for sites affected by fuel, oil, diesel, lubricants and other hydrocarbon pollutants. Whether it’s a spill, an interceptor failure, or long-term build-up in chambers and pipework, hydrocarbon contamination can create serious risks: blocked drainage, odours, safety hazards, and potential environmental non-compliance.

At ICE Drainage, we support commercial sites with hydrocarbon contamination response and remediation  including forecourts, car washes, depots, workshops, industrial yards and facilities-managed portfolios. We focus on practical containment, safe removal, and getting your drainage assets back under control.

Call ICE Drainage on [PHONE] or email contactus@icedrainage.co.uk to book hydrocarbon contamination removal or request urgent support.

Hydrocarbon contamination removal for commercial sites

Hydrocarbons don’t behave like normal wastewater. They can:

• Float and spread across chambers and separators

• Coat pipework and reduce flow capacity

• Create strong odours and vapour risks

• Contaminate silt and debris, increasing disposal complexity

• Cause interceptors/separators to fail or bypass

• Increase the risk of pollution incidents and enforcement action

If you suspect hydrocarbons are entering your drainage system, fast action reduces both cost and risk.

Common causes of hydrocarbon contamination

We’re often called out for:

• Fuel spills on forecourts and in service yards

• Oil leaks from vehicles, plant or storage areas

• Workshop wash-downs entering surface water drainage

• Interceptor failure due to lack of maintenance or overload

• Silted catchpits causing hydrocarbons to spread upstream

• Historic contamination in chambers and pipework

• Odour complaints linked to oily residues

Even small, repeated leaks can build up over time, especially where catchpits and interceptors aren’t maintained.

Signs you may have hydrocarbon contamination

Book an assessment if you notice:

• Rainbow sheen or oily film in gullies, catchpits or chambers

• Strong fuel/oil odours around drainage points

• Unusual discolouration of water in chambers

• Sludge build-up that looks oily or sticky

• Standing water on site with visible contamination

• Repeat blockages or restricted flow near interceptors

• Concerns raised during audits, inspections or handovers

If there’s an active spill or immediate risk, call [PHONE] for urgent support.

Our hydrocarbon contamination removal process

Every site is different, but our approach is consistent: identify the source, contain the risk, remove contamination, and reduce the chance of repeat incidents.

1) Initial assessment & risk review

We assess:

• Where contamination is present (gullies, channels, catchpits, interceptors, pipework)

• Likely source and flow route

• Immediate risks (odour/vapour, overflow, blocked drainage, spread across site)

• Condition and capacity of interceptors/separators

2) Containment and control

Where required, we help isolate affected areas and reduce spread through the drainage network.

3) Removal of contaminated liquids, sludge and debris

We remove hydrocarbon-contaminated contents from:

• Catchpits and silt traps

• Petrol/oil interceptors

• Wash bay separators

• Chambers and sumps

This typically includes oily water, sludge, and silt that has absorbed hydrocarbons.

4) Cleaning and restoration

We clean affected chambers and, where appropriate, support follow-on works such as:

• Drain jetting / line cleansing to remove residues in pipework

• Targeted cleaning of channels and gullies

• Recommendations for repairs or upgrades if assets are damaged or undersized

5) Reporting and recommendations

For facilities management and compliance records, we can provide clear notes on:

• Areas affected n- Observations and likely causes n- Recommended maintenance frequency n- Follow-on actions to reduce repeat risk

Interceptors and separators: why they matter

On many sites, the interceptor/separator is the key control point. If it’s:

• Overloaded with silt

• Not emptied on schedule

• Damaged or bypassing

• Incorrectly sized

…then hydrocarbons can pass downstream or spread upstream.

We can assess your interceptor performance and recommend a practical maintenance programme to keep it working properly.

Planned maintenance to prevent repeat contamination

Hydrocarbon contamination is often a symptom of poor drainage maintenance. A planned programme can include:

• Regular channel and gully cleaning

• Catchpit and silt trap emptying

• Interceptor inspections and servicing

• Sampling and compliance inspections

• Drain jetting where build-up is likely

For multi-site operators and FM providers, we can standardise schedules and reporting across your portfolio.

Why choose ICE Drainage?

Hydrocarbon contamination needs a contractor that understands interceptors, separators, and commercial drainage risk.

With ICE Drainage, you get:

• Commercial-first response for forecourts, depots and industrial sites

• Experience with interceptors, catchpits and contamination issues

• Clear reporting for FM and audit trails

• Capability to deliver follow-on works (jetting, investigations, repairs, planned maintenance)

Hydrocarbon contamination removal FAQs

Can you help after a fuel spill?

Yes. We can attend to assess affected drainage points, remove contaminated contents, and recommend next steps to reduce spread and future risk.

Will you need to clean the interceptor as well?

Often, yes  especially if contamination has entered the drainage network. We’ll advise after assessment.

Can you help prevent this happening again?

Yes. We can set up a planned drainage maintenance programme covering catchpits, channels and interceptor servicing.
