Clark Drainage provides experienced environmental drainage services to commercial properties across the UK.
Your drainage system doesn’t just carry wastewater away from your building. It connects directly to the public sewer network, local watercourses, and groundwater.
What goes down your drains matters, and if the wrong thing reaches the wrong place, your business faces fines, prosecution, clean-up costs, and environmental damage that can take years to recover from.
Environmental drainage services cover everything your business needs to manage its drainage responsibly: interceptor cleaning, trade effluent compliance, pollution prevention, spill response, and ongoing monitoring.
It’s the overlap between keeping your drains working and keeping your business on the right side of environmental law. Contact our trusted team today to learn more about our services.
What are environmental drainage services?
Environmental drainage services focus on the environmental impact of your commercial drainage system, not just whether water flows through it.
Standard drain cleaning and drain clearance keeps your pipes clear. Environmental drainage goes further by ensuring that what leaves your site through the drainage network meets legal standards and doesn’t contaminate the sewer system, surface water, or surrounding land.
It also covers drain repair, drain survey work, gutter cleaning, and pump station maintenance where these relate to environmental compliance.
Our cleaning services include:
- Managing oil interceptors and grease traps
- Monitoring trade effluent discharges to keep you within your consent limits
- Responding to pollution incidents
- Maintaining documentation that proves your business takes its environmental obligations seriously
- Sewage treatment plant maintenance
- Septic tank system servicing
- Maintaining pump stations
For most commercial properties, environmental drainage sits across several regulations at once.
Getting it wrong isn’t just bad practice. It’s a criminal offence that can result in unlimited fines.
Why businesses need environmental drainage management
The Environment Agency and SEPA (Scottish Environment Protection Agency) are increasingly active in enforcing pollution prevention.
Water companies have the legal power to prosecute businesses that cause blocked drain incidents or contamination in the public sewer.
Fines for environmental pollution offences are significant, and directors can be held personally liable. Drainage problems left unmanaged become drainage issues that attract regulatory attention.
But enforcement isn’t the only reason to take environmental drainage seriously.
Insurance companies are also tightening their requirements around pollution liability.
The cost of getting it wrong
A single pollution incident from a blocked drain or overflowing interceptor can trigger an Environment Agency investigation. Any clean-up bill running into thousands of pounds, and potential prosecution.
Damaged drains that leak sewage into the ground create the same risk.
If contaminated water reaches a watercourse, the penalties increase substantially. And once your business has an environmental enforcement record, it follows you through tender processes, insurance renewals, and regulatory inspections for years.
Proactive environmental drainage management costs a fraction of what a single incident costs to resolve.
Regular interceptor cleaning, scheduled drain jetting, and proper trade effluent monitoring catch problems before they become prosecutions.
Our environmental drainage services
At Clark Drainage, we provide a full range of environmental drainage solutions and specialist drainage services for commercial and industrial properties.
Each service can be delivered as a one-off visit or as part of a planned waste management and drainage programme tailored to your site’s specific risks. Our range of services covers every aspect of environmental drainage for commercial properties.
Interceptor and oil separator cleaning
Oil interceptors (also called oil separators) are fitted to surface water drainage systems to prevent hydrocarbons from reaching watercourses or the public sewer. They’re required on sites where fuel, oil, or other hydrocarbons could enter the drainage system, including petrol stations, vehicle workshops, car parks, industrial yards, and distribution centres.
Interceptors only work if they’re maintained. Silt accumulates in the base, oil collects on the surface, and the separation chambers gradually lose capacity.
We clean and empty interceptors using our vacuum tanker fleet as specialists in liquid waste removal, dispose of the collected waste at licensed facilities, and provide the documentation you need to demonstrate compliance.
Grease trap and FOG management
Fats, oils, and grease from commercial kitchens are responsible for around 75% of sewer blockages in the UK.
If FOG from your premises causes a blockage in the public sewer, your business can be prosecuted under the Water Industry Act 1991.
We empty grease traps, jet the connecting pipework, and dispose of the waste responsibly through licensed carriers with our commercial grease trap cleaning service.
Trade effluent management
If your business discharges anything other than domestic sewage into the public sewer, you need a trade effluent consent from your local water company. This applies to food processing, manufacturing, vehicle washing, laundry operations, and many other commercial activities.
The consent sets limits on what you can discharge, including temperature, pH, suspended solids, and specific chemical concentrations.
We help businesses maintain compliance with their trade effluent consents through:
- regular commercial drain cleaning to prevents buildup
- CCTV drainage surveys of drainage condition
- sampling point maintenance
If you’re applying for a new consent or need to review an existing one, our drainage engineers can assess your system and advise on what changes might be needed.
Pollution incident response
When a spill or contamination event happens, the speed of your response determines the outcome.
A fuel spill contained within a bunded area is manageable. The same spill reaching a surface water drain and flowing into a watercourse is an environmental incident that triggers investigation and potential prosecution.
Our emergency drain response team is available 24/7, 365 days a year for pollution containment and clean-up.
We deploy vacuum tankers to extract contaminated water, use high pressure water jetting to clean affected drainage runs, and carry out CCTV drain surveys to confirm the contamination has been fully removed.
Where damaged drains have contributed to the incident, our drainage experts can carry out emergency drain repair on site.
We provide written reports documenting the incident, our response, and the verification evidence, which is exactly what the Environment Agency and your insurers will ask for.
Environmental drainage surveys and audits
A drainage survey with an environmental focus goes beyond checking for blockages and structural damage.
We map your foul and surface water drainage systems to confirm they’re connected correctly, check that interceptors and treatment systems are functioning properly, and identify any discharge points where contaminated water could reach the environment.
For businesses working towards ISO 14001 certification or responding to an audit requirement, our survey reports provide the drainage documentation you need.
We use CCTV technology to inspect the full drainage network through expert drainage surveys, produce detailed reports with footage, and flag any areas where your drainage system creates environmental risk. Our professional drainage survey reports are accepted by auditors, insurers, and regulatory bodies.
Contaminated water removal and disposal
Some environmental drainage work produces waste that can’t simply be flushed downstream.
Contaminated water from interceptors, settlement tanks, process drains, and spill clean-ups needs to be removed by vacuum tanker and transported to a licensed treatment or disposal facility.
We hold the necessary waste carrier licences and manage the full chain of custody, from extraction through to disposal, providing waste transfer notes that satisfy your duty of care obligations.
Surface water and SuDS maintenance
Sustainable drainage systems (SuDS) are increasingly common on commercial developments, and they need ongoing maintenance to function properly.
Permeable paving loses its permeability as silt fills the voids. Swales and attenuation ponds accumulate sediment. Filter drains and soakaways become less effective over time.
We maintain SuDS components as part of your environmental drainage programme, ensuring they continue to manage surface water runoff as designed and meet planning conditions.
