Our Commercial and Industrial Drainage Services
Clark Drainage offers an extensive range of services specifically designed for business environments, industrial settings and commercial property estates. Each service is delivered by trained specialists with experience working in high-demand environments where safety, compliance and minimal disruption are essential.
Planned Drainage Maintenance Contracts
Planned maintenance is one of the most important aspects of commercial drainage management. Regular cleaning, inspections and performance checks prevent avoidable breakdowns and help ensure your site remains compliant with environmental, hygiene and safety regulations. Our maintenance contracts are tailored to the needs of your business, taking into account usage, facility type and operational priorities.
Routine maintenance reduces the likelihood of sudden blockages, prevents costly emergency callouts and protects assets such as kitchens, production lines, communal drains and external drainage networks. Many commercial clients choose quarterly or bi-annual visits, but we can develop a bespoke schedule to match your operational requirements.
Grease Trap Cleaning and FOG Management for Restaurants and Catering Sites
Food service environments generate high levels of fats, oils and grease. If not managed correctly, FOG creates major blockages within internal pipework and external sewers, and can result in regulatory fines for non-compliance.
Clark Drainage provides professional grease trap cleaning and maintenance for restaurants, takeaways, hotels, schools, commercial kitchens and food manufacturing facilities. We remove accumulated waste, restore safe flow and help businesses meet their legal obligations regarding FOG disposal. Our service supports hygiene compliance, prevents odours and reduces costly downtime caused by blocked kitchen drainage.
High-Capacity Industrial Drain Jetting
Industrial sites require powerful equipment capable of clearing large-diameter pipes, extensive drainage networks and heavily impacted systems. Our high-capacity jetting units generate significantly more force than standard domestic equipment and are suited to factory floors, warehouses, production plants, transport hubs and commercial estates.
This type of jetting removes sediment, scale, heavy grease deposits, production waste, silt and root intrusion from drainage systems that experience high volumes of use. It is an essential service for preventing flooding, protecting assets and maintaining business continuity in environments where drainage performance is critical.
CCTV Drain Surveys for Property Managers and Commercial Estates
Commercial clients often require formal reporting for compliance, insurance, planning or asset-management purposes. Our CCTV drain surveys provide detailed insights into the condition of underground drainage systems, enabling property managers to make informed decisions about maintenance, repairs and long-term planning.
We use high-resolution cameras capable of surveying both small internal lines and large industrial drains. The survey produces a written report, condition assessment, video footage and recommendations for remedial works where necessary. This information is invaluable for managing multi-tenant buildings, preventing disputes, meeting safety obligations and planning refurbishments or expansions.
Drain Excavation and Commercial Repair Services
Some drainage problems cannot be resolved through cleaning alone. Severe structural damage, collapsed pipes, ground movement, or long-term deterioration often requires excavation and replacement. Commercial sites, particularly older buildings or industrial facilities, frequently contain drainage systems that have been altered or extended over decades. Our engineers have the experience to identify and repair these complex structures safely and efficiently.
We handle excavation work with minimal disruption, coordinating access around your business operations and ensuring all reinstatement meets commercial standards. Whether repairing a collapsed external drain, replacing damaged manholes or installing new high-capacity pipework, we work quickly and professionally to restore full functionality.
Environmental Drainage Services
Commercial organisations must comply with demanding environmental regulations regarding drainage, wastewater management and pollution prevention. Clark Drainage helps businesses remain compliant by identifying risks, clearing blockages before they cause environmental breaches and advising on preventative measures that reduce the risk of contamination.
Food waste, chemicals, oils and general waste products must be managed responsibly. Our services support your legal obligations and help prevent costly fines, reputational damage and operational shutdowns.

Emergency Drainage Services for Businesses
When drainage failures occur, operational downtime can cost far more than the repair itself. Whether a blockage is preventing customers from entering your premises or a burst pipe is affecting production, rapid intervention is essential.
Our emergency teams operate across the UK, attending urgent commercial callouts day and night. We aim to minimise disruption by resolving the issue as quickly as possible and providing a clear plan for any further repairs required. For contract clients, emergency response can be included as part of a planned maintenance agreement, delivering substantial long-term value.
A Trusted Partner for Businesses Across the UK
Commercial drainage issues are fundamentally different from residential problems. Larger volumes of waste, more complex pipe networks, frequent usage and stricter compliance requirements create an environment where small issues can quickly escalate if not handled correctly. Clark Drainage understands these challenges and provides a level of service tailored to commercial environments.
We operate with clear communication, professional reporting, and structured repair and maintenance planning. Property managers, facilities teams and business owners benefit from predictable service delivery and transparent pricing, allowing them to manage budgets and operational expectations with confidence. Our engineers arrive fully equipped with advanced technology capable of handling complex commercial systems, including high-capacity jetting units, specialist CCTV survey equipment and commercial-grade extraction and cleaning tools.
Whether you operate a single site or manage a national portfolio, Clark Drainage provides the reassurance of a consistent service standard across all locations.
Addressing Key Business Concerns
Commercial clients have distinct priorities compared to residential customers. The following areas are central to our service delivery:
Regulatory Compliance
From grease management regulations to environmental discharge standards, businesses must adhere to a range of legal obligations. Clark Drainage helps ensure your drainage systems remain compliant through professional cleaning, accurate reporting and proactive maintenance. Our services support food hygiene inspections, environmental audits, building compliance and industry certification.
Health and Safety
Poorly maintained drainage systems can create unsafe working conditions, including slippery floors, contaminated surfaces, foul odours and exposure to harmful waste. Our engineers work safely and efficiently to eliminate risks, ensuring your premises remain safe for staff and visitors.
Environmental Responsibility
Environmental regulations around wastewater and pollutants continue to tighten. Unmanaged drainage problems can cause contamination of soil, groundwater and watercourses. Our services help businesses minimise their environmental impact by maintaining safe, reliable and compliant systems.

We understand the importance of keeping your business running, so we prioritise fast response times, efficient diagnosis and practical repairs. Planned maintenance programmes help prevent breakdowns entirely, offering peace of mind and predictable operational continuity.

Commercial Drainage FAQ
These FAQs support ranking for informational and commercial-intent searches, while strengthening Clark’s authority and trustworthiness.
Why is commercial drainage maintenance more important than residential maintenance?
Commercial systems experience significantly higher usage and often carry waste that is more complex or hazardous. Regular maintenance prevents downtime, protects staff and customers, supports compliance and ensures long-term system reliability.
How often should a business have its drains serviced?
Most commercial clients benefit from quarterly or bi-annual maintenance, though high-usage environments such as restaurants, factories and public buildings may require more frequent visits. A tailored maintenance schedule ensures compliance and reduces the risk of disruption.
Do grease traps really need professional cleaning?
Yes. Grease traps that are not cleaned regularly become ineffective, leading to blockages, foul smells and breaches of environmental and food safety regulations. Professional cleaning ensures proper functioning and compliance with local authority requirements.
Can drainage failures cause compliance or audit issues?
Absolutely. Blocked drains, FOG buildup, wastewater leaks and poor maintenance records can trigger regulatory action, including fines, closure notices or poor hygiene scores. Professional drainage support helps prevent these issues.
What causes repeated blockages in commercial properties?
Recurring blockages typically indicate underlying structural problems, inadequate grease management, incorrect pipe gradients or heavy debris accumulation. A CCTV drain survey is usually needed to identify the root cause.
Do you handle drainage issues outside working hours?
Yes. Businesses often need repairs outside trading hours to avoid disrupting customers or production. Our engineers can attend early morning, evening or overnight as required.
Can you work on large industrial drainage systems?
Yes. We have high-capacity jetting units and specialised equipment designed for industrial pipework, including large-diameter drains, production waste lines and surface drainage networks.
What happens if excavation is required on a commercial site?
We plan excavation work around your operations to minimise disruption. Safety barriers, signage and risk assessments are used to ensure workplace safety. All surfaces are reinstated once repairs are completed.
Can you provide documentation for compliance audits or insurance claims?
Yes. CCTV reports, maintenance logs, cleaning certificates and repair records can all be supplied, giving businesses the evidence they need to demonstrate compliance and asset management.
Why should a commercial property choose Clark Drainage?
Our engineers understand the pressures of commercial environments, provide rapid response times, deliver high-quality work and offer maintenance programmes designed to minimise downtime. We also support compliance, safety and environmental responsibilities.
Commercial Drainage Symptoms and Solutions
Commercial drainage systems face more demanding conditions than residential properties. High volumes of waste, continuous usage, complex pipe networks and strict compliance requirements mean that issues can escalate quickly. Below is a clear breakdown of the most common drainage symptoms experienced by businesses, along with the appropriate professional solutions.
Recurring Blockages in Kitchens or Food Preparation Areas
This is usually caused by the build-up of fats, oils and grease, or by overloaded or poorly maintained grease traps.
Best solutions: scheduled grease trap cleaning, commercial drain cleaning, high-capacity jetting, preventative maintenance contracts.
Slow Drainage Across Multiple Fixtures
When several toilets, sinks or drains slow down at the same time, the obstruction is typically located deeper in the system or within shared pipework.
Best solutions: high-capacity jetting, CCTV drain survey to identify structural faults, long-term repair planning.
Flooding in External Yards, Car Parks or Delivery Bays
Blocked gullies, debris accumulation, root intrusion or damaged surface water drains can prevent rainwater from escaping during wet weather.
Best solutions: external drain cleaning, jetting, structural repair if displacement or collapse is detected.
Foul Smells Affecting Staff or Customers
Odours often come from stagnant water trapped in the system, decomposing waste, or issues with venting and sewer connections.
Best solutions: commercial drain cleaning, grease trap servicing, inspection for damaged pipework or venting faults.
Backups in Toilets or Customer Facilities
A serious obstruction may be present in the main sewer line or shared commercial drainage network.
Best solutions: emergency drain unblocking, CCTV survey for recurring cases, targeted repairs if required.
Water Leakage, Damp or Subsidence Around the Property
Underground pipe failure can lead to soil erosion, movement, flooding or contamination.
Best solutions: CCTV drain survey, excavation and renewal of damaged pipe sections, surface reinstatement.
Production Line or Equipment Areas Experiencing Drainage Failure
Industrial processes often generate waste that standard drains cannot safely handle.
Best solutions: high-capacity industrial jetting, tailored commercial maintenance schedules, redesign of drainage routes where required.
Compliance Failures Identified During Audits
Issues such as grease trap non-compliance, wastewater mismanagement or blocked drains can result in warnings or fines.
Best solutions: routine compliance-focused maintenance, documented cleaning, survey reports suitable for audit evidence.
This clear mapping of symptoms to solutions helps commercial clients understand the urgency of action required and guides them towards the most effective service option.
