Drip Control: How to Prevent Leaks, Contain Drips and Protect Your Site

Drip control is the practical answer to a common workplace question: how do you stop small leaks becoming slip hazards, pollution incidents, equipment damage, and expensive clean-up jobs? In factories, workshops, yards, loading areas, generator locations, plant rooms, fuel handling points, and maintenance areas, even a slow drip can build into a bigger spill if it is not controlled early. Good drip control uses the right drip trays, secondary containment, absorbents, drain protection, inspection routines, and spill response equipment to keep liquids where they belong.

At SERPRO, drip control sits within a wider spill management approach that includes drip and spill trays, drain protection, leak diverters, secondary containment, spill kits, and application-specific solutions for oils, fuels, chemicals, plant and industrial workplaces.^[1]

What is drip control?

Drip control means stopping drips, leaks and minor losses at source, catching them before they spread, and making sure they do not reach floors, drains, walkways, work areas, stored materials or the wider environment. It is a core part of spill prevention, spill containment and pollution prevention.

In simple terms, drip control products and procedures are used to:

• catch small leaks beneath machinery, pumps, drums, generators, pipework and dispensing points
• reduce slip risks caused by oil, fuel, chemicals, water and contaminated residues
• prevent drips and overfills from reaching drains, interceptors and surrounding ground
• support cleaner, safer and more compliant storage and handling areas
• reduce the chance that a minor leak becomes a reportable spill event

Why is drip control important?

A common question is: if the leak is only small, does it really matter? The answer is yes. HSE notes that even a tiny amount of contamination on a floor can create a real slip problem, and specifically identifies leaks and spills as sources of contamination while recommending controls such as drip trays.^[2] HSE guidance on secondary containment also explains that drip trays are used beneath equipment liable to small leaks and are intended to stop liquids spreading to other plant areas, sumps and drains.^[3]

From an environmental perspective, GOV.UK guidance for businesses states that containers holding potentially polluting materials should have secondary containment such as a drip tray or bund, together with inspection, maintenance and response planning.^[4] For oils in particular, GOV.UK guidance is clear that secondary containment is required to catch leaks, and that drip trays are commonly used for drums and other suitable containers.^[5]

What problems does drip control solve?

Problem: Small leaks under machines are often ignored because they do not look serious.

Solution: Put a correctly sized drip tray or spill tray beneath the leak point, remove collected liquid safely, and investigate the source before the problem grows. This is one of the simplest ways to control recurring drips from pumps, hoses, valves, engines, drums and plant.^[3]

Problem: Drips during filling, decanting or dispensing create contamination around storage and transfer points.

Solution: Use drip trays at fill points, under dispensing areas, and beneath containers and ancillaries where leaks or overfills may occur. GOV.UK guidance for oil storage specifically requires a drip tray for certain remote filling arrangements and highlights secondary containment for containers and associated equipment.^[5]

Problem: Liquids can move quickly across hard surfaces into drains.

Solution: Combine drip control with drain protection, absorbent socks, and nearby spill kits so a small leak can be intercepted before it becomes a wider pollution incident.^[4]

Problem: Staff know there is a leak, but nobody deals with it quickly.

Solution: Create a visible inspection and response routine, position absorbents and trays where leaks are likely, and encourage immediate action when a drip or leak is spotted. HSE’s contamination guidance supports a rapid “see it, sort it” approach.^[2]

Where should drip control be used?

Businesses often ask: where do drip trays and drip control products make the biggest difference? Typical drip control locations include:

• beneath drums, small containers and dispensing taps
• under pumps, valves, flanges, couplings and flexible hoses
• at fuelling points and generator locations
• under hydraulic equipment, compressors and mobile plant
• in workshops, maintenance bays and service vehicles
• in chemical storage and handling areas
• near loading bays, decanting points and transfer stations
• where equipment is known to weep, drip or release residue after use

SERPRO’s wider spill management content also frames drip control as part of practical spill prevention and containment in demanding industrial environments, including operations where oils, fuels, bitumen and site contamination need active management.^[6]

What is the difference between a drip tray, spill tray, bund and secondary containment?

This is one of the most important drip control questions because the wrong product can leave a site under-protected.

Drip tray / spill tray: usually used for small leaks, drips and minor overfills beneath equipment or smaller containers.

Bund / bunded system: a larger secondary containment structure designed to hold significant leaks or container failure.

Secondary containment: the general term for the second line of defence used to catch spills, drips, overfills or leaks before they escape into the workplace or environment.

GOV.UK guidance explains that secondary containment is normally either a drip tray or a bund, depending on the type of container and application. It also states that fixed tanks must be bunded rather than placed on a drip tray alone.^[5]

How big should a drip tray be?

Problem: Businesses buy a tray based only on footprint, without checking capacity.

Solution: Match both the tray size and tray capacity to the liquid volume, container type, and realistic leak scenario.

For oil storage, current GOV.UK guidance says the secondary containment for a drum, usually a drip tray, must have a capacity equal to or greater than one quarter of the drum it is holding. If the tray holds more than one drum, it must hold at least one quarter of the combined capacity of all drums it is designed to hold.^[5] GOV.UK also states that single fixed tanks, IBCs and mobile bowsers require 110% secondary containment capacity, and fixed tanks must be bunded.^[5]

For broader pollution prevention, GOV.UK guidance for businesses recommends at least 25% secondary containment for storage containers up to 205 litres and at least 110% for storage containers over 205 litres.^[4]

That means a drip control assessment should consider:

• what liquid is involved
• whether the tray is for drips only or for loss of contents
• the number and size of containers
• whether the liquid is oil, fuel, chemical, coolant or mixed contamination
• whether the tray needs a grid, support platform or chemical resistance
• whether the application really needs a bund or other containment instead

Which liquids need drip control?

Another common question is: is drip control only for oil? No. Drip control can be needed for:

• diesel and other fuels
• lubricants and hydraulic oils
• coolants and process liquids
• chemicals and cleaning fluids
• waste liquids and residues
• water mixed with oils, dirt or contaminants

The right absorbents and clean-up method depend on the liquid involved. Where the product is oil or fuel, oil and fuel spill kits and oil-selective absorbents are typically the best match. Where the liquid is unknown or hazardous, a dedicated chemical spill kit is often the safer choice.^[7]

How does drip control improve workplace safety?

Drip control improves workplace safety by reducing floor contamination, lowering slip risk, limiting contact with hazardous liquids, and making leak points visible before failures escalate. HSE’s contamination guidance is explicit that clean, dry floors are safer and that controls such as drip trays should be used to stop contamination reaching the floor.^[2]

Drip control also supports safer housekeeping. Instead of reacting only after a spill spreads, businesses can put control measures directly under known risk points. This makes routine maintenance, inspection and clean-up quicker and more consistent.

How does drip control support environmental compliance?

Drip control helps businesses answer another critical question: how do we stop a drip becoming a pollution incident? The practical answer is to combine secondary containment, routine inspection, proper labelling, segregated storage, drain protection and a documented response plan. GOV.UK guidance for pollution prevention says businesses should have a pollution incident response plan and ensure containers are in good condition, clearly marked, and provided with suitable secondary containment.^[4]

Where waste or hazardous materials are involved, GOV.UK guidance for permitted facilities also requires adequate bunding of storage areas and control of run-off, reinforcing the importance of containment and segregation in higher-risk settings.^[8]

What products work best for drip control?

Problem: One product alone rarely solves every leak scenario.

Solution: Build drip control as a layered system.

• Drip trays and spill trays for routine leaks, drips, minor overfills and protection beneath containers or equipment
• Secondary containment for larger volumes, vulnerable storage points and higher-risk applications
• Drain protection to stop escaped liquid entering drains or water systems
• Spill kits for immediate response if a leak spreads beyond the tray
• Leak diverters where overhead ingress or roof leaks are part of the site risk
• Absorbents and absorbent stations for quick, visible access to pads, rolls and socks in leak-prone areas

This layered approach also supports the broader SERPRO spill management model, where drip control is not treated as a stand-alone product but as part of site-wide spill prevention and spill response.^[6]

What should a good drip control routine include?

A good drip control system answers the operational question: what should staff actually do day to day?

• inspect drums, pipework, valves, hoses, pumps and storage points regularly
• position drip trays beneath known leak points and transfer areas
• check trays for damage, overfilling or incompatibility with stored liquids
• remove collected liquid and used absorbents safely
• keep drains identified and protect them where leaks could travel
• store suitable spill kits close to likely risk areas
• label substances clearly and separate incompatible materials
• record recurring leaks so maintenance tackles the root cause
• include drip control in housekeeping, inspections and incident response planning

These measures reflect the current direction of official UK guidance, which emphasises inspection, maintenance, response planning, segregation and suitable containment.^[4]

What is the best drip control solution for generators, plant and mobile equipment?

Generators, mobile plant and service equipment often create intermittent leaks that are easy to underestimate. In these cases, drip control usually works best when trays are portable, robust and sized for the equipment footprint, with absorbents and a small spill kit nearby. This is especially useful where oils, fuels or hydraulic fluids may drip during operation, refuelling, servicing or transport.

SERPRO’s product range includes general drip trays and application-specific tray options, making it easier to match the tray to the equipment and working environment.^[1]

When is a drip tray not enough?

Problem: Some sites rely on a small drip tray where a larger containment system is clearly needed.

Solution: Step up to bunded or broader secondary containment where volumes, risks or regulations demand it.

A drip tray may not be enough where:

• the container volume is too high for simple tray control
• fixed tanks are involved
• multiple containers are stored together
• catastrophic failure rather than routine dripping is the design case
• there is significant risk to drains, watercourses, stock or the public
• chemical compatibility, fire risk or waste regulation requirements are more demanding

Official UK guidance makes this distinction clearly: trays are suitable in many applications, but fixed tanks must be bunded and larger storage arrangements require appropriately sized secondary containment.^[5]

How do you choose the right drip control products?

If you are choosing drip control products, start with these questions:

• What liquid could leak or drip?
• Is the issue a small routine drip, a transfer spill, or full container failure?
• What is the required containment capacity?
• Does the tray need chemical resistance or a grid platform?
• Could escaped liquid reach a drain or sensitive area?
• Do staff need absorbents and spill kits at the same point?
• Would a bund, spill pallet or wider secondary containment be more appropriate?

For many sites, the most effective answer is a combination of drip trays, drain protection, spill kits, and secondary containment rather than a single product on its own.

Need help with drip control?

If your question is how do we improve drip control on our site?, the starting point is to identify where liquids are stored, transferred, used and likely to leak. Then match the risk to the right level of tray, containment, absorbent and spill response product. A good drip control strategy helps reduce slips, improve housekeeping, protect drains, strengthen environmental compliance and lower the cost of preventable leaks.
