Walk through any workshop, warehouse, or factory floor and there is a good chance something is leaking somewhere. A hydraulic line dripping oil. A drum with a slow seep around the bung. A machine that leaves a puddle after every shift. These small leaks do not look like a big deal at first, but they add up fast. Slippery floors, contaminated soil, clogged drains, and fines from environmental authorities all start with drops that nobody bothered to catch.
That is where a simple piece of equipment makes a real difference.
What Exactly Is a Drip Tray?
A drip tray is a shallow container, usually made from polyethylene plastic, that sits underneath equipment, drums, or machinery to catch leaks and drips before they hit the floor. The concept is about as simple as it gets. Liquid falls, tray catches it, floor stays clean.
Most trays are made from high-density polyethylene (HDPE), which is tough, lightweight, and resistant to a wide range of chemicals including oils, fuels, solvents, and mild acids. They come in different sizes, from small units that fit under a single drum to large platform-style trays that can hold multiple containers or entire machines.
Some trays have a flat base, and others have a raised grate or grid that sits inside the tray. The grate keeps drums or containers lifted above the collected liquid, so they are not sitting in the spill. This is a small detail that makes a real difference, especially during inspections.
Where Do They Get Used?
The short answer is: almost everywhere that liquids are stored, transferred, or used. Here are some of the most common setups.
Workshops and garages are probably the most obvious. Any place that works on vehicles or machinery deals with oil, transmission fluid, brake cleaner, coolant, and plenty of other liquids. A tray under a workbench or a machine stops those slow drips from building into a slick on the floor.
Warehouses and storage areas that hold drums of chemicals, paint, lubricants, or cleaning products need something under those containers. A drum might look sealed, but over time caps loosen, seals degrade, and condensation collects. Placing drums on drip trays is one of the easiest ways to stay within environmental and safety regulations.
Fuel storage and dispensing points are another common use. Anywhere diesel, petrol, or paraffin gets stored in quantity, there should be secondary containment underneath. A polyethylene tray does the job without rusting, corroding, or reacting with the fuel.
Laboratories and mixing rooms deal with all sorts of chemicals in smaller quantities. A tray on the bench or under the mixing station catches drips during transfers, which keeps both the workspace and the workers safer.
Loading docks and transfer areas are spots where spills happen regularly. Every time a drum gets moved, tipped, or connected to a pump, there is a chance of a splash or a drip. Having a tray at the transfer point keeps those drips contained right where they fall.
Why Polyethylene Is the Go-To Material
Steel trays exist, and they have their place, but polyethylene has taken over as the preferred material for most applications. There are a few good reasons for this.
Polyethylene does not rust. A steel tray in a wet workshop will start corroding within months. A poly tray can sit in the same spot for years and look the same as the day it was installed.
It is lighter. Moving a large steel tray requires multiple people or a forklift. A poly tray of the same size can often be carried by one or two people, which means it actually gets moved when it needs to be cleaned or repositioned.
Chemical resistance is another big factor. Polyethylene handles contact with most industrial liquids without breaking down. Acids, alkalis, petroleum products, and solvents that would eat through lesser materials barely affect it.
And it is cheaper. For the same level of containment capacity, a poly tray typically costs less than a steel one, ships lighter, and lasts just as long or longer in most settings.
Sizing Matters More Than People Think
One of the biggest mistakes when buying containment trays is getting the wrong size. Too small, and the tray overflows during a spill, which defeats the whole purpose. The general rule for drum storage is that the tray should hold at least 110% of the largest container sitting on it. So if the biggest drum on the tray holds 200 litres, the tray needs to hold at least 220 litres of liquid.
For areas where multiple drums are stored, the tray should still meet that 110% rule for the single largest drum, or 25% of the total stored volume, whichever is greater. These numbers come from environmental regulations, and inspectors will check them.
Getting this wrong is not just an environmental risk. It is a compliance issue that can lead to fines, stop-work orders, or worse if a spill reaches a water source.
Maintenance and Upkeep
A drip tray that never gets emptied or checked is not much better than having no tray at all. Over time, collected liquid builds up. If the tray reaches capacity and then another spill happens, everything overflows anyway.
The fix is simple: check trays regularly and empty them when they start filling up. Collected oil or chemicals need to be disposed of properly through a licensed waste handler. Pouring accumulated liquid down a drain is illegal in most jurisdictions and exactly the kind of thing that environmental officers look for during site visits.
Cleaning the trays themselves is straightforward. A wipe-down with a rag and some degreaser handles most oil-based residue. For chemical trays, rinsing with water and checking for cracks or warping after each cleanup keeps things in good shape.
Cracks are the main thing to watch for. Polyethylene is durable, but heavy impacts, UV exposure over time (for outdoor trays), and certain aggressive chemicals can cause damage. If a tray has a crack, it needs to be replaced. A cracked tray is just a floor with walls around it.
Picking the Right Supplier
Not every supplier stocks the same range, and quality varies more than most people expect. When looking at drip tray suppliers, there are a few things worth paying attention to.
Stock range is the first one. A good supplier carries trays in multiple sizes, with and without grates, and in configurations suited to different numbers of drums. A supplier with only one or two options is probably not specialized in containment products.
Material quality is next. Thicker walls, UV-stabilized plastic for outdoor use, and properly finished edges all indicate a better product. The difference between a thin, flimsy tray and a properly made one shows up the first time something heavy gets dropped into it.
Delivery and availability count too. Spill containment is not something most sites plan months in advance. When a tray is needed, it is usually needed within days, not weeks. A supplier that keeps stock on hand and can ship quickly has a clear advantage.
Technical support is the last piece. A supplier who can help with sizing calculations, regulatory requirements, and product selection saves time and reduces the chance of ordering the wrong thing.
The Regulatory Side
In South Africa, environmental legislation under the National Environmental Management Act and its associated waste and water regulations places clear obligations on businesses that handle hazardous substances. Secondary containment, which includes drip trays, is part of meeting those obligations.
The Department of Water and Sanitation has specific requirements around preventing pollutants from reaching groundwater and surface water. A spill that soaks into soil or runs into a storm drain can trigger serious consequences, including remediation orders, administrative penalties, and criminal prosecution in extreme cases.
Having the right containment equipment on site is one of the simplest steps a business can take toward compliance. It is far less expensive than the alternative.
It Comes Down to the Basics
Catching drips and small spills before they become big problems is not complicated. The equipment exists, it is affordable, and it works. The businesses that stay out of trouble with environmental authorities and keep their workers safe tend to be the ones that get the basics right and stick with them.
