Spill containment berms are designed to provide reliable secondary containment and spill control in a variety of applications. Because berms are typically designed to perform in particular working contexts, it’s important to consider design differences before selecting a berm. One design feature that affects both spill capacity and performance is the size of a berm’s wall.
Standard berms are versatile berms that often incorporate drive-over features for maximum accessibility. Drive-over berms are designed to allow vehicles and equipment to enter from any side of the berm without damaging it. Conversely, high-wall berms are used to provide secondary containment for stationary equipment such as metal or poly tanks, generators, transformers, IBCs, oil and refueling equipment, and more. Standard berms and high-wall berms are also designed to meet different spill volume requirements and to function in certain applications.
Basic Concepts is the industry leader in secondary containment and spill control solutions designed for industrial and commercial facilities. We offer a wide range of standard and high-wall berms that are ideal for use in a variety of working conditions and contexts. To help you find the berm that is right for you, here is a look at some of the berms available from Basic Concepts, as well as an overview of spill volume calculations.
How to Calculate the Correct Spill Capacity
The size of a berm’s wall determines its overall spill capacity—or the total volume of liquid that the berm is able to safely contain. This means that it’s important to consider your facility’s spill capacity needs when trying to find the berm that is right for you. To calculate a standard or high-wall berm’s spill volume, follow these simple steps:- List the containers. List the containers that will be in the secondary containment area.
- Identify the largest. Determine the volume of the largest single container in the list – then add 10 percent freeboard volume.
- Convert gallons to cubic feet. Convert the gallon volume into cubic feet units using this formula: cubic feet = gallons / 7.48.
- Calculate the area. Use the berm wall height to convert your volume measurement into an area required using this formula: area = volume/height.
- Determine the size. Calculate a length and breadth that fits into the available workspace.
- Find the right-sized container. Select a standard berm that meets your calculated needs.
