On Bunds, Secondary Containment and Drip Trays: Learning the Basics

Several barrels of toxic waste at the dumpDiscussions usually come up regarding the several requirements to control liquid spills, primarily because of the misinterpretation of the simple terminology. They are unaware that there are massive differences between a spill containment bund, a secondary containment and a drip tray.

It’s necessary to learn about the purpose of each, along with the requirements to control particular kinds of spill permits the selection of the proper type of containment.

Spill Containment Bunds

The primary purpose of a bund is to preserve and manage the flow of liquids. A bund is exposed to the atmosphere, and commonly the elements. It is not utilised for containment, but for management of flow and retention. These are primarily used for non- or low hazardous liquids, like rainwater and slurries.

For instance, agriculture bunds are utilised to manage or control rainwater flow or to contain it for livestock watering and irrigation. Land-based industrial sites use bunds to manage rainwater flow into site drains to stop it from overflowing. Meanwhile, forestry utilises bunds to avert or lower rainwater to stop irrigation or soil erosion.

Secondary Containment Bunds

The main and sole purpose of secondary containment bunds is to offer precisely what its name suggests. It serves as a secondary containment for the main containment of liquids stored. These are developed specially to stop the leakage of dangerous liquids to the external environment in case the main containment vessel fails.

Drip Trays

A drip tray is a drainage basin for minor spills and drips. The purpose of drip trays is to permit upkeep of tools where there is a chance of remaining liquids inside the pipework and tools after drainage and isolation. They are not made to keep massive amounts of liquids.

In today’s industry, there are several samples where the wrong kind of spill control is utilised. There are also situations wherein the right kind is misdesigned. Because of this, improperly designed and constructed businesses are utilised as samples for future businesses.
