What is a spill catchment basin used for?

A spill catchment basin is primarily designed to contain and manage liquids that could potentially spill from equipment, storage tanks, or other sources. It serves a crucial role in preventing environmental contamination by capturing spills before they can spread or seep into the ground or nearby water sources.

This basin can also serve a secondary purpose of storing leftover oil-absorbent materials that might be used during spill cleanup efforts, thereby assisting in the overall spill management process. By providing a dedicated area for collection and containment, the spill catchment basin aids in both immediate response to spills and long-term management of spill response materials.

Thus, the correct choice encompasses both the function of the basin in spill containment as well as the management of materials necessary for cleaning spills, which is why it is appropriate to select both functionalities together.
