What is the purpose of having a sump in the wash area?

• A. To catch contaminated water
• B. To hold fresh water
• C. To store pesticides
• D. To dispose of waste down the drain

Answer: (B)

The wash area sump is there to provide a reservoir of water specifically for cleaning equipment and PPE. Having a dedicated place to hold wash water keeps the process efficient—so you have a ready supply to rinse and scrub without constantly fetching more water—and it contains the water so spills and runoff don’t spread. This containment also means you can manage disposal of the used wash water properly later, rather than letting dirty water drain away uncontrolled. The other options describe outcomes that can happen with wash water, but they don’t capture the primary purpose of having a dedicated sump: to hold the water used for cleaning.
