Sump conditions occur when water collects at a low point and does what?

• A. A dry basin with no water
• B. Water collects at a low point and captures runoff
• C. A vertical drain without any barrier
• D. A barrier that leaks

Answer: (B)

Sump conditions are about water pooling in a low point and capturing runoff. When water collects there, it creates a small basin where flow is slowed, giving sediments a chance to settle before the water is released or redirected. That’s why the description of a sump as water collecting at a low point and capturing runoff is the best fit. The other scenarios don’t describe a low-point pool that gathers runoff: a dry basin has no water, a vertical drain without a barrier is removal rather than collection, and a leaking barrier indicates uncontrolled escape rather than a sump.
