When it works, it’s like you don’t even know the whole system is there. The water comes in, the sediment settles to the bottom of the catch basin, the water then reaches a certain volume where it hits the pipe, and then it begins to drain into the pipe which connects to the main storm sewer line and then off to the main outlet. When functioning correctly, the catch basin is a remarkably elegant and time tested solution to stormwater runoff. The pipe connecting the catch basin to the storm sewer system is typically about halfway up in the Catch Basin.
