Define Bell Trap
“A trap that has a vertical pipe conveying water from the trap covered by an inverted bowl so that the water flowing through the trap is required to pass under the submerged rim of a bowl and over the end of the pipe.”
The name comes from its bell looking shape.

Solution:
The Bell Trap offers these means in a cost effective way
