I got this question in quiz.

I would like to ask this question from Deep Excavations in section Deep Excavations, Pile Foundations and Caisson of Construction & Building Materials

Answer 1

The correct option is (a) Deep well pumps

To explain: In case of multistage system of well points, the deep well pumps should be used when the instability of the side slopes is expected. As deep well pumps are expensive, they are adopted on important works.
