Identify the Method used for the dewatering of the foundation trenches

1.	Identify the Method used for the dewatering of the foundation trenches.(a) Pumping(b) Providing sumps and side drains(c) Well Point System(d) Cement groutingI got this question in unit test.This interesting question is from Deep Excavations in division Deep Excavations, Pile Foundations and Caisson of Construction & Building Materials
Answer» RIGHT answer is (b) Providing sumps and side drains For explanation I would say: In providing sumps and side drains, the side drains are constructed ALONG the bottom of the foundation Trenches. The sumps are constructed at a distance of 45 M to 60 M and the side drains are given such as SLOPE that water is collected in the sumps.
