The sump method involves pumping water from a sump located at the bottom of the excavation, while the well-point method involves installing a series of well points around the perimeter of the excavation and pumping water from those points. Both methods are effective for dewatering an excavation and are complementary to each other. Therefore, the best choice is E, which includes both the sump and well-point methods. The pit method is not mentioned in the text and is not a common method for dewatering an excavation.
