Answer: D - All of the criteria listed are used to design a dewatering system used in a trench during large diameter sewer line construction. The type of soil will often dictate the required pump capacity and overall cost of a dewatering system. For example, fine-grained soils require a higher capacity pumping systems than coarse-grained soils. Weather also plays a role - additional capacity is required for dewatering systems used in locales with constant precipitation.
