Abstract
A sump for the deposit and removal of particulate material mixed with a fluid, comprises a first and second reservoir formed in the surface of the earth. The first and second reservoirs each have a top at the surface of the earth and extend from the surface to a predetermined depth in the earth to form a bottom. The reservoirs have a common wall portion between them from the surface of the earth to a location intermediate the surface and the predetermined depth where the common wall terminates forming an opening between the first and second reservoirs. Particulate material is deposited in one of the reservoirs so that said material is free to fill the reservoir and move through the opening to the second reservoir. Pumping apparatus is mounted in the remaining reservoir at a depth between the terminus of the common wall and the bottom.
