Sara, Dave, and Kevin began work on the sed tank design. We used existing files and tried to think up how the sed tank would function schematically. We concluded that the tank will require a plant leveling tank to set the water level in the sed tank and to divert the desired amount of water to the sed tank.

Sara, Dave, and Kevin continued work on the design of the sed tank. We wrote most of the programs necessary to solve for unknowns, and drew up a 2-D sketch of the plant. We also wrote and posted our midterm report of what we have accomplished on the pilot plant and the sed tank design.
