The total volume of the walls of the flocculation tank depends on the length of the flocculation tank, the thickness of the plant wall, the height of the flocculation tank, the number of flocculation channels, and the width of the flocculation channels. Since all of the walls in the flocculation tank are the same thickness, the volume can be easily calculated by multiplying the area of the floc walls by the thickness of the plant wall (T.PlantWall).

The area of the floor of the flocculation tank depends on the length of the flocculation tank, the thickness of the plant wall, the number of flocculation channels, and the width of the flocculation channels. The volume of the floor of the flocculation tank is simply the product of the area and thickness of the floor:

The volume of the floc baffles is dependent on the width of the channels, the thickness of the baffle, the length of the baffle, and the number of baffles per channel. The number of baffles per channel is a calculated variable based on the length of the flocculation tank and the perpendicular spacing between baffles, which differs per channel. The baffles are also split between upper and lower baffles. Since the floc channel begins with a lower baffle, the equation is set-up so an odd number of baffles results in an extra lower baffle. If there are an X number of floc channels in a floc tank, the N.FlocChannelBaffles, L.FlocBaffleUpper, and L.FlocBaffleLower are X value arrays, which allow us to use a simple dot product to find the total length of the tank's baffles, rather than calculating each channel individually.

The area of the floor of the sedimentation tank depends on the length and width of the sedimentation tanks as well as the number of sedimentation tanks. The volume of the floor of the sedimentation tank is simply the product of the area and thickness of the floor. There has been some question as to whether the thickness of the inner walls of the sedimentation tank (T.PltWall) and that of the outer walls (T.PlantWall) is the same. Assuming they are not the same, the equations for the area and volume of the floor of the sedimentation tank are as follows:

The only other variable that needs be specified by the user to determine the other dimensions of the stock tank is diameter of the stock tank. Once the diameter has been set, the radius is simply half the diameter, and the corresponding required height can subsequently be calculated.
