Appendix 3. Worksheet for sludge volume and treatment volume
O.R. Blizzard 1
Revised August 2008 6/19118
The average thickness of the sludge layer and the thickness of the existing liquid (sludge -free) treatment zone are determined
from the information on the Lagoon Sludge Surrey Form ( Items O and P, respectively). In this example, the average sludge
layer thickness is 2.5 feet and the existing liquid treatment zone is 3.6 feet. If the lagoon has a designed sludge storage volume,
see notes at end of the worksheet. The dimensions of the lagoon as measured and the side slope are needed
for calculations of sludge volume and of total treatment volume. If the lagoon is a standard geometric shape, the sludge
volume and the treatment volume in the lagoon can be estimated by using standard equations. For approximate volumes
of rectangular lagoons with constant side slope, calculate length and width at the midpoint of the layer, and multiply by layer
thickness to calculate layer volume, as shown in the example. For irregular shapes, convert the total surface area to a square
or rectangular shape. For exact volumes for lagoons with constant side slope, the "Prismoidal Equations" may be used.

2. Depth of the lagoon from top of bank to bottom soil surface (D)
3. Slope = Horizontal/ vertical side slope (S)

If the ratio R exceeds 0.50; than a sludge Plan of Action may be required. Check with DWQ for Information
on filing the Plan of Action.
Note: If the lagoon has a designed sludge storage volume (DSSV), subtract that volume from both the volume
of sludge (Vs) (Item 8) and from the volume of total treatment zone (Vz) (Item 14), and take the ratio.
Then, R = (Vs-DSSV) / (Vz - DSSV)
Example: If DSSV = 85,000 fe, then R = (169,860 - 85,000) / (447,174 - 85,000) = 84,860 / 362,174 = 0.24.

The average thickness of the sludge layer and the thickness of the existing liquid (sludge -free) treatment zone are determined
from the information on the Lagoon Sludge Survey Form ( Items O and P, respectively). In this example, the average sludge
