tcalculations of sludge volume and of total treatment volume. If the lagoon is a standard geometric shape, the sludge
lone and the treatment volume in the lagoon can be esthriated by using standard equations. For approximate volumes
rectangular lagoons with constant side slope, calculate length and width at the midpoint Of the layer, and multiply by layer
ckness to calculate layer volume, as shown:in the example. For irregular shapes, convert the total surface area to a square
rectangular shape. For exact volumes for lagoons %vith constant side slope, the 'Prismoldal Equations' may be used.

Appendix 3. Worksheet for sludge volume and treatment volume Revised August 2008
The average thickness of the sludge layer and the thickness of the existing liquid (sludge -free) treatment zone are detennined
from the information on the Lagoon Sludge Survey Form ( Items 0 and P, respectively). In this example, the average sludge
layer thickness is 2.5 feet and the existing liquid treatment zone is 3.5feet. 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 sludgovolume 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 toyer, and multiply by layer
thickness to calculate layer IfOk1103, 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.

Note: If the lagoon has a designed sludge storage volume (DSSV), sail:mot that volurne 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)
