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 determined from 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 3.5
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
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.
Example Your lagoon
1. Average Sludge Layer Thickness (T) 2.5 ft. L

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:
R = (Vs — DSSV) / (Vz — DSSV)
Example: If DSSV = 85,000 ft3, then R = (169,860 — 85,000) / (444,174 — 85,000)
R = 84,860 / 359,174 = 0.24

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 determined from 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 3.5
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
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.

If the ratio 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:
R = (Vs —DSSV) / (Vz —DSSV)
Example: If DSSV = 85,000 ft3, then R = (169,860 — 85,000) / (444,174 — 85,000)
R = 84,860 / 359,174 = 0.24
