C. Variance from grease interceptor requirements. Grease interceptors
required under this section shall be installed unless the DuBois Wastewater

approved by the City of DuBois and shall have a minimum of two compartments
with fittings designed for grease retention.
B. All interceptors shall be of such capacity and volume as to retain
the liquid for a sufficient length of time to permit the separation
of FOG from the other wastes before they are discharged into the building
drain or sewer. Minimum hydraulic retention time shall be calculated
using the Grease Interceptor Sizing Worksheet of the Uniform Plumbing
Code. If necessary, strainers shall be installed to retain and collect
solid materials one-half inch or larger in any dimension.
