Complies to IAPMO UPC
Gravity Grease Interceptor (GGI) sizing and construction is consistent with industry protocol for
complying with the sewer pre-treatment regulations. GGI sizing is based on 30-minute retention time.
Consult Highland Tank for alternate sizing methods. Inlet diameter/flow must not exceed that of the
outlet. Improper pumping of wastewater into the PGI can result in increased turbulence and less
efficient separation; consult Highland Tank for influent pumping system selection.
Interior Lining
Custom designs are available to
meet AHJ requirements.
