(a) Construction of Interceptors. Grease interceptors shall be constructed in accordance with PDI standards and shall be in accordance with Sections 1003.3.1 through 1003.3.4.2 of the Ohio Plumbing Code.
(b) Access. Access to grease traps and grease interceptors shall be available at all times, to allow for their maintenance and inspection
(c) Load-Bearing Capacity. In areas where additional weight loads may exist, the grease interceptor shall be designed to have adequate load-bearing capacity (example: vehicular traffic in parking or driving areas).
(d) Inlet and Outlet Piping. Wastewater discharging to a grease trap or grease interceptor shall enter only through the inlet pipe of the interceptor. Each grease interceptor shall have only one inlet and one outlet pipe.
(e) Interceptor Sizing. The required size of a grease interceptor shall be approximated by using the CHD/UPW Grease Interceptor Sizing formula shown in Appendix A. Most grease interceptors will have a capacity of not less than 1,000 gallons nor exceed a capacity of 3,000 gallons. If the calculated capacity using the CHD/UPW Grease Interceptor sizing formula exceeds 3,000 gallons, multiple units in series shall be installed.
See Appendix A for example of formula. Grease interceptor design represents minimum standards for normal usage. Installations with heavier usage require more stringent measures for which the user is responsible and shall pay the costs to provide additional measures if required by CHD/UPW. CHD/UPW reserves the right to evaluate interceptor sizing on an individual basis for facilities with special conditions, such as highly variable flows, high levels of grease discharge, or other unusual situations that are not adequately addressed by the formula.
