(a) All existing, proposed, or remodeled food service facilities discharging to the Parkersburg Utility Board’s POTW shall be required to install, at the owner’s expense, an approved and properly maintained FOG interceptor system.
(b) Sanitary sewer flows from toilets, urinals, lavatories, etc. shall not be discharged into the FOG interceptor system. These flows shall be conveyed separately to the sanitary sewer lateral and shall not be connected prior to the FOG interceptor.
(c) Solid food waste products, unused portions or scraps, are not intended for treatment by the POTW and should be disposed of through standard solid waste/garbage disposal means to a landfill by means of a trash hauler.
(d) Garbage Grinders shall not discharge to a FOG interceptor. Solids collect in the bottom of the interceptor and decrease capacity and contribute to maintenance issues.
(e) Produce preparation sinks shall not discharge into the FOG interceptor system.
(f) Commercial dishwashers are not recommended to be connected to the grease trap. Dishwasher discharge can melt grease and allow it to pass through an undersized grease trap. If the dishwasher must be connected to the FOG interceptor, the interceptor must be sized accordingly to allow sufficient detention time for the water to cool and the grease to separate before discharging to the POTW.
(g) Preflush or prescraping sinks that serve commercial dishwashing machines must be connected to a FOG interceptor provided that no grinder is used in these sinks.
(h) Yellow Grease shall not be discharged to a grease interceptor or the sanitary sewer collection system. This material is not intended for treatment by the POTW and disposal or recycling of this material should be arranged by the food service establishment.
