Grease Control Devices


Grease (control) is the word!

Grease haulers are in business to pump out the contents of grease control devices at food service establishments. They transport the fats, oils and grease (FOG) and settled solids for recycling or disposal at locations that accept such wastes, such as designated Hampton Roads Sanitation District (HRSD) treatment plants.

  • There are three types of grease control devices typically used at food service establishments. One is the Grease Trap, which is typically small and located indoors under the sink. These are designed for separating and retaining the FOG and settled solids while allowing water to continue to flow into the sanitary sewer. The Grease Interceptor is usually larger and located outside underground. Like the Grease Trap, interceptors are designed to separate and retain FOG and solids while allowing the remaining wastewater to be discharged to the sanitary sewer. The Grease Removal Device is an active, automatic device that separates and removes FOG from the waste stream and cleans itself of FOG periodically by electromechanical means.
  • Keep records on-site of grease control equipment pumping/cleaning and maintenance to provide to inspectors.
  • Install proper grease control equipment.
  • Maintain (routinely clean or pump out) grease control equipment. Check the interceptor regularly to make sure it is less than 25% full of grease and settled solids, contains outlet Ts, and the structure is in good operating condition.
  • Food service establishments should follow proper grease-handling protocols.
