Grease Traps

Grease traps are designed to separate out the fats, oils, grease, and solids from the wastewater discharged into the sanitary sewer system. Kennedale requires restaurants, food processing facilities, automotive repair facilities, car washes, commercial laundries and all other facilities that the city deems necessary to install and maintain grease or grit traps. It is the responsibility of the generators to ensure that their grease/grit traps and the wastewater discharged from them are in compliance with all city requirements.

Grease Trap Maintenance & Service Required

In order to function properly fats, oils, grease and solids must be cleaned from a grease trap on a regular basis. Grease traps shall be one hundred percent (100%) pumped out at least once every ninety (90) days, and at all other times as necessary to maintain their effectiveness. The city may order a business to have its grease traps pumped out more frequently if the city determines it is necessary for the protection of the wastewater system.

Failure to properly clean and maintain a grease trap may subject the violators to penalties of up to $2,000 per violation per day.

A list of permitted transporters that are allowed to operate in the City of Kennedale can be found online here. 

Grease generators are required to use only permitted transporters for the cleaning and transporting of liquid wastes (including grease wastes). Failure to use a permitted transporter is a violation that may subject the generator to penalties of up to $2,000 per violation per day.

Grease Trap Sizing & Requirements

• Interceptors designed to remove oil and grease shall be designed to hold one hundred (100) percent of the discharger's estimated waste stream for a minimum of twelve (12) minutes.
• The interceptor shall have a minimum of two (2) compartments and a minimum of two (2) baffles.
• The interceptor shall be capable of separation and retention of grease and storage of settled solids.
• The interceptor shall be designed, constructed, and installed for adequate load-bearing capacity.
• A manhole cover shall be installed over each compartment of sufficient size to accommodate cleaning and maintenance.
• The interceptor shall be installed in a location outside of the building.
• The interceptor size shall be based on the following calculation or as determined by the authority:
• Total fixture waste stream ¹ × forty (40) percent × twelve (12) minutes = interceptor capacity.
• ¹ The total fixture estimated waste stream is determined by adding the diameters (in inches) of all drains discharging into the interceptor and multiplying this number by 7.5, in gallons.
• Dischargers who discharge extraordinary amounts of abnormal waste may be required to have a higher-than-minimum capacity interceptor.
• Locate the interceptor in a manner that provides ready and easy accessibility for monitoring, cleaning, and inspection.
