Maintaining your grease trap
Grease interceptors or grease traps as they are commonly called, prevent certain materials from
discharging to the sanitary sewer. When grease and solids enter the sanitary sewer, they can
cause blockages which can result in sanitary sewer overflows (SSO’s). Often, SSO’s reach
storm drains and flow to creeks, streams and rivers. The law prohibits SSO’s and it is the city’s
responsibility to prevent blockages from occurring.
Food establishments that offer high fat menu items which include meat and dairy products, soups
and stews, gravies and sauces, bakery items and salad (raw and prepared) are required to have
grease interceptors. On August 14, 2007, new regulations regarding the frequency of service for
grease interceptors was approved by the city council.
Grease interceptor service requirements for establishments that prepare or manufacture food
products are as follows:
- Food manufacturers – monthly
- Establishments that offer fried food products – monthly
- Fast food restauraunts - monthly/quarterly (determined by meals served)
- Full service restauraunts – quarterly
- Childcare facilities – biannually
The maintenance frequency is also shown on the health permit that is issued to each food service
Each facility must follow the City of Grand Prairie’s service guidelines in disposing of their
grease trap waste.
- Only use a liquid waste hauler that holds a valid permit with the city. Please
request to see their permit.
- The food establishment manager or owner must sign the manifest from the transporter.
- The gold copy (transport receipt) should be given to the food service manager or owner
immediately after the grease trap is serviced.
- The pink copy (disposal receipt) should be returned to you from the transporter within 15
days of the maintenance of your grease trap.
(THE FOOD SERVICE ESTABLISHMENT SHOULD HAVE BOTH COPIES OF
THE RECEIPTS ON FILE AT THE ESTABLISHMENT)
- The food establishment manager or owner must keep both copies for at least two years
and must be available for inspection at all times.
Environmental Services Department staff will strictly enforce this ordinance. Failure to maintain
grease interceptors and/or maintain records may result in either judicial proceedings and/or the
facility may be required to install an industrial waste sample point and pay monitoring fees.
