Re: Grease and Sand/Oil Interceptor Observation Procedure
Welcome to South Arapahoe Sanitation District!
Kennedy/Jenks Consultants is the consulting engineer for South Arapahoe Sanitation District (SASD). We coordinate the maintenance program related to the District’s main sewer lines, which includes observing grease and sand/oil interceptors and main sewer lines within commercial facilities in the District.
Owners of restaurants and other businesses that are considered significant generators of fats, oil, and grease (FOG), are required to have and maintain an external grease interceptor (SASD Rules and Regulations 9A-3-2). As you may know, these interceptors help prevent excessive amounts of grease from entering the wastewater collection system. If unimpeded, grease could ultimately cause blockages and sewer backups.
Similarly, owners of businesses that discharge any sand (or other inert debris) and/or petroleum bydrocarbons and other related undesirable matter into the sanitary sewer service are required to have and maintain an external sand/oil interceptor (SASD Rules and Regulations 9A-3-2). As you may know, these interceptors help prevent excessive amounts of sand and/or oil from entering the wastewater collection system. If unimpeded, the sand and/or oil could ultimately cause blockages and sewer backups.
Owner Responsibility: Businesses/Owners are responsible for pumping their grease and/or oil interceptors on a regular schedule ensuring their interceptors are maintained and in good, working order. All users connected to interceptors will be required to pump their interceptors quarterly, or every three (3) months, at a minimum. Cleaning intervals must be adjusted so as not to allow the interceptor to be more than twenty-five percent (25%) full of solids and grease at any time. For your reference, a list of pumping contractors is provided in the following pages.
Observations by SASD: The District’s engineering consultant, Kennedy/Jenks Consultants, performs regular observations of interceptors. Kennedy/Jenks Consultants’ personnel may go upon the property where any interceptor is installed to view the interceptor as it deems necessary. New facilities are observed quarterly for the first year. After the first year, observations are performed a minimum of every 6 months. If the facility has a history of non-compliance with SASD requirements, more frequent observations may be performed at the expense of the owner.
Kennedy/Jenks Consultants’ personnel may request to review the most recent receipts from the removal and hauling of the materials collected in the grease interceptor. Businesses/Owners are required to keep records of all maintenance activities for a minimum of one (1) year.
Failure to comply with SASD regulations: Facilities that are required to pump and/or repair interceptors shall be given written notices of violation. Pumping and repairs shall be completed within a maximum of five (5) calendar days and fifteen (15) calendar days, respectively, upon written notice of violation. Facilities with violations shall be re-visited following the elapsed time period to ensure compliance.
The best way to avoid excess grease in the sewer system is to follow Best Management Practices (BMP) for Fats, Oil and Grease (FOG) Control. A copy of the BMP recommendations is attached for your information.

GREASE AND SAND/OIL INTERCEPTOR OBSERVATION PROGRAM CHARGES
Per the rules and regulations of the Littleton/Englewood Wastewater Treatment Plant, all facilities which are significant generators of grease or sand/oil are required to have an external grease interceptor, an internal grease trap or sand/oil interceptor. Under the same rules and regulations SASD is required to regularly observe facilities in its program.
Below is a brief description of the charges for the SASD Grease and Sand/Oil Interceptor Observation Program:
Annual Fee: Beginning January 1, 2008 SASD will begin charging a $150 annual fee (subject to change at any time) to all facilities in its grease and sand/oil program. These include all restaurants, churches, schools, daycares and other establishments that serve food, regardless of whether the facility has an internal grease trap or an external grease interceptor, or if no trap or interceptor is present. It also includes all auto shops, car washes and other sand/oil generating facilities regardless of whether a sand/oil interceptor is present. This fee will help to cover the cost for regularly scheduled inspections.
Non-Compliance Charges: Beginning July 1, 2007 SASD will begin charging those facilities who fail semi-annual and/or quarterly inspections. Each facility will be given warnings for two consecutive inspection failures. Upon the third consecutive inspection failure during the year, the facility will incur a $500 penalty. For every consecutive failure thereafter, an additional $500 penalty will be incurred by the facility.
For more information regarding operation, maintenance and observation of grease or sand/oil interceptors please call Kennedy/Jenks Consultants at 303-985-3636.
Best Management Practices For Fats, Oil and Grease (FOG) Control
Fats, Oils and Grease (FOG) are food by-products that can severely damage a facility’s drain line system as well as the sanitary sewer system. FOG collect and eventually harden on the inside of the sewer pipes; preventing water from flowing and causing blockages.
Blockages in the sewer cause Sanitary Sewer Overflows (SSOs), dumping raw sewage into streets, lakes, streams, homes and businesses.
The best way to prevent blockages is to keep FOG out of the drain line system. Below is a list of Best Management Practices that will help to prolong the life of your drain line system and reduce the inconvenience and cost of line blockages.
FOLLOW THE DO’S AND DON’TS OF BEST MANAGEMENT PRACTICES
Don’t
- Don’t put grease or fryer oil down any sink or floor drain.
- Don’t dispose of food or food scraps in sinks.
- Don’t pour bleach directly down ANY drain. Bleach when used improperly dewaters grease, making is as hard as concrete.
- Don’t take out sink strainers or drain covers. Empty scraps into trash, not down the drain.
- Don’t use cleaning chemicals improperly. Follow the instructions on the label, for your safety as well as the safety of the environment.
Do
- Do throw all solids including waste food into the garbage.
- Do encourage staff to be conservative about use of FOG in food preparation and serving.
- Do use ALL cleaning chemicals according to the instructions on the label.
- Do use paper towels to soak up oil and grease under fryer baskets and to wipe down work areas. Dispose of the paper towels into the trash.
- Do run a LOT of water if you must use the garbage disposal.
- Do check all sinks and floor drains for strainers and covers.
- Do know the location and operation of all FOG control devices.
- Do deposit used fryer oil in the appropriate container.
- Do keep dumpster areas clean and free of loose trash.
