1001.1.4 Grease Trap And Interceptor Sizing Formulas - Bixby added. This provision has been added by the city of Bixby to provide higher standards and requirements than established by the Oklahoma uniform building code commission by specifying formulas for determining how grease traps and interceptors shall be sized. This section has been added to read:
"It is the responsibility of the generator and the generator's engineer to ensure that the wastewater discharged from their facility complies with the city's discharge limitations. For the purpose of plans review, a general assessment of grease trap and interceptor design and size shall be performed using the formulas provided in this section. (These formulas have been demonstrated as industry standards capable of achieving the city's discharge criteria when systems are maintained in proper condition. However a licensed engineer may use an alternate method and submit the calculations with the trap or interceptor information for review.)
Method One:
M x W x R x S = Required Size (liquid capacity)
 
Where:
M
=
Number of meals per peak hour. Number of meals served at peak operation hour (seating capacity) x peak factor. The peak factor for fast food restaurants shall be 1.33. The peak factor for all other food service types shall be 1.00.
W
=
Waste flow rate. The waste flow rate with a dishwasher shall be a six (6) gallon flow and the waste flow rate without a dishwasher shall be a five (5) gallon flow. The waste flow rate for a single service kitchen shall be a two (2) gallon flow and the waste flow rate for a food waste disposer shall be a one (1) gallon flow.
R
=
Retention time. Retention times for commercial kitchen waste and dishwashers shall be two and one-half (2.5) hours. The retention time for a single service kitchen shall be one and one-half (1.5) hours.
S
=
The storage factor. For fully equipped commercial kitchens having an eight (8) hour operation, the storage factor shall be one (1), for sixteen (16) hour operations the storage factor shall be two (2), for twenty-four (24) hour operations, the storage factor shall be three (3). For single service kitchens, the storage factor shall be one and one-half (1.5).
 
Method Two: (Five (5) Hour Detention/Peak Flow)
G x A x P x D = Required Volume Of Trap
 
G
=
Gallons of water used per hour of operation.
A
=
Average "gray water" flow per hour. The average "gray water" flow per hour shall be 0.75.
P
=
Peak flow factor. The peak flow factor shall be 1.9.
D
=
Hours of detention. The hours of detention shall be 5.
 
Method Three: (Alternate Sizing Formulas-Proposals)
Food service establishments that propose the use of alternate sizing techniques or procedures that result in specifications that differ from calculated requirements (or are less than the required minimum of 750 gallons), shall submit formulas and other basis to support the proposed grease trap size and installation. Submissions must provide documentation supporting the proposal's ability to meet effluent quality requirements. Proposals must be signed by a licensed plumbing contractor or professional engineer. Under no circumstances shall a grease trap smaller than 500 gallons be accepted."
