wastewater in a grease interceptor is so
acidic that it meets EPA2 requirements for
neutralization (pH<5). Acidic waste is extremely

How does a smaller interceptor outperform a larger interceptor?
Flow patt ern. Gravity grease interceptors are assumed to work according to Stokes Law4
when sized for a minimum of 30 minutes retention time. However, WERF’s 2008 report1
concluded that retention time alone was insuffi cient to assure proper separation. The report
also identifi ed uncontrolled inlet velocity and turbulence as the primary cause of short
circuiting, leading to bypass in traditional gravity designs.
141-913-951-3300 | www.schierproducts.com | Made in the USA | Catalog 2014
NOTE: the above graphics depict the certifi ed capacities of select Great Basin™ models vs. typical gravity interceptors, and should not be used for sizing cross
reference. See pages 17-18 for sizing recommendations. Grease capacities for gravity units shown above based on 25% rule with 50/50 FOG to solids ratio.
Gravity interceptors are considered full when 25% of their
wet volume consists of FOG, solids or both. A typical core
sample from a gravity interceptor will show less FOG than
solids because of periodic short circuiting1.
A core sample of a Great Basin™ hydromechanical
interceptor has a deeper FOG layer than a gravity
interceptor because the design is more effi cient and does
not suff er from short circuiting.
It is common for a Great Basin™ interceptor to have a
combined FOG / solids layer well over 50% of its wet volume
while still maintaining greater than 90% effi ciency (see
Summary of Great Basin™ Performance table on page 16).

GREAT BASIN™ PRODUCT SELECTIONGrease Interceptor Sizing Guidelines
Schier recommends two steps for grease interceptor sizing: fi rst by fl ow rate per plumbing code requirements, then by grease capacity for pump-out cycle. Review plumbing code and locally adopted ordinances for specifi c requirements (see pages 21-22).
Step 1 of 2: size by fl ow rate
Drainage system fl ow rate (GPM) should be determined by the size of the interceptor’s inlet pipe. Schier
recommends calculating fl ow rate based on half-pipe fl ows (2 - minute drainage period) as per standard
practice for engineered plumbing systems.
Did You Know?
WERF’s 2008 report1 included comprehensive testing of fl ow rates in the grease waste lines at several
diff erent food service establishments. The study indicates that fi xtures are used very intermitt ently and
signifi cantly less than calculations for full or half pipe fl ows. Sizing for fl ow rate, while important, should
not be the sole method for grease interceptor selection.
The following table provides an extrapolated summary:

Step 2 of 2: calculate grease capacity
After sizing for fl ow rate, calculate the grease capacity needed per the formula below. Recommended interceptor
should have adequate grease storage capacity to support desired pump-out frequency.

NOTE: plumbing code map and digests may not be applicable in some situations. Review plumbing codes and any locally adopted ordinances for specifi c requirements regarding sizing, installation and maintenance of grease interceptors.
IPC (2012)6 – Hydromechanical Grease Interceptors shall be tested and sized in accordance to ASME A112.14.3, CSA B481.1 or PDI G101. Gravity Grease Interceptors (generally 300 gallons in size or larger) are exempt from those requirements. Dishwashers (without prerinse sinks) must connect to a grease interceptor. Food waste grinders that discharge to a grease interceptor must fi rst be routed through a solids interceptor.
UPC (2012)7 – Hydromechanical Grease Interceptors (HGI) shall be tested and rated in accordance to ASME A112.14.3, CSA B481.1 or PDI G101. HGI sizing shall be according to Table 1014.2.1 by fi xture volume or by pipe diameter. HGI installation is permitt ed outdoors or indoors. Gravity Grease Interceptors (GGI) shall comply with IAPMO/ANSI Z1001 and shall be sized by Drainage Fixture Units to determine the liquid gallon holding capacity (minimum 500 gallons). Food waste grinders and dishwashers shall not be connected to or discharge to any grease interceptor unless specifi cally required or permitt ed by the Authority Having Jurisdiction.
NPCC (2010)8 – Every interceptor shall have suffi cient capacity to perform the service for which it is provided. Any equipment discharging waste with organic solids shall not be located upstream of a grease interceptor unless it is fi rst routed through a solids interceptor. Although it is not listed in the plumbing code, most jurisdictions in Canada now require compliance with CSA B481.1.
NSPC (2012)9 – Hydromechanical Grease Interceptors (HGI) shall comply with ASME A112.14.3 or PDI G101. Sizing shall be in accordance to PDI G101, Table 6.2.10 or the manufacturer’s instruction. Where a food waste grinder discharges through an HGI it must be routed through a solids interceptor prior to the grease interceptor. Gravity Grease Interceptors (GGI) shall be sized and designed by a locally registered and licensed design professional. GGIs shall be sized by gallons factoring a 30-minute retention time at half pipe fl ows per Appendix K. Food waste grinders may discharge directly to a GGI. Dishwashers are permitt ed to be routed to HGIs or GGIs.
MODEL PLUMBING CODES
Illinois Plumbing Code (2005)10 – Grease interceptors shall be made from corrosion-resistant materials, shall have water-tight covers securely fastened in place and shall meet PDI-G101 or ASME A112.14.3. A grease interceptor located on the same fl oor as the fi xture shall have one-half the liquid holding capacity of the fi xture. A grease interceptor located on a fl oor below the fi xture shall have sixty percent of the liquid holding capacity of the fi xture. Where two or more sinks or receptacles are connected to an interceptor the liquid holding capacity shall be based on the combined volume of the fi xtures served.

Kentucky State Plumbing Law (2013)11 – Kentucky Administrative Regulations (Title 815 Public Protection Cabinet Department of Housing, Buildings and Construction Chapter 20 Plumbing, 110 Traps and Clean-outs, section 11 Grease Traps) mandates that grease traps be installed for a restaurant, food service establishment or other business establishment as required by municipal ordinance. Section 5 of the code titled Content of Approved Parts or Materials List (APML) provides a list of approved manufacturers of grease interceptors by name and model number and also lists any specifi c requirements regarding the installation of the approved interceptor. Models PATG-1820, PATG-2025, PATG-2635, PATG-3050, GB-15, GB-20, GB-25, GB-35, GB-50, GB-75 and GB-250 are approved for installation. Models GB-75 and GB-250 are approved with the installation of accessible, two-way cleanouts on the inlet and the outlet and shall not receive waste from food waste disposal units.
Louisiana Plumbing Code (2013)12 – Grease Interceptors (GI) are defi ned as having less than 125 gallons capacity, must comply with ASME A112.14.3 or PDI-G101 and must have a minimum fl ow rate of 20 GPM. Large Capacity Grease Interceptors (LCGI) are defi ned as having at least 125 gallons capacity and comply with ASME A112.14.3 or PDI-G101. Grease Traps (GT) are defi ned as having at least 125 gallons capacity and are generally installed outdoors. The code requires either a GT or LCGI for all instances of new construction or substantial renovation. GIs must be specially approved by the plumbing offi cial when permissible. GT and LCGI sizing is calculated in gallons and factors number of persons served during the largest 1-hour meal period and whether the unit is installed with or without a garbage grinder. Alternatively when number of persons is not available, sizing may also be calculated by factoring square footage of the dining area.

It has been shown that the most successful FOG abatement programs address all of the following topic areas:
kitchen fi xtures, interceptor standards and ratings, interceptor sizing, mandated design elements, FOG droplet size and
numeric limits, interceptor materials of construction and interceptor maintenance.
GREAT BASIN™ REGULATORY COMPLIANCE
Summary: the only way for a jurisdiction to ensure FSEs do
not bypass FOG to the collection system is to mandate that
all kitchen fi xtures be routed to a properly sized, installed and
maintained grease interceptor. However, jurisdictions should
weigh the risks and rewards of routing dishwashers and food
waste disposal units to a grease interceptor.
Kitchen Fixtures
Some plumbing codes have exacerbated FOG problems by using
vague language on which fi xtures should be routed through an
interceptor. Extensive fi eld inspections have proven that FOG is
being introduced through every fi xture in the kitchen at one point
or another.
There are two types of kitchen fi xtures that need
special consideration:
1. Dishwashers: dishwasher discharge is a high-temperature mixture
of FOG, solids, water and surfactants from excess detergent.
Testing has shown that higher temperatures actually assist in
separation performance16. However, interceptors are designed to
separate free fl oating FOG, not FOG that has been emulsifi ed by
surfactants. There are two schools of thought on this topic, those
who feel that plumbing the dishwasher to the interceptor is a net
positive for FOG capture and those who feel it is a net negative.
Schier did not fi nd any evidence to prove either school of thought
“more correct.”
2. Food waste disposal units: many food service establishments (FSEs)
scrape dirty dishes into their food waste disposal unit increasing
FOG-laden solids that can be discharged to the collection system.
This is a good reason to route these fi xtures to a grease interceptor.
However, extra solids loading from a food waste disposal unit can
be problematic. To help prevent the interceptor from prematurely
fi lling up with food waste, jurisdictions can require a solids
interceptor after a food waste disposal unit or consider eliminating
food waste disposal units altogether to improve interceptor
performance and reduce the amount of total suspended solids
(TSS) entering the collection system.
Interceptor Standards and Ratings
Plumbing codes recognize three standards that govern the
performance of hydromechanical grease interceptors (HGI)
across the United States and Canada: ASME A112.14.3, PDI-G101
and CSA B481.1. All three standards use the same testing and
rating procedure (see more info on page 16). Interceptors tested
and rated in accordance with one of these standards help assure
jurisdictions that they work effi ciently up to their rated capacity.
The primary standard governing gravity grease interceptors (GGI)
is IAPMO/ANSI Z1001, which outlines design and construction
elements, but does not require a performance test and off ers
no ratings.
Summary: for a more eff ective pretreatment program,
jurisdictions should focus on approving standards with
performance testing requirements and ratings that give
jurisdictions a higher degree of confi dence that these devices will
operate correctly in the fi eld, rather than design and construction
standards which provide no assurance of performance.
ASME A112.14.3 Test Apparatus. See page 16 for more information.
Summary: Schier’s Grease Production Sizing Method (see pages 17-18) provides a more accurate way to size grease interceptors that considers both the fl ow rate and the amount of grease likely to be produced. This allows for the selection of a grease interceptor that can handle the incoming fl ow rate while providing enough capacity to ensure that an FSE can aff ord to keep their interceptor properly maintained.
Interceptor Sizing
Current sizing guidelines found in plumbing codes, interceptor standards and pretreatment ordinances focus on sizing grease interceptors by fl ow rate, and sometimes by extension, retention time. The problem with this approach is that there is no correlation between fl ow rate and the amount of FOG present in the waste stream. FOG type and concentration is a function of menu type and the amount of food being produced. For example, a restaurant serving hamburgers and deep fried food will produce more greasy waste per meal than a sandwich shop. However, if both FSEs have similar kitchens and typical fl ow rate based sizing is applied, both facilities could end up with the same interceptor. This creates both a compliance and enforcement problem.

Mandated Design Elements
FOG Droplet Size and Numeric Limits
The above graphic depicts the rise rate of FOG by micron size (50 microns
and 150 microns) at a constant fl ow rate of 100 GPM, temperature of 150º F
and a specifi c gravity of 0.9. Microns shown not actual size.
Summary: it is not advisable to use numeric concentration
limits on grease interceptors as the determining factor
for compliance enforcement. Recognizing that certifi ed
interceptors will perform satisfactorily up to their rated
capacity, a more eff ective approach is to enforce proper and
regular interceptor maintenance.
Larger grease droplets separate more quickly than smaller
droplets. Grease interceptors are designed to operate based on
gravity diff erential separation of FOG droplets roughly 150 microns
in size or larger17. It is impractical to remove anything smaller
than 150 microns because the interceptor would have to be
exponentially larger to allow smaller droplet sizes to separate (see
left graphic).
However, because jurisdictions are required to set local limits
on unauthorized pollutant discharges, some aff ect numeric
concentration limits on FOG such as 100 PPM (mg/L). Compliance
is typically verifi ed by applying EPA test method 1664A18 to an
effl uent grab sample.
There are two problems with mandating numeric limits for FOG:
1. FOG droplets less than 150 microns in size are common in a
restaurant waste stream but are too small to be separated by
an interceptor. However, an effl uent grab sample containing a
signifi cant amount of emulsifi ed FOG smaller than 150 microns
may suggest non-compliance when in fact the interceptor is
operating correctly. This creates an enforcement problem for
the jurisdiction.
2. EPA test method 1664A18 is fl awed, yielding a high degree of
variability in test results. According to the 2008 WERF study1
“as an indirect outcome of this study, the FOG concentration
measurement results showed that the EPA test method
1664A18 displayed signifi cant variability when measuring
known concentrations of total oil and grease. Variability in the
measured concentration was approximately 40%, making it
impossible to confi rm or refute whether the grease interceptor
is properly achieving the required effl uent limit.”
When jurisdictions mandate
prescriptive design elements
for grease interceptors, such
as requiring baffl es or concrete
construction they limit FOG
abatement eff orts by stifl ing
both proven and emerging
technologies and third party
research such as the 2008
Water Environment Research
Foundation (WERF) report1.
Many grease interceptors today owe their designs to the criteria
developed at the Iowa Institute of Hydraulic Research (IIHR) in
the early 1940s. The key principles of design were controlled inlet
velocity and gravity diff erential separation according to Stokes Law
Summary: grease interceptor technologies have greatly
improved over the past 10 years, providing bett er effi ciencies
and more storage capacities than ever before. For this reason,
jurisdictions should avoid mandating prescriptive design
elements for interceptors which may prevent a jurisdiction from
taking advantage of improved designs.
(an equation which predicts the rise rate of a droplet of oil in static
water based on its size, temperature, specifi c gravity, velocity
and viscosity).
Early testing by the IIHR, published in their 1944 article Symposium
on Grease Removal, Design and Operation of Grease Interceptors4
indicates that infl uent velocity in the interceptor must be near
0.08 to 0.10 ft/sec to allow FOG to separate by gravity according
to Stokes Law. When interceptors included internal baffl es, it was
discovered that the infl uent velocity needed to be lower by half
(near 0.04 to 0.05 ft/sec) to compensate for turbulence created by
the baffl es.
Some jurisdictions prefer larger gravity grease interceptors (GGI)
accepting the common arguments that they are designed around
the principle of Stokes Law4 and that internal baffl es enhance
performance. The 2008 WERF report1 found two problems that
undermine these arguments: the inability of GGIs to control
infl uent velocity and regions of higher velocity zones created by the
inclusion of an internal baffl e wall. These problems combine in an
interceptor causing a turbulent fl ow path which leads to “short-
circuiting” (unexpected bypass). The 2008 WERF report1 has raised
serious questions about assumed effi ciencies and capacities of
these devices.

GREAT BASIN™ REGULATORY COMPLIANCEInterceptor Materials of Construction
As FOG breaks down in an interceptor, anaerobic bacteria convert naturally occurring sulfate molecules into sulfi des, which form hydrogen sulfi de gas (H
2S) in the free air space of the interceptor.
Airborne aerobic bacteria consume hydrogen sulfi de gas and convert it into sulfuric acid (H
2SO
4) in the wastewater of the
interceptor. Sulfuric acid oxidizes metal causing a reaction of iron with water to form iron oxide (rust). Similarly sulfuric acid reacts with calcium hydroxide (Ca(OH)
2) in concrete forming calcium
sulfate (CaSO4) that in the presence of water (H
2O) creates gypsum
(CaSO4·2H
2O). Both metal and concrete are guaranteed to fail over
time due to these processes.
A recent study submitt ed to the University of North Carolina19 concluded that FOG deposits in sewer piping systems are the result of free fatt y acids reacting with metals both in the headspace above the waste water and in the waste water area itself. The most common metals found in tested FOG deposits were calcium and iron from hard water and concrete and steel corrosion.
Summary: grease interceptors should be constructed of
non-corrosive materials (i.e. polyethylene, fi berglass, etc.) that
will not react with hydrogen sulfi de gas or sulfuric acid. This
eliminates interceptor corrosion and may help reduce FOG
deposit creation.
SEWER BLOCKAGE FORMATION19
The start of a blocked pipe begins when grease and solids collect on the top and sides of the pipe interior.
The build-up increases over time when grease and other debris are washed down the drain.
Excessive accumulation will restrict the fl ow of wastewater and can result in a sanitary sewer overfl ow.
Interceptor Maintenance
Summary: ultimately it is up to the FSE to keep an interceptor
properly maintained; however there are a few things a
jurisdiction can do to help:
• Make sure the FSE knows how much grease their interceptor
can hold
• Use Schier’s grease production sizing tool to show an FSE
how much grease they are producing and therefore how
often they will need to maintain their interceptor
• Give the FSE Schier’s recommended kitchen BMPs (see page
26) which will help them mitigate the amount of grease and
solids they introduce to their interceptor
All grease interceptors have a maximum grease holding capacity,
whether tested and rated or not. When that capacity is exceeded an
interceptor will bypass grease to the collection system. It is critical
that grease interceptors be maintained as they become full and
not allowed to fi ll beyond that point. Many jurisdictions use the 25%
rule (when FOG and/or solids comprise 25% or more of the overall
tank volume), to determine when an interceptor is full and apply the
rule to both HGIs and GGIs. This rule is the industry’s conservative
estimate of capacities and assumes that FOG and solids loading
equally aff ect interceptor effi ciency. While that may be true for older
hydromechanical and gravity interceptor designs, it isn’t necessarily
true for newer technologies.
Advancements in grease interceptor designs have led and are
leading to more effi cient interceptors with substantially larger
storage capacities, rendering the 25% rule irrelevant for these
devices. To determine the FOG capacity of an interceptor as a
percentage, fi rst take the rated grease storage capacity in pounds
and divide that number by 7.3 (weight of the lard used in the test),
which converts the grease from pounds to gallons. Then, take the
grease capacity in gallons and divide that by the total wett ed volume
of the interceptor in gallons. For example, the Schier Products
GB-250 has a grease storage capacity of 1,076 lbs, dividing that by
Contractor cleaning above grade GB-35
7.3 converts it into 147.4
gallons. The interceptor
has a total wett ed
volume of 275 gallons.
Dividing 147.4 by 275
yields 54%, meaning
that the GB-250 has a
grease storage capacity
of 54% of its total wett ed
volume. Grease storage
capacity is independent
of solids storage
capacity, which in the
GB-250 is 105 gallons.

How overfl ows happen
In an installation with no air gaps, the weight of the water provides the head pressure needed to force the fl ow through the piping and standing
water in the interceptor. When indirect connections are introduced, there is no longer enough head pressure. For this reason, troubleshooting
steps may be required to restrict fl ow from the fi xtures and prevent overfl ow at the air gap.
Confi g. a & b above: sinks drain normally until the fl ow is thrott led by the size of the inlet pipe ( ), the fl ow control ( ), standing water in the
interceptor ( ) or a combination of all three. This causes water to “stack up” back toward the sink. During this stack up, water is still fl owing
through the interceptor. The unrestricted fl ow rate from the sinks exceeds the downstream restrictions, and may cause an overfl ow event at
the indirect connect discharge point(s)( ).
Troubleshooting procedure for eliminating indirect connection overfl ows
Three factors aff ect fl ow rate and need to be considered when installing a grease
interceptor with indirect connections: depth and number of sink bowls, size and
length of inlet piping, fl ow rate of interceptor. Consider these when using the
following troubleshooting procedure:
step 1. Remove fl ow control plate ( ) from inlet diff user. Remove cover from
unit to verify that the inlet/outlet diff users don’t become submerged. Cut off top
of inlet diff user (ensure upstream sewer gas trap exists prior to cutt ing).
step 2. Install a rubber fl ow restriction end cap at each indirect connect
discharge point ( ). Punch a fl ow control orifi ce into rubber fl ow restriction
cap until optimal orifi ce size (fl ow rate) is achieved. Do this until the maximum
“open” position without an overfl ow is determined. Leave caps in place if local
code allows, or replace caps with tailpieces of matching orifi ce size. If the
maximum “open” position results in the sink being rendered unusable due to
slow drainage, the interceptor must be increased in size and/or moved further
downstream from the indirection connection.

Did You Know?
Regardless of sink volume (gallons), it’s depth that determines peak fl ow rate. The average
commercial sink bowl will produce an unrestricted peak fl ow rate of 22.5 GPM when
provided with 2" tailpieces. The peak fl ow rate occurs for the fi rst few seconds after the
stopper is pulled, then fl ow rate decreases. However, it is not appropriate to add peak fl ow
rates of all kitchen fi xtures (including sink bowls) together to get a combined peak fl ow
rate, because the drainage piping thrott les fl ow. In WERF’s 2008 report1, they found that
the maximum fl ow rate to any grease interceptor was 45 GPM.

When to Use the Flow Control Plate
The fl ow control plate (red) serves to keep fl ow rates at or below the rated capacity of
the interceptor. In many installation scenarios, the fl ow to the unit will never exceed the
rated fl ow of the unit, and thus the fl ow plate should be removed. Removing the fl ow plate
in these scenarios will not aff ect the separation performance of the unit, but will prevent
clogs. Use the guidelines below to determine when the fl ow plate should be installed:
Install fl ow plate when:
• Unit is rated at 35 GPM or below (note: built-in fl ow control is provided pre-installed on
models GB-15 through GB-35 and uninstalled on models GB-50 through GB-250)
• Unit is installed 13 ft. or more below kitchen fi xtures (as in basement installations)

add this vent if unit is installed one or more fl oors below the fi xtures being served (i.e. basement installations, etc.)
Additional Venting for Floor-Below Installations
Background: grease interceptors are
designed to handle atmospheric pressure.
When plumbing fi xtures are drained quickly, air
is trapped and pressurized in the downstream
piping. If not properly vented, dangerous
pressurization of the interceptor can occur.

Expanding Grease Capacity
typical not typicalseries installations parallel installations
Background: series installations have been standard practice
for over 30 years in some cities.
How it works: when installed in series, only the primary tank
is responsible for calibrating the fl ow rate (ex: two GB-250 units
installed in series will fl ow up to 100 GPM). Initially the fi rst unit will
fi ll up with grease while passing some grease to subsequent unit(s).
As the grease layer in the fi rst unit grows, more grease will pass to
subsequent units. When it reaches maximum capacity, the fi rst unit
will pass all grease to subsequent unit(s).
Background: true fi eld fl ow rates are almost never over 100 GPM.
The vast majority of fl ow rates are under 50 GPM. Average fi eld
fl ow rates are under 3 GPM1. See chart on page 17 for more info.
How it works: when installed in parallel with the addition of a
Flow Splitt er™, the system may achieve the combined fl ow rate
of all interceptors (ex: two GB-250 units installed in parallel will
fl ow up to 200 GPM). The Flow Splitt er™ is designed to handle
a wide range of fl ows from as low as 1 GPM up to the total
combined fl ow rates of all interceptors.
Consult full installation instructions for fl ow
control requirements.
Due to fl ow rate based sizing methods used by some
jurisdictions, interceptor fl ow rates greater than 100 GPM may
sometimes be required. Discuss with your Schier representative
prior to design/installation.

maximize oil and sand separation. Petroleum based oils are typically lighter than water and will
quickly rise to the surface by gravity diff erential separation according to Stokes Law17.
Option 1: size by drainage area for service facilities
When allowed, use the following sizing chart where motor vehicles are serviced and/or stored. For parking-only areas, consider option 2.
Option 2: size by fl ow rate for parking only facilities
Consider drain / supply line fl ow rates when sizing for applications where motor vehicles are neither serviced nor stored (parking-only areas).

Option 3: size by fl ow rate for elevator pits
ASME A17.1-2007/CSA B44-07 is the Safety Code for Elevators and Escalators.
It intended to serve as the basis for the design construction, installation,
operation, testing, inspection, maintenance, alteration and repair of elevators,
dumbwaiters, escalators, moving walks and material lifts. Section 2.2 details the
requirements for pits for all elevators governed by the code. 2.2.2.3 mandates
that permanent provision be made to prevent accumulation of ground water
in the pit, while 2.2.2.4 requires the necessary fl oor drain or sump pump meet
the applicable plumbing code for the jurisdiction. 2.2.2.5 requires all elevators
with Firefi ghters’ Emergency Operation to have a drain or sump pump. A sump
pump or drain shall have the capacity to remove 3,000 gallons per hour
(50 gpm) per elevator.
IPC mandates the installation of an oil separator for hydraulic elevator pits,
unless there is an approved alarm system installed. The intent of the code is to
prevent an oil discharge to the sanitary drainage system. Some manufacturers
produce a specially fi tt ed sump pump with an oil sensor and alarm unit which
functions to shut off the pump if oil is detected in the pit. For elevators with
Firefi ghters’ Emergency Operation the pit must be kept clear of accumulated
water as required in ASME A17.1-2007/CSA B44-07 section 2.2.2.5. However, it
may be possible for a sump pump with an oil sensor to shut off during a fi re
allowing the pit to fi ll with sprinkler water undermining a fi refi ghting operation.
The installation of an oil interceptor downstream of a sump pump satisfi es
both the elevator and plumbing codes.
Sizing Guidelines Following an Elevator Sump
First, select an oil separator that meets the pump fl ow rate. Then, choose oil separator with rating that is equal to or greater than the worst
possible discharge of hydraulic fl uid.

NOTE: plumbing map and code digests may not be applicable in some situations. Review plumbing codes and any locally adopted ordinances for specifi c requirements regarding sizing, installation and maintenance of oil interceptors.
IPC (2012)6 – Oil separators are required at repair garages, car-washing facilities, at factories where oily and fl ammable liquid wastes are produced and in hydraulic elevator pits (unless there is an approved alarm system installed). Oil separators shall be listed and labeled or must meet the design and sizing requirements of sections 1003.4.2.1 and 1003.4.2.2. Sizing in the code applies to garages and service stations and uses the square footage of the area drained. Oil separators are not required in parking garages in which servicing, repairing or washing is not conducted, and in which gasoline is not dispensed. Areas of commercial garages utilized only for storage of automobiles are also not required to be drained through an oil separator.
UPC (2012)7 – Oil / fl ammable liquid interceptors are required for repair garages and gasoline stations with grease racks or grease pits and factories that have oily, fl ammable or both types of wastes as a result of manufacturing, storage, maintenance, repair or testing processes. The vapor compartment shall be independently vented to the outer air. There are two approved standards for oil interceptors, IAPMO PS-80 or ASTM D6104. Where an interceptor is provided with an overfl ow line, an approved waste oil tank having a minimum capacity of 550 gallons shall be installed. Oil interceptors shall be listed and labeled or must meet the design and sizing requirements of section 1017.2. Sizing in the code is either based on the number of vehicles serviced, stored or both. Where vehicles are serviced only, the sizing is based on the square footage of the facility.
NPCC (2010)8 – Where the discharge from a fi xture may contain oil or gasoline, an oil interceptor shall be installed. Every oil interceptor shall be provided with 2 vent pipes that connect to the interceptor at opposite ends, extend to outside air and terminate not less than 2 meters above ground and at elevations diff ering by at least 300 millimeters. The vent pipes are permitt ed to be one size smaller than the largest connected drainage pipe but not less than 1-1/4 inches in size, or can be sized in accordance with the manufacturer’s recommendations. Every vent pipe that serves an oil or grease interceptor and is located outside a building shall be not less than 3 inches in size in areas where it may be subject to frost closure. There are no standards listed in the code governing oil interceptors.
NSPC (2012)9 – Liquid waste containing grease, oil, solvents, or fl ammable liquids shall be removed by an appropriate separator. Sand and oil separators shall be provided wherever fl oors, pits or surface areas subject to accumulation of grease or oil from service or repair operations are drained or washed into the drainage system, such as car or truck washing facilities, engine cleaning facilities and similar operations. Drains are only required in a parking garage if the facility has provisions for either washing vehicles or rinsing the fl oor, and they must be routed through a sand and oil separator. Where oil separators are required in garages and service stations, they shall be sized based on the square footage of the area drained. Oil separators in other applications shall be sized according to the manufacturers rated fl ow.
MODEL PLUMBING CODES
Illinois Plumbing Code (2005)10 – Commercial vehicle repair garages, gasoline stations with grease racks or pits and oil change facilities shall be provided with fl oor drains or trench drains connected to a gas and oil interceptor. Approved interceptor materials include cast iron, steel, polyethylene, polymer concrete or fi berglass. Fiberglass interceptors shall not be used for receiving any substance other than oil and gas and poured concrete interceptors are prohibited. Interceptors utilizing an automatic draw off feature must install a separate U.L. approved underground storage tank or storage tank integral with the interceptor. Gas and oil interceptors shall have a depth of at least 2 feet below the invert of the discharge drain and shall have at least a 12 inch water seal with a minimum 90% effi ciency rating or have a minimum of an 18 inch water seal. Sizing of gas and oil interceptors is based on the square footage of the facility.
Kentucky State Plumbing Law (2013)11 – Liquid waste from buildings using gasoline, benzene, naphtha or other infl ammable oils or compounds shall discharge into a separator before it enters a sanitary sewer. The waste line receiving the waste shall be trapped and vented. The separator shall be provided with a 3 inch vent.
Louisiana Plumbing Code (2013)12 – All repair garages and gasoline stations with grease racks or grease pits, and all factories which have oily wastes as a result of manufacturing, storage, maintenance, repair or testing processes shall be provided with an oil separator. The vapor compartment shall be independently vented to the outer air. Where an interceptor is provided with an overfl ow line, an approved waste oil tank having a minimum capacity of 550 gallons shall be installed. Sizing is either based on the number of vehicles serviced, stored or both. Where vehicles are serviced only, the sizing is based on the square footage of the facility.
Massachusett s Plumbing Code (2013)13 – Interceptors and separators shall be provided to prevent the discharge of oil, gasoline, grease, sand and other substances that are harmful or hazardous to the building drainage system, the public sewer or
sewage treatment plant or other sewage treatment processes. There shall be fl oor drains installed in all commercial motor vehicle parking and storage accommodations, repair garages, repair facilities or auto body repair facilities, service facilities with or without grease racks and grease pits, wash rack areas, wash areas (including automatic car wash structures), and facilities where motor oils, gasoline, anti-freeze and similar hazardous liquid wastes are potentially generated or may potentially spill. Floor drain wastes shall discharge into a gas, sand and oil separator.
Minnesota Plumbing Code (2012)14 – Enclosed garages of over 1,000 square feet or housing more than four motor vehicles, repair garages, gasoline stations with grease racks, work or wash racks, auto washes, and all buildings where oily and/or fl ammable liquid wastes are produced shall have a separator installed into which all oil, grease and sand bearing and/or fl ammable wastes shall be discharged. The separator shall be located inside the building. Each separator shall be not less than 35 cubic feet holding capacity, be provided with a water seal of not less than three inches on the inlet and not less than 18 inches on the outlet. The minimum depth below the invert of the discharge drain shall be three feet. The minimum size of the discharge drain shall be four inches. The separator may be constructed from concrete, iron or steel (protected with an approved corrosion resistant coating on both the inside and the outside), or of fi berglass resins that comply with ASTM C-581 and meets IAPMO PS 80-2003b.
Wisconsin Administrative Code (2013)15 – Oil and fl ammable wastewater that discharges to a building sewer shall be intercepted or treated by a means acceptable to the department. A covered interceptor or separator shall be provided with an individual vent of at least 3 inches in diameter and shall extend from the interceptor or separator at least 12 feet above grade. The drain pipe to the interceptor or separator shall be provided with a fresh air inlet connected within 2 feet of the inlet of the interceptor or separator and shall terminate at least one foot above grade but not less than 6 feet below the terminating elevation of the vent serving the interceptor or separator and shall be at least 3 inches in diameter.
