which requires a means of discharge, shall provide drainage for the
water as follows:
(a)
The installation of a sump pump that is discharged to the outside
of the building;
(b)
The interior portion of the discharge system must be a rigid
type permanent pipe connection that penetrates to the outside of the
building;
(c)
The discharge on the exterior side of the building can be a
permanent type or flexible type pipe, but must not discharge to the
Borough sewer system.
(d)
The discharge to the exterior side of the building must be directed
to a point on the property of the owner of the dwelling or other building,
and shall not be directed so as to cause a water or ice hazard or
nuisance on public or private property.
(3)
Information and Letter of Acceptance. Property owners may contact
the Advanced Waste Water Treatment Plant for information and inspection
concerning the status of their sump pump connections, sewer line clean-outs
and floor drains. A property owner desiring a Letter of Acceptance

[Ord. No. 2002-11]
A.
Description. The purpose of an interior grease interceptor (IGI)
or an exterior grease interceptor (EGI) is to remove grease or oil
from the influent prior to discharge to the sanitary sewer. Interceptors
serve as small flotation chambers where grease floats to the water
surface and is retained while the clearer water underneath is discharged.
Interceptors may also serve as grease recovery systems which operate
by heating the waste, liquefying the grease and skimming the grease
off the top into a receptacle. The use of the term "interceptor" is
interchangeable with the use of the word "trap."
B.
Commercial and Industrial Customers. All restaurants, cafeterias,
institutional kitchens and other installations having facilities for
the preparation and serving of food in quantity, and gas stations,
auto maintenance garages and car washes where, in the opinion of the
Borough Plumbing Subcode Official in agreement with the Superintendent
of the Advanced Wastewater Treatment Plant (AWWTP) and the Borough
Health Officer, the potential for discharge of grease and oils into
the sanitary sewer system exists, and who are customers of the Borough,
shall be required to install a grease interceptor. Requirements for
a grease trap may be waived if, in the opinion of the Borough Subcode
Official, Superintendent of the Advanced Wastewater Treatment Plant,
and Borough Health Officer, minimal or no grease will be generated.
C.
Special Requirements.
(1)
The size and type of grease interceptor and location of same shall
be subject to approval by the Borough Plumbing Subcode Official as
determined in (e) (2). The grease interceptor shall be installed in
a line separate from other sanitary plumbing facilities. In general,
all grease interceptors shall be designed for exterior installation
and shall be of sufficient capacity to service those grease generating
fixtures connected thereto. Wastes other than those requiring separation
shall not be discharged into any interceptor.
(2)
Waste lines from commercial dishwashers shall not be directed through
the grease interceptor, unless provided with a cooling chamber and
approved by the Hightstown Borough Plumbing Subcode Official. Dishwashers
shall provide a pre-rinse sink which must be directed through the
grease trap. A pre-rinse sink directed through an interceptor shall
be provided and located immediately adjacent to the dishwasher in
all new or remodeled retail food establishments.
D.
Location of Grease Interceptor.
(1)
Grease traps shall be installed in each line servicing fixtures into
which grease will be discharged. The interceptor shall be located,
designed and constructed in a manner that will permit easy access
and cleaning. Grease interceptors shall be located outside of the
establishment whenever possible.
(2)
Any new commercial or industrial customer, as defined above, will
be required to install an EGI unless:
(a)
The customer can demonstrate to the satisfaction of the Superintendent
of the AWWTP, Borough Health Officer and Plumbing Subcode Official
the quantity of grease discharge does not warrant an EGI based on
minimal discharge projections; or
(b)
The operation of an EGI would not be effective in the opinion
of the Plumbing Subcode Official due to the potential location of
the facility.
|
In either case, an internal grease interceptor shall be provided.
|
(3)
Any existing commercial or industrial customer, as defined above, operating without a grease interceptor receptacle of any type, will be required by the Plumbing Subcode Official to install a grease interceptor, in an exterior location as stipulated under Subsection H(1)(c) herein. Interior facilities will be considered based on the conditions stipulated under Subsection D(2) above.
E.
Interceptor Construction Features.
(1)
The minimum requirements for exterior interceptor construction, materials
and foundations for interceptors, required by the Plumbing Subcode
Official, shall be:
(2)
The size and design of an EGI will be based, at a minimum, on its
rated grease retention capacity which is determined by the amount
of grease (in pounds) that an interceptor can hold before its average
efficiency drops below 90.0%. (Grease retention capacity in pounds
should equal at least twice the flow capacity in gallons per minute.)
The following two equations shall be used to determine the minimum
size required for grease traps serving:
(a)
Restaurants:
|
Size of Grease = D x (HR/2) x (GL) x (ST) x (LF)
|
|
Interceptor in Gallons where:
|
|
D =Number of seats in dining area
|
|
GL = Gallons of wastewater per meal, normally 5
gallons
|
|
ST = Storage capacity factor - minimum of 1.7
|
|
HR = Number of hours open per day
|
|
LF = Loading factor depending on restaurant location:
|
|
-1.00 for recreation areas
|
|
-0.80 for main highways
|
|
-0.50 for other highways
|
|
-0.50 for all others
|
|
A restaurant, for example, with a 75-seat dining area, operating
eight hours per day, with a typical discharge of five gallons of wastewater
per meal, using a storage capacity factor of 1.7 and a loading factor
of 0.5, the size of a grease interceptor would be as follows:
|
|
Size of Grease = D x (HR/2) x (GL) x (ST) x (LF)
|
|
Interceptor
|
|
1,275 gal. = 75 x (8/2) x 5 x 1.7 x 0.5
|
(b)
Cafeterias, Hospitals, Nursing Homes, and Other Commercial Kitchens:
|
Size of Grease = M x (GL) x (ST) x (5/2) x (LF)
|
|
Interceptor in Gallons where:
|
|
M = Meals per day
|
|
GL = Gallons of wastewater per meal, normally 4.5
gallons
|
|
ST = Storage capacity factor - minimum of 1.7
|
|
LF = Load factor depends on type of facilities present:
|
|
-1.25 for dishwashing
|
|
-1.00 without dishwashing
|
|
A commercial kitchen, for example, serving 1,000 meals per day,
with a typical discharge of 4.5 gallons per meal, using a storage
capacity factor of 1.7, and a load factor of 0.5 (no dishwasher),
the size of the grease trap would be as follows:
|
|
Size of Grease = M x (GL) x (ST) x (5/2) x (LF)
|
|
Interceptor
|
|
9,562.5 gal. = 1,000 x 4.5 x 1.7 x 2.5 x 0.5
|
(3)
In no case will the exterior grease interceptor be less than 750
gallons in capacity, as stipulated in the National Plumbing Code.
(4)
The inlet and outlet of the grease trap shall be provided with "T"
baffles which extend to a depth of 12.0 inches above tank floor and
well above the liquid level.
(5)
To facilitate maintenance of EGI's:
(a)
Manholes extending to finished grade shall be provided;
(b)
Covers shall be of gas-tight construction and shall be designed
to withstand expected loads and to prevent access by children;
(c)
The inlet and outlet lines to a retention facility shall have
cleanouts that extend to finished grade; and
(d)
All plugs should be brass countersunk at grade.
(6)
In those cases where interior grease interceptor (IGI) facilities
are allowed, as stipulated in this section, the design criteria for
their installation shall include:
(a)
The IGI shall be required to have an approved rate of flow related
to the total number of the fixtures discharging into the unit as follows:
|
Required Flow Capacity of IGI Facility

|
(b)
The fixture capacity of a sink shall be calculated from the
fixture volume x 75% minimum fill divided by the drainage load of
one minute. Fixture drainage capacity of other than sinks shall be
determined from appropriate manufacturer's literature.
(c)
No more than four fixtures shall be connected to any one IGI.
(d)
Water cooled IGI's are prohibited.
(e)
Grease interceptors must be designed so that they will not become
air-bound if tight covers are used.
(f)
Flow control devices, if required, shall be installed at the
drain outlet of each grease-producing fixture, not at the inlet of
the IGI. In order to meet PDI standards, flow control devices that
are installed in the floor must be in a pit sized to allow easy access.
(g)
Flow control devices having adjustable (or removable) parts
are prohibited.
(h)
Interior grease interceptor facilities must be PDI-approved.
(7)
Where automobiles are serviced, greased, repaired, washed or where
gasoline is dispensed, separators shall have a minimum capacity of
six cubic feet for the first 100 square feet of area to be drained
plus one cubic foot for each additional 100 square feet to be drained
into the separator. Oil separators shall have a depth of not less
than two feet below the invert of the discharge drain. The outlet
opening of the separator shall have not less than an eighteen-inch
water seal.
(8)
Grease collected from a grease interceptor must not be introduced
into any drainage piping, public or private sewer.
(9)
No grease interceptor, interior or exterior, shall have any enzyme
or other opening for similar chemicals, nor shall it use automatic
or manual solvent dispensers.
(10)
Grease interceptors and separators must be maintained in efficient
operating condition by the periodic removal of accumulated grease.
Evidence of proper removal and disposal will be required.
F.
Pre-Existing Grease Interceptor Facilities. Any commercial or industrial
customers where grease interceptor facilities existed prior to the
adoption of Ordinance 2002-10 on June 3, 2002, will be exempt from
these grease interceptor requirements, except in those cases where
the Plumbing Subcode Official determines that the following conditions
exist:
(1)
Inadequate sizing of grease interceptor equipment;
(2)
Insufficient maintenance practices;
(3)
Evaluation of flow parameters from wastewater sources exceed grease
interceptor guidelines set forth in this section;
(4)
Plumbing system which separates grease interceptor facility from
remainder of sanitary system is not in place; or
G.
Maintenance.
(1)
To insure effective operation, grease interceptors will be located
close to the wastewater source and cleaned at or before the receptacle
reaches 75.0% of the grease-retention capacity but no less than every
three months. The operator of a grease interceptor shall keep a logbook
for inspection by all agencies having jurisdiction detailing all maintenance
actions and evidence of proper disposal from the disposal services
cleaning the retention receptacle.
(2)
Cleaning shall be performed in a manner that does not discharge grease
to the sewer main. Cleaning of sewer lines of grease buildup shall
include removal of grease from the sewerage system.
H.
Enforcement of Grease Interceptor Requirements.
(1)
Enforcement procedures will include:
(a)
All. Yearly inspection of all grease interceptor systems. Inspections
shall be performed by the Borough Health Officer or his/her designee.
(b)
New. Denial of application for sewer connection pending installation
of system.
(c)
Pre-Existing. For any commercial or industrial facilities that
are found to have grease interceptor systems which are inadequate
in accordance with this section, and which are connected to the Borough's
sanitary sewer system, and/or are in the process of changing owners,
leases, or renters, the fee simple owner will be required to:
[1]
Submit to an inspection of grease retention equipment by the
Plumbing Subcode Official in coordination with the Superintendent
of the AWWTP and the Borough Health Officer to determine adequacy
of system sizing;
[2]
Update the system before the new operator can initiate business;
[3]
Obtain all necessary approvals; and
[4]
