be required to install a grease trap/interceptor. All other commercial
and/or industrial establishments shall be required to install a grease
trap/interceptor when, in the reasonable opinion of the Health Officer,
Borough Sewer Department or Borough Plumbing Subcode Official, grease
traps/interceptors are necessary due to the type of activity/use of
the property. The following regulations and requirements shall apply
to all external or internal grease traps/interceptors where such grease
traps/interceptors are installed or required to be installed.
(2) Grease traps/interceptors shall be constructed of impervious materials,
capable of withstanding abrupt and extreme changes in temperatures.
They shall be watertight and substantially constructed and equipped
with readily removable access covers. The design and pertinent data
shall be submitted to the Borough Plumbing Subcode Official for review
and approval prior to construction or installation. Grease traps/interceptors
must be installed entirely on the property of the owner.
(3) Grease traps and interceptors shall be installed in accordance with
the Plumbing Subcode adopted by the Commissioner of Community Affairs
as set forth in the New Jersey Uniform Construction Code 5:23, Subchapter

lessee's, or assignee holder's expense, in continuous, efficient operation
at all times.
(5) It is the responsibility of the establishment owner, lessee or assignee
to carry out all proceedings necessary to have any and all grease
traps/interceptors opened at time of inspection and to see that the

of three certifications per year, not later than April 30, August
31 and December 31, from a service company that the grease trap/interceptor
has been properly installed, is properly maintained and is functioning
for its intended purposes ("certification"). "Seasonal facilities"
means those facilities that are not operating for a consecutive part
of the year. "Sporadic facilities" means those facilities which are
used at irregular intervals. All seasonal facilities and sporadic
facilities shall maintain their grease traps in operating condition
and shall submit the required certification to the Health Officer

of grease being emitted from the effluent line of the unit. All grease
traps/interceptors shall be cleaned in accordance with the foregoing
schedule and the Borough provided with a bill or receipt from a licensed
county-registered grease and waste disposal company or qualified recycling
company. Disagreeable odors shall require deodorant to combat said
offensive odors.
(10)
In addition to the Borough's other remedies, should the Borough
or its agents incur costs to clean the sewer laterals or sewer lines
in the vicinity of the food service establishment due to grease, fats
and/or oils, and/or in otherwise responding to a backup caused by
such grease, fats and/or oils, whether or not the restaurant, cafeteria,

The admission into the public waters of any waters or wastes having a BOD greater than 300 parts per million by weight or containing any quantity of substances having the characteristics described in §
332-9 or having an average daily flow greater than 2% of the average daily sewage flow of the Borough shall be subject to the review and approval of the Borough Engineer. Where necessary in the opinion of the Borough Engineer or required by the Middlesex County Utilities Authority, the owner shall provide, at his expense, such preliminary treatment as may be necessary to reduce the BOD to 300 parts per million and the suspended solids to 350 parts per million by weight, to reduce objectionable characteristics or constituents to within the maximum limits provided for in §
332-9 or to control the quantities and rates of discharge of such waters or wastes. Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Borough Engineer and of the State Department of Health of New Jersey, and no construction of such facilities shall be commenced until said approvals are obtained in writing.

to stop and prevent at any time the discharge into sewers or laterals
of any waste which may injure the sewers or adversely affect sewage
treatment or which is not in conformity with the requirements and
the standards now or hereafter made by the Borough or the Middlesex
County Utilities Authority, and the Borough of Middlesex may, at any
time, without notice and without recourse, sever the connection and

shall not apply to water from ordinary hot-water boilers.
B. So far as practicable, industrial wastes may be discharged
into the municipal sewerage system, with a minimum of or without pretreatment,
provided that the consent of the Mayor and Council of the Borough
of Middlesex is first had and obtained and the rules, regulations
and charges herein fixed or otherwise prescribed are complied with.
(1) The charge for factory effluents or industrial wastes

[Amended 6-11-1958 by Ord. No. 290]
[1]
Be of such a nature and such a quantity as to
impair the hydraulic capacity of such facilities, normal and reasonable
wear and usage excepted.

or mechanical action, impair the strength or the durability of the
sewer structures.

[Amended 11-13-1957 by Ord. No. 277]
In the event that the materials, chemical properties
or characteristics of wastes from any industry interfere with the
efficiency of the municipal sewerage system or unduly increases the
cost of maintenance thereof, then, said industry shall, by reducing
its peak discharges, by construction of equalizing tanks, by partial
pretreatment, by elimination of troublesome wastes or by other approved
means, produce wastes of acceptable quality before discharge to the
municipal system.
[Amended 11-13-1957 by Ord. No. 277]
It is the intention of these rules and regulations
to allow maximum latitude in the use of the municipal system, and
to require control or special procedure by industry only in such cases
as the failure to do so would seriously affect the operation or maintenance
of the municipal sewerage system, or would entail unwarranted expenditures
therefor by the municipality.
[Amended 11-13-1957 by Ord. No. 277]
Each industry shall have, or install a suitable
device for continuously recording the flow to be discharged to the
municipal system. Plans for complete metering installation, or other
means of flow control, shall be submitted to the municipality for
approval.
[Amended 11-13-1957 by Ord. No. 277]
A. Means shall be provided at each plant to allow periodic
sampling to determine the character and concentration of wastes as
a basis for charges for biochemical oxygen demand, suspended solids
and chlorine demand. Such determinations will be made as often as
deemed necessary. Determination of character of the wastes will be
made by the municipality and shall be binding as a basis for charges.
B. In the event that the character of the wastes as discharged
do not provide representative data as to actual costs, then charges
shall be based upon full scale tests by the municipality or upon estimates
based upon representative data.

truly representative of the actual quality of wastes, and standard
methods of analysis will be used.

charges shall be subject to revision.
All stables, garages, factories and milk depots
and similar establishments, in which floor drains are to be connected
with the main line sewer, shall be provided with catch basins or sand
traps to receive and retain all sand, dirt and other refuse which
would tend to clog the building or sewer. The catch basin or sand
trap shall have a cover of ample size which can be easily opened and
the sand or refuse shall be removed at sufficiently frequent intervals
to keep the deposits below the bottom of the outlet pipe.
Where any sand traps now in use are, in the
opinion of the Plumbing Inspector of the Board of Health, incapable
of performing the work for which they are intended, such sand traps
shall be removed and new sand traps shall be constructed in accordance

and approval of the duly authorized municipal officer. Individual
property owners may make sewer connections to the main sewer where
the branch sewer has heretofore been connected to the main sewer and
brought to the curb, provided, however, that such connection made
to the main sewer by individual property owners must conform to the
"Specifications for the construction of service connections to the
sewers in the Borough of Middlesex, New Jersey," and shall be subject
to the like inspection and approval as above.
The owner or owners of property at which location
any work is done under this article shall be wholly responsible for
any damages to property or personal injury as a result of such work.
Wherever connections shall be made with the
sanitary sewer system of the Borough of Middlesex and before the trench
