[Ord. No. 1226, § I, 6-23-2020]
(a) No person or business shall uncover, make any connections with or
opening into, use, alter or disturb any public sewer or appurtenance
thereof without first obtaining a written permit from the Commissioner.
(b) Any person or business proposing a new discharge into the system
or a substantial change in the volume or character of pollutants that
are being discharged into the system shall submit a permit application
to the Commissioner at least 120 days prior to the proposed change
or connection. The applicant shall be responsible for costs incurred
by the City to evaluate the capacity of existing collection system
and treatment plant to accommodate proposed changes.
(c) Where existing or proposed wastewater discharges do not meet applicable
pretreatment standards or requirements or where such contributions
would cause the WWTP to violate its NPDES permit, the Commissioner
shall prohibit or place conditions on such contributions to ensure
compliance with pretreatment standards or to prevent interference
or pass through.
[Ord. No. 1226, § I, 6-23-2020]
There shall be two classes of building sewer permits: (a) for
residential and commercial service, and (b) for service to establishments
producing industrial wastes, including significant industrial users
as defined herein and any other establishment discharging or proposing
to discharge wastes containing toxic pollutants or wastes having the
potential for significant impact, either singly or in combination
with other contributing industries, on the wastewater treatment system,
the quality of sludge or other wastewater treatment residuals, the
WWTP's effluent quality, or air emissions generated by the WWTP.
Within 180 days after the effective date of any categorical
pretreatment standard or a category determination by the control authority,
whichever is later, or, in the case of a new source of industrial
waste as defined herein, not later than 90 days prior to introducing
wastes into the wastewater system, industrial users subject to such
pretreatment standards or requirements shall submit a baseline monitoring
report to the Commissioner.
Permits for industrial users shall be issued for a period not
to exceed three years; be nontransferable without the prior and express
written approval of the Commissioner; and, as a minimum, include effluent
limits based on applicable general pretreatment standards, categorical
pretreatment standards, local limits, and state and local law; include
requirements for self-monitoring, sampling, reporting, notification
and recordkeeping, including an identification of the pollutants to
be monitored and the sampling frequency, type and location; and any
other requirements.
Nothing in this section shall be construed as to require the
issuance of any permit to any industrial user or to relieve any industrial
user from any responsibility or requirement to make proper application
for such permit. No industrial wastewater shall be discharged to the
wastewater system by any new source until a permit has been issued
by the Commissioner.
Permits may be revoked by the City for a violation of this chapter,
the pretreatment regulations adopted by the City, or applicable state
and federal regulations.
[Ord. No. 1226, § I, 6-23-2020]
(a) All costs and expense incident to the installation and connection
of the building sewer shall be borne by the owner. The owner shall
indemnify the City from any loss or damage that may directly or indirectly
occur by the installation of the building sewer.
(b) At the time of obtaining a permit, the owner or their designated
contractor shall furnish to the City evidence of liability insurance
with respect to injuries to persons or property that may arise during
the construction of the building sewer in limits of not less than
$1,000,000 for bodily injury to persons per occurrence and $500,000
for injury to property of third persons. The owner shall further post
with the treasurer a cash or surety bond in an amount deemed sufficient
by the Commissioner to ensure restoration of the travelled portion
of the public way or unaccepted way, including sidewalks if any, to
their condition prior to construction following completion of the
work required to complete the sewer connection.
[Ord. No. 1226, § I, 6-23-2020]
A separate and independent building sewer shall be provided
for every building; except where one building stands at the rear of
another or an interior lot and no private sewer is available or can
be constructed to the rear building through an adjoining alley, court,
yard or driveway, the building sewer from the front building may be
extended to the rear building and the whole considered as one building
sewer. Such exceptions may be only undertaken with written approval
of the Commissioner.
[Ord. No. 1226, § I, 6-23-2020]
Existing building sewers may be reused in connection with new
buildings only when they are found, on examination and test by the
Commissioner, to meet all requirements of this chapter. The sewers
must, in addition, be proven watertight and possess the structural
integrity adequate to meet all design standards. At the discretion
of the Commissioner, the proponent may be required to perform a sewer
capacity analysis, at the expense of the proponent and under the oversight
of the City. The costs associated with the testing and examination
of existing building sewers shall be borne by the building sewer owner.
[Ord. No. 1226, § I, 6-23-2020]
The size, slope, alignment, materials of construction of a building
sewer, and the methods to be used in excavating, placing of the pipe,
jointing, testing, and backfilling the trench shall all conform to
the requirements of the building and plumbing code or other applicable
rules and regulations of the City. In the absence of code provisions
or in amplification thereof, the materials and procedures set forth
in appropriate specifications of the Gravity Sanitary Sewer Design
and Construction, Second Edition ASCE Manuals and Reports on Engineering
Practice No. 60/WEF Manual of Practice No. FD-5, or materials and
procedures specifically provided by the City, shall apply. All new
sewers shall be designed and constructed in accordance with state
regulations, and tested for infiltration in accordance with an acceptable
testing method of the State Department of Public Health.
[Ord. No. 1226, § I, 6-23-2020]
Subject to the elevation of the public sewer, buildings in which
the building sewer is too low to permit gravity discharge to the public
sewer, the building sewer shall be pumped by an approved means and
discharged to the public sewer. Appurtenances installed to pump building
sewers to the public sewer shall be installed and maintained at the
building sewer owner's expense.
[Ord. No. 1226, § I, 6-23-2020]
The City assumes no liability for conditions that exist in plumbing
fixtures, building sewers and appurtenances that may result from surcharge,
repair, and operation and maintenance activities performed by the
City on the public sewer. All existing or new building sewers from
plumbing fixtures liable to backflow from the public sewer are installed
at the building owner's risk. The City will not assume any responsibility
for back-ups or flooding of fixtures or basements as a result of the
installation of these fixtures. Any plumbing fixture located at an
elevation lower than the top of the public sewer manhole immediately
downstream of the building sewer serving the fixture shall be considered
to be liable to backflow.
Plumbing fixtures subject to backflow from the public sewer
shall have backwater valves installed at the building sewer owner's
expense. A backwater valve is a device installed in a building sewer
to prevent the discharge from the building, or flows originating outside
the building, from flowing back into the building. Backwater valves
shall be installed in accordance with the Uniform State Plumbing Code,
248 CMR, Section 2.09:(4) and City requirements. The backwater valve
shall be installed and maintained at the building sewer owner's expense.
[Ord. No. 1226, § I, 6-23-2020]
No person shall make connections of roof downspouts, exterior
foundation drains, foundation sump pumps, areaway drains or other
sources of surface runoff or groundwater to a building sewer which
in turn is connected directly or indirectly to a public sanitary sewer.
[Ord. No. 1226, § I, 6-23-2020]
The connection of the building sewer into the public sewer shall
conform to the requirements of the building and plumbing code or other
applicable rules and regulations of the City, or the procedures set
forth in appropriate specifications of the ASTM and the WEF Manual
of Practice No. 9. All such connections shall be made gastight and
watertight. Any deviation from the prescribed procedures and materials
must be approved by the Commissioner before installation.
[Ord. No. 1226, § I, 6-23-2020]
The applicant for the building sewer permit shall notify the
Commissioner when the building sewer is ready for inspection and connection
to the public sewer. The connection shall be made under the supervision
of the Commissioner or their duly authorized representative.
[Ord. No. 1226, § I, 6-23-2020]
All excavations for building sewer installation shall be adequately
guarded with barricades and lights so as to protect the public from
hazard. Streets, sidewalks, parkways and other public property disturbed
in the course of work shall be restored to their pre-construction
condition, prior to completion of the work in a manner satisfactory
to the City. Trench excavations shall conform to applicable federal
and state regulations.
