No unauthorized person(s) 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 Town.
There shall be two classes of building sewer permits: for residential
and commercial service producing only domestic wastewater (or sanitary
sewage) as defined herein, and for service to establishments producing
industrial wastes and commercial facilities that produce a process
wastewater effluent or discharge. Commercial facility may include
but not be limited to: office buildings, medical centers including
dental facilities, restaurants, food service facilities, hotels, malls,
retail stores, farm land, multifamily housing buildings, warehouses,
septage haulers, and garages. In either case, the owner(s) or agent
shall make application on a special form furnished by the Town. The
permit application shall be supplemented by any plans, specifications,
or other information considered pertinent in the judgment of the Town.
A permit and inspection fee, as established by the Town Council from
time to time, for a residential or commercial building sewer permit
shall be paid to the Town at the time the application is filed. The
permit and inspection fee for industrial service and commercial facilities
that produce a process wastewater effluent or discharge shall be based
on the actual cost to the Town.
A. The Town may stipulate special conditions and terms upon which the
industrial user permit is predicated, and this may include, but shall
not be limited to, the following:
(1) Limitation on quantity, rate of discharge and wastewater characteristics.
(2) Installation of flow monitoring and sampling facilities.
(3) Requirements for monitoring programs (including monitoring waivers approved in accordance with §
158-44, Monitoring), including flow measurement, wastewater sampling and analysis and schedule for reporting and submission of data. The Town will review the data furnished and has the authority to request additional information if required.
(4) Pretreatment requirements, including schedules of compliance and
progress notification.
(5) Special fees and service charges.
(6) Wastewaters discharge peak rate and volume over a specified time
period.
(7) Chemical analyses of wastewaters.
(8) Information on raw materials, processes, and products affecting wastewater
volume and quality.
(9) Quantity and disposition of specific liquid, sludge, oil, solvent,
or other materials important to sewer use control.
(10)
A plot plan of sewers on the user's property showing sewer
and pretreatment facility location.
(11)
Details of wastewater pretreatment facilities.
(12)
Details of systems to prevent and control the losses of materials
through spills to the municipal sewer.
(13)
Other requirements to comply with federal, state and local regulations.
B. Discharge permits shall not be transferred or reassigned.
C. A permit expiration date can be extended and will remain enforceable
if the permit is not reissued provided the permittee complies with
the following:
(1) The permittee has submitted a complete permit application at least
60 days prior to the expiration date of the user's existing permit;
and
(2) The failure to reissue the permit prior to expiration of the previous
permit is not due to any act or failure to act on the part of the
permittee.
(3) The extension shall not exceed one-year period or 365 days.
D. It is the responsibility of the permittee to ensure that all the
characteristics of the wastewater have been fully disclosed. The permittee
shall certify that there are no material omissions or misrepresentations
in the application hereto and that neither the application nor the
attached information contains any untrue statement of a material fact
or omit to state any material facts necessary to issue a wastewater
discharge permit. Permittees shall be subject to the remedies, including
penalties for failure to disclose.
All costs and expenses incidental to the installation, maintenance
and connection of the building sewer shall be borne by the owner(s).
The owner(s) shall indemnify the Town from any loss or damage that
may directly or indirectly be occasioned by the improper maintenance
or installation of the building sewer. Furthermore, the building owner
is responsible for all costs of maintenance, cleaning and repair of
the lateral connection from the sewer main to the building. All costs
and expenses incidental to the installation, maintenance, cleaning
and connection of the building sewer shall be borne by the owner(s).
The owner(s) shall indemnify the Town from any loss or damage that
may directly or indirectly be occasioned by the installation and maintenance
of the building sewer, including the proper installation, maintenance
and cleaning of backflow preventers (check valve) and building laterals
where the building lateral fails or develops a blockage.
Unless specifically authorized by the Town, a separate and independent
building sewer shall be provided for every building, except where
one building stands at the rear of another on 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 front building
sewer may be extended to the rear building and the whole considered
as one building sewer, but the Town does not and will not assume any
obligation or responsibility for damage caused by, or resulting from,
any such single connection aforementioned.
Old building sewers may be used in connection with new buildings
only when they are found, on examination and testing by the Town,
to meet all requirements of this chapter. All costs of such testing
and inspection, including any pipeline video recording [see Town Public
Works Department (PWD) Construction Standards for testing requirements],
shall be borne by the owner(s).
The size, slope, alignments, 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 Town's Building and Plumbing
Codes and the appropriate sections of the Town's standard specification
for sewer construction. In the absence of code provisions or in amplification
thereof, the materials and procedures set forth in appropriate specifications
of the latest edition of the ASTM Water Environment Federation Manual
of Practice No. 9 shall apply.
Whenever possible, any building sewer shall be brought to the
building at an elevation below the basement floor. In all buildings
in which any building drain is too low to permit gravity flow from
the sanitary facilities to the public sewer, sanitary sewage carried
by such building drain shall be lifted by an approved means and discharged
to the building sewer at the owner's expense.
No person(s) shall make connection of roof downspouts, foundation
drains, areaway drains, or other sources of surface runoff or groundwater
to a building sewer or building drain which, in turn, is connected
directly or indirectly to a public sanitary sewer.
The connection of the building sewer into the public sewer shall
conform to the requirements of the Town's Building and Plumbing
Codes and other applicable rules and regulations of the Town or the
procedures set forth in appropriate specifications of the ASTM and
the Water Environment Federation Manual of Practice No. 9. All such
connections shall be made gastight and watertight and verified by
Town inspection. Any deviation from the prescribed procedures and
materials must be approved by the Town before installation.
The applicant for the building sewer permit shall notify the
Town when the building sewer is ready for inspection and connection
to the public sewer. The connection and testing shall be made under
the supervision of the Town.
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 in a manner satisfactory to
the Town at the expense of the owner.
A. Any person proposing a new discharge into the system or an increase
in the volume, beyond limits previously permitted, or in the strength
or character of pollutants that are discharged into the system shall
make application to the Town at least 60 days prior to the proposed
change or connection. No person shall operate with such an increase
or change without first having received a modification to his permit.
Proposed new discharges from residential or commercial sources involving
loading exceeding 50 population equivalents (5,000 gpd) or any extensions
of the sanitary sewer collection system with eight-inch pipe or larger,
including manholes, etc., any new industrial discharge, or any alteration
in either flow or waste characteristics in industrial discharge may
require approval by the New Hampshire Department of Environmental
Services (NHDES).
B. In the event a permittee intends to cease to discharge from a regulated
process or plans to disconnect from the wastewater system, the Public
Works Director must be notified no later than 60 days prior to commencement
of any action by the permittee. The notification shall provide a closure
management plan that includes the following information, as a minimum:
(1) Date of planned disconnect;
(2) Methods of disposal of regulated process tanks, chemicals, sludges,
plating wastes, cleaning solutions;
(3) Methods of cleaning tanks, barrels or other vessels containing regulated
pollutants;
(4) Names of carriers and ultimate disposal site(s) of the regulated
pollutants and the EPA permit numbers for transportation of the wastes,
if a permit is required by the EPA.
C. The permittee shall be responsible for all discharges to the wastewater system and shall not be disconnected until the Director or his/her designee has determined the permittee has disposed of the regulated wastes in a proper and safe manner and has requested termination of the discharge permit in writing. The permit shall be terminated in accordance with §
158-59C.
