No unauthorized person shall uncover, make any
connections with or opening into or use, alter or disturb any public
sewer or appurtenance thereof without first obtaining a written permit
from the Sewer and Water Superintendent.
All costs and expenses incident to the installation
and connection of the building sewer shall be borne by the owner.
The owner shall indemnify the Town from any loss or damage that may
directly or indirectly be occasioned by the installation of the building
sewer.
A separate and independent building sewer shall
be provided for every property, except that, 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 building sewer from the front
building may be extended to the rear building and the whole considered
as one building sewer.
Old building sewers may be used in connection
with new buildings only when they are found, upon examination and
test by the Sewer and Water Superintendent, to meet all requirements
of this Part 1.
[Amended at time of adoption of Code (see Ch. 1, General

[Amended 4-3-2018 by L.L.
No. 04-2018]
A. Whenever
possible, the 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 to the public sewer,
sanitary sewage carried by such building drain shall be lifted by
an approved means and discharged to the building sewer.
B. Backwater
valves.
(1) Where
required:
(a) Fixtures and/or drain inlets subject to backflow and flooding from
blocked or restricted public sewers shall be protected by a backwater
valve.
(b) Such situations include those where the flood level rim of fixtures
and/or drain inlets are below the overflow level of the first upstream
manhole in the public sewer that will overflow due to a blockage or
flow restriction in the public sewer.
(c) Any sanitary fixture installed in a building at an elevation lower
than the curb or street, whichever is higher, must include backflow
prevention to eliminate potential flooding of the premises with sewage.
(d) Backwater valves shall be installed at the property owner's expenses
on all sewer laterals when such valves are required for that location.
(e) Any property in the Town of Thompson which requires the installation
of backwater valves but was constructed prior to passage of this requirement
shall have a period of not more than 12 months to complete said installation
of approved backwater valves pursuant to this section.
(2) Material
standard and accessibility. Backwater valves shall conform to ASME
A112.14.1 and be installed so that their internal working parts are
accessible for periodic cleaning, repair or replacement.
No person shall make connection of roof downspouts,
exterior 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.
[Amended at time of adoption of Code (see Ch. 1, General
Provisions, Art. I)]
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 Town
or the procedures set forth in appropriate specifications of ASTM
International and the Water Pollution Control Federation 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 Sewer and Water Superintendent
before installation.
The applicant for the building sewer permit
shall notify the Sewer and Water Superintendent when the building
sewer is ready for inspection and connection to the public sewer.
The connection shall be made under the supervision of the Sewer and
Water Superintendent or his representative.
