No unauthorized person shall uncover, make any
connection with or opening into, use, alter or disturb any public
sewer or appurtenance thereof without first obtaining a written permit
from the Superintendent.
No person shall discharge or cause to be discharged
any stormwater, cooling water or unpolluted industrial waters to any
sanitary sewer. Swimming pool drains shall not be connected to any
sanitary sewer.
A. There shall be two classes of sewer lateral permits:
(1) For residential, commercial and institutional service.
(2) For service to establishments producing industrial
wastes.
B. In either case, a permit application shall be submitted
to the Superintendent. The permit application shall be supplemented
by any plans, specifications or other information considered pertinent
in the judgment of the Superintendent. A fee for residential, commercial,
institutional and industrial users, as established by the City Council,
shall accompany the application.
C. Connections to existing manholes shall be made as
directed by the Superintendent.
A. A separate and independent building lateral shall
be provided for every building requiring sanitary facilities. When,
however, there is a building behind a front building, the second building
may use the front building's building lateral if there is no other
way to provide sanitary service to the back building. All such buildings
will be under one ownership.
B. New building laterals and/or building laterals shall
not go under building basements. In like fashion, a building shall
not be constructed over an existing lateral; the lateral shall be
relocated after the Superintendent has approved plans showing the
relocation. If relocation is not physically possible, then the lateral
shall be:
(1) Exposed and totally encapsulated in not less than
three inches of concrete; or
(2) Exposed and walled and the building rooms above positively
ventilated outdoors.
C. All existing manholes in or under the basement shall
be sealed airtight in a manner acceptable to the Superintendent. No
new manholes shall be constructed on the portion of the lateral under
the building.
D. All building laterals which serve more than one residential
or commercial building prior to effective date of this Part 2 will
not be subject to separate and independent clause. Separation will
occur if all owners are in agreement and at their expense.
When building laterals are to serve multiple
structures, the building lateral shall be sized in accordance with
the metered water use and with sound professional engineering judgment.
Where a lateral sewer is to serve a complex of industrial, commercial, institutional or dwelling structures, special design of the building lateral system shall be required. Such lateral sewer shall be connected to the public sewer through a manhole. The Superintendent shall determine if and where this connection to the public sewer is required. If required, a new manhole shall be installed in the public sewer pursuant to §§
174-36 and
174-112, and the lateral connection made and tested as directed by the Superintendent. Plans and specifications shall be prepared and submitted for approval pursuant to this Part
2.
Dry sewers shall be designed and installed in
accordance to this Part 2.
Existing building laterals may be used in connection
with new buildings only when they are found, on examination by the
Superintendent, to meet all requirements of this Part 2.
Building and building lateral pipe materials
shall be one of the following:
A. Tar-coated, service grade, cast-iron soil pipe conforming
to ASTM Specification A-74, Cast Iron Pipe and Fittings. All dimensions,
weight and markings of the pipe shall conform to the requirements
of ANSI Designation A112.5.1, except spigot ends shall be "plain end,"
if gasket joints are used.
B. Polyvinyl chloride (PVC) pipe and fittings conforming
to ASTM Specification D-3034-73, SDR-35 Polyvinyl Chloride (PVC) Sewer
Pipe and Fittings. All pipe shall be suitable for gravity sewer service.
Provisions shall be made for contraction and expansion at each joint
with a rubber ring. The bell shall consist of an integral wall section
stiffened with two PVC retainer rings which securely lock the solid
cross-section ring into position. Minimum pipe stiffness (F/Y) at
5% deflection shall be 46 psi when tested in accordance with ASTM
Specification D-2412.
C. Any part of the building or building lateral shall
not be located within four feet of a water main or water service.
A. At the point of connection of a building lateral to
a public sewer, a standard Y-fitting and sufficient 1/8 (45°)
bend fittings shall be used. The Y-fittings shall be installed so
that flow in the arm shall transition smoothly into the flow in the
public sewer. No lateral connection shall be made to the public sewer
which permits the flow into the public sewer from the lateral to enter
at right angles.
B. The inside diameter of the fittings shall be same
diameter as the building lateral inside diameter.
The building lateral, including the Y- and 1/8
bend fittings, shall be connected to the main sewer at the time of
constructing the main sewer for each proposed lot for either immediate
or future development. Laterals installed for future development shall
be fitted with a standard plug approved for use by the Superintendent.
The location of all lateral connections shall be field-marked with
a two-inch by six-inch corrosion- and rot-resistant board. The marker
board shall extend from the depth of the lateral to a minimum of two
feet above grade. The location of all lateral connections shall be
indicated on a drawing with a minimum of three tie lines indicated.
Four copies of this drawing, showing the as-built location of these
connections, shall the furnished to the Superintendent. A refundable
deposit shall be placed with the City to assure receipt of these as-builts.
The deposit shall be placed when application is made; the amount of
the deposit shall be $100 per sheet of plans showing locations of
lateral connections. No sanitary sewer shall be accepted by the City
until four copies of this record drawing have been so filed with the
Superintendent, and the Superintendent has approved the submitted
drawings.
When any building lateral is to serve a school, hospital or similar institution, or public housing, or is to serve a complex of industrial or commercial buildings or which, in the opinion of the Superintendent, will receive wastewater or industrial wastes of such volume or character that frequent maintenance of said building or building lateral is anticipated, then such building lateral shall be connected to the public sewer through a manhole. The Superintendent shall determine if and where this type of connection to the public sewer is required. Connections to existing manholes shall be made as directed by the Superintendent. If required, a new manhole shall be installed in the public sewer pursuant to §§
174-37 and
174-112, and the lateral connection made thereto as directed by the Superintendent.
A. Building laterals laid parallel to a bearing wall
shall not be installed closer than three feet to such wall. The building
lateral shall enter the basement through the basement wall no less
than 12 inches above the basement floor. In no event shall any building
lateral be placed below the basement floor, except with the expressed
written approval of the Superintendent.
B. The building lateral shall be laid at uniform grade
and in straight alignment insofar as possible. Changes in direction
shall be made only with properly curved pipe and fittings. Changes
of direction of 90° or greater shall be made with a cleanout which
extends to grade, terminating in a terminal box set in concrete. In
building laterals, said cleanouts shall be provided such that the
maximum distance between cleanouts is 50 feet. The ends of all building
or building laterals, which are not connected to the interior plumbing
of the building for any reason, shall be sealed against infiltration
by a suitable stopper, plug or by other approved means.
In all buildings in which any building drain
is too low to permit gravity flow to the public sewer, wastewater
carried by such drain shall be lifted by mechanical means and discharged
to the building lateral, on approval of the Superintendent.
All excavations required for the installation
of a building lateral shall be open trench work unless otherwise approved
by the Superintendent. Pipe laying and backfilling, regardless of
pipe material used, shall be performed in general accordance with
Paragraphs 3 through 10 of ASTM Specification C-12, except that trench
width measured at the top of the installed pipe shall not exceed the
outside pipe diameter, plus 14 inches, and except that no backfill
shall be placed until the work has been inspected. The depth of cover
over the pipe shall be sufficient to afford protection from frost,
but no in any case shall such depth be less than four feet. Where
it is physically impossible to provide cover of four feet, the depth
may be reduced to a minimum of two feet and the pipe shall be insulated,
as approved by the Superintendent.
All joints and connections shall be made watertight.
Premolded gaskets may be used for hub and plain-end
cast-iron pipe joints and joints with fittings, if approved by the
Superintendent. The gasket shall be a neoprene compression-type unit
which provides a positive seal in the assembled joint. The gasket
shall be a premolded, one-piece unit designed for joining the cast-iron
hub and plain-end soil pipe and fittings. The assembled joint shall
be sealed by compression of the gasket between the exterior surface
of the spigot and the interior surface of the hub. The joint shall
be assembled following the manufacturer's recommendations using acceptable
lubricant and special pipe-coupling tools designed for that purpose.
The plain spigot end shall be forced into the hub end of the pipe
for the full depth of the hub itself. Lubricant shall be a bland,
flax-base, nontoxic material and shall not chemically attack the gasket
material.
Joints for PVC sewer pipe shall follow the manufacturer's recommendations, using properly designed couplings and rubber gaskets, pursuant to the published information relating thereto, and conforming to the applicable ASTM specification identified in §
174-57.
A. The connection of the building lateral shall be made
at the public sewer.
B. The cost of constructing the building lateral from
the existing public sewer to the building line shall be at the property
owner's expense; all subsequent costs and expense incidental to the
installation and connection of the building lateral shall also be
borne by the owner.
C. The property owner shall indemnify the City from any
loss or damage that may directly or indirectly be occasioned by the
installation of the building lateral.
D. It shall be the responsibility of the property owner
to maintain, repair or replace the building lateral, as needed.
E. The method of connection of the building lateral to
the public sewer will be dependent upon the type of sewer pipe material,
and, in all cases, shall be approved by the Superintendent. Any subsequent
repairs to new building laterals shall be at the property owner's
expense and be made by the City or an approved contractor.
The City is not responsible for repair/replacement
of cleanouts.
Any existing building lateral which, upon examination
by the Superintendent, is determined to be in need of replacement
will be replaced with a new building lateral. The replacement building
lateral shall be constructed by an approved contractor. The cost of
constructing the replacement building lateral shall be at the property
owner's expense.
The building lateral shall be tested for infiltration/exfiltration by any full pipe method described in §§
174-38 through
174-44 or by a suitable joint method with the prior written approval of the Superintendent.
The applicant for the building lateral permit
shall notify the Superintendent when the building lateral is ready
for inspection and connection is to be made to the public sewer. The
connection shall be made under the supervision of the Superintendent.
Before the trenches are backfilled, the person
performing such work shall notify the Superintendent when the laying
of the building lateral is completed, and no backfilling of trenches
shall begin until approval is obtained from the Superintendent.
All excavations for constructing building laterals
shall be adequately protected with barricades and lights so as to
protect the public from hazard. Streets, sidewalks, parkways and other
public property disturbed in the course of the work shall be restored
in a manner satisfactory to the Superintendent. When installation
requires disturbance of paved public roads and shoulders, restoration
shall involve road and shoulder restoration to City standards.
A. An exterior clean-out fitting shall be provided for
each building lateral at a readily accessible location, preferably
just outside the basement wall. The fitting shall contain a forty-five-degree
branch with removable plug or test tee and be so positioned that sewer-cleaning
equipment can be inserted therein to clean the building lateral.
B. The cleanout diameter shall be no less than the building
lateral diameter.
All costs associated with the provisions of
this article shall be borne by the property owner unless specifically
stated or agreed to be a cost borne by the City. The property owner
shall indemnify the City from any loss or damage that may be directly
or indirectly occasioned by the installation of the building laterals
and connections and appurtenances.
A. Before commencing work, the above contractor shall
file insurance certificates with the City Clerk for the following:
(1) (1)Workers' compensation and employers' liability
insurance as required by the laws of the state covering the contractor.
(2) Bodily injury liability having limits of not less
than $1,000,000 each occurrence and $1,000,000 aggregate (completed
operations/products, personal injury).
(3) Property damage liability having limits of not less
than $1,000,000 for all damages arising during the life of the contract
and shall include, but not be limited to, the following designated
hazards:
