Except where this Part 1 imposes a stricter standard or regulation,
all work requiring a permit hereunder and all installations made and
materials used in connection therewith shall comply with the Village
of Bannockburn Plumbing Code.[1]
[Amended 1-12-1981 by Ord. No. 81-04]
A.
B.
Connections.
(1)
Existing wyes. Connection of all service connection lines into
the Village sewerage system shall, whenever possible, be made to an
existing wye branch, "tee," or riser with an approved compression
coupling. All such connections shall be gas-tight and water-tight.
Any deviation from the prescribed procedures and materials must be
approved by the Commissioner before installation.
(2)
Nonexisting wyes. In the event wye branches or "tees" are not
available in the Village sewerage system, such fittings may be installed
only by special permission of the Water and Sewer Commissioner, by
an approved contractor, at the sole cost and expense of the sewer
customer. When wye branches or "tees" are not available for new service
connections, the contractor shall make a smooth, round hole machine-drilled
into the Village sewerage system sewer for inserting a saddle-type
fitting. The connector shall fit perfectly the contour of the inside
of the collector sewer and shall fit the particular size fitting into
the Village sewer into which the connection is made. No projection
of the fitting into the Village sewer shall be permitted. The space
between the shoulder of the fitting and the face of the Village sewer
line shall be completely filled with joint material which shall be
gas-tight and waterproof. The contractor shall furnish the Commissioner
with the exact location of the new service connection into the existing
main.
(3)
Deep connections. Service connections to Village sewers which
are 10 feet or more below grade shall be made by step excavations
in a trench sloping at 45° from the horizontal. The sloping risers
shall be encased in Class X concrete and shall extend four inches
either side of the service connection line to prevent damage during
backfilling. Instead of the sloping riser, the contractor may use
a vertical pipe riser, encased in Class X concrete, from the Village
sewer. Connections to either type of riser shall be by means of a
long sweep curve fitting.
(4)
Bedding and trench protection.
(a)
The pipe bedding shall be placed so that the entire length of
the pipe will have full bearing. No block of any kind shall be used.
(b)
All pipes will be bedded using four inches of granular material
below the pipe. Then, additional granular material or crushed stone
shall be placed to six inches above the pipe to protect it during
backfilling. A clay barrier, 10 feet long and having a height equal
to the trench, must be located just inside the property line to retard
drainage along the service trench.
(5)
Backfill.
(a)
Any excavation located in the area of an existing street, sidewalk,
or driveway shall be backfilled above the top of the granular cradle
to the level of the bottom of the permanent surface with granular
backfill.
(b)
Backfill in areas which are not subject to vehicular traffic
shall be accomplished by an acceptable method which will not dislodge
or damage the pipe or cause bridging action in the trench.
(c)
Only selected excavation material, free from clods or stones,
shall be used in backfilling, above the required six-inch granular
cradle.
(d)
Structure protection. Temporary supports, adequate protection
and maintenance of all underground surface structures, drains, sewers,
and other obstructions encountered in the progress of the work shall
be furnished by the contractor at his or her expense. Any structure
which may have been disturbed shall, in all cases, be restored upon
completion of the work.
(6)
Pipe laying.
(a)
Connection permits will only be issued with the understanding
that the applicant agrees to assume all responsibility and liability
for all damages to persons and property resulting from his, her or
their negligence in properly safeguarding and protecting such openings,
excavations, or work in any public street or right-of-way.
(b)
All openings made in public streets or rights-of-way shall be
protected with sufficient barriers and warning signals and a sufficient
number of warning lights shall be maintained around the excavation
at night. All other precautions shall be taken to guard the public
against accident.
(c)
The trench shall be sloped a minimum of 1/8 inch per foot, with
a slope of 1/4 inch per foot wherever practical.
(d)
The trench width at the top of the sewer pipe shall not exceed
24 inches for four-inch pipes. Trench sheetings and bracing or a trench
shield shall be used as required by the rules and regulations of OSHA.
(e)
The sanitary services pipe shall be laid upgrade from wye provided
or approved points of connection on the existing public sewer. The
sanitary service pipe shall be installed with the bell upstream, unless
otherwise approved. When pipe laying is not in progress, the upstream
end of the service pipe shall be kept tightly closed with an approved
temporary plug.
(f)
During the pipe-laying and jointing, the sanitary service shall
be kept free of any water, dirt, or objectionable matter.
(g)
Sanitary service pipes shall be laid with a minimum grade of
1/8 inch per linear foot unless otherwise directed. The contractor
shall establish such alignment and grade control as is necessary to
properly install the service.
(h)
The minimum deflection permissible at any one fitting shall
not exceed 45° (1/8 bend). The maximum deflection of any combination
of two adjacent fittings shall not exceed 45° (1/8 bend) unless
a straight pipe of not less than 2 1/2 feet in length is installed
between such adjacent fittings, or unless one of such fittings is
a wye branch with a cleanout provided on the straight leg.
(i)
All fittings shall be factory-produced and shall be designed
for installation to the public sewer connection. Fittings shall be
of the same quality and material as the pipe used for the service.
(j)
Cleanouts are to be installed at intervals of 150 feet. There
shall be at least one cleanout on each sanitary service line. If there
is not a cleanout inside the foundation, one must be provided on the
sanitary service line. Cleanouts are also required if more than one
forty-five-degree bend is used on the sanitary service line.
(7)
Road replacement.
(a)
The contractor shall restore all permanent-type pavements, sidewalks,
curbs, gutters, shrubbery, fences, poles, and other property and surface
structures removed or disturbed during, or as a result of, construction
operations, to a condition which is equal in appearance and quality
to the condition that existed before the work began. The surface of
all improvements shall be constructed of the same material and match
in appearance the surface of the improvement which was removed. Where
selected granular backfill is used, the restoration shall be made
as soon as possible after jetting of backfill has been completed.
(b)
The contractor shall carry on the work in a manner which will
cause a minimum of interruption to traffic, and may close to through-travel
not more than two consecutive blocks, including the cross street intersected.
Where traffic must cross open trenches, the contractor shall provide
suitable bridges at street intersections and driveways. The contractor
shall post suitable signs indicating that a street is closed and necessary
detour signs for the proper maintenance of traffic. Prior to closing
of any street, the contractor shall first receive the authorization
of the responsible municipal authorities.
(c)
Prior to proceeding with trench excavation, the contractor shall
contact all utility companies in the area to aid in locating their
underground services. The contractor shall proceed with caution in
the excavation and preparation of the trench so that the exact location
of underground structures may be determined. (For utility locations,
call J.U.L.I.E.; 800-892-0123.)
(d)
The contractor shall take all reasonable precautions against
damage to existing utilities. However, in the event of a break in
an existing water main, gas main, sewer, or underground cable, he
or she shall immediately notify the responsible official of the organization
operating the utility interrupted. The contractor shall lend all possible
assistance in restoring services, and shall assume all costs, charges,
or claims connected with the interruption and repair of such services
if the location of said utility was marked by the owner thereof prior
to excavation.
(8)
Separation of sanitary and water services.
(a)
Sanitary services that are laid in the vicinity of pipe lines
designated to carry potable water shall meet the following conditions:
[1]
Normal conditions. Sanitary service lines shall be located at
least 10 feet horizontally from a water service line or water main
whenever possible; the distance shall be measured from edge to edge.
[2]
Unusual condition. When local conditions prevent a horizontal
separation of 10 feet, the sanitary service may be laid closer to
the water service line, provided that:
[a]
The bottom of the water service line is at least
18 inches above the top of the sewer, and still maintains 5.5 feet
of cover over the water service line. This water service line shall
be shelved on undisturbed soil.
[b]
Where this vertical separation cannot be obtained,
the sanitary service shall be constructed of materials and with joints
that are equivalent to water main standards of construction, as noted
in this Part 1.
[Amended 5-22-2017 by Ord. No. 2017-12]
[3]
Crossing conditions. When a water service must cross a sanitary
service, it must either cross 18 inches above the sanitary service
or the sanitary service must be of water class material. The joints
of the sanitary service must be equidistant and at least 10 feet from
the point of crossing.
C.
Required plumbing.
[Added 3-24-1986 by Ord. No. 86-06]
(1)
Any building or structure having usable space below ground level
at the building site shall be equipped with an overhead plumbing system
before such building or structure is permitted to connect to the Village
sewerage system.
(2)
Any building or structure for which the ground level at the
building site is below the grade of the nearest adjacent manhole of
the Village sewerage system shall be equipped with an automatic pumping
system approved by the Village Engineer before such building or structure
is permitted to connect to the Village sewerage system.
(3)
The Water and Sewer Commissioner may waive the requirements of Subsection C(1) or (2) of this section if he or she determines in writing and after consultation with the Village Engineer that such requirements are not necessary to adequately protect the public health, safety, and welfare.
