When installing service lines, the following specifications
and requirements must be met:
A. HDPE service lines, up to two-inch size, must be installed according
to the following specifications:
(1) All HDPE service lines shall be 200 psi rated, SDR-9, copper tube
size/poly tubing ASTM, D-2737, NSF-14, AWWA C-901.
(2) HDPE shall use compression fittings with properly sized stainless
steel sleeve insert, Mueller or Ford.
(3) The entire laying length shall be carefully inspected before placement
into the trench for cuts or gouges or kinks.
(a)
If a cut or gouge is found to be deeper than 10% of the minimum
standard wall thickness of the pipe, the entire affected length shall
be removed and discarded.
(b)
The pipe to be placed shall not be kinked, cut or gouged during
installation, or the preceding requirements shall be applied.
(c)
Pipe wall "cores" shall be retrieved from the main as part of
tapping procedure and presented to the Construction Inspector or Water
Utility representative.
B. All fittings used in copper or HDPE service lines shall:
(1) Be wrapped in a plastic baggy; and
(2) Maintain one foot on each side of the fitting.
C. Copper service shall use flared fittings. Use Teflon-based pipe dope
in making up the flare, Mueller or Ford brands acceptable.
D. Curb stop riser shall be:
(1) Minneapolis pattern 1 1/4 inch upper section brought up to finish
grade. Contractor is to supply extensions if curb stop is below finished
grade.
(2) Installed one foot on either side of the property line.
E. Curb stop shall be keyable using an eight-foot curb stop key.
The following specifications must be adhered to when tapping
a water main:
A. Stainless steel tapped repair clamp, Smith Blaire Model No. 264 or
equal, three-hundred-sixty-degree gasket coverage, shall be installed
and all bolts shall be finger-tightened for uniform gap. Apply pipe
joint lubricant (lube that is used on push-on pipe joints) to the
inside of gasket and to the pipe surface. Tighten all bolts working
from the ends to the center using torque wrenches in accordance with
manufacturer's specifications. After allowing the gasket to fully
compress for approximately 10 minutes, all bolts shall be retightened
to manufacturer's specifications, but not exceeding 150 foot-pounds
torque. Make sure the tapping device and tapping machine are fully
supported and all cutting edges sharpened. Teflon tape or Teflon pipe
dope shall be used on the corporation stop and all other pipe threads.
All bolts and nuts are to be stainless steel.
B. If tapping device is for a three-inch or larger branch line:
(1) The sleeve shall have a test port and be tested at 100 psi for five
minutes by the contractor before the actual tap proceeds; and
(2) A Water Utility representative shall witness the tapping device installation,
pressure test and tapping procedure.
C. Tapping shall take place under full system pressure with the main
full of water. No taps may be made on an inactive or nonpressurized
main. All curb stops shall be installed under full system pressure
prior to hydrostatic testing for acceptance of installation.
D. Location of all taps, tapping devices or fittings/valves for all
water pipes shall be in accordance with the following:
(1) The minimum distance from the beginning/end of the Bell or MJ of
a water pipe, fitting or another tap shall be:
(a)
For corporation tapping saddle, up to two-inch size, two feet.
(b)
For branch tapping sleeve, not less than four feet.
(2) All taps to existing and new mains shall be "live" or "wet" taps,
utilizing a tapping machine with appropriate cutting tools and sharp
cutting heads. All tap cutouts shall be given to the Construction
Inspector or Water Utility representative witnessing the tap.
E. No taps will be permitted to begin after 2:00 p.m. Additionally,
preapproval by the Water Utility is required for tapping on a Friday
or any day preceding a holiday.
F. Notice. The following notice requirements must be met:
(1) Two business days prior notice to Water Utility is required to be
given prior to installation of new taps.
(2) Two business days prior notice shall also be given to the Building
Inspector for new taps on existing mains.
Tracer wire is required to be installed atop all HDPE pipe.
When installing tracer wire, the following specifications apply:
A. A solid copper No. 10 AWG, THWN coating is required on all plastic
mains and services. Wire shall be laid parallel with and above center
line of the main, fitting and service line, and taped at maximum of
ten-foot intervals.
B. Branch or connections with the tracer wire shall require 10 full
turns of exposed and undamaged copper-to-copper contact, soldered
and watertight wrap to prevent corrosion or any deterioration of electrical
conductivity (i.e., Western Union splice).
C. Tracer wire shall be terminated outside the curb stop, with a 1.5
foot pigtail. The tracer wire shall be run from each curb stop box
and terminate at the meter or meter horn location within the building.
D. Prior to installation, tracer wire shall be tested by contractor.
The Water Utility has the option to spot-check the continuity of the
tracer wires.
The restoration phase must be completed to the following specifications:
A. Backfill of roadway shall be: No. 1 slurry, beneath any pavement,
horizontally to a maximum distance of five feet beyond the edge of
the pavement, and vertically to within four inches of the top of the
pavement; hot mix asphalt road patch, four-inch thickness; dirt restoration
with seed and mulch; and three-eighths-inch granular TB shoulder material.
Restoration shall be completed before street deposit is returned.
B. No permanent hot mix asphalt repair of asphalt pavement may be made
during the period October 1 through April 30 without permission of
the Director of Public Works/Village Engineer. Absent that permission,
a temporary asphalt pavement repair is to be made and maintained,
with permanent repair completed during the following May 1 through
May 31.
C. Contractor is responsible for notifying the Village when the restoration
is completed and ready for inspection.
