[Adopted 7-14-1986 by L.L. No. 3-1986]
The Town Board of the Town of Cornwall has determined
that there is increased construction ongoing in the Town of Cornwall,
and the Town Board has determined that some of the present construction
and much of the anticipated future development of the town will involve
the installation of water mains and other water-related facilities,
and the Town Board believes that it is important for the public health,
welfare and safety of the present and future residents of the Town
of Cornwall that specifications for the installation of water mains
and water-related facilities within the Town of Cornwall, outside
of the Village of Cornwall-on-Hudson, be established, and at the request
of the Town Board the Superintendent of Public Works has presented
to the Town Board proposed specifications for the installation of
water mains and other water-related facilities which the Town Board
has found to be acceptable. Therefore, the Town Board determines that
it is in the best interests of the Town of Cornwall to enact this
article.
As used in this article, the following terms
shall have the meanings indicated:
The individual, corporation, partnership or entity installing
the water main.
The Superintendent of Public Works of the Town of Cornwall
or his duly appointed designee, including but not limited to the Engineer
for the Town of Cornwall.
The property owner owning the property and/or improvement
served by the water main or other water-related installation.
The Town of Cornwall.
The Town Board of the Town of Cornwall.
A.
The transmission line shall be American Water Works
Association Specification cement-lined with bituminous coat and bituminous
outer coat, ASA-A-21.55, Class 52, ductile iron. Joints shall be rubber
O-ring (Tyton or equal) or mechanical-joint type. Fittings shall be
Class 250 cast iron or Class 350 ductile iron, cement-lined, mechanical
joint.
B.
The pipe shall be laid directly upon the trench bottom
which has been hand trimmed to provide the pipe with a full-length
bearing, or the pipe may be supported by blocking, four blocks to
a length, and fine earth or gravel compacted under the pipe. Where
the bottom of the trench at subgrade is found to be unstable, the
contractor shall remove unstable material to the width and depth ordered
by the inspector. Before the pipe is laid, the subgrade shall be made
by refilling with gravel or crushed stone in compacted layers and
shall be thoroughly compacted so as to provide a uniform and continuous
bearing and support for the pipe. Rock shall be excavated to a depth
of six inches below subgrade and refilled with thoroughly compacted
gravel. Concrete thrust blocking shall be provided at plugs, tees,
bends and at other locations designated by the inspector.
C.
For the purpose of electrical bonding, the contractor
shall install serrated bronze wedges between the barrel and the bell
of the pipe.
D.
Pipe trenches shall be backfilled as soon as possible
after inspection. Selected well-graded material shall be used for
backfilling under, adjacent to and for a depth of one foot above the
pipe. This shall be thoroughly compacted into place mechanically.
If there is a deficiency of suitable material for backfilling, the
contractor shall furnish such suitable material from an outside source.
The remainder of the trench, to a depth of four feet above the pipe,
shall be backfilled and mechanically tamped with suitable material
from the excavation. No boulders or rock pieces larger than one cubic
foot in volume shall be used in backfilling the remainder of the trench.
If suitable material is not available from the trench excavation,
the contractor shall furnish such material from an outside source.
At the end of each day's work, the pipe shall be sealed with a suitable
pipe cap to prevent the entrance of foreign material into the pipeline.
Disinfection shall be accomplished in accordance with the methods
prescribed by AWWA Standard C-600, latest revised edition.
E.
The line shall be tested for pressure and leakage
in accordance with the method prescribed by AWWA Standard C-601, latest
revised edition.
F.
Upon the final acceptance of the work by the inspector, the contractor
shall furnish maintenance security in the sum of 10% of the cost of
the project as determined by the Town Board based upon an estimate
prepared by the inspector. The maintenance security shall be in the
form of an irrevocable letter of credit, cash or bank or certified
funds drawn on a national or state bank. The maintenance security
shall have a term of one year and shall insure the Town against the
failure of the contractor to meet the requirements of a one-year guaranty
included under this contract work.
[Amended 1-9-2017 by L.L. No.

G.
The contractor hereby guarantees all the work and
equipment furnished under this contract against any defects in workmanship
or material for a period of one year following the date of final acceptance
of work by the town. Under this guaranty, the contractor agrees to
make good, without delay, at his own expense, any failure of such
parts due to faulty materials, construction or installation or the
failure of such equipment to successfully perform all the work put
upon it within the limits of the specifications and, further, shall
make good any damage to any part of the work caused by such failure.

only and will be turned on for domestic use after the owner or his
agent has complied with all the rules and regulations of the town
and after the waterline has been accepted by the town and after a
certificate of occupancy has been issued.
(c)
Before any waterline will be accepted by the
town, a complete map showing all valves, hydrants, corporation stops,
main lines, service lines and curb boxes must be furnished the town.
This map or plan must show accurate and complete measurements acceptable
to the town.
A.
In all places where steam boilers, heating systems
or hot-water tanks are supplied with water from the water system,
the owner or consumer must see that the plumber places a suitable
safety valve, vacuum valve or other proper device to prevent damage
from collapse or explosion when water is shut off.
B.
Where the chance of a health hazard contamination
of the water supply exists through backflow or back-siphonage, an
American Water Works Association-approved reduced-pressure backflow
preventer will be installed. All of the plumbing work necessary will
be at the property owner's expense.
C.
The town shall not be liable for any damage resulting
from sudden shutting off of the supply of water from any steam boiler
or other fixture deriving its supply from the water system.
D.
The town reserves the right to limit the amount of
water furnished to any consumer should circumstances warrant such
action, or the town may entirely shut off the water supply used for
any manufacturing purpose, for furnishing power or for lawn sprinkling
at any time by giving reasonable notice by publication, if possible,
of such intended action, or in the case of making or constructing
new work or in making repairs or in an emergency, the right is reserved
to shut off the water from any consumer without notice for as long
a period as may be necessary.
E.
The town shall not be liable for any damage or loss
of any name or kind to property or persons which may arise from or
be caused by any change, diminution in or increase of the water pressure
from any cause whatever, or for the shutting off of water or water
main breaks or service leaks.
F.
Any air conditioner or cooling device using water
in its operation shall make use of a cooling tower or some means of
reusing the water.
A.
Each hydrant shall have two two-and-one-half-inch
hose connections and one four-and-one-half-inch steamer connection.
Hydrants shall have flanged ends to which can be bolted a six-inch
flanged and mechanical-joint valve or mechanical-joint end.
B.
Each hydrant shall be installed so that the hydrant
has a poured-concrete thrust block or is securely rodded to the water
main. Rods will be five-eighths-inch threaded rod minimum.
C.
Hydrants shall be set so that the bury mark is at
finished grade. In the event that extensions are needed, they will
be of proper length to bring the hydrant to normal elevation.
D.
A valve will be set so that the hydrant may be shut
off for repairs without shutting off any water main(s) or service
line(s).
E.
Where curbing is going to be used at the edge of a
roadway, the hydrant shall be set centered 24 inches from the face
of the curb.
F.
Provisions will be made at the time of installation
for the proper draining of the barrel when the hydrant is shut down.
The reduced-pressure backflow preventer shall
consist of two independently operated spring-loaded poppet-guided
check valves with an automatically operating, mechanically independent,
hydraulically dependent pressure-differential relief valve located
between the two check valves. Further, there shall be two shutoff
valves and four test cocks. If either check valve should leak, the
pressure-differential relief valve shall open and discharge to the
atmosphere, thus maintaining the zone pressure less than the supply
pressure. The device shall be constructed so it can be disassembled
and repaired without removing the main body from the supply line.
This device shall be equal in all respects to the Neptune Model 575
reduced-pressure backflow preventer as marketed by the Neptune Water
Meter Company, Atlanta, Georgia.
The double check-valve assembly shall consist
of two independently operated spring-loaded poppet-guided check valves,
each holding a minimum of one pound per square inch in the direction
of flow, two shutoff valves and four test cocks. The device shall
be constructed so that it can be disassembled and repaired without
removing the main body from the line. This unit shall be equal in
all respects to the Neptune Model 550 double check-valve assembly
as marketed by the Neptune Water Meter Company, Atlanta, Georgia.
All recipients of water service shall be deemed
to have consented to the entry of town personnel onto the premises
receiving water, which said entry shall be limited to purposes of
investigation and/or repairs to the water system.

A.
Purpose. It is the intent of this section to detail the responsibilities
of the Town and individual property owners regarding maintenance and
repair of service lines.
B.
Responsibilities of Town. The Town shall be responsible for maintenance
and repair of the curb stop, curb box and that portion of the service
line lying in the public right-of-way.
C.
Responsibilities of property owner.
(1)
The property owner shall maintain in perfect order, at his sole
cost and expense, the entire service line from the public right-of-way
to the building. Notwithstanding the foregoing, in those cases where
a curb stop exists in the public right-of-way, the property owner
shall be responsible for repairs and maintenance of that portion of
the service line between the boundary line of the public right-of-way
and the curb stop.
(2)
All leaks in that portion of the service line which the property owner must maintain and repair shall be repaired by the property owner at the property owner's sole expense. Failure to repair such leaks within 24 hours after written notice shall subject the property owner to discontinuance of water service until said repair is made. The Town shall have the right and authority to enter upon the property and make the necessary repairs and charge the cost of such repairs to the property owner. Such costs, if unpaid, shall be collected in the manner set forth in § 150-8.
(3)
In the event that a water service line freezes, the Town shall,
after notice, undertake thawing of said line. The cost of thawing
the service line shall be borne equally by the property owner and
the Town.
