A.
Except as otherwise provided herein, no residential, commercial or
industrial subdivision or development, including single lots, shall
be approved unless it is served by water piping connected to the City
water distribution system. Each subdivision or development shall include
provisions for a system complete with valves, fire hydrants, and other
appurtenances as required herein. In the case of any buildings, residential,
commercial, or industrial, constructed prior to the adoption of the
development standards and served by a private well, the following
shall apply.
B.
Any building located within the City, the property line of which
building is located within 200 feet of a water distribution line,
shall have its water piping system connected to the said water distribution
line. Any parcel and/or building owner located outside the City desiring
water service shall be required to execute a three-party agreement
between the City, Lake Township and all property owners abutting the
proposed service line prior to connecting onto the City water distribution
system, indicating any and all expenses incurred to extend said water
distribution system would be totally at the property owner's (owners')
expense.
A.
Conference. Before commencing the water distribution system layout,
the developer shall confer with the Water Superintendent or City Engineer
to determine the required size for any water distribution lines traversing
the subdivision or lot to fit the City's available capacities
of off-site downstream existing facilities with the estimated increment
of flow caused by the subdivision, proposed development and any future
off-site development. Construction required to accommodate said increments
shall be submitted as part of engineering plans. Water distribution
piping shall be extended to the far edge of the development and at
other locations indicated by the City Engineer.
B.
Location of lines. All water distribution system piping shall be
extended to the far property line and shall be constructed within
public rights-of-way or within approved easements dedicated for public
utilities.
C.
Location of curb boxes. Curb boxes shall be located in the parkway
and shall be prohibited from the area covered by a sidewalk or driveway.
All services shall extend one foot into the property and shall be
staked with a four-inch-by-four-inch post. Size specifications shall
conform to the following table:
D.
Separate single-family service required.
(1)
All attached and detached single-family dwelling units shall be served
directly by separate water piping connected to the City's water
distribution system and not to be of common service. All water service
lines shall be stubbed to the curb stop at no less than one foot inside
the property line and staked with a four-inch post not less than three
feet above grade and painted blue in color.
(2)
The water distribution system shall be designed in accordance with
the requirement of the Michigan Department of Environment, Great Lakes
and Energy (EGLE), and these development standards.
A.
Complete system required. A complete water distribution system shall
be designed to serve the entire development. The water mains shall
be of adequate size to supply the required domestic and industrial
consumption and fire flow demands throughout the system. Water main
systems shall be looped to provide continuous flow whenever possible.
Dead-end mains over 100 feet in length are prohibited unless approved
by the City Engineer. The design engineer shall submit calculations
showing flows in the system at various locations are adequate for
domestic consumption and fire flow demand with a required minimum
20 psi residual pressure.
B.
Design flows, domestic and fire protection. For purposes of water
main design, maximum daily flows shall be based on the minimum required
Fire-Flow Requirements for Buildings established by the Uniform Fire
Code, 1991 (or latest) edition, and any applicable requirements of
the Uniform Building Code.
The minimum water main pipe size shall be eight inches diameter.
A.
Installation along right-of-way. Hydrants shall be installed (type of hydrants shall be specified) at all street intersections and at a maximum spacing of 500 feet along the lengths of streets with the most remote part of any building no farther than 300 feet from a hydrant (refer to Article XX, Illustrations and References).
B.
Other requirements. When a building to be occupied will be set back
250 feet or more from a street or is located more than 300 feet from
a hydrant, additional hydrants shall be installed such that one hydrant
shall be located at the entrance to the building, and hydrants shall
be provided around the perimeter of the building at maximum 250 feet
spacing measured along access roads. Such hydrants shall be installed
not more than 120 feet nor less than 40 feet from the building. All
such hydrant shall be deeded to the City with appropriate easements
as approved by the City Engineer and City Attorney.
C.
Locations to be approved. Fire hydrant spacing plans shall be submitted
to the City Engineer for review and approval.
D.
Minimum service line to hydrants. All fire hydrants must be serviced
by a minimum of a six-inch water main.
A.
Location. Valves shall be located on water mains so as to be able
to isolate sections of main from the entire system with minimum disruption
of service.
B.
Number of valves required. Valves shall be installed so that not
over 800 feet of water main, with services, will be shut off at any
time. Valves on water mains servicing single-family residential areas
shall be installed so that no more than 800 feet of water main and/or
no more than 20 units shall be affected when shutting off a section
of main. Valves shall be installed within City right-of-way at either
end of a water main that is constructed inside rear yard easements.
C.
Valving to isolate sections of system. Valves shall be located so
that it will require no more than three valves to be closed to isolate
a section of water main.
D.
Valve boxes required. Three-piece, cast iron valve boxes are required
on all valves.
Thrust blocks shall be provided at all hydrants, tees and bends.
Where undisturbed earth is not available or not likely to be available
to support the blocks, tie rods and retaining glands shall be used
as approved by the City Engineer.
All water mains shall be constructed at a depth of five feet
from final grade to the top of the water main unless otherwise approved
by the City Engineer.
Separation and protection of water mains from sewers shall comply
with the requirements of the Michigan Department of Environment, Great
Lakes and Energy (EGLE).
A.
Wherever water mains cross storm sewers, sanitary sewer, or sewer
service connections:
(1)
Lay the water main so that its invert is at least 18 inches above
the top of the sewer.
(2)
Maintain this vertical separation for that portion of the water main
located within 10 feet horizontally of any sewer or drain crossed.
(3)
Center a length of water main pipe over the sewer to be crossed with
joints equidistant from the sewer or drain.
B.
When it is impossible to obtain the minimum 18 inches vertical separation,
or when it is necessary for the water main to pass under a sewer or
drain:
(1)
Construct the sewer or drain of pressure pipe, conforming to the
specification for water main materials.
(2)
Extend the sewer construction on each side of the crossing until
the normal distance from the water main to the sewer or drain is at
least 10 feet.
(3)
As an alternate, install either the water main or sewer inside a
water main quality casing or carrier pipe for a distance of 10 feet
measured perpendicular to the sewer on each side of the crossing.
