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.
A. 
All water service lines shall be designed with a diameter necessary to provide adequate domestic or industrial and fire flow use capacity.
B. 
Water service lines servicing single family residences shall be a minimum of one-inch-diameter, Type K copper.
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.
C. 
Where a water main must cross under a sewer:
(1) 
Maintain a vertical separation of minimum 18 inches between the invert of the sewer and the crown of the water main.
(2) 
Support the sewer or drain line to prevent settling and breaking either pipe.
A. 
Comply with the requirements of water main separation.
B. 
Do not install water lines through sewer manholes.
