    Requirements for bypass valves serving 1½ inches and larger water meters shall be the same as those for meter inlet valves. Bypass valves shall also be provided with a means by which the utility may attach a tamperproof seal or lock.

    (2)

    Installation. All utility work shall be performed in accordance with the "Standard Specifications for Sewer and Water Construction in Wisconsin." Such specifications are adopted and by reference made a part of this section as if fully set forth. This section incorporates any future amendments of future editions of such publications and the specifications therein shall be deemed to be in strict conformity and not contrary to or inconsistent with such specifications.

    a.

    Wherever possible, all main line valve placement should be in line with a curb or right-of-way line.

    b.

    Auxiliary valves for hydrants should be placed a minimum of three feet from the hydrant, unless otherwise specified by owner.

    c.

    Minimum cover required over a water main is six feet.

    d.

    Minimum main size is eight inches with six inches permitted for hydrant leads.

    e.

    Air release assemblies are required at high points of the water main unless a hydrant can be suitably placed.

    f.

    Mechanical joint fittings shall be used in areas where restrained joints are required.

    g.

    Hydrants shall be set on a concrete base in a truly vertical position. A drain pocket shall be provided at the base of the hydrant. Such drain pocket shall consist of two cubic yards of crushed stone or rock conforming to the requirements of ASTM C33, Gradation No. 2. The hydrant flange shall be approximately two inches above the finished grade.

    h.

    The location of the curb boxes shall be between the curb and the sidewalk or at the right-of-way line. In no case shall a curbstop be placed in a driveway.

    i.

    Curb boxes shall be extended to finished grade, shall have stationary rods extended to within 18 inches of finished grade and shall not be covered.

    j.

    The backfill for water main construction shall be gravel backfill, which conforms to the requirements of section 6.43.3 of the Standard Specifications, in trenches through all existing and proposed streets, street shoulder areas, sidewalks, curbs, driveways, parking areas and other improved (paved or graveled) areas. Under certain conditions aggregate slurry backfill may be required by the department of public works director. Excavated native material in accordance with the Standard Specifications may be used to backfill trenches throughout the remainder of the project area. Backfill shall be consolidated by mechanical compaction and/or flooding.

    k.

    Where pipe, valves and fittings installed at connections to existing mains cannot be flushed and sterilized the same as the new installations, the following procedures shall be followed:

    1.

    After the existing pipe, valve and fitting has been exposed and any plug removed, the existing ball shall be washed clean with not less than two applications of a 25 percent solution of sodium hypochlorite.

    2.

    Each new fitting, valve and section of pipe shall be thoroughly cleaned and washed to remove any and all foreign materials that could cause contamination. After cleaning and just before lowering into the trench, they shall be washed with two applications of a 25 percent solution of sodium hypochlorite. Joint material shall be sterilized before it is used. In making the installation, great care shall be used to avoid contaminating any surface that may come in contact with water when the installation is restored to service.

    l.

    The operation of existing valves and/or curbstops required in order to construct the work shall be performed by village staff only. The contractor shall be responsible for contacting the village and coordinating and scheduling any required valve and/or curbstop operations with the village or the village's authorized representative.

    m.

    A direct current (D.C.) shall be impressed on the main between fire hydrants and the voltage increased until a minimum current of 250 amperes is reached. This current shall be maintained for a period of five minutes. The voltage and amperage will be recorded for all tests. The test shall be conducted before any services are installed or hooked up.

    n.

    All valve and curbstop boxes in village rights-of-way shall be extended to grade by contractor. The contractor and/or property owner shall be responsible for maintaining all valve and curbstop boxes to grade in the rights-of-way during any construction phase in the rights-of-way, except for construction done by utility personnel.

    o.

    The copper service shall be extended into the basement a minimum one foot to 1½ feet and a maximum of three feet from the basement wall or floor. Meters larger than one inch shall be a minimum of four inches above floor elevation and securely mounted.

    p.

    No water meter shall be located in any area or enclosed in any manner that renders it inaccessible for testing, replacement or service. Each meter shall be served by a separate water service or water service branch, having its own curbstop located between the curb and the property line. Where a building has one water service serving multiple meters, the meters shall be located in a common meter room. The meter room shall be readily accessible to department personnel at all times for the purpose of testing, replacement or servicing of meters.

    q.

    No branches, takeoffs or connections shall be made ahead of the meter inlet except for the connection of multiple meters in all buildings or where parallel meters are required to provide sufficient flow rates for the building water distribution system. Where parallel meters are required, branch lengths shall be held to the minimum required for making meter connections, and each meter inlet branch shall have a permanent tag attached, indicating the unit being served.

    r.

    Separate water meters are required for lawn sprinkling systems for all nonresidential installations.

    s.

    Corporation saddles are not allowed unless authorized by the village.

    t.

    The tapping of water mains shall be witnessed and inspected by the department of public works director, building inspector or other authorized personnel. The village shall be given either oral or written notification not less than 24 hours, not including Saturday, Sunday or legal holidays, prior to tapping of mains.

    u.

    No tap larger than one inch in diameter shall be made in water mains less than 12 inches in diameter unless a stainless steel tapping sleeve, a minimum of 12 inches in length, is provided. For water services larger than one inch in diameter, multiple tappings shall be made. Multiple tappings shall be spaced not less than 18 inches center to center and shall be staggered between the upper and lower quadrants of the main in a manner that will not cause undue weakening of the main. A variance to this section may be granted by the director of public works.
