    anchored to prevent floating.

F.  Trenching and Backfill

```{=html}
<!-- -->
```
1.  Trench Type 4: Unless otherwise shown on the drawings the trench for
    pipe installation shall be Type 4 as defined by AWWA C600. Pipe
    bedded in 4\" of sand, gravel, or crushed stone. Maximum size of
    pipe bedding material shall not exceed 1/2\" particle size and
    material shall be uniformly-graded, Backfill compacted to top of
    pipe to 80 percent.

2.  Ductile Iron Pipe (DIP): The trench width from the bottom of pipe to
    12\" above top of pipe shall not exceed the outside diameter plus
    24\". The pipe haunch shall be backfilled so no voids exist and than
    backfilled in 8\" maximum lifts. Unless otherwise specified,
    continue 8\" lifts and 90 percent compaction in areas under roadways
    and paving. Compact to normal soil density in areas not supporting
    roadways or paving unless noted otherwise.

    existing PVC pipe is extremely important. Only hand tampers shall be
    used to compact backfill around the pipe. Care shall be taken not to
    damage or misalign the pipe during compaction. The trench width from
    the bottom of pipe to 12\" above top of pipe shall not exceed the
    outside diameter plus 24\". If trench width exceeds the maximum
    allowed or PVC pipe is placed in compacted backfill than the pipe
    embedment shall be compacted to 2.5 diameters on each side of the
    pipe. The pipe haunch shall be backfilled so no voids exist and than
    backfilled in 8\" maximum lifts compacted to 90 percent density to
    the centerline of pipe. Unless otherwise specified continue 8\"
    lifts and 90 percent compaction in areas under roadways and paving.
    Compact to normal soil density in areas not supporting roadways or
    paving unless noted otherwise.

4.  Minimum depth of cover for water lines shall be 3 feet from the top
    of pipe to finished grade. Unless otherwise indicated on the
    contract drawings.

5.  When it is necessary to deflect ductile iron pipe for changes in
    horizontal or vertical alignment, the amount of deflection shall not
    exceed 2/3 of the manufacturer\'s recommended maximum deflection. A
    fitting or several shorter lengths of pipe shall be used when
    necessary. PVC pipe shall not be deflected at the joints.

    A.  Joints

```{=html}
<!-- -->
```
1.  Push-on-Joints: Immediately prior to making the joint, the rubber
    gasket shall be removed and cleaned, the groove cleaned, the gasket
    replaced, and the bell and spigot ends thoroughly cleaned and
    lubricated with a suitable sterile soft vegetable soap compound.
    Field-cut plastic pipe sections shall be beveled for joining as
    recommended by the pipe manufacturer.

2.  Mechanical Joints: The socket and plain ends shall be thoroughly
    cleaned immediately prior to making the joint. Wash the seating
    surfaces and the rubber gasket with a soapy solution. Seat the plain
    end fully in the socket before slipping the gasket into the socket.
    The joint shall be kept straight during assembly. If a joint
    deflection is required, make the deflection after assembly, but
    before tightening bolts, tighten nuts 180 degrees apart in pairs.
    Alternate pairs until all nuts are within the manufacturer\'s
    recommended range of torque. The Contractor shall have a torque
    wrench on hand at the work site so that the Sandia National
    Laboratories (SNL) Inspector may verify tightening torque on any
    joint.

3.  Flanged Joints: Clean the flanged ends to be joined immediately
    prior to joining. Only one gasket shall be permitted in a flange
    joint. Nuts shall be tightened similar to mechanical joints to
    within the torque range recommended by the pipe manufacturer.

    with bituminous material prior to backfilling. Additionally, all
    other hardware shall be fully coated with an asphalt or plastic
    varnish prior to backfilling.

    1.  []{#__RefHeading___Toc151458509 .anchor}Location Of Water And
        Sewer Lines

        A.  Mains: Water and sewer mains running parallel shall be laid
            at least 10 feet apart horizontally, with the water main at
            a higher elevation than the top of the sewer line. Water and
            sewer mains shall be laid in separate trenches in all cases.
            Where water and sewer mains are laid closer than 10 feet or
            where they are crossing, the bottom of the water main shall
            be at least 12\" higher than the top of the sewer line,
            otherwise, the sewer line shall be of pressure class pipe,
            or shall be encased in concrete, within 10 feet either side
            of the water main.

        ```{=html}
        <!-- -->
        ```
        A.  Service Lines: Water and sewer service lines shall not be
            laid in the same trench, unless the bottom of the water
            line, at all points, is at least 12\" above the top of the
            sewer line, and the water line shall be laid on a solid
            shelf excavated at one side of the common trench. Where
            water and sewer service lines cross, the water line shall be
            at least 12\" higher than the sewer.

    2.  []{#__RefHeading___Toc151458510 .anchor}Thrust Restraint

        All thrust restraint shall be accomplished by mechanical means
        unless shown otherwise on the contract drawings. Provide
        mechanical joint restraints at all tees, plugs, caps, bends,
        reducers, valves, and other mechanical joint fittings. Concrete
        blocking shown at a point of connection to an existing does
        eliminate the requirement for restrained joints at the fitting
        in question unless specifically stated in the contract drawings.
        Restrained joints will be subject to the hydrostatic test
        pressure as specified under hydrostatic testing. Restrained
        lengths shall be in accordance with the contract documents or
        applicable SNL Standard Drawings.

        A.  Mechanical joint restraints shall be installed as shown in
            the contract drawings and per AWWA C600. The use of
            mechanical joint restraints for modifications to existing
            piping shall not constitute proper thrust restraint unless
            verification is made that the uncovered adjacent joints are
            properly restrained. Concrete blocking may be used in
            addition to required mechanical joint restraints as
            alternative to verification of existing joints. Prior to
            pressure testing the pipe must be properly restrained
            against movement, backfilled, and compacted between joints
            to prevent separation of the joints.

        ```{=html}
        <!-- -->
        ```
        A.  Concrete blocking shall be installed in accordance to the
            requirements of Section 03300, \"Cast-in-Place Concrete\".
            Blocks shall be placed in the general shape and to the
            minimum dimensions indicated on the standard drawings, and
            shall be placed between the fitting and the undisturbed wall
            of the trench. Concrete shall be placed so that it does not
            make contact with any bolts or nuts on the fittings. A
            polyethylene film shall be placed between the fitting or
            valve and the thrust block. Pipe shall not be flushed,
            pressurized, or otherwise disturbed, until the new concrete
            blocking has reached its initial set and developed adequate
            strength. Prior to pressure testing the pipe must be
            properly restrained against movement, backfilled, and
            compacted between joints. All hardware shall be fully coated
            with asphalt or plastic varnish.

        B.  Installation of Mechanical Joints per AWWA C600

```{=html}
<!-- -->
```
1.  Clean the socket and plain end. Lubrication and additional cleaning
    should be provided by brushing both the gasket and plain end with
    soapy water or an approved pipe lubricant meeting the requirements
    of ANSI/AWWA C111/A21.11, just prior to slipping the gasket onto the
    plain end for joint assembly. Place the gland on the plain end with
    the lip extension toward the plain end, followed by the gasket with
    the narrow edge of the gasket toward the plain end.

2.  Insert the pipe into the socket and press the gasket firmly into the
    gasket recess. Keep the joint straight during assembly.

3.  Push the gland toward the socket and center it around the pipe with
    the lip against the gasket. Insert bolts and hand tighten nuts. Make
    deflection after joint assembly but before tightening.

4.  Tighten the bolts to the normal range of bolt torque as indicated in
    the table below while at all times maintaining approximately the
    same distance between the gland and the face of the flange at all
    points around the socket. This can be accomplished by partially
    tightening the bottom bolt first, then the top bolt, next the bolts
    at either side, finally the remaining bolts. Repeat the process
    until all bolts are within the appropriate range of torque.

        Flushing shall be performed in accordance with SNL Specification
        02516 Flushing and Disinfection.

    2.  []{#__RefHeading___Toc151458522 .anchor}Hydrostatic Testing

        A.  WARNING: The testing methods described in this section are
            specifically for water pressure testing. These procedures
            are not permitted for air pressure testing due to the
            serious safety hazards involved.

        ```{=html}
        <!-- -->
        ```
        A.  New water line installations shall be hydrostatically tested
            in accordance with AWWA C600 for ductile-iron pipe. The SDR
            shall be present at all times for the duration of the test.

        B.  All temporary plugs, taps, thrust restraints, gauges, and
            other necessary testing equipment must meet the same
            nationally recognized standards as listed in Part 2 -
            Products. They shall be provided by the Contractor and shall
            be subject to approval by SNL, except that SNL may elect to
            provide the gauges used in the test.

        C.  New lines shall be tested without being connected to
            existing lines.

        D.  Hydrostatic test pressure for new lines (excluding the
            section of fire protection line which runs from the Post
            Indicator Valve (PIV) to the sprinkler riser), shall be 150
            psi or 1.5 times the normal working pressure of the line,
            whichever is greater. In addition, test pressure for new
            fire lines, as defined above, shall be a minimum of 200 psi
            or 50 psi in excess of static pressures greater than 150
            psi, per NFPA 24. Before applying the specified test
            pressure, air shall be expelled completely from the pipe,
            valves, and hydrants. If permanent air vents are not located
            at all high points, the contractor shall install corporation
            cocks at such points so that the air can be expelled as the
            line is filled with water. After all the air has been
            expelled, the corporation cocks shall be closed and the test
            pressure applied. At the conclusion of the pressure test,
            the corporation cocks shall be removed and plugged or left
            in place at the discretion of the SDR. Test duration shall
            be not less than 2 hours. During the test, the test pressure
            shall not drop for lines less than 1000 feet long. For lines
            greater than 1000 feet long, see article 3.14 F. Each
            section of the new line between valves shall be tested
            individually to demonstrate that each valve will hold the
            test pressure. In cases where a new main is being connected
            to an existing main without the installation of a new valve,
            the end of the new main shall be temporarily capped and
            restrained, and the test shall be performed on the new line.
            Tests shall not be made with an existing main included in
            the test section.

        E.  The allowable leakage rate for lines greater than 1000 feet
            long shall be 11.65 gpd, per mile, per inch nominal diameter
            while maintaining the test pressure. The new waterline may
            be accepted if the total test leakage is less than the
            calculated allowable leakage. If the actual leakage is
            greater than the allowable leakage, the Contractor shall
            locate the leakage and make repairs as necessary at no
            additional cost to SNL. The Contractor shall repeat the test
            until the leakage is within the specified allowance. All
            visible leaks, regardless of the amount of leakage, shall be
            repaired.

        F.  The Contractor shall submit a calculation and the data sheet
            to SNL for each test, showing all data and measured
            quantities, including the actual leakage, the location of
            each test section, and a calculation of the allowable
            leakage for the test section. The test sheet shall be signed
            and dated by the Contractor\'s representative. For dedicated
            Fire Protection lines, complete and submit a Contractor\'s
            Material and Test Certificate for Underground Piping in
            accordance with the current NFPA 24.

    3.  []{#__RefHeading___Toc151458523 .anchor}Disinfecting

        Disinfection of the water system shall be performed in
        accordance with SNL Construction Standard Specification 02516,
        Flushing and Disinfection of Underground Water Lines for
        Domestic and Fire Protection Systems.

    4.  []{#__RefHeading___Toc151458524 .anchor}Storage

        A.  All plastic pipe shall be protected from sunlight for
            long-term storage. Any plastic pipe showing discoloration
            shall be rejected.
