L <br /> Trace wire shall run continuously along the pipeline from valve to valve or fitting. All <br /> splices shall be hot-soldered to provide continuity along the entire installation. <br /> Installation and splicing shall be in accordance with the details shown on the following <br /> insert. <br /> 4) Separation Requirements <br /> Force mains shall be laid at least ten ( 10) feet horizontally from any existing or <br /> proposed water main. Force mains crossing water mains shall be laid to provide a <br /> minimum vertical clearance of 18 inches between the outside of the water main and the <br /> outside of the force main. Where the force main passes over the water main, there shall <br /> be no joints within 10 feet of the water main. <br /> D . Field Quality Control <br /> 1 ) Hydrostatic Tests - The Contractor shall provide all necessary testing materials and <br /> shall perform all work required in connection with the test. All pipe shall be tested to a <br /> hydrostatic pressure of 100 p.s.i. for force mains and 150 p . s.i. for reuse mains . The <br /> required pressure as measured at the point of highest elevation shall be applied for not <br /> less than two hours, and all pipe, fittings, valves and joints shall be made water tight if <br /> leakage is evident. At a maximum, mains shall be tested from shut-off valve to shut-off <br /> valve. New mains shall be temporarily plugged or valved and pressure tested prior to <br /> tie-in or modification of existing pressure mains . <br /> No ductile iron pipe installations will be accepted unless and until the leakage is less <br /> than that as specified under Section 4.2 of the AWWA (ANSI) C600, P.V.C . pipe <br /> installations shall meet the leakage requirements of AWWA M23 as applicable. <br /> E. Adjusting and Cleaning <br /> 1 ) Restoring Surfaces - The top surfaces of the backfill shall be restored to the original <br /> or planned conditions . Trenches shall be carefully examined upon the completion of <br /> backfilling and surface irregularities that are dangerous or obstructive to traffic are to <br /> be removed. Paved sections shall conform in grade with adjacent areas and shall be <br /> of at least equal quality. Design mixes for flexible pavement shall be subject to <br /> approval by the Engineer. All damaged or undermined areas of existing pavement, not <br /> previously removed, shall be removed and restored to original conditions or in the <br /> specified manner. <br /> Equipment shall not travel over loose rock fragments, or other hard material, lying on <br /> sections or pavement which are not to be removed. Removal, replacement and <br /> restoration of areas of pavement shall be as indicated on drawings. <br /> F . Connection to Existing Mains <br /> The Contractor shall make no connection (open new valve) to another Contractor' s work or <br /> the Owner' s existing mains unless the work has been substantially completed, accepted, and <br /> paid for by the Owner, or expressed written permission to connect to the work has been given <br /> by the other Contractor and said written permission has been forwarded to the Engineer. <br /> END OF SECTION <br /> 02534- Sanitary Sewer Force Mains <br /> 02534 - 9 <br />
