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