The contractor shall have each u�lity owner verify and mark the loca�ons of their respec�ve main and service lines in the field before the start of work.

18. Contractor shall be responsible to repair, at their own expense, any damage caused by construc�on.

19. In the event of damage to any opera�ng facili�es the contractor shall immediately no�fy the Using

20. The contractor shall maintain the structural integrity of all trench excava�ons, at all �mes.

21. When the depth of trench exceeds 5 FT, a trench box or shoring shall be required. If maximum trench depth exceeds 20 FT, a shoring design as per O.S.H.A. regula�ons shall be used.

22. The contractor shall, at their own expense, adequately support all u�lity poles in the area of the trench excava�on prior to excava�on.

23. The contractor shall be responsible for all fees associated with the barricading and/or closing and re-opening of any and all excava�ons during “down-�me” as required by the on-site inspectors (PADEP, Professional, Using Agency, etc…).

24. The contractor shall, at their own expense, remove and replace exis�ng guide rail, lawns, signs, sidewalks, curbs, bollards, pavement, pavement markings, etc… as needed for the comple�on of the work.

25. No addi�onal compensa�on will be made for exploratory work and/or test pits.

26. The contractor shall verify all exis�ng field condi�ons (eleva�ons, loca�on, etc…) before commencing work. The Professional shall be no�fied immediately if a conflict exists.

27. The contractor shall sawcut to full depth, all exis�ng concrete and bituminous paved areas prior to excava�on and/or removal.

28. All items coming into contact with the water being treated must be ANSI/NSF Standard 60/61 for potable water use.

29. All new waterlines crossing exis�ng sewer mains must maintain a 18” ver�cal separa�on or the sewer main shall be concrete encased, a minimum of 5 feet on both sides of the sewer main being crossed, when the water main is above the sewer line.

30. Properly grounded, tracer wire shall be installed (following manufacturers recommenda�ons) to allow for future loca�ng of waterlines.

31. All new fire hydrants throughout this project, shall be Muller Centurion Type, with integral 5" Stortz connec�on.

32. All service connec�ons to any buildings throughout this project shall be installed up to and including replacing the exis�ng curb stop with a new curb stop.

Water System Specific Notes:

1. Field Tes�ng:

• Contractor shall test completed sec�ons in conformance with AWWA standard C600. Furnish equipment and supplies and make all necessary connec�ons for the tests. The test pressure shall not be less than 150 PSI. Loss of water pressure during the test shall not exceed 5 PSI in a 2 hour period. If pressure loss exceeds 5 PSI, then the volume of water to refill the line to obtain the star�ng pressure shall be measured (This is the allowable leakage). Allowable leakage cannot exceed the standard as outlined in AWWA C600.

2. Disinfec�on and Dechlorina�on:

• Disinfec�on contractor shall disinfect pipelines in sec�ons not more than 2,000 FT long.

Disinfec�on according to AWWA C651. Use of any of the three methods described in Sec�on 5.

At least two consecu�ve samples, obtained twenty-four hours apart, from each sec�on disinfected must be cer�fied bacteriologically sa�sfactory by an independent 3rd party cer�fied water tes�ng laboratory before pipe can be placed in service. These results shall be provided to FTIG’s Environmental Office for review/approval prior to pipes being placed in service as well.

Take samples at regular intervals, not exceeding 2,000feet, throughout the length of pipeline, flush the sterilized line immediately a�er confirma�on of acceptable test results.

• Contractor shall u�lize a dechlorina�on device to assure less than 1 PPM chlorine is being discharged from system a�er tes�ng. The Arden Bazooka hydrant connec�ng dechlorina�on device or approved equal device or method is preferred.

3. Swab pipe and fi�ngs that will not be pressure tested or chlorinated with chlorine solu�on during installa�on and use extra precau�on to prevent soil and debris from entering pipe. Incorporate untested pipe into the flushing rou�ne when possible. When connec�ng new pipe to the exis�ng water system, use opera�ng pressure to visually inspect for leaks. When feasible preform inspec�on prior to backfilling. Comply with all standards and requirements of PADEP/AWWA.

4. Contractor shall install supplemental joint restraints in lieu of thrust block for all pipe deflec�on for crossings, etc.

• Based on 150 PSI pressure and 20-foot pipe lengths the following number of upstream and downstream joints require restraints:

Bends 11 ¼ and 22 ½ degree – none required.

45 degree – 1 required.

90 degree – 2 required.

• Pipe step reduc�on (Step 1 (8x6) Step 2 (8x4) Step 3 (8x3)).

Step 1 – 1 required.

Step 2 – 2 required.

Step 3 – 3 required.

• Standard tee fi�ng – requires minimum 1 on branch side direc�on.

• All ver�cal offsets beyond allowable deflec�on. All joints must be restrained between offsets and 1 joint immediately prior and a�er.

5. The contractor must provide thrust restraints in accordance with detail provided. The contractor must furnish and install mechanical joint thrust restraint glands at all fi�ngs and mechanical joints.

6. Water main and fi�ngs loca�ons shown on the drawings for the new water mains and appurtenances may be changed due to field condi�ons.

7. Fi�ngs and their loca�ons indicated on the drawings are tenta�ve. The contractor must complete the installa�on with the necessary fi�ngs dictated by field condi�ons. No addi�onal payment will be made for devia�ons from the indicated fi�ngs.

U�lity Coordina�on Notes:

1. Contractor shall enter a PA One Call complex project one call no�fica�on �cket and schedule a u�lity coordina�on mee�ng with all u�lity owners prior to the start of any construc�on work on-site.

2. Most facili�es on FTIG are services by natural gas and therefore have services to buildings and mains that will be encountered and crossed throughout the project area.
