      2. All air shall be expelled from the mains as they are filled. Air valves and hydrants at high purpose.  Where permanent vents are not provided, Contractor shall install corporation cocks at high points to assure removal of air.   Such cocks shall be left in place and location noted by dimension ties on the field record set of drawings.
   3. Disinfection
      1. Sterilization of mains shall be accomplished by the use of chlorine solution fed into the main at a point of entry during the main filling operation.
   4. Requirement of Chlorination
      1. Before being placed in service, all new mains and repaired portions of, or extensions to, existing mains shall be chlorinated so that a chlorine residual of not less than 25 PPM remains in the water after 24 hours standing in the pipe.
      2. A chlorine gas-water or hypochlorite mixture shall be applied by means of a solution-feed chlorinating device.  Chlorinating devices for feeding solutions of chlorine gas must provide means of preventing the backflow or water into the chlorine cylinder.
      3. The preferred point of application of chlorinating agent is ahead of the beginning of the pipeline extension or any valve section of it and through a corporation stop inserted by the Contractor, in the tope of the pipe.  The water injector for delivering the chlorine bearing water into the pipe should be supplied from a tap on the pressure side of the gate valve controlling the flow into the pipeline extension.
      4. Water from the existing distribution system or other source of supply shall be controlled so as to flow slowly into the newly laid pipeline during the application of chlorine.  The rate of chlorine mixture flow shall be in such proportion to the rate of water entering the pipe that the chlorine dose applied to the water entering the newly laid pipe shall produce at least 25 PPM after 24 hours standing.
      5. Treated water shall be retained in the pipe long enough to destroy all nonspore-forming bacteria.  This period should be  at least 24 hours and should produce no less than 25 Ppm at the extreme end of the line at the end of the retention period.
      6. If the circumstances are such that a shorter retention period must be used, the chlorine concentration shall be increased accordingly.
      7. In the process of chlorinating newly laid pipe, all valves or other appurtenances shall be operated while the pipeline is filled with the chlorinating agent.
      8. Following chlorination, all treated water shall be thoroughly flushed from the newly laid pipeline at its extremities until the replacement water throughout its length shall, up test, be proved comparable in quality to the water served the public from the existing water supply system and approved by the Indiana Department of Environmental Management.  This satisfactory quality of water delivered by the new main should continue for a period of at least two full days as demonstrated by laboratory examination of samples taken from a tap located an installed in such way as to prevent outside contamination.
      9. Before system is placed in use, the Contractor shall obtain, from new mains two successive water samples 24 hours apart, and have them tested for bacteria content by the Indiana Department of Environmental Management.  Samples shall be drawn in accordance with the Boards procedures.  Copies of submittals  shall be provided to Engineer or Water  Operator.  The Water Operator of the Lapel Water Company shall observe all samplings.
      10. If samples do not prove satisfactory, the system shall be rechlorinated and resampled until safe water is approved.
      11. The system shall be left filled with satisfactory water before final approval by the Water Operator and the Engineer will be made.
   5. Testing the Main
      1. Under this section, the Contractor shall perform a combination pressure and leakage test on the new mains after they have been filled with water as previously specified.  This work shall be done after all of the main is backfilled.  The Water Operator of the Lapel Water Company shall observe all pressure testing.
      2. The test procedure shall be as herein specified and in accordance with applicable provision s of AWWA Standard C-600-64.
      3. The mains shall be subjected to a test pressure of 150 PSI in the reach of main being tested.  The duration of each test shall be at least one hour.  If the pressure does not decrease during the test period, then the leakage test is not required.  Each valved section of pipe shall be so tested.
      4.  A test pressure shall be developed by a pump, connections, test gauges, and all unnecessary apparatus, to be furnished by the Contractor.
      5. A leakage test under pressure shall be made after the main has been filled and if the pressure test fails.  The test shall be carried out in the following manner:
         1. Record time and line pressure (Example: 60 PSI 10:00 A.M.) (See P.W.U. - Form #P.T. 1-22-79).
         2. Pump water into new main line until pressure reaches 105 PSI, record time and reading of gauge (Example: 150 PSI - 10:05 A.M.).
         3. After pressure has reached 150 PSI, stop pumping.
         4. For an hour, remain at the site and not if any changes are made to the pressure gauges or equipment.  None should be made by anyone.  Test void if adjustments are made, with the exception of tightening fittings to prevent loss of pressure on test equipment provided.
         5. At the end of one hour, open valve to gauge and record time and pressure reading (Example:  140 PSI-11:05 A.M.)
         6. Using a pre-measured amount of water (container should measure pints and gallons),  proceed to pump line pressure back-up to 150 PSI.
         7. Record timeline pressure, and amount of water used to pump line pressure back up to 150 PSI (Example:  10:10 A.M. - 150 PSI - 1 gallon loss).
         8. Leave line alone for another hour.  
         9. At the end of the second hour, again record the time and line pressure (Example:  12:05 P.M. - 135 PSI).
         10. Using a pre-measured amount of water (container should measure pints and gallons), proceed to pump line pressure back up to 150 PSI.
         11. Record time, line pressure, and amount of water used to pump line back up to 150 PSI (Example:  12:10 P.M. - 150 PSI - 1.5 gallon loss).
         12. A line is considered satisfactory if it meets the following specifications:
             
             • Reference AWWA Spec - #C600-64
             • Leakage Test:  Apply 150 PSI # pressure for two (2) hours.
             • Allowable Leakage:
