All water main shall be installed with approved joint restraint clamps, rods, and devices as approved by the Engineer at each fitting. The following table shows the minimum length of pipe to be restrained: 45 Bend 22 -1/2 Bend 5 Dead End L.F. Tee Branch Pipe Diameter or 90 Bend 6 23 L.F. 8" 23 L.F. 10" 38 L.F. 12" 45 L.F. 16" 60 L.F. 45 Bend 22 -1/2 Bend 5 L.F. O L.F. 7 L.F. 0 L.F. 10 L.F. 0 L.F. 14 L.F. 0 L.F. 22 L.F. 10 L.F. B. The cost of providing joint restraining shall be considered as incidental to the cost of the watermain installation. If the above joint restraint protection cannot be fully obtained due to the design or field alignment, concrete thrust blocking shall also be provided where specified by the Engineer. C. Where restrained joints are required and the pipe is in a casing near the fitting to be restrained, the length of pipe in the casing shall not be included in the length of pipe necessary to develop sufficient soil friction to overcome thrust. D. All hydrants, valves, services, stubs and extensions, blind flanges, plugs, and all things retaining water pressures must be tied with tie rods as a pressure restraint. All tie rods or bare metals shall be coated with bitumastic or approved equal. 3.02 HYDROSTATIC PRESSURE TEST: A. Before a new water main can be filled for testing or flushing, a 11 24" hour notice must be given to the City Water Department. A permit may be issued for this purpose when Water Department personnel are not available for valve operation, but only after a "24" hour notice has been given. B. If it becomes necessary to interrupt water service because of new utility construction, sufficient notice must be given to the City Water Department so that written notice may be given to the affected customers 11 24 " hours prior to interruption of service. When notified, the City Water Department will take the responsibility for customer notification. C. If a Contractor, acting on his own, operates a fire hydrant or water main valve without a valid permit in his possession, the City Water Department and the Public Safety Department will seek the maximum allowable penalty because of the potential for jeopardizing the public's safety and health. D. After the pipe has been laid including fittings, services, valves and hydrants, and the line has been backfilled in accordance with these Specifications, all newly laid pipe, or any valved section thereof, shall be subjected to a hydrostatic pressure test. E. Each valved section of pipe shall be slowly filled with water. The specified test pressure, measured at the lowest point of elevation, shall be applied by means of a pump connected to the pipe in a satisfactory manner. The pump, pipe connection, gauges and all necessary apparatus shall be furnished by the Contractor. Before applying the specified test pressure, all air shall be expelled from the pipe. To accomplish this, taps shall be made if necessary at points of highest elevation and afterward tightly plugged. F. The test pressure shall be brought to 150 psi. Thereafter, the test shall be considered satisfactory if witho additional water the pressure remains constant for a period of two (2) hours at any specific pressure between 125 psi and 150 psi. G. Any cracked or defective pipes, fittings, valves or hydrants discovered in consequence of the pressure test shall be removed and replaced by the Contractor and the test shall be repeated until satisfactory to the Engineer. 3.03 ELECTRICAL CONDUCTIVITY TEST: A. After the hydrostatic test has been completed, a conductivity test shall be conducted in accordance with the following specification: 1. TEST PROCEDURE: a. - The system (pipeline and hydrants) shall be tested for electrical continuity and current capacity. The electrical test shall be made after the hydrostatic pressure test. Backfilling shall have been completed. The line may be tested in sections of convenient length as approved by the Engineer. b. Direct current of 350 amperes, + or - 108, shall be passed through the pipe line for 5 minutes. Current flow through the pipe shall be measured continuously on a suitable ammeter and shall remain steady without interruption or excessive fluctuation throughout the 5 minute test period. C. Insufficient current or intermittent current or arcing, indicated by large fluctuation of the ammeter needle, shall be evidence of defective electrical contact in the pipe line. The cause shall be isolated and corrected. Thereafter, the section in which the defective test occurred shall be retested as a unit and shall meet the requirements. 2. NOTES ON TEST PROCEDURE: a. Sources of D.C. current for these tests may be motor generators, batteries, arc welding machines, etc.; D.C. arc welding machines will probably be the usual source. These machines are available in adequate capacity for these tests and are equipped with controls for regulating the current output. b. Cables from the power source to the section of the system under test should be of sufficient size to carry the test current without overheating or excessive voltage drop. Usable sizes will probably be in the range of 2/0 to 4/0 A.W.G. C. Connections for the test shall be made at hydrants. The hydrants shall be in the open position with the caps on during the test. The cable shall be clamped to the top operating nut. Note: After the test, the hydrant shall be shut off and a cap loosened to allow hydrant drainage. Tighten cap after drainage. d. ' A hook -on type D.C. ammeter placed on one of the cables leading to the hydrant is a convenient method of measuring current. e. In using arc welding machines, the current control should be set at a minimum before starting. After starting the machine, advance the control until the current indicated on the ammeter is at the desired test value. Caution: In case of open circuits at joints or connections, the voltage across the defective joint or connection will be in the order of 50 - 100 volts. } 3.04 DISINFECTION OF WATER MAINS: A. GENERAL 1. All pipelines installed shall be disinfected with a strong chlorine solution. Disinfecting may be done concurrently with pressure and leakage testing or after pressure and leakage testing at the option of the Contractor. Each section line that is repaired shall be disinfected after such repairs are made. All necessary disinfection equipment and materials shall be provided by the Contractor. B. FLUSHING 1. The pipeline shall be flushed at a velocity of at least 2.5 feet per second immediately prior to disinfection. A 24 hour notice is required to the City Water Department for pipeline flushing. A 1. Disinfection shall be performed using either chlorine gas or calcium hypochlorite solution. Chlorine gas shall conform to AWWA B301 and shall be handled under pressure as an aqueous solution. Calcium hypochlorite shall conform to AWWA B300 and shall be granules with 70 per cent available chlorine. D. FEEDING 1. Chlorine gas shall be used only as a solution. Introduction of chlorine gas into the pipeline directly will not be permitted. when chlorine is used, a chlorinator and booster pump with injector shall be provided. 2. Calcium hypochlorite shall be made into a solution and pumped into the pipeline with a suitable chemical feed pump. APPLICATION 1. Pipelines shall be disinfected by either the continuous feed method or the slug method. 2. In using the continuous feed method, chlorine feed shall be proportional to the rate of flow into the pipe so that the entering water contains at least 50 mg /1 of available chlorine. Chlorine application shall be continuous until the entire pipeline is filled with the chlorine solution. The treated water shall be retained in the pipeline for at least 24 hours and the chlorine residual at the end of the period shall be at least 25 mg /1. 3. In using the slug method, chlorine shall be fed at a rate that will produce at least 300 mg /1 in the water entering the pipeline and a sufficient quantity of water shall be chlorinated so that all parts of the pipeline will be exposed to chlorine concentration of 300 mg /1 for at least 3 hours. 4. During disinfection all valves and hydrants shall be operated to insure that all appurtenances are disinfected. F. BACTERIOLOGICAL TESTS 1. The chlorine solution shall be flushed out of the line and samples shall be collected and tested for bacteriological quality after the line has set for a minimum of 24 hours. The samples shall be collected by the Contractor's personnel and the cost of these tests paid for by the Contractor. A 24 hour notice is required to the City Water Department for pipeline flushing. G. REPEAT TESTING 1. If initial disinfection fails to produce satisfactory bacteriological samples, the disinfection shall be repeated until satisfactory bacteriological samples are obtained. Costs for additional disinfection shall be borne by the Contractor. H. INSPECTION 1. The above operation shall be supervised by a qualified Inspector furnished by the Consultant. 3.05 WATER MAINS CROSSING SEWERS A. Water mains crossing sanitary sewers or storm sewers shall be laid to provide a separation of at least 18 inches between the bottom of the water main and the top of the sewer. When local conditions prevent a vertical separation as described, the following shall be used: 1. Sewers passing over or under water main shall be constructed of materials equal to water main standards of construction. 2. water mains passing under sewers shall, in addition, be protected by providing: a. a vertical separation of at least 18 inches between the bottom of the sewer and the top of the water main. b. adequate structural support for the sewers to prevent excessive deflection of joints and settling on and breaking the water mains. C. that the length of water pipe be centered at the point of crossing so that the joints will be equidistant and as far as possible from the sewer. S. pater mains shall be laid at least 10 feet horizontally from any sanitary sewer, storm sewer or sewer manhole whenever possible. When local conditions prevent a horizontal separation of 10 feet, a watermain may be laid closer to a storm or sanitary sewer provided that: 1. The bottom of the main is at least 18 inches above the top of the sewer. e. Where this vertical separation cannot be obtained, the sewer shall be constructed of materials and with joints that are equivalent to water main standards of construction and shall be pressure tested to assure water tightness prior to backfilling.
