• <br />C-1 <br />'! <br />40 <br />Where: <br />L = allowable leakage in gallons ger hour. <br />5 = length of pipe tested, feet. <br />D = nominal diameter of the pipe in inches. <br />P = average test pressure maintained during the leakage test in pounds per square <br />inch gauge. <br />NM: Pressure testing must be completed by 12:00 noon due to thermal expansion. <br />4.2.3 The testing procedure shall include the continued application of the specified pressure to <br />the test system for the two-hour period by way of a pump taking supply from a container <br />suitable for measuring water loss. The amount of loss shall be determined by measuring <br />the volume displaced from said container. Any exposed pipe, fittings, valves, hydrants, <br />and joints shall be examined during the test. Any damaged or defective pipe fittings, <br />valves, or hydrants that are discovered following the pressure test shall be repaired or <br />replaced with sound material, and all tests shall be repeated. <br />4.2.4 The pressure shall not vary by more than ±5 psi from the required pressure for the <br />duration of the test. If at any point during the test the pressure loss exceeds 5 psi, the test <br />is considered failed. Should the test fail, necessary repairs shall be accomplished by the <br />Contractor and the test repeated until within the established limits. The Contractor shalt <br />furnish the necessary labor, water, pumps, gauges, and all other items required to <br />conduct the required water distribution system testing and perform necessary repairs. <br />DISINFECTANT PREPARATION DATA <br />Total Pounds of 65% Calcium Hypochlorite (H.T.H.) <br />Needed to Dose at 240 MOIL <br />9 <br />s <br />Size of Pipe Length of Pipe <br />(Inches) (Feet) <br />L 100 200 300 400 500 600 100 800 900 1,000 <br />2 .04 .08 .13 .17 .21 25 .29 33 .38 .42 <br />i 4 .17 .33 .50 .67 .84 1.00 1.17 .34 1.51 1.67 <br />6 .38 .75 1.13 1.51 1.88 2.26 2.64 3.01 3.39 3.77 <br />1. 8 67 1.34 2.01 2.68 3.35 4.02 4.69 5.36 6.03 6.70 <br />10 1.05 2.09 3.14 4.19 5.23 6.28 7.32 8.37 9.42 10.47 <br />t 12 1.51 3.01 4,52 6.03 7.54 9.04 10.55 1?.06 13.57 15.08 <br />p <br />16 2.68 5.36 8.04 10.72 13.40 16.08 18.76 21.44 24.12 26.80 <br />• 18 3.39 6.78 10.18 13.57 1696 20.35 23.74 27.14 30.53 33.92 <br />1 20 4.19 8.37 12.56 16.75 20.94 25.13 29.31 33.50 37.69 41.88 <br />l ,r <br />02675-5 <br />Dittnitato t At il}d+ususte Testing or <br />W ser. snd ls•s,sV*&M System <br />� [ sir,++t Uol7s rNs 1'�tat - ICcc4t+dp seri I++�nE,+:� utOtS - tlu�fecn.� Yd ftyil�:KYrc tem <br />
