<br />CHLORINE IN THE WATER LEAVING THE MAIN THAN IN THE WATER ENTERING THE MAIN.
<br />THE CONTRACTOR SHALL COLLECT A SAMPLE FOR BACTERIOLOGICAL EXAMINATION IN A STERILE BOTTLE PROVIDED BY
<br />THE LABORATORY. ON THE LABEL, GIVE DATE, ADDRESS, AND THE NAME OR NUMBER FOR THE PROJECT. WHERE
<br />POSSIBLE THE SAMPLE SHOULD BE TAKEN FROM A SERVICE LOCATED NEAR THE END OF THE CHLORINATION SECTION,
<br />OTHERWISE, IT MAY BE TAKEN THROUGH THE SAME BLOWOFF USED FOR FLUSHING THE HEAVILY CHLORINATED WATER
<br />OUT OF THE MAIN SO THAT THE BLOWOFF IS STERILIZED.
<br />IF THE BACTERIOLOGICAL TESTS ARE UNSATISFACTORY, THE MAIN SHALL BE RESTERILZED USING METHOD NO. 2, AND
<br />THE STERILIZATION REPEATED, IF NECESSARY, UNTIL SATISFACTORY RESULTS ARE OBTAINED.
<br />1. METHOD NO. 1 - H.T.H. TABLET METHOD, THIS METHOD IS PREFERRED FOR SHORT JOBS AND FOR SMALL
<br />DIAMETER PIPE OF ANY KIND. IT CANNOT BE USED WHERE TRENCH WATER HAS ENTERED THE MAIN. THE MAIN CANNOT
<br />BE FLUSHED PRIOR TO STERILIZATION, SO THE METHOD REQUIRES THAT THE PIPE BE KEPT CLEAN DURING INSTALLATION.
<br />USING PERMATEX NO. 1 AS AN ADHESIVE, FASTEN THE REQUIRED NUMBER OF TABLETS (SEE TABLE 1) TO THE INSIDE
<br />TOP OF EACH LENGTH OF PIPE. THE TABLETS MAY BE FASTENED TO THE PIPE BEFORE IT IS PLACED IN THE TRENCH
<br />PROVIDING THE TOP OF THE PIPE IS MARKED TO ENSURE THAT THE TABLETS ARE ON THE TOP OF THE PIPE AFTER
<br />INSTALLATION.
<br />WHEN USING DRESSER OR SIMILAR COUPLINGS, AN ADDITIONAL TABLET SHALL. BE CRUSHED AND PLACED IN THE
<br />ANNULAR SPACE BETWEEN THE COUPLING AND THE PIPE. FILL THE PIPE VERY SLOWLY AND PROCEED AS OUTLINED
<br />UNDER GENERAL INSTRUCTIONS OF THE MANUFACTURER.
<br />METHOD N0. 2 - H.T.H. SOLUTION WITH HAND PUMP METHOD, THIS METHOD IS GENERAL IN SCOPE AND MUST BE USED
<br />WHEN IT IS NECESSARY TO RECHLORINATE AN EXISTING MAIN. WHEN THIS METHOD IS USED ON A MAIN COUPLED WITH
<br />DRESSER OR SIMILAR COUPLINGS, A PINCH OF H.T.H. POWDER SHALL BE PLACED IN EACH COUPLING AS THE MAIN IS
<br />LAID. EQUIPMENT REQUIRED INCLUDES AN ORDINARY HAND TEST PUMP, SOLUTION HOSE, AND A FIVE (5) GALLON CAN
<br />TO CONTAIN THE CHLORINE SOLUTION.
<br />A COMPACT AND CONVENIENT ASSEMBLY CAN BE MADE BY MOUNTING THE SOLUTION CAN AND THE PUMP ON A
<br />SUITABLE BOARD WITH A PIPE CONNECTION FROM THE TANK ON THE SUCTION SIDE OF THE PUMP.
<br />No.I DESCRIPTION
<br />H.T.H. COMES AS A POWDER WHICH MUST BE DISSOLVED IN WATER. STRONG CHLORINE SOLUTIONS SHOULD BE
<br />HANDLED WITH CARE ACCORDING TO MANUFACTURER'S INSTRUCTIONS.
<br />MAKE UP CHLORINE SOLUTION ACCORDING TO TABLE II. THE QUANTITY REQUIRED IS ESTIMATED FROM TABLE II. AN
<br />EXCESS VOLUME SHOULD BE PREPARED SO AS NOT TO EMPTY THE CONTAINER BEFORE THE JOB IS COMPLETE.
<br />CONNECT PUMP TO MAIN. USE A CORPORATION COCK FOR THIS PURPOSE AND MAKE CONNECTION AT OR AHEAD OF
<br />THE INLET END OF THE NEW LINE.
<br />AFTER FINISHING APPLICATION OF CHLORINE, CLOSE VALVE OR BLOWOFF. DISCONNECT AND FLUSH PUMP THOROUGHLY
<br />WITH FRESH WATER.
<br />IF THE ABOVE PROCEDURE HAS TO BE VARIED BECAUSE OF SOME UNUSUAL CONDITION, IT WILL BE NECESSARY ONLY
<br />TO REGULATE THE PUMP, CONTROL THE WATER FLOW, OR ADJUST THE STRENGTH OF THE CHLORINE SOLUTION TO GIVE
<br />A DOSE OF AT LEAST FIFTY (50) PPM.

<br />TABLE III IS THIRTY-FIVE (35) MINUTES, 11-2/3 GALLONS WILL BE REQUIRED; AND IF THE DISCHARGE RATE IS FIFTY
<br />(50) GPM, THE SOLUTION SHOULD CONTAIN ONE (1) POUND OF H.T.H. IN FIVE (5) GALLONS. PREPARE FIFTEEN (15)
<br />GALLONS OF SOLUTION SO AS TO BE SURE OF HAVING AN ADEQUATE AMOUNT.
<br />OPERATE THE HAND PUMP AT A RATE OF FIVE (5) GALLONS IN FIFTEEN (15) MINUTES, OR ONE (1) GALLON IN THREE
<br />(3) MINUTES.

<br />THE ABOVE TABLE IS USED TO ESTIMATE THE TIME REQUIRED TO APPLY CHLORINE. FOR EXAMPLE: SEVEN HUNDRED
<br />FEET (700') OF EIGHT INCH (8") MAIN CAN BE FILLED WITH CHLORINE SOLUTION IN THIRTY-FIVE (35) MINUTES WITH A
<br />DISCHARGE RATE OF FIFTY (50) GPM.
<br />REDUCED PRESSURE BACKFLOW PREVENTER--THE REDUCED PRESSURE BACKFLOW PREVENTER SHALL BE A COMPLETE
<br />ASSEMBLY, CONSISTING OF TWO (2) SEPARATE SPRING LOADED CHECK VALVES AND A DIFFERENTIAL RELIEF VALVE.
<br />THESE DEVICES SHALL AUTOMATICALLY REDUCE THE PRESSURE IN THE "ZONE' BETWEEN THE CHECK VALVES.
<br />BOTH CHECK VALVES AND THE DIFFERENTIAL RELIEF VALVE SHALL BE CONSTRUCTED SO THAT THEY MAY BE SERVICED
<br />WITHOUT REMOVING THE DEVICE FROM THE LINE. THE DEVICES SHALL BE RATED TO 175.0 PSI WORKING PRESSURE.
<br />THE REDUCED PRESSURE BACKFLOW PREVENTER SHALL BE AWWA OR USC APPROVED AND SHALL BE INSTALLED SO
<br />THAT FLOODING WOULD NOT CAUSE THE RELIEF VALVE TO BECOME SUBMERGED. IT SHALL BE INSTALLED A MINIMUM OF
<br />TWELVE INCHES (12") ABOVE GRADE.
