<br />of drawing CW 850. Tracer wire splices using appropriate connectors are required at
<br />all locations where the wire is cut and at all plastic service lines.
<br />after a minimum of 6 inches of sand backfill has been placed over the pipe. Flooding,
<br />jetting or puddling may be employed for compaction in the first lift although great care
<br />must be taken to prevent drainage or flotation of the pipeline. Apply only enough
<br />water to give complete saturation. Erosion of support at the pipe sides and bottom by
<br />water jetting must be prevented. Placing rocks or hard lumps in the embedment
<br />backfill or final backfill 's strictly prohibited.
<br />FINAL BACKFILL: In areas wt.me required, the permanent pavement and temporary

<br />I SPECIFICATIONS FOR DISINFECTION I
<br />OF NEW MAINS
<br />NOTE: The disposal of NI chlorinated water generated from the procedures in the
<br />"SPECIFICATIONS FOR DISINFECTION OF NEW MAINS" shall be the Contractor's
<br />responsibility. The Contractor shall meet all local agency's requirements and dispose
<br />of all chlorinated water in a safe and lawful manner.
<br />r h i discharged
<br />If dechlorination of the water is required, then the chlorinated wale that a g
<br />to an open stream or storm drain shall be dechlorinated by water Industry accepted
<br />methods. The dechlorinated water will be tested for chlorine residual to verify that no
<br />detectable amount of free chlorine is present. This testing will take place from the
<br />onset of discharging the water and at frequent Intervals throughout the dewatering of
<br />the pipe.
<br />GENERAL INSTRUCTIOAS
<br />1. Precautions shall be taken to prevent soiling of pipe, fittings and other materials.
<br />Pipe and fittings sha,l be stored so as not to accumulate mud or water, and other
<br />material shall be stored In a clean, dry location. Particular care shall be taken to keep
<br />rubber gaskets and pipe ends clean.
<br />2. All pipe shall be clean before lowering the pipe Into the trench.
<br />3. When the mein is left unattended, even for a short time, the ends shall be plugged
<br />to prevent the entrance of foreign material or small animals.
<br />4. Apply chlorine, using one of the methods described under "Chlorine Application
<br />Methods".
<br />5. Isolate the main by closing valves and allow heavily chlorinated water to stand
<br />therein for a contact period of at least twenty-four hours.
<br />6. At the and of the contact period, flush the main thoroughly. The test for chlorine
<br />should show no more chlorine in the water leaving the main than In the water
<br />entering the main.
<br />7. The Company's representative will collect a sample for bacteriological examination
<br />and send it to the laboratory. The sample should be taken from a service located near
<br />the end of the chlorinated section or from the sampling device illustrated in drawing
<br />CW 638.
<br />8. If bacteriological tests are positive, the action to take will be noted on the
<br />laboratory report. Prompt attention to these orders is essential.
<br />CHLORINE APPLICATION METHODS
<br />METHOD NO. 1 - H.T.H. TABLET METHOD' This method is preferred for short jobs
<br />and for small diameter pipe of any kind. It cannot be used where trench water has
<br />entered the main. Th . main cannot be flushed prior to disinfection, so the method
<br />requires that the pipe to kept clean during laying.
<br />Using Permatex No. 1 as an adhesive, fasten the required number of tablets (see
<br />Table II) to the top of each length of pipe. Tubes of Permatex may be purchased
<br />locally at any auto parts store. The tablets may be fastened to the pipe before it is
<br />placed in the trench provided the top of the pipe is marked to avoid the possibility that
<br />the pipe may be rotated.

<br />method is general in scope and must be used when it is necessary to re -chlorinate an
<br />existing main. It may also be used on new mains, In which case place 10 ounces of
<br />• •
<br />H.T.H. granules at the upstream end of the first length of pipe Into which water will
