Section 509 of the public health code is amended to read as follows:
"Section 509. PIPELINE TREATMENT. Every new water main and every repaired section of an existing water main must be cleared of coliform bacteria by the proper application of chlorine in sufficient quantities to give a minimum of fifty (50) parts per million of available chlorine. The new or repaired pipe shall be thoroughly flushed before and after chlorination. If the first application of chlorine is not sufficient, the procedure shall be repeated until the water will meet the standards set forth in the United States Public Health Service Drinking Water Standards. Means or methods providing equivalent treatment may be used if approved by the Health Officer."
(Prior code § 6.24.080 (part) (Ord. 70-9-664 § 1 (part)))
