All testing and chlorination shall be done before the installation of service lines. Water Supply 4 -14 C. Preliminary Flushing 1. Prior to chlorination, the main shall be flushed as thoroughly as possible with the water pressure and outlets available. The Village Engineer shall be notified before any water is drawn from Village mains, and only Village employees shall operate filling valves. 2. Flushing shall be done after the pressure test is made. Flushing shall affect a velocity in the main of at least two and one -half (2 %) feet per second. 3. Corporation stops shall be provided at the end of dead end mains without hydrants to allow for flushing and chlorination. D. Disinfection 1. The preferred point of application of the chlorinating agent shall be at the beginning of the pipeline extension or any valved section of it and through a corporation stop in the top of the newly laid pipe. The injector for delivering the chlorine gas into the pipe should be supplied from a tap on the pressure side of the gate valve controlling the flow into the pipeline extension. 2. Water from the existing distribution system or any other source of supply shall be controlled so as to flow slowly into the newly laid pipeline during the application of chlorine -gas. The rate of chlorine mixture flow shall be in such proportion to the rate of water entering the pipe that the chlorine dose applied to the water entering the newly laid pipe shall be at least fifty (50) ppm, or enough to meet the requirements during the retention period. 3. Valves shall be manipulated so that the strong chlorine solution in the line being treated shall not flow back into the line supplying the water. The pipe section being chlorinated shall be kept at a lower pressure than the water system pressure. 4. Treated water shall be retained in the pipe long enough to destroy all spore - forming bacteria. This retention period shall be at least twenty -four (24) hours. After the chlorine- treated water has been retained for the required time, the chlorine residual at the pipe extremities and at other representative points shall be at least 25 ppm. Water Supply 4 -15 5. In the process of chlorinating newly laid pipe, all valves or other appurtenances shall be operated while the pipeline is filled with the chlorinating agent. 6.

All disinfection, as required by this Section, shall be performed by an independent firm exhibiting experience in the methods and techniques of this operation, and shall be approved by the Village. E. Final Flushing and Testing 1. Following chlorination, all treated water shall be thoroughly flushed from the newly laid pipeline at its extremities until the replacement water, throughout its length, upon test, has a CL2 residual of typical supply water or less. 2. The sample tap shall be located and installed in such a way as to prevent outside contamination. Samples should never be taken from an unsterilized hose or from a fire hydrant because such samples seldom meet current bacteriological standards. 3. After final flushing and before any new water main is connected to the distribution system, two consecutive sets of acceptable samples, taken 24 hours apart, shall be collected from the new main. At least one set of samples shall be collected from every 1,200 feet (366 m) of the new water main, plus one set from the end of the line and at least one set from each branch, with notice given, so that the collection may be witnessed by the Village. 4. Bacteriological sampling and analysis of the samples shall be performed by a laboratory approved by the Illinois Department of Public Health and the Village. 5. Should the initial treatment result in an unsatisfactory bacteriological test, the procedure shall be repeated until satisfactory results are obtained. 6. The contractor or developer shall pay for the sampling and analysis. Results shall be transmitted by the laboratory directly to the Village. Test results shall indicate the date the sample was made, the exact locations at which samples were taken, the firm submitting the sample, and the project at which the samples were collected. Sufficient samples shall be collected in order to ensure that the system is bacteriologically safe. Water Supply 4 -16 7. The Village shall operate the valves, hydrants, and any other appurtenances to flush the water main after the receipt of satisfactory water samples. Any operation difficulties or deficiencies shall be noted and submitted to the developer or contractor for repair. F.
