Section 17.12.750.13 - TRANSMISSION AND DISTRIBUTION SYSTEMA. Transmission Systems: The transmission pipelines from sources of supply shall be designed to deliver in combination with related storage facilities and to the limits of the capacity of those sources of supply the maximum requirements of that portion of the system which is dependent upon such transmission pipelines.B. Distribution System: (1) Minimum Pipe Sizes: The distribution system shall be of adequate size and designed in conjunction with related facilities so as to maintain the minimum pressures required herein.(2) Depth of Mains: Water mains should be installed below the frost line to prevent freezing and should have adequate cover over the top of the pipe for protection against surface loads.(3) Dead Ends: Insofar as practicable the utility shall design its distribution system so as to avoid dead ends in its mains. Where dead ends are necessary the utility shall provide a means for flushing the mains. Mains with dead ends shall be flushed as often as necessary to maintain the proper quality of the water.(4) Segmentation of System: Valves shall be provided in distribution mains at reasonable intervals so that repairs may be effected by the utility with interruptions to the service of a minimum number of customers. At intersections valves shall be installed on all connecting mains.(5) Grid Systems: Wherever feasible the distribution system shall be laid out in a properly segmented grid so that in case of breaks or repairs the interruption of service to customers can be kept to a minimum.N.M.
