13.16.010 - Authority of city administrator.¶
The city administrator shall have charge of the supervision and administration of the water service furnished by the city. The city administrator shall prescribe, from time to time, as he deems necessary or desirable, additional rules and regulations, and amendments thereof, relating to conditions of service, deposit requirements, the application, administration and interpretation of rates, and the sale of water by the city, and of products, commodities and service incidental thereto, and the charges to be made therefor. Such rules and regulations shall be of general application, not inconsistent with the provisions of this chapter.

In the event water pressures are in excess of any consumer's normal requirements, it shall be the responsibility of such water consumer to install such devices on his own premises to protect his plumbing and/or to reduce the pressure for his normal needs.
All persons applying for or receiving water service shall be required to accept and shall be deemed to have consented to all provisions of this chapter and to such conditions of pressure and service as are provided by the system at the location served, and to hold the city harmless from any damages arising out of low pressure or high pressure conditions or interruptions of service.

13.16.030 - Emergency shutoff.¶
The city shall have the right at any time to shut off, ration or apportion water by reason of any emergency or shortage of water supply, or for making repairs, modifications, changes or other work in the water service facilities. In cases of such shutoff, rationing or apportionment, the city shall notify the affected water users, if possible, prior to such action being taken. The city shall not be responsible for any damages which may occur due to any such action. The owner and/or consumer shall be conclusively presumed to have taken all necessary precautions in compliance with the building codes and regulations of the plumbing code and any other city ordinances or regulations in anticipation of such action.

Such facilities shall be maintained, repaired and renewed by the city when rendered unserviceable through ordinary wear and tear; provided that, where replacements, repairs or adjustments are rendered necessary by an act, negligence or carelessness of the consumer or his representative, any expense caused to the city thereby shall be charged against and be collected from the consumer.
(e) Except as otherwise specifically provided in this chapter, all water delivered by the city shall be delivered through approved meters installed by the city.
