In the event of violation of any terms of this chapter (except under Sections 15.12.060 and 15.12.070) the water department may disconnect the premises to which such violation relates from the water system after first notifying in writing the person causing, allowing or committing such violation, specifying the violation and, if applicable, the time after which (upon the failure of such person to prevent or rectify the violation) the manager will exercise his authority to disconnect the premises from the water system; provided, that such time shall not be less than five days after the deposit of such notice in the United States Post Office at Petaluma, Sonoma County, California, addressed to the person to whom notice is given; provided, however, that in the event such violation results in a public hazard or menace, then the manager may enter upon the premises without notice and do such things and expend such sums as may be necessary to abate such hazard, and the reasonable value of the things done and the amounts expended in so doing shall be a charge upon the person so in violation. (Ord. 544 NCS §8; prior code §27.29.)
