When a water service has been shut off or disconnected by the city for any cause, and the service is re-connected or turned back on by the owner or occupant, or for the benefit of the owner or occupant, no remission of rates will be made on account of its having been shut off. In cases where a meter reading is not available the director shall estimate the monthly charge from the date the city shut-off or disconnected the service. In addition to the charges for water an "unauthorized activation fee" shall be charged to the account. The director, in order to prevent further unauthorized connections at the premises served, may shut off the water at the main, or remove a portion of the service connection in the street. If the owner of the property was responsibile for, or directly benefited from, the unlawful activation the actual cost of cutting out and reinstating the water supply shall be charged against the account for the premises.
