All service installations connected to the water and sewerage system that have been abandoned or, for any reason, have become useless for further service shall be forthwith disconnected at the main. The owner of the premises served shall pay all costs of excavation, capping, main and street restoration. The city shall perform the actual disconnection and all pipe and appurtenances removed from the street right-of-way shall become the property of the city. It is unlawful for any person to cause or allow any service pipe to be hammered or squeezed together at the ends to stop the flow of water, or to save expense in improperly removing the pipe from the main. Also, the improper disposition thereof shall be corrected by the city and the cost incurred shall be borne by the person causing or allowing the work to be performed. If any property owner shall fail to pay the costs incident to services performed under this section, the city may collect payment therefor as any other utility charge.
