Contracts for water service are not transferable. Any person wishing to change from one location to another shall make a new application and sign a new contract. If any consumer shall move from the premises where service is furnished, or if the said premises is destroyed by fire or other casualty, he shall at once inform the Water Commissioner/Public Works Commissioner who shall cause the water service to be shut off at the said premises. If the consumer should fail to give such notice, he shall be charged for all water used on the said premises until the Water Commissioner/Public Works Commissioner is otherwise advised of such circumstances.
