Each person who is moving from a premises for which they were required to subscribe for sewer service shall give the department written notice of their intention to move from the premises at least two (2) days prior to the date of their move. Said notice shall specify whether the premises will continue to be inhabited following their departure and the name of the owner of the premises. Failure to give the required notice means the person shall remain jointly and severally liable for all sewage removed from the premises until the department receives the notice required by this section. Upon receipt of the notice required by this section, a bill shall be rendered and such bill shall be payable immediately. In no case will the bill be less than the monthly minimum specified in the current sewer rate schedule for the class or classes of sewer service theretofore furnished. [Ord. 94-12S § 10; prior code § 11.12.100(1).]
