The sewer user charge for all occupied property shall begin 30 days after the sewer service becomes available or the day that connection is made to the public sewer, whichever occurs first. The sewer user charge for all unoccupied property shall begin within 30 days after the property is ready for occupancy or on the first day of occupancy, whichever occurs first. Once the sewer user charge has commenced, no credit shall be given for vacancy unless the appropriate request has been made to the city for an unoccupied or temporary sewer rate; otherwise all rates shall be subject to collection whether the service is used or not.
