The sewer charges levied at the rates established by this chapter shall be billed on the first day of each month or quarter of the calendar year, and be payable within fifteen days after billing. Any premises making connection with the system and using the same after the first day of any calendar quarter shall be charged a per diem pro rata amount, based on the quarterly minimum charge, from the time the connection is made or the discharge into the system is begun, until the commencement of the next following billing period applicable to that premises, except that should the measured service exceed the minimum charge, the measured rate shall be charged. In case of failure to pay any bill for sewer charges when due and payable, a penalty of ten percent (10%) of the charge shall be added to the bill.
