Bills shall be rendered monthly or quarterly and must be paid at the office of the municipal water utility during business hours or at such other place or places as may, from time to time, be determined by the utility service board. If a bill is not paid within fifteen days from the due date thereof as stated in the bill, the customer shall be considered delinquent in payment, and the municipal water utility may, at any time thereafter prior to the payment thereof after serving notice, turn off and discontinue service. Failure to receive such bill shall not entitle the customer to a new bill if he fails to make payment within such fifteen-day period, nor shall it affect the right of the municipal water utility to turn off and discontinue service for nonpayment as provided in this section. (Prior code § 33-13)
