Each applicant desiring water or sewer service or both services shall pay a refundable deposit to the city in an amount equal to the expected billings for such service(s) for three (3) months at the premises desired to be served. The city treasurer shall determine this amount based upon pertinent past service data and the information provided in the application for utility services required by section 6-4-010 of this chapter. Such deposit shall be required unless the applicant has had with the city within the past two (2) years, one or more accounts for utility service, in his/her own name, and has had satisfactory payment record for the last twelve (12) months such account(s) was (were) in effect or the applicant may provide a letter or copies of bills from another utility for twelve (12) months of current service with such utility showing a "satisfactory payment record", or the applicant agrees to maintain automatic payment of their water or sewer service or both bills for a minimum period of twelve (12) months with a "satisfactory payment record". Failure to maintain a "satisfactory payment record" during the first twelve (12) months of automatic payment of water or sewer or both services bills for a minimum period of twelve (12) months with a "satisfactory payment record" will require that the applicant shall immediately pay such deposit in order to maintain service. A "satisfactory payment record" shall be defined as one in which all payments were made on or before the date due, for all accounts in effect during the aforementioned twelve (12) months.
