915.03 USER CLASSES.
   Every person whose premises are served by the treatment works shall be charged for the services provided. These charges are established for each user class, as defined, in order that the treatment works shall recover, from each user and user class, revenue which is proportional to its use of the treatment works in terms of volume and load. User charges are levied to defray the cost of operation and maintenance (including replacement) of the treatment works and to provide funds to pay debt service costs. User rates shall be uniform within a user class.
   (a)    User charges are subject to the rules and regulations adopted by the United States Environmental Protection Agency, published in the Federal Register May 12, 1983, (40 CFR Part 35). Replacement costs, which are recovered through the system of user charges, shall be based upon the expected service life of the sewage works equipment.
   (b)    The various classes of users of the treatment works for the purposes of this chapter, shall be as follows:
         Class 1 - Residential
         Class 2 - Commercial
         Class 3 - Industrial
         Class 4 - Governmental/lnstitutional.
