There is hereby imposed a system of rates and charges on each site of real property within the city served by or to which is available for service the utility established by this chapter. The rates and charges are found to be reasonable and necessary to fund the current administration, planning, design, construction, water quality programming, operation, maintenance and repair of storm and surface water utility facilities; provided, however, that the city reserves the right to fix, alter, regulate and control these rates and charges.
