The foregoing limitations upon tax rates, insofar as they are applicable to cities, villages and incorporated towns of less than 500,000 population, may be increased or decreased under the referendum provisions of the General Revenue Law of Illinois.
The corporate authorities may, in addition to the levy of a garbage tax, finance the establishment and maintenance of systems or plants, by contract or by direct provision, for the collection and disposal, treatment or recycling or solely for the collection or solely for the disposal, treatment or recycling of garbage, refuse and ashes by service charges to be collected from persons, firms and corporations receiving service. Such service charges shall be established as can reasonably be expected to yield revenues not in excess of contract obligations and the costs of operation, maintenance, and an adequate depreciation fund. If a city, village or incorporated town assesses a service charge, the schedule of charges shall be adopted by ordinance, and a copy of the schedule shall be furnished to each customer.
