On or before March 1 of each year, the Public Utilities Director shall submit to the Director of Public Service a recommended system of user charges for approval. If approved, the Director of Public Service shall submit the sewer use charge schedule to the first regular meeting in March of Council for ratification and incorporation into the ordinances of the City. The system shall be in accordance with the following requirements:
(a) The system shall result in the distribution of the costs of operation and maintenance of the treatment works within the Department's jurisdiction to each user class in proportion to such user's contribution to the total wastewater loading of the treatment works. Factors such as strength, volume and delivery flow rate characteristics shall be considered and included as the basis for the user's contribution to ensure a proportional distribution of operation and maintenance (including replacement) costs to each user's class.
(b) The system of charges shall be reviewed annually and revised periodically to reflect actual sewage disposal works operation and maintenance costs.
(c) The system of charges shall generate sufficient revenue to offset the costs of all sewage disposal works operation and maintenance provided by the Department and such other expenditures that may be authorized.
