All revenues derived from these rates and charges are to be credited to the Public Utilities Revenue Accounts. Such revenue may be used only for the purpose of paying the cost of operating and maintaining the public sewer system and the water supply system, paying charges made by Metropolitan Council Environmental Services, providing an adequate depreciation fund, paying costs of meter-reading, billing, collection, and other similar or related sewer operating expenses, provided that any surplus above such needs may be transferred to the general funds.
