(A) The rates hereby fixed are estimated to be sufficient to provide for the payment of any or all indebtedness, to provide for the expenses of administration and operation and such expenses of maintenance of such system as are necessary to preserve the same in good repair and working order, to build up a reasonable reserve for depreciation thereof, and to build up a reserve for reasonable and proper improvements, betterments and extensions thereto other than those necessary to maintain the same in good repair and working order. Such rates shall be fixed and revised from time to time as may be necessary to produce these amounts. An annual audit shall be prepared. Based on said audit, rates for sewage services shall be reviewed annually and revised as necessary to meet system expenses. (`73 Code, 25.075, § 2.125)
(B) Except as otherwise provided by this chapter, the gross revenues received by virtue of this article shall be set aside and used for the operation, maintenance and extension of the sewage works.
