(a) The Sewer Rental Fund is an account into which collections from sewer service charges are deposited. The Sewer Rental Fund shall be used to pay the costs of management, administration, operation and maintenance (including replacement) of the sewage works; the debt service resulting from capital improvements to the sewage works; land acquisition costs; and additions to the sinking fund for retirement of the debt.
(b) That portion of sewer service charges collected for operation, maintenance and replacement (OM&R) costs shall be accounted for separately and shall be utilized only for those costs associated with OM&R. A portion of the funds collected for OM&R, but not less than one hundred and fifty thousand dollars ($150,000) per annum, shall be deposited in an interest bearing account (Sewerage Works Replacement), the principal and interest from which shall be restricted in use to offset major maintenance and/or replacement costs associated with; but not necessarily limited to, the major equipment items set forth in subsection (c) hereof.
