Ala. Code § 11-81-186: Payment by Counties, Municipalities, Etc., for Services Furnished by System.

The governing body may provide in the ordinance authorizing the issuance of bonds under the authority of this article that no free service shall be furnished by any such system or combined system to the county, city or incorporated town or to any agency, instrumentality, person, firm or corporation.

The reasonable cost and value of any service rendered to any such borrower by any such system or combined system shall, in that event, be charged against the borrower and shall be paid for monthly as the service accrues from the current funds or from the proceeds of taxes which such borrower, within constitutional limitations, is hereby authorized and required to levy in an amount sufficient for that purpose, and such funds, when so paid, shall be accounted for in the same manner as other revenues of such system or combined system.
