(a) In fixing the rates for any water or sewer utility, the Commission may fix such rates on the ratio of the operating expenses to the operating revenues, such ratio to be determined by the Commission, unless the utility requests that such rates be fixed under G.S. 62-133(b). Nothing in this subsection shall be held to extinguish any remedy or right not inconsistent herewith. This subsection shall be in addition to other provisions of this Chapter which relate to public utilities generally, except that in cases of conflict between such other provisions, this section shall prevail for water and sewer utilities.
(b) A water or sewer utility may enter into uniform contracts with nonusers of its utility service within a specific subdivision or development for the payment by such nonusers to the utility of a fee or charge for placing or maintaining lines or other facilities or otherwise making and keeping such utility's service available to such nonusers; or such a utility may, by contract of assignment, receive the benefits and assume the obligations of uniform contracts entered into between the developers of subdivisions and the purchasers of lots in such subdivisions whereby such developer has contracted to make utility service available to lots in such subdivision and purchasers of such lots have contracted to pay a fee or charge for the availability of such utility service; provided, however, that the maximum nonuser rate shall be as established by contract, except that the contractual charge to nonusers of the utility service can never exceed the lawfully established minimum rate to user customers of the utility service.
