Sewage treatment rates herein established, whether charged by the District or the city, are based on the underlying assumption that all metered water consumption is eventually returned to the sewage treatment system. Where it can be evidenced that the proportion of water actually returned to the treatment system by an individual customer is significantly different from the metered consumption, charges shall be determined as provided in §§ 50.185 through 50.194 of this chapter.
