(415 ILCS 45/2) (from Ch. 111 1/2, par. 502)

Sec. 2. A properly certified water supply operator may operate a waste effluent treatment facility which is a part of a water supply treatment plant, notwithstanding the fact that such operator is not a certified waste treatment operator, provided, however, that the primary function of such plant is water supply treatment rather than waste effluent treatment and that such waste is generated by processes of water supply treatment.
