Excessive variability in effluent quality can cause wastewater treatment plants to fail to meet their discharge permit limits. The paper summarizes our understanding of the nature, causes, and control of the variability. It discusses studies made on the differences in performance variability observed among plants, the statistical characterization of this variability, and investigations into its causes. Methods of controlling and accommodating effluent variability are briefly reviewed.
