Abstract: This paper presents summary details of a 1990 technical evaluation of the impacts of water conservation on the performance of several hypothetical secondary wastewater treatment plants. The primary objective of the evaluation was to project the effect of water conservation programs on wastewater flows, treatment processes and, ultimately, on the quality of the final wastewater treatment plant effluent. The technical evaluation was conducted using previously developed U.S. EPA diagnostic models. Both fixed film and suspended growth processes were modeled and observations included both positive and negative results.
