Wastewater treatment accounts for about 3–4% of the US electrical energy load, which is ~ TWh/year, or equivalent to million households' annual electricity use (McCarty et al., ). Normally, at sewage treatment works, flows up to three DWF are given full treatment; >6 DWF (since they are diluted by the surface water) require only preliminary treatment. Flows between three and six DWF are stored temporarily and given full treatment. However, care needs to be taken in the design of overflow structures, particularly for flows >6 DWF.

The need for advanced methods of treatment/disposal did not exist early on in the United States — i.e., not until the late s/early s, primarily because of the higher/closer availability of larger rivers and streams to receive and acclimate the sewage, and (in later years, when the “sewage discharge” issue versus the “water.
