Water quality volume method

Structural controls sized to treat the Water Quality Volume (WQv); primary performance goal approximately 70–80% TSS removal (Primary TSS). Integrated design also addresses streambank protection volume (SPv) and flood control. Controls may be online or offline diverting WQv to treatment.

“Ability to treat the Water Quality Volume (WQv) ... 70% TSS removal performance goal”
§1.2 / structural control selection

Peak flow calculation method(s)

Water Quality Volume (WQv), Streambank Protection Volume (SPv), Flood control / detention routing

“Water Quality; Streambank Protection; Flood Control”
