When a heavy influence of stormwater impacts a WWTP, the massive influx of extra water can effectively disrupt all levels of Treatment (Primary, Secondary, Tertiary, and Quaternary). This is especially disruptive to digestion technology (Aerobic and An-aerobic). The preferred methodology for prevention is a stormwater bypass system that absorbs the excess flow and recirculates it through a retention system until the main treatment process can incrementally facilitate treatment. The key critical aspect for success in managing this circumstance is to have comprehensive hydrologic data sets to calculate any given Region's peak flow event horizon volumes; so that your facilities bypass system is large enough to handle the excess stormwater.
