WebbThe peaking factor will be less during heavy flows than during normal flowrates. This reflects the relatively constant supply of infiltration which occurs only when the groundwater is high. Peaking factors developed from dry-weather periods do not reflect the diminished peaking caused by infiltration, and should not be applied to the PIF5.

WebbWhen you design, you design for mostly just your sanitary sewer flows but there is a factor in there for some peaking that you’re going to get, no matter how tight you build the sanitary sewer system. But there’s excessive peaking that can come, especially with older systems, that is beyond that design level anticipated peak flow. Webbg.
