The first method is to analyze the wastewater flow data at the treatment facility during a dry weather period of 7 to 14 days. It is useful to choose the dry weather period during seasonal high water as you will be able to determine the peak infiltration rate at the same time. From the flow

WebDry weather flow is the flow of wastewater in a sewer system during dry weather that presents with minimal infiltration. Sewer systems depend on gravity to ensure that solids and liquids continue on their way to treatment plants. During these dry spells, a "sewer drought" can occur as the amount of liquid in the sewer is reduced. For existing discharges, you can use either the DWF formula or the Q80 method to determine DWFpermit limits at the design horizon. You must take into account future growth. The simpler approach is to use measured data to determine the Q80 value and then extrapolate it to the future Q80 value. For example, a … See more There are 2 ways to calculate the current DWF: 1.
