City of Morgan Hill Sewer System Master Plan 2017

x Peak Wet Weather Flow (PWWF). The PWWF is used for designing the capacity of the collection system, while allowing acceptable amounts of surcharging in the system. The design flows used in evaluating the capacity adequacy of the sewer collection system are summarized on Table 5.4 . The table lists the maximum day and peak hour flows for dry and wet weather conditions. PDWF and PWWF used for evaluating the existing collection system were estimated at 5.4 mgd and 7.7 mgd, respectively. The PDWF and PWWF used for designing the General Plan buildout system, including growth, were estimated at 8.0 mgd and 10.5 mgd, respectively.
