Sim~ar to the h~storica] analysLs, average, maximum month, maximum week, and maximum day flow rar~ges and loads were determined for both dry and wet seasons. Domestic (residential and commercial, and I/I) projections were estimated based on the population projections and the selected per capita and peaking factors ~den~ed above. The methods for dete~g average, maximum month, maximum week, maximum day, and peak hour values are listed below and refer to both flows and loadings: Average Dry Weather--Determined by multiply~g the selected per capita value by the projected population for 2005, 2010, 20:I5, 2020, 2025, and brdldozat. Average Wet Weather--Determined by mult~plyin§ the selected per capita value by the projected population for 2005, 2010, 2015, 2020, 2025, and buildouL Maximum Month---Determined by multiplying the future dry or wet weather averages for a given year by the selected maximum month peaking factor. Maximum Week~Detez~dned by multiplying the future dry or wet weather averages for a given year by ff~e selected maximum week peaking factor. ~ Maximum Day~De[errrdned by multiplying the future dry or wet weather averages ~or a given year by the selected maximum day peaking factor. Dry Weather Peak Hour F/ow---Determined by multiply~g the dry weather: average for a given year by the selected peak hour peaking factor. 4-12 MWMC_4,0_flEVS,DOC
