With respect to separate contributory sewersheds, is it safe to assume different peaking factors for each specific sewershed when sizing a pump station?
I am currently designing a pump station to replace to existing two pump stations. One PS serves a minor league baseball park (4 months of operation per year), and the other serves existing sanitary sewer. I am calculating flows at the ball park with a peaking factor of 10, and the existing sanitary with a peaking factor of 4. I have detailed flow data for each sewershed for the past 2 years for the ball park, and 3+ for the existing sanitary. Am I correct on this approach, or should I combine the flows and assume one single peaking factor - for example, 6.
