So now calculate the total rainfall volume in gallons over the drainage area served by the facility [East Jefferson, Conner Creek, and Fox Creek sewer districts, Grosse Pointes, Harper Woods, St Clair Shores, Eastpointe, and Roseville], subtract in system storage volumes, and divide by the storm duration to get the hourly excess flowing into the station. Don't forget to include the Freud pumping station capacity as well.
