Equations for wetted area and perimeter improve hydraulic calculations in Cleveland's egg-shaped sewers, suggesting enhanced sewer management strategies.
Wastewater professionals working with combined sewers often encounter a variety of non-circular sewer cross sections, including egg-shaped sewers. Equations are developed here to calculate the wetted area, wetted perimeter, and surface width for various Cleveland egg-shaped sewers flowing partially full and support a variety of hydraulic calculations. This paper describes the geometry of No. 4 through No. 20 Cleveland egg-shaped sewers. These equations supplant traditional graphical approaches that use geometric and hydraulic elements curves in favor of equations better suited to Smart Sewer applications. The equations are validated and provide a concise reference for those working with egg-shaped sewers in combined sewers located in Cleveland, Ohio.
