Abstract Submission: Designing a trench style pump station wet well matching Hydraulic Institute standards can lead to a false sense that the design will meet all hydraulic approach condition requirements established by the Hydraulic Institute. Robert Sanks and Theodore Williams documented several physical caveats that needed to be addressed in their paper “Design of Trench-Type Wet Wells for Pumping Stations”, Pumps & Systems, May 2008. This presentation addresses a recent project modeling a trench style wet well with computational fluid dynamics (CFD) and how each modification to improve hydraulic conditions matched the recommendations from the Sanks/Williams paper, validating their findings. CFD modeling was successfully used to aid in the design process and to document the improved pump approach conditions.
Learning Objectives/Expected Outcome (Optional) : The learning objective is to show how CFD modeling matched existing literature which shows that a trench style wet well matching Hydraulic Institute standards will often need several modifications to meet pump station hydraulic requirements.
