This document summarizes considerations for designing and troubleshooting wastewater pumping systems. It discusses key topics like site selection, basis of design, design issues, and operational troubleshooting. Specifically, it covers selecting pump types and configurations, hydraulic pump design, wetwell sizing, control systems, and preventing future operational problems through thorough startup checks and understanding the original design basis.
