A raw water / sewage pumping station preventive maintenance schedule lists the checks and jobs done on the equipment at fixed intervals, how long each takes, and in what order of frequency, so problems are found before the raw water / sewage pumping station fails. This page gives the schedule used in the PlantOps360 task library for raw water / sewage pumping station (: wet well, screens and pumps), which follows common industry practice for general-purpose equipment. It is also searched for as pumping station, lift station, sewage pumping, wet well.
The maker’s manual and your site safety procedures always come first where they differ. Intervals set by law differ by state.
