About this file

This document is a Preventive Maintenance and Inspection (PMI) Schedule for a Wastewater Treatment Plant (WWTP) that establishes maintenance tasks, frequencies, and completion tracking across multiple systems and components.

The schedule encompasses approximately 76 distinct maintenance tasks distributed across frequency categories: Daily (D), Weekly (W), Biweekly (B), Monthly (M), Quarterly (Q), Semi-Annual (S), and Annual (A) activities. Key systems requiring maintenance include Lift/Sewage Stations (#1 and #2 with multiple pumps), Surge Tank (three pumps and two blowers), Aeration Basin (two blowers), Settling Tank/Clarifier, Tertiary Tank (two blowers and mudwell pumps), Contact Chamber, Dechlorination Chamber, Emergency Generator, RV Dump Station Septic Tank, Back Flow Preventers (three locations), and Potable Water Lines. Daily visual inspections are required for numerous pumps and blowers, while weekly tasks include float inspections, belt inspections, bearing lubrication, and alternating blower operations. Semi-annual activities focus on filter and belt replacements (May/November), pump-outs and paint touch-ups (April/October), and back flow preventer inspections (March/September). Annual tasks include mudwell pump removal and inspection, emergency generator fuel checks, and RV dump station pump-outs coordinated around holiday periods. Additional maintenance includes quarterly removal and impeller inspections for lift station pumps, monthly bearing lubrication for plant blowers, potable water analytical testing, and as-needed grease removal (6-8 times annually) at lift stations. The document provides columns for recording completion dates and includes operational notes regarding submerged pumps requiring operational checks rather than visual inspections.
