Written by GovTribe AI ·

This document is a Preventive Maintenance and Inspection (PMI) Schedule for a Wastewater Treatment Plant (WWTP). The schedule outlines 77+ maintenance tasks across multiple system components with varying frequencies ranging from daily to annual intervals.

The schedule covers maintenance for backflow preventers (three locations), lift/sewage stations (two stations with dual pumps each), surge tanks (three pumps and two blowers), aeration basins (two blowers), settling tanks/clarifiers, tertiary tanks (two blowers and mudwell pumps), contact chambers, dechlorination chambers, emergency generators, RV dump station septic tanks, potable water lines, and effluent flow meters. Daily inspection tasks include visual checks on all pumps and blowers, air scour and backflush of tertiary filters, and washdown of settling tank walls. Weekly tasks involve float inspections, belt inspections, bearing lubrication, and blower alternation. Quarterly work includes pump impeller inspections and tertiary filter cleaning. Semi-annual maintenance (March/September and May/November) encompasses backflow preventer inspections, pump and impeller removals, filter replacements, belt replacements, and full tank pumpouts with touch-up painting. Annual tasks include mudwell pump removals, emergency generator fuel/oil checks (with biweekly checks during hurricane season July-November), RV septic tank pumpouts timed before Memorial Day, Independence Day, and Labor Day, potable line analytical testing, and effluent flow meter calibration. Grease removal at the lift stations is scheduled as-needed, approximately 6-8 times annually. The document includes blank columns for recording completion dates and notes regarding operational feasibility for submerged pump inspections.

Lift/Sewage station pumps, Surge tank pumps, and Tertiary mudwell pumps are always submerged in water therefore a visual inspection isnt feasable. Daily operation check may be more practical.
