Where each walk sits in the schedule

  1. 01quarterly

    Sewage lift station quarterly maintenance checklist

    Every quarter. Confined-space entry into the wet well is a permitted procedure; inspect from grade unless entry is separately authorized under a permit.

    Run by: The plumbing or facilities tech on the quarterly round, working from grade at the wet well.

  2. 02annual

    Sewage lift station annual maintenance checklist

    Once a year. Pumps are lifted on the guide rails from grade; any entry into the wet well runs under an authorized confined-space permit, not as a routine step.

    Run by: The plumbing service crew on the annual visit, with a hoist and a confined-space permit where entry is authorized.

What most often fails on a sewage lift station

  • Both pumps assumed running because the well pumps down, when really the lead pump is doing everything and the lag never alternates in.
  • Floats fouled with grease and rags so they hang at one level, and the station either short-cycles or lets the well climb toward overflow.
  • High-level alarm and telemetry never tested end to end, so a failure at 2 a.m. calls no one and the first sign is a backup upstairs.
  • Guide rails and lifting chain corroded so a pump can't be pulled cleanly when it fails, turning a routine swap into an emergency.
  • Check valve stuck part-open, letting the well backfill each time the pump stops so the pumps short-cycle and burn out early.
  • Isolation valves seized, so a single pump can't be isolated for service without shutting the whole station down.

Verified against

Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
