Problem
A duplex wastewater lift station shows intermittent high-level alarms, longer-than-normal pump run times, and inconsistent drawdown even though lead-lag alternation appears to be functioning.
Assessment
RMS starts by checking the station as a complete operating system, comparing wet-well behavior, lead-lag sequencing, operating current, available discharge observations, check-valve behavior, accessible piping condition, and pump response during drawdown.
Service Scope
- Confirm wet-well level behavior and lead-lag sequencing
- Record operating current and available discharge observations
- Remove, clean, and inspect the affected pump
- Review check-valve behavior and accessible discharge components
- Verify rotation, current draw, sequencing, and drawdown after reinstallation
Technical Details
- Duplex wastewater lift station operating behavior
- Wet-well drawdown and high-level alarm response
- Lead-lag sequencing, operating current, and check-valve observations
- Pump removal, cleaning, inspection, and reinstallation support
Return-to-Service Standard
The return-to-service target is predictable drawdown, normal sequencing, and documented observations that help operators recognize future changes before they become emergency calls.
