Sewage Pump Maintenance Checklist
A maintenance checklist for sewage pumps and lifting stations covering impeller inspection, float switch testing, alarm verification, and chamber cleaning for below-drain foul water systems.
What is a sewage pump maintenance checklist?
A sewage pump maintenance checklist is a structured list of the 11 preventive maintenance tasks — covering visual, functional, cleaning, safety and record-keeping checks — that keep a sewage pump running safely and reliably. It groups routine checks by frequency, from daily inspections to annual servicing, so FM teams and building engineers can plan and evidence preventive maintenance.
Core sewage pump checks
- Inspect the pump chamber for fat, rag, and debris buildup
- Test float switch operation and pump start/stop levels
- Clean the pump chamber if significant buildup is present
- Test high-level alarm and confirm it reports to the BMS or monitoring system
- Record pump run times, test results, and any cleaning performed
What is a sewage pump?
A sewage pump lifts foul water and waste from below-drain locations such as basement toilets, kitchens, and shower rooms to the gravity drainage system. Sewage pumping stations typically include submersible grinder or vortex pumps in a sealed chamber with float switches, alarms, and duty/standby arrangements. These are critical systems — failure results in immediate loss of sanitary facilities and potential contamination.
This checklist is one of 25 in our plumbing and water system maintenance checklists, covering pressurisation units, booster sets, storage tanks, TMVs and water treatment — pressure, hygiene and legionella control.
Typical Sewage pump maintenance checklist
A practical starting point for planned preventive maintenance. Always refer to the manufacturer's O&M manual and site-specific requirements.
Visual Checks
- Inspect the pump chamber for fat, rag, and debris buildup
- Verify the vent pipe is unobstructed
- Inspect power cables and junction boxes for damage or moisture
- Check the chamber lid seal is intact
Functional Checks
- Test float switch operation and pump start/stop levels
- Verify the pump runs without blockage, unusual noise, or excessive current draw
- Check the discharge non-return valve and isolation valves
- Test duty/standby changeover
Cleaning & Housekeeping
- Clean the pump chamber if significant buildup is present
Safety Checks
- Test high-level alarm and confirm it reports to the BMS or monitoring system
Record Keeping
- Record pump run times, test results, and any cleaning performed
