Sewage Lifting Equipment — Reliable Wastewater Management for Underground Spaces
When gravity drainage isn’t possible — in basements, underground stations, or remote restrooms — wastewater needs a reliable way up and out. Chaodun Pump’s Sewage Lifting Equipment provides exactly that: a compact, automated system that collects wastewater in a sealed tank and pumps it to the main drainage line on demand.
Powerful, Clog-Resistant Discharge
The core of this system is a high-efficiency sewage pump designed to handle solid waste and fibrous materials without clogging. With a flow range of 5-100 m³/h and head capability of 3-50 meters, it covers everything from small residential installations to large commercial facilities. The motor power ranges from 0.55 to 15 kW, matching the specific duty point of each application.
The impeller design allows solids to pass through without jamming, which means fewer blockages, less downtime, and lower maintenance costs over the equipment’s operating life.
Sealed, Odor-Free Operation
Unlike open sump pits that release odors and require frequent cleaning, this lifting equipment uses a fully sealed collection tank. All wastewater enters and exits through closed piping, eliminating exposure to the surrounding environment. This hygienic approach is especially important for indoor installations in commercial buildings, hospitals, and food service areas.
Fully Automated — Minimal Human Intervention
The system runs on automatic level control. When the wastewater in the sealed tank reaches a preset high level, the pump starts and discharges to the main drain line. When the level drops to the low setpoint, the pump stops. No manual valve operation, no daily checks, no operator presence required. This automation significantly reduces the workload for facility maintenance teams.
Compact Footprint, Easy Installation
The integrated design combines the collection tank, pump, and control system into a single compact unit that fits into tight mechanical rooms or utility spaces. Installation requires minimal civil work — connect the inlet pipe from the fixtures, connect the outlet pipe to the main drain, plug in the power, and the system is ready to operate.

Typical Applications
This equipment is commonly specified in the following environments:
- Basements and underground parking — Toilet and shower drainage where gravity connection is unavailable
- Subway stations — Platform and concourse wastewater collection
- Underground shopping malls — Food court and restroom drainage
- Civil air defense facilities — Emergency wastewater management in underground shelters
- Restaurants and catering facilities — Kitchen wastewater lift to main sewer
- Hotels and bathhouses — Drainage from lower-level wet areas
- Hospitals and clinics — Sanitary wastewater collection from basement floors
- Any location far from drainage risers — Where conventional gravity drainage is impractical or too costly to install
How It Works
Wastewater from fixtures (toilets, sinks, floor drains) flows into the sealed collection tank through inlet piping. Inside the tank, float switches or level sensors monitor the water level. When the level reaches the high setpoint, the control system activates the discharge pump, which pushes the wastewater through the outlet pipe and into the main sewer line. Once the level drops to the low setpoint, the pump stops automatically. The entire process is sealed and odor-free.
Maintenance Considerations
While the system is designed for low maintenance, periodic checks ensure reliable long-term operation:
- Inspect the tank and piping quarterly for leaks or corrosion
- Test the float switch or level sensor operation every six months
- Check pump performance (flow, pressure, vibration) during annual servicing
- Keep the access cover sealed when not performing maintenance to maintain the odor-free environment
Frequently Asked Questions
Q: What types of wastewater can this equipment handle?
It handles typical domestic sewage including toilet waste, greywater from sinks and showers, and light commercial wastewater. For industrial or heavily contaminated waste, consult with our engineering team for a customized solution.
Q: Can it be installed in an existing building?
Yes. The compact, self-contained design makes it suitable for retrofitting existing buildings. As long as there is space for the unit near the fixtures needing drainage, installation is straightforward.
Q: What happens during a power outage?
The system requires electrical power to operate. For critical installations, we recommend connecting the control panel to a backup power supply or UPS to maintain operation during outages.
Q: How do I know when maintenance is needed?
The automated control system monitors pump operation. If an abnormal condition occurs (overload, dry running, blockage), the system will trigger an alarm. Routine preventive maintenance on a quarterly or semi-annual basis is still recommended to catch issues before they cause alarms.
