Product Overview

The Sewage Lifting Station is an integrated wastewater pumping system designed for locations where gravity drainage to the main sewer line is not possible. The system collects sewage from sanitary fixtures below the sewer line level and automatically pumps it to the main sewer or septic tank, enabling full utilisation of basement and underground spaces without the need for excavation and gravity-based drainage installation.

This system is widely used in residential basements, commercial underground facilities, subway stations and healthcare institutions. Depending on regional terminology, it may also be referred to as a Sewage Pumping Package, Wastewater Lifting System, Sewage Lifting Device or Sewage Lifting Station.

Customer Benefits

Powerful Sewage Discharge Capability

The anti-clogging pump design handles sewage containing solids and fibres without blockages, ensuring reliable wastewater discharge from basement and underground installations even under demanding conditions.

Environmentally Friendly Operation

The fully enclosed sealed tank prevents odour emission and groundwater contamination, making the system suitable for installation in occupied buildings and environmentally sensitive areas.

Maintenance-Free Design

The self-cleaning tank bottom design eliminates sediment accumulation, reducing the need for manual cleaning and maintenance, lowering operational costs and improving hygiene conditions.

Compact Space-Saving Footprint

The integrated system configuration requires minimal installation space, making it suitable for utility rooms, equipment closets and other space-constrained installations.

Straightforward Installation

The pre-fabricated tank and standardised inlet/outlet connections simplify installation procedures, reducing installation time and costs compared to traditional wet-well pumping stations.

Automatic Reliable Operation

The level-controlled automatic operation with dual-pump alternation ensures continuous reliability even during pump maintenance or failure, providing dependable wastewater discharge without manual intervention.

Selection Guidance

To select the appropriate sewage lifting station, please provide the following information:

• Number and type of connected sanitary fixtures (toilets, sinks, showers, etc.)
• Required flow rate (m3/h)
• Required discharge head (m) and horizontal distance to sewer line
• Available installation space and location constraints
• Available voltage and frequency
• Expected sewage composition (solids, grease, chemicals)

Final model selection should be confirmed according to the actual fixture count, discharge requirements and installation conditions.

Installation and Maintenance

Installation Guidance

The sewage lifting station should be installed on a level, stable surface with adequate clearance for inspection and maintenance. The inlet connections must be connected to the building drainage system with proper slope to ensure gravity flow into the tank. The discharge piping must be properly supported and connected to the main sewer line with a non-return valve to prevent backflow.

Pre-Start Inspection

Before commissioning, confirm the following:

• Station is securely positioned on a level surface
• All inlet connections are properly sealed and connected
• Discharge piping connection is complete with non-return valve installed
• Electrical connections are correct and terminals are secure
• Level sensor is properly positioned and calibrated
• Tank lid is properly sealed to prevent odour emission

Routine Maintenance

Regular inspection should include:

• Verifying automatic pump start/stop and alternation function
• Checking pump performance and discharge flow during test cycles
• Inspecting tank and lid seal integrity
• Testing level sensor and alarm system operation
• Inspecting all piping connections for signs of leakage
• Cleaning inlet strainers when necessary

Available Configurations

• Flow rates from 5 to 100 m3/h
• Heads from 3 to 50 m
• Motor powers from 0.55 to 15 kW
• Single-pump and dual-pump configurations
• PE tank and stainless steel tank options
• Various tank sizes for different fixture counts and wastewater volumes

FAQs

What is a sewage lifting station?

It is an integrated wastewater pumping system designed for locations where gravity drainage to the main sewer line is not possible, collecting sewage from sanitary fixtures below the sewer line level and automatically pumping it to the main sewer or septic tank.

What is the flow range?

The system offers flow rates from 5 to 100 m3/h, suitable for small to medium wastewater discharge applications.

What is the head range?

Available heads range from 3 to 50 m, covering typical basement and underground facility discharge requirements.

Where can this system be used?

It is suitable for basement bathrooms, underground commercial facilities, subway stations, civil air defence projects, unmanned pumping stations, underground restaurants and healthcare institution wastewater discharge.

Does the system require manual cleaning?

The self-cleaning tank bottom design minimises sediment accumulation, reducing the need for manual cleaning. However, periodic inspection and occasional cleaning of inlet strainers and pump impeller is recommended for optimal performance.

Why use a sealed tank design?

The fully enclosed sealed tank prevents odour emission and groundwater contamination, making the system suitable for installation in occupied buildings and environmentally sensitive areas.
