Pump technology

A lifting station, often referred to as a sewage lifting system, wastewater lifting system or pumping station, is used to convey wastewater or sewage from a lower-lying area to a higher point. It is used when wastewater cannot flow into the sewer system by a natural gradient.

Lifting stations are typically used in the following situations: 

1. Basements or underground rooms: Where rooms are situated below the level of the main sewer or the sewerage system, wastewater lifting stations are used to pump the wastewater generated in these areas up into the main sewerage system.
    
2. Remote locations: In certain cases, buildings or facilities may be located far from the nearest sewerage system. Lifting stations make it possible to transport wastewater over longer distances and discharge it into the main sewerage system.
    
3. Terrain conditions: Where the terrain does not have sufficient gradient to allow wastewater to drain naturally, wastewater lifting systems are used to pump the wastewater to a higher level.

A typical wastewater lifting system consists of various components such as a wastewater pump, a chamber or tank for collecting the wastewater, non-return valves, alarm and monitoring systems, and a control unit. The pump is activated when the wastewater level reaches a certain point and pumps the wastewater into the main sewer system or a wastewater collection system.

Lifting stations and pumping stations convey wastewater through pressure pipes above the backwater level, before discharging it into the public sewer system. They are primarily used to protect drainage points located below the backwater level from water ingress. So what distinguishes them from other backwater valves such as backwater valves? Quite simply: whilst a backwater valve completely blocks the pipe in an emergency, you can continue to use your drainage points without any problems even in the event of backwater thanks to pump technology. This is because lifting stations and pumping stations pump the wastewater high enough to ensure it can always flow in the direction of the sewer.

In addition to traditional lifting stations and pumping stations, pump technology now also includes innovative hybrid lifting stations, which offer an environmentally friendly and cost-effective alternative for backwater protection.
