Pump Chambers & Pump Stations

Water & sewage Individual sewer & drainage Pump Chambers & Pump Stations

Efficient and reliable water management begins with the right underground equipment. In our extensive range of pump chambers and pump stations, you will find proven solutions for conveying stormwater, drainage water, greywater (from sinks, showers, and laundry), and blackwater (from toilets). These products are primarily used when gravity flow is not possible and wastewater must be pumped upwards or over long distances to a municipal connection point, septic tank, or infiltration bed.

We offer everything from prefabricated pump chambers made of durable plastic for single-family homes and holiday cottages to powerful sewage pump stations designed for challenging ground conditions and larger properties. Our systems are often supplied complete with tailored pumps, pipe fittings, check valves, and level controls to ensure minimal maintenance and safe, year-round operation. Choose the right pump chamber from us to ensure a reliable, approved sewage system that protects your property against flooding and operational downtime.

Guide to Choosing the Right Pump Chamber and Pump Station

When sewage or drainage lines lie below the level of the municipal connection or your own on-site sewage system, a pump chamber or pump station is a necessary investment. The choice of system depends on the type of water, flow requirements, and the ground conditions around the property. Installing a complete, properly sized solution ensures trouble-free operation and effective handling of the property's wastewater, regardless of the season.

Differences between types of water and pumps

The type of liquid to be pumped is the most critical factor when selecting a pump station:

  • Blackwater (toilet waste): Requires a pump station equipped with a vortex impeller pump or a grinder pump. Grinder pumps break down toilet paper and fecal matter into a fine slurry, allowing it to be transported through smaller-diameter pipes without the risk of clogging.
  • Greywater (bathing, dishwashing, laundry): Contains no toilet waste and can be handled by pumps designed for particle-laden wastewater with a free passage capability.
  • Drainage and stormwater: Consists of relatively clean surface water and groundwater. Drainage pump chambers with open impellers and particle-handling capabilities suited for sand and silt are used here.

Key factors for purchase and installation

  1. Chamber depth and diameter: The chamber must have sufficient volume to ensure reasonable pump run times—avoiding excessively frequent starts and stops—thereby extending the pump's service life. The depth must also align with the depth of the inlet pipes below ground level.
  2. Climate adaptation and frost protection: In Nordic climates, the chamber and pressure pipe must be installed below the frost line or, alternatively, fitted with appropriate insulation or self-regulating heating cables at penetration points. Pump type and lift height: Calculate both the geometric lift height (the vertical distance from the bottom of the sump to the discharge point) and friction losses in the piping to ensure the pump delivers the recommended flow rate.
  3. Level control and alarms: Most systems are controlled automatically via float switches or pressure sensors. Always supplement the installation with an external level and high-water alarm to quickly detect any operational interruptions.
  4. Check valve and shut-off valve: These ensure that pumped water in the discharge line does not flow back into the sump when the pump stops, and they facilitate servicing without requiring the entire piping system to be drained.

Choosing a prefabricated sump saves time during installation, as the piping, pump base, and quick-connect couplings are often factory-installed. Please note that electrical installations must be performed by a qualified installer to comply with applicable electrical safety regulations.
