Municipal waste water company

Städtische Abwasserbetrieb Beckum is responsible for the operation and maintenance of the entire public sewer network in Beckum.

A core activity of sewer maintenance is the regular monitoring and cleaning of the sewers. The Beckum municipal sewage company is supported in this by external companies equipped with their own flushing and suction vehicles.

Rainwater or drainage water that is discharged into the wastewater sewerage system causes problems for the downstream sewerage system and sewage treatment plants. For this reason, sewer maintenance also includes checking the connections of private, commercial or industrial properties to the public sewerage system.

If, for example, the roof drainage system is not connected to the rainwater sewer but to the wastewater sewer by mistake, the property owner is requested to remove this incorrect connection.

Sewer rehabilitation involves the repair and renovation of drainage sewers using a closed construction method.

The data collected during the sewer inspection is recorded and the damage found is assessed and classified with regard to the basic requirements of tightness, stability and operational safety. Taking into account the damage pattern, the damage class, the resulting rehabilitation priority and other boundary conditions, the sewer sections in need of rehabilitation (sewer section between two inspection chambers) are rehabilitated within predefined deadlines.

  • Inspection chamber - Inspection chamber

    A suitable inspection chamber with a diameter of at least 400 mm must be installed and operated by the property owner on all properties connected to the public sewage system.

    Inspection chambers must be freely accessible at all times. They must not be built over, paved over or planted over. This is also in the interest of every property owner, as in the event of possible blockages - or for the leak tests to be carried out - the inspection is always carried out from the inspection chamber.

  • Backflow prevention

    Do you have a backflow preventer for your home?

    All wastewater pipes in a building that drain wastewater from drainage objects (e.g. washbasin, toilet, shower, washing machine) form a pipe system connected to the public sewer. If the wastewater backs up in the sewer due to heavy rainfall or blockages, it simultaneously pushes back into all connected pipes, including the pipes in the house. There, the sewage rises up to the top of the street, the so-called backwater level, and can flood all areas of the house below (e.g. the cellar). In this case, the water pushes back through the floor inlets, from the washing machine or even from the toilet.

    To avoid such a scenario and to protect the property owner from it, every property owner must protect themselves against backwater from the sewerage system.

    The homeowner is responsible for the installation and proper functioning of the backflow protection or pumps. To ensure that the backflow protection system works properly, it should be serviced regularly. Especially after a long dry period, every homeowner should check their backwater valves for mobility and functionality. Depending on the design, the devices should be cleaned and made smooth-running. If present, the connected electrical system must also be checked.

    Remember: Only functional backflow flaps can prevent backwater from entering the cellar via the underground pipes during heavy rain events. And the next storm is sure to come...

  • Small sewage treatment plants

    The town of Beckum, and therefore the municipal wastewater company, is responsible for wastewater disposal not only for the properties and buildings connected to the sewer network, but also for the so-called "rolling sewer".

    Behind the "rolling sewer" is the collection of sewage sludge with suction vehicles that transport it to the Beckum sewage treatment plant.

    The fees are based on the current statutes, which you can find under this link:


    If you would like to install a new small wastewater treatment plant or apply for the necessary water rights (discharge of treated wastewater into the groundwater or a body of water), your contact is the Warendorf District Water Authority, Environmental Agency, telephone 02581/53-6616.


  • Sewer network

    Städtische Abwasserbetrieb Beckum operates and maintains over 249.95 kilometres of sewer system with 6,436 inspection chambers and various special structures and pumping stations for the collection and transport of wastewater.

    The sewer network is divided into combined sewers, wastewater sewers and stormwater sewers. In combined sewers, wastewater and rainwater are drained through a common pipe.

    In the separation system, rainwater and wastewater run through separate pipes. Where possible, the rainwater is channelled into a body of water. Depending on the degree of pollution, the rainwater is cleaned before being discharged. The wastewater from the entire city of Beckum is channelled to the sewage treatment plants in Beckum and Neubeckum and treated there.

  • Special structures

    The sewer network also includes a large number of special structures.

    Typical special structures in Beckum are

    • Pumping stations to transport the wastewater further if the gradient is insufficient
    • Stormwater overflows to relieve combined sewers
    • Stormwater overflow basin for cleaning and storing combined sewage
    • Rainwater clarifier for cleaning polluted rainwater
    • Rainwater retention basin for the temporary storage of rainwater
    • Culvert for crossing under bodies of water and obstacles
