Berliner Wasserbetriebe (BWB)

SINA for a secure supply of water

For more than 150 years now the Berliner Wasserbetriebe (BWB) – as the largest water utility company in Germany – have been supplying some four million people in and around Berlin with drinking water and treat the waste water. That means: Approximately 220 million cubic metres of drinking water per year is made available to meet demand, then disposed of and treated after use.

Both the drinking water supply and the sewage disposal have to be guaranteed at all times, therefore malfunctions of this complex system must be able to be eliminated quickly.

To this end, two measures were taken:

  • A stand-by service was established directly in parallel with the development of the management system and the “going live” of the first automated works in 2002.
  • To facilitate a rapid reaction for the stand-by services, a remote dial-in was set up. 

Security requirements increase

Due to the ever worsening security threat situation of recent years, the existing remote dial-in was to be updated and thereby designed to be more secure and holistic. The objective: The new solution should be more secure and user-friendly than the remote dial-in previously used. The renewal of the management system focussed on a holistic approach in order to secure the process control technology. Recommendations from the National Strategy for the Safeguarding of Critical Infrastructures (CRITIS), the Federal Ministry of the Interior and the implementations of the Bundesverband der Energie- und Wasserwirtschaft e.V. (Federal Association of Energy and Water Industries) in the white paper “Security in Automation“ deepened the security requirements and gave good orientation.
