Donau-Stadtwerke Dillingen-Lauingen

Donau-Stadtwerke Dillingen-Lauingen, also known as DSDL, is a municipal utility that supplies electricity, water, wastewater, heating and internet services to customers in the Dillingen-Lauingen region of Germany. The organisation operates under the public utility model typical of German Stadtwerke, providing essential municipal services to both residential and commercial users. Its headquarters are located in Germany, reflecting its national registration and operational base. As a Stadtwerke, DSDL is responsible for the generation, distribution and maintenance of the utility networks that serve the local community. The service portfolio includes the provision of potable water, treatment of wastewater, supply of electrical power, district heating and broadband internet connectivity. These services are delivered through integrated infrastructure that is managed to meet regional demand.

Distinguishing attributes of DSDL include the segregation of its critical infrastructure networks and the retention of manual control capabilities, which were highlighted during the cyber incident of April 18, 2022. During that attack, despite compromises to internal IT networks, the segregated networks and manual overrides allowed electricity, water, wastewater, heating and internet services to remain fully operational without disruption to customers. This design reflects a focus on resilience and continuity of essential services amid cyber threats. The organisation’s ability to maintain service delivery under such conditions underscores its operational preparedness and technical safeguards.
