Stadtwerke Trier [SWT] is a utility and infrastructure service provider that supplies electricity, gas, drinking water, wastewater management, public transportation etc. to the city of Trier.

What sets apart SWT from any  other  utility  and  infrastructure  service provider is its unique  management  model, which is essentially based on cooperation between different business entities creating synergies for efficient ‘Regional Material Flow Management’ toward a higher degree of climate protection.

Towards achieving triple- bottomline sustainability and climate protection,  renewable  resources  and sustainable  technologies  utilisation  are systemic to SWTs work. This model could be an archetypal example of how sustainable utility and infrastructure may be implemented in conventional municipalities around the world.
