PWN supplies drinking water to over 800,000 customer connections in the province of North Holland. The company is well aware of the rise of digital water in the context of environmental challenges and technological opportunities and is in the process of digitalization itself. Central aspects of this development for PWN are the creation of a data lake and a digitalization vision and roadmap. However, the data lake and associated data flows have not been fully made into an integral part of PWN’s processes yet, and the finalization and implementation of the vision and roadmap will take time as well. The current state of development, the groundwork that has been laid, and the ambitions of PWN make an excellent combination both for feeding requirements and use cases into the creation of water data spaces and providing test beds for their implementation and testing.
