Digital Enterprise for the water industry

Digitalization for increased transparency and efficiency

From data collection to the use of assistance systems, the networking and integration of subsystems, the decentralization of services, and all the way to the autonomy of entire infrastructure systems: Digitization in the water industry makes possible more efficient and sustainable processes for both new and existing facilities. It involves two levers: the creation of digital twins to optimize processes and the use of digital applications.

The digital twin pays off

The digital twin creates a virtual image of the real plant: The intelligent linking of data from various sources and their processing in a consistent data model helps exploit the full potential of new and existing plants.

Reaching your goals faster and more effectively

Consistent data management and the consistent data model result in the digital twin: an exact, always up-to-date, and virtual image of the entire plant.


The digital twin enables, among other things, simulations to be performed as early as during the engineering phase, comprehensive tests of automation applications, and a realistic training environment for plant operators even before the actual commissioning of the plant. This creates opportunities for process optimization and knowledge management, in this way significantly accelerating commissioning. In addition, efficiency is sustainably increased throughout the entire life cycle of manufacturing and process plants.

Targeted update

Digitalization also pays off with brownfield plants by the creation of a digital image of the real plant that can be linked with imported planning data in a database structure. In this way, the data can be verified, and plant operators obtain an up-to-date digital image of the plant, which is the starting point for comprehensive operations optimization.

Fields of application

Tailored water technologies to specific areas of application

Requirements in the areas of drinking water, waste water, and desalination vary widely. That’s why Siemens offers a selection of perfectly tailored solutions that ensure maximum efficiency and sustainability.

Provide drinking water at a sustainable rate

Intelligent solutions and services from Siemens for planning, engineering, operation, and maintenance are ensuring reliably and sustainably treated drinking water of the highest possible quality around the world. They include process control, automation, and drive technology as well as the power supply for water treatment plants, pipeline systems, and large-scale water networks.

Treating waste water efficiently and reliably

Siemens offers tailor-made hardware and software systems, comprehensive services, and in-depth, specialized expertise for the construction of new or the modernization of existing waste water systems. This ensures safe and reliable waste water disposal via sewer networks and waste water pump stations even in the event of heavy rainfall, as well as the energy-efficient, environmentally friendly, and straightforward operations management of waste water treatment plants.

Desalinate seawater – prevent water scarcity

Seawater desalination is playing an increasingly important role worldwide, especially in regions suffering from growing water shortages. Today over 150 countries are already desalinating seawater. Our customers rely on the energy-efficient process of reverse osmosis. Software, energy supply, energy management, and end-to-end service from Siemens in the areas of design, operation, and maintenance support the energy-optimized operation of desalination plants around the world.

Snowmaking systems

Global climatic changes mean that it snows less and less in alpine areas. This can lead to problems, especially in low altitudes. The smaller amounts of natural snow are often no longer sufficient to guarantee the excellent ski slope conditions that meet the high demands of our time. In order to make optimal use of the capacities of the ski areas, we offer many years of know-how for the automation of snow-making systems. As a leading provider Siemens can offer a comprehensive range of electrotechnical products and automation solutions. Moreover our focus is to provide solutions for energy supply and distribution, drive and automation technology and the implementation of higher-level control systems.


Energy and automation technology for snowmaking systems


Plenty of snow at the right time

Snow falls when the weather is right. But that cannot be controlled. The snowmaking systems equipped by Siemens come into action exactly when the conditions for producing snow are optimal. This means: the production of the “Magic White” begins fully automatically. The operators only have to monitor the process. Automation technology even takes over the saving of resources in energy and water management.

With the higher-level Siemens control system SIMATIC WinCC we do not only offer the visualization of the pumping stations and snow canons, but even more importantly proven features such as load management, building management, integration of snow depth measurements for monitoring the entire ski area.

As a system provider and manufacturer of all components required for energy supply and distribution Siemens has decisive advantages concerning efficiency and reliability of snowmaking systems. On local level programmable logic controllers and touchscreen systems ensure safety and user-friendliness. On general level we handle projects with comprehensive know-how in energy, electrical engineering and automation as well as short software optimized processes.
