From the morning shower to freshly washed clothes and the coffee machine - not only our morning routine, but our entire everyday life would be unthinkable without running water. But how does the wet element get into our taps and what happens as soon as it flows down the drain?

From source to tap
The journey begins at the waterworks, where raw water is extracted from rivers, lakes or groundwater. Highly specialised technologies, such as pumps, valves and flow meters, are required for this purpose. Pumps then transport the water to treatment plants, where it is filtered, disinfected and chemically treated. Flow meters monitor every stage of the process to ensure optimal distribution of the water.
  
Once purified, the water enters the municipal supply network. Companies such as American Water Works, the largest publicly traded water utility in the United States, play a central role in this process. Powerful pumps and pressure regulators ensure water is delivered efficiently and reliably to households. Specialised suppliers such as IDEX Corp are also developing innovative solutions to make water transport even more efficient.

Technology in everyday life: water in our homes
In homes, flow regulators and domestic water supply pumps deliver water at a constant pressure to the right places, such as kitchens, bathrooms and upper floors of residential buildings. Heating and cooling systems also use pumps and valves to distribute water for air conditioning. 

Companies such as the Swiss firm Georg Fischer and its Finnish subsidiary Uponor offer customised solutions that promote comfort and sustainability.

Sustainable wastewater management
However, the journey of water does not end after use. It is fed back into sewage treatment plants through a vast network of sewers and pipes, where it is treated again. Check valves prevent wastewater from flowing back into the fresh water system.

Companies such as Ecolab use innovative technologies to make wastewater treatment more efficient while conserving valuable water resources.
