Seen from space, our planet should be called Water. Yet less than 1% of all water on Earth is usable for human life. With a growing global population, mounting pollution from organic and inorganic substances, and a rapidly changing climate, that scarcity is accelerating.
Today, only one in two people on Earth has access to hygienic drinking water. Traditional desalination systems only function at coastlines. Importing drinking water is costly, inefficient, and ecologically devastating. The simultaneous global demand for ultrapure water and green hydrogen is rising – faster than any existing technology can address.
GCW exists to change that – everywhere, for everyone.
We envision a world in which clean water is no longer scarce – not in coastal cities, not in arid inland regions, not for industrial processes, not for energy systems. GCW’s technology makes that future achievable today.
Aligned with the United Nations Sustainable Development Goals.
GCW’s work directly contributes to three core UN SDGs:
SDG 6
Goal: Clean Water & Sanitation
Providing safe, accessible drinking water to communities without coastal access.
SDG 9
Goal: Industry, Innovation & Infrastructure
Deploying patented modular technology that operates off-grid and scales globally.
SDG 13
Goal: Climate Action
CO₂-free systems powered 100% by renewable energy, eliminating brine waste.
Our Journey.
GCW German Clean Water GmbH & Co. KG was founded with a singular purpose: to develop technology that makes clean water universally accessible. Our milestones:

Development and completion of the GCW process
In 2010, scientists and technicians from the Berlin CM Institute (Civilizations Matter) began developing a new type of desalination and treatment process.
We wanted to create an alternative to conventional reverse osmosis systems. These conventional systems produce large quantities of brine as a by-product, which in turn has a negative impact on the soil and seabed in many ways. They deprive humans and aquatic animals of their food sources. We are convinced that the reclamation of the destroyed seabed will be as expensive for future generations as the safe storage of nuclear waste.
That is why we have opted for technologies that generate valuable raw materials from harmful residual waste and that can be used primarily within the continent.
From the cradle to the cradle. We have patented the most important principle.
The second consideration was to develop systems that can be shipped and installed in standard-sized containers. They are durable, are manufactured in individual series, can be transported at low cost and are quickly ready for use thanks to plug & play connections. They are designed to be earthquake-proof and can be digitally remote controlled. Our systems are low-maintenance and require little servicing. As a result, no expensive additional investment is required and personnel deployment is low. The systems are operated with renewable energy as stand-alone systems, but part of the energy requirement can also be covered with waste heat from industry. Our plants guarantee a healthy drinking water supply for up to 350,000 people and can be installed directly in front of residential areas as well as in industrial estates.
We attach great importance to the fact that the plants can be used decentrally, as no by-products such as brine are produced.
We are aware that we have to treat the world’s dwindling 1% freshwater resources very responsibly. For this reason, our technology converts up to 95% of raw water, far more than other technologies and processes currently in use. We do not use chemical softeners because we want to produce living water.
International patent application filed for the chemical-free decarbonization process
Our highly purified drinking water is bottled. The premium water has such a high level of hygiene that it is suitable for use in hospitals and healthcare facilities. It can be used in a larger melanche for the production of food (drip irrigation). It is also suitable to be pumped into new water distribution channels without causing contamination or major losses. We develop quality for our customers.
After fourteen years, we have come a long way in our development. That is why we have adapted the company to the new requirements and thus fulfill all UN Development Goals.
The company will have its headquarters in the Elbe Sandstone Mountains of Saxony.
