Clean water
without boundaries
without boundaries
Our mission starts with a simple goal: ensuring access to clean water and a clean environment for everyone. The reality, however, is that modern water treatment depends on chemistry. For over 150 years, chemicals have played a critical role across drinking water, wastewater, and industry. The challenge is not the chemistry itself, but how it is delivered today. Water of people and industries rely on complex chemical supply chains—trucks, storage, hazardous materials, and associated carbon emissions. This creates dependency, risk, and environmental impact.
At CIWI, we believe the solution is not to remove chemistry, but to rethink it.
By producing water treatment chemistry on-site, we keep what works while removing the downsides—making water treatment safe, reliable, and sustainable.
Let’s choose Chemistry over Chemicals
what we do
Moving chemistry out of the supply chain and back into water treatment.
Our background story
Global projections by the UN show that up to 40% of the world could face water shortages by 2030. Ensuring reliable water treatment is therefore becoming increasingly critical. Yet today, the most visible sign of a treatment plant is not the water itself.
It is the steady procession of tanker trucks, hauling in tons of corrosive, carbon-intensive chemicals.
Early on, through insights from Invest International and field exposure in Ghana and West Africa, we encountered what this dependency looks like in practice: treatment plants unable to operate reliably, not due to a lack of water, but due to limited access to the chemicals required for treatment.
This triggered an exploration of alternative approaches, including conventional electrocoagulation, aimed at enabling more independent operation. While promising in concept, these systems proved difficult to scale and operate reliably in practice.
Further academic work at TU Delft and IMD showed that this challenge is not limited to a single region. Across Europe and other parts of the world, water treatment processes still depend heavily on complex and vulnerable chemical supply chains.
Building on this understanding, CIWI was founded at YES!Delft. Together with Prof. Doris van Halem, a new approach was developed: a scalable, robust technology that enables the on-site production of coagulants for water treatment.

Why we do it
Clean water should not depend on location, infrastructure, or chemical supply. Yet today, it does, creating inequality and fragility in systems that should be reliable.
How we do it
We believe that access to clean water starts with removing dependence on chemical supply chains, bringing treatment closer to use, and making systems more reliable and independent.
What we do
We build systems that produce essential water treatment agents on-site, enabling drinking water plants, wastewater facilities, and industry to operate with full control over their chemistry.
Take control of your water by taking control of the chemistry.
Ensuring reliable access to clean water, everywhere
Clean water should not depend on location, infrastructure, or the availability of chemicals. Yet, today, that is often the case. This dependency makes systems vulnerable and unnecessarily complex, whereas water treatment should be reliable and accessible to everyone, everywhere in the world. CIWI believes that this can be done differently by fundamentally rethinking water treatment and bringing it closer to the user.
