Over 2 billion people in the world do not have access to clean drinking water, including 450 million children
This is mainly caused by the lack of an affordable and adequate infrastructure to guarantee a continuous treatment, distribution and supply.
This often leads to dire circumstances: serious illnesses due to contaminated drinking water, low livelihoods and the loss of human dignity.

Q4W is a smart water treatment system that provides real-time analysis and monitoring across the water cycle. Using advanced sensors, it detects issues, supports remote access, and improves utility efficiency
K4W also addresses non-revenue water challenges, driving revenue growth and optimizing the water cycle.

By treating water smartly and efficiently, clean drinking water becomes accessible to everyone
Q4W (Quality for water) has developed an innovative technology to treat contaminants water efficiently and sustainably. The technology is based on simple processes to provide clean drinking water
The universal water treatment technology can be at minimal low cost. The technology filters the actual contaminations in the water. Water that does not contain any chemical substances, bacteriological parameters, particulate turbidity and microorganisms goes directly to the water supply. This makes water treatment cheaper and clean drinking water affordable and available for all in the world

Quality level and monitoring
The water quality is digitally measured at the source by Q4W technology. It is determined whether the water needs to be treated, and treatment method is determined
Directly usage clean drinking water
Clean water goes directly to the water supply. So no unnecessary treatment. This saves money and energy
Treatment contaminated water
Contaminated water is treated, based on the type of contamination before it goes to the water supply. The treatment method is eco-friendly without generating wastewater.
Usage
To strengthening system sustainability, reliability and continue clean drinking water supply, the user pays inexpensive fees for the water via cashless payment or using a mobile app connected to a smart meter with backup at home and/or business
Partners
Q4W partners with companies, municipalities authorities, research institutions, consultancy firms, various businesses and financing institutions. Our Technology can help resolve issue of non-revenue water, improve efficiency, flow accuracy assurance, remote monitoring plant utilities and water supply

The Ghana GA South project
Together with the local partner and landowners, we have determined the preconditions for a sustainable implementation of safe drinking water installation. The project takes place in Adjen Kotoku GA-South in the Great Accra province near the Densu River. The Densu is a 116 km long river that originates in the Atewa region and flows into a lively swamp. With the Q4W drinking water technology installation we ensure a continuous supply of 208m3 of clean water per day. 330,000 people can drink from this per day
