The global need for safe and healthy drinking water
A Sustainable Solution to Convert Tap Water Into Safe and Healthy Drinking Water


- OeauO -

Clean, safe and healthy drinking water that tastes well: our lives depend on it. While substantial progress has been made in increasing access to clean drinking water and sanitation, billions of people, mostly in rural areas, still lack these basic services.

Worldwide, one in three people do not have access to safe drinking water, two out of five people do not have a basic hand-washing facility with soap and water, and more than 673 million people still practice open defecation.

The COVID-19 pandemic has demonstrated the critical importance of sanitation, hygiene and adequate access to clean water for preventing and containing diseases. Hand hygiene saves lives. 
According to the World Health Organization, handwashing is one of the most effective actions you can take to reduce the spread of pathogens and prevent infections, including the COVID-19 virus. Yet billions of people still lack safe water sanitation, and funding is inadequate according the United Nations


Dutch r&d company Sterwater International has developed OeauO, a patented countertop appliance for domestic use that purifies tap water to the highest international standards.The OeauO home appliance features the unique Safe Water Capsule, harbouring The Safe Water Filter, a filter that clears tap water from chlorine, bacteria, micro-organisms and microplastics.

OeauO is a sustainable brand of premium quality filtered drinking water. Wherever you live, in India or in Spain, filling your glass with pure, crystal clear water will become as easy and affordable as brewing a cup of fine coffee.

Facts and figures
Five-liter plastic drinking water bottles close-up, soft focus

According to the World Health Organization, in 2015 only 71% of the global population (5.2 billion people) used a safely managed drinking water service, free from contamination. Meanwhile, the consumption of bottled water has exploded, with people in the UK alone consuming 2.6 billion litres in 2014.

Most plastic bottles end up as waste in our environment, contributing to the ocean’s 269.000 tonnes of plastic soup, endangering nature, wildlife and human health.

In 2017, scientists found that 83% of the tap water worldwide is polluted by microplastics.

With OeauO, Sterwater International answers the urgent demand for safe and healthy drinking water and the reduction of plastic waste. Our sustainable solution to purify tap water offers our customers easy access to safe and healthy drinking water, right in the comfort of home.

Our Story
Our-story 2

Sterwater International was founded by Maurice Visser, industrial engineer in biochemistry. Maurice Visser comes from a family of seasoned entrepreneurs, starting in 1892 with his great-grandfather, who created the family business in Oud-Beijerland. The company produced canned and frozen foods in family-owned factories, trading all over Europe through their own distribution network.

In the sixties, the company created the iconic Suzi Wan product line, focused on Asian food. In 1980, after enjoying spectacular international growth, the Suzi Wan company was sold to Mars Inc.

In the last decades, the company has focused on developing sustainable concepts for filtering water streams.

Today, backed by a solid track record creating innovative water filtration technology, Sterwater International develops water filtration products for the consumer market.
