Overview
Founded in 2017 in Ghent by Jacob Bossaer and Pieter Derboven, BOSAQ develops off-grid water purification technology for remote and resource-constrained environments. The company's systems are designed to operate without connection to centralized infrastructure, making them applicable in developing markets, disaster response, and industrial off-grid settings.
CEO Jacob Bossaer has an unusual background that informs the company's mission: he worked as a water engineer in Antarctica, where the challenge of producing clean water in extreme, infrastructure-free conditions shaped his approach to decentralized purification.
BOSAQ sits within the broader Belgian water technology cluster, alongside companies like Shayp and Waterleau, which together form a notable concentration of water innovation in the country.

In the news
- Building water autonomy starts with building the right partnerships. 💧 Indonesia faces very different water challenges across its regions, communities, and industries. That means there is no single solution that can simply be copied from one location to another. Over the past few weeks, BOSAQ has been exploring how our decentralised water solutions and experience can contribute to Indonesia’s long-term water ambitions. A key part of that is working locally. Our CEO, Jacob Bossaer, together with Anthoni Tarigan and Rama M., met with
- Kenya is growing. Its water infrastructure needs to grow with it. 💧 Last week, we had the honour of welcoming H.E. Ambassador Hon. Amb. Joash Maangi, MBS, LLB, Dip. KSL, Doc Juris, Ambassador of the Republic of Kenya to Belgium, to BOSAQ. Accompanied by Dr. Eng. FLORENCE KIBURI, Agriculture Attaché, and Mr. Ahmed Muktar, Second Secretary, the Ambassador visited our facilities to explore how BOSAQ’s decentralised water treatment solutions could contribute to Kenya’s growing water needs. During our discussions, the Ambassador
- Building stronger economic ties starts with the right conversations. On 5 October, BOSAQ was proud to partner in convening the Belgium–Moldova CEO Working Dinner in Brussels, held in the presence of H.E. Prime Minister Vasile Tofan of the Republic of Moldova. The closed-door dinner brought together senior business leaders and institutional stakeholders for a focused discussion on how Belgium and Moldova can deepen cooperation around trade, investment and long-term economic development. With Moldova moving closer to the
- Modular or turnkey? The better question is: what does your project actually need? In industrial water projects, both approaches can deliver the required water quality, fit within site constraints and integrate with existing infrastructure. The difference is mainly in how the project is built, delivered and allowed to evolve. A turnkey approach can make sense when the scope is well defined and you want one party to coordinate the complete system - from engineering and integration to commissioning and performance. A modular approach
- Almost 1 in every 4 litres of water in Europe's pipes is lost, mostly through leakage. That was one of the figures European Commission President Ursula von der Leyen highlighted in this week's State of the Union, a speech built around one idea: a stronger, more independent Europe. Less dependent on imported fossil fuels. Less exposed to fragile supply chains. Better prepared for a hotter, more volatile world. Water belongs on that list. After a summer in which 660,000 hectares burned, around 12 million tonnes of crops were lost
- Charity is easy to measure in euros. The real impact lies in what those euros continue to do long after they're given. Water Heroes is an independent NGO founded by BOSAQ that works to provide safe and clean drinking water to vulnerable communities that cannot afford these solutions themselves. It raises funds through donations, partnerships and contributions from supporting companies. BOSAQ contributes by donating 10% of its profit to Water Heroes. On 5 September, the United Nations marks the International Day of Charity and for
- A pilot doesn’t only produce water. It produces answers. It is where assumptions get replaced by operating data. Scale off a spec sheet, and you find out on commissioning day that your influent doesn’t behave as the datasheet assumed. At that point, the fix is expensive. Together with Aquafin, we designed and built two pilot units for two very different water streams, as part of the B-WaterSmart Project living lab in Flanders. Q-Drop Vikos – 1,000 litres per hour. Membrane filtration and polishing. Pretreats domestic wastewater
- Under what conditions were those numbers achieved? It's the question that most efficiency claims aren't built to survive. When you compare industrial water treatment systems, the numbers look impressive: → Higher recovery → Lower energy consumption → Lower chemical use → Smaller equipment All relevant. All achieved at one design point. Your plant doesn't operate at one design point. Feedwater quality changes. Temperatures fluctuate. Production demand varies. Membranes foul. Equipment ages. And pushing one parameter harder affects
