Pay for water. Not for the infrastructure.
BOSAQ finances, installs and operates the water reuse system on your site, while you pay only for the water you use.
How it works
-
01.
Assess
We assess your water sources, consumption and water quality needs.
-
02.
Install
A Q-Drop unit arrives ready to connect. Plug & flow.
-
03.
Operate
We manage the entire system, on-site and remotely, around the clock. Advanced monitoring, sensors and an AI-driven predictive maintenance system detect potential issues before they impact your operations.
-
04.
Pay per m³
One price per cubic metre, everything included. That's the invoice.
What's included
Every Circular Water-as-a-Service contract includes our full Diamond package. It comes in two parts: the treatment system installed on your site, and the Diamond service that keeps it running. Both are standard, in your price.
The system
- Q-Drop unit Owned by BOSAQ for the full contract.
- Installation and commissioning Connected to your existing water infrastructure.
- BOSAQ IQ The digital brain of every Q-Drop. It spots what is off and corrects it itself, using as little water, chemicals and energy as possible.
The Diamond service
- Full operation We control your installation remotely, continuously and proactively.
- 24/7 availability Day and night, every day of the year.
- On-site support Our engineers are always ready to provide on-site support.
- Dedicated spare parts A stock of critical parts ready for your installation, so repairs happen fast.
- Your own dashboard Follow performance live. We run it, you see everything.
- Service tickets Report an issue any time.
Why companies choose it
-
Preserve capex for your core business
Water reuse no longer has to compete with new production lines for budget and manpower.
-
We guarantee performance
BOSAQ owns and operates the asset, so we ensure compliance and uptime, with a 96% minimum uptime.
-
One predictable price
A fixed price structure designed to minimise OPEX over the full contract period.
-
Less freshwater use, better ESG
Circularity replaces single-use water.
DESOTEC sells filtration as a service. For its own water, DESOTEC chose the same model.
DESOTEC reactivates spent activated carbon at its sites in Roeselare, a process that uses large volumes of water. BOSAQ treats effluent from Aquafin's wastewater plant into high-quality process water that replaces DESOTEC's tap water use. The project is developed together with the Flemish Environment Agency (VMM).
The impact
-
15 years
Service agreement
-
~100,000 m³
Reused every year, about 40 Olympic pools
-
Tap → reused
Treated effluent replaces drinking water in the process
In their words
At DESOTEC, sustainability is at the heart of everything we do. Our mobile filtration solutions are inherently circular. Integrating BOSAQ's water technology allows us to extend this closed-loop approach to our internal processes, ensuring that our operations embody the sustainable impact we deliver to our customers.
Circular Water-as-a-Service is one of three ways to deploy a water reuse system. Together, we select the model that best matches your budget, payback requirements and long-term water demand.
