Produce your own drinking water from rainwater with the Drop2Drink unit
Rainwater is clean and free. We make it safe.
Rainwater is an excellent and free water source. You only need to collect it. The Drop2Drink unit can then filter your rainwater into safe drinking water that meets Dutch and Belgian drinking water quality standards.
The Drop2Drink unit is an intelligent water purification system that converts rainwater into microbiologically safe drinking water, directly on-site and exactly when it is needed.
The system combines multiple filtration steps in one compact unit:
- Coarse prefilter (90µ)
- Microfiltration (25µ)
- Activated carbon filtration
- Ultrafiltration (UF membrane; 0.02µ)
- UV disinfection (backup)
This combination ensures high reliability and additional microbiological safety.
Dashboard
The Drop2Drink unit always comes with a dashboard that provides the user with insight into water consumption, pressure levels, system performance, maintenance, safety, and settings.
The Drop2Drink unit performs periodic self-maintenance automatically, which can be adjusted within the system settings. Wherever possible, maintenance procedures are carried out automatically.
Maintenance
The prefilter and ultrafilter are automatically maintained by the system.
Maintenance of the Drop2Drink unit consists of replacing the microfilter and activated carbon filter every six months.
The self-cleaning prefilter should be cleaned once a year, either manually or in a dishwasher. The ultrafilter typically requires maintenance once every four years, which is carried out by an installer.
The partner from whom you purchase the system will offer you a maintenance package.
Estimated annual maintenance costs are approximately €130 to €260, depending on the local situation and selected partners.

Rainwatersystem with the Drop2Drink unit
A rainwater system with the Drop2Drink unit is very simple. You collect the rainwater in a tank with a pre-filter. In the tank you attach a powerful pump that ensures sufficient water pressure. The Drop2Drink unit does the rest: when the rainwater enters, it is immediately purified, so that the water can be safely distributed to all taps throughout the building.
This looks like this schematically.
Applications
The Drop2Drink unit is suitable for:
- Homes and apartments
- Hotels and recreation accommodations
- Cattle breeding
- Food industry
Safe water
The Drop2Drink unit was tested by the World Health Organization (WHO) at KWR Watercycle Research Institute, a WHO collaborating centre and one of the most qualified water research centres in the world. The test results were excellent.
| Microorganism | Log10- reduction | Proc.removal |
| Bacteria | 8,2 | > 99,999999% |
| Bacteriophage type 1 | 5,7 | > 99,999% |
| Bacteriophage type 2 | 3,7 | > 99,9% |
| Protozoa | 8,2 | > 99,999999% |
For the European subsidized VIDA project, the Drop2Drink unit was tested at two companies in the food sector in 2020 to demonstrate that purified rainwater can fully meet the requirements for drinking water in accordance with the Dutch Drinking Water Act. That has been carried out successfully. With the Drop2Drink unit you can therefore rely on the safety of the purified water.
