Safe water, everywhere, anytime. This vison is our motivation. We eliminate waterborne diseases and …make the world a better place!
Water disinfection system to provide safe water
Automatic, solar driven water disinfection system for up to 20.000 liter per day pure, disinfected, safe and healthy water. It is working fully solar driven, but can also be used on grid or with a back up battery. It is designed to be almost maintenance free. No chemicals have to be added in. It is designed for easy maintenance and almost zero running cost. It is using high technology to make life safe, to keep it simple and provide safe water. We make the water quality visible, the water quality can be monitored by our App.
GWT is based in Munich. Our solar water disinfection system - we call it INTEWA (intelligent water system) - is automatically delivering safe, disinfected water. We use state of the art technology
Please learn more about our product & projects on this website.
The water is pumped up from a well, a river or connected to a water-tower. It is then automatically filtered and cleaned by filters and a solar driven process. The quality of the water is constantly monitored online, so safe drinking water is guaranteed!
The disinfection cell is automatically reacting.
The water quality sensor (5) is automaticaly regulating the disinfection cell (3) via the internal controll unit (6). In case of drop down of the water quality the disinfection cell is automatically reacting.
All the system data are also send by the integrated GSM module (7) into the cloud. You can see the data on your Laptop or PC and on your Smartphone (App).
Water production volume
The water production volume is depending on the raw water quality and the raw water accessability.
Is the raw water fresh or comming from a public water pipe,
the volume is up to 24.000 ltr per day.
Is the raw water very dirty and the pump has to pump it over long distance, the volume will be less.
For maintenance we need a lemon and a (tooth)-brush, not more. The lemmon is to clean the disinfection cell, about every 4 weeks. The brush is to clean the filters.
We provide a metal filter and a polycarbonate filter. The polycarbonate filter can be replaced easy or even washed.
Of course the system should be kept clean, especially the solar cells.
By default we provide washable stainless steel and ceramic filters. In some cases - depending on the raw water quality - we provide special filters, for example to filter out Arsenic, high content of Iron, Fluoride and others.
The system does not make seawater potable
To make sea water potable, we need an enormous amount of energy. The INTEWA system is not suited for that.
The system needs an additional mineralizer to treat rain water (see products)
Rain water does not contain enough minerals. INTEWA needs a minimum of 40mg Cl-/l. It can be added by a mechanical dosing pump (additional part).
