People are concerned about disinfection by heavy metals and trace substances but still die of cholera. Pathogen removal is of most important concern to assure safe drinking water conditions.

Cost benefits compared to the water price

Compared to the water price in almost all countries you get the cubic meter (1000 liters) tap water for a cheaper price and with a better quality. You can drink the tap water that is produced by the INTEWA system, and you can be sure, that it is safe, because it is monitored online permanetly. The price for public water is higher in most countries than the water disinfected by Intewa. But the public water is mostly not potable. The cost for one cubic meter of residual disinfected water with the Intewa system are – depending on the raw water quality – around 11 cent.


For this you get German standard safe tap water. Everywhere. Anytime


Cost benefits through energy efficiency


The INTEWA system is consuming only 220 W to produce 1000 liters of disinfected potable water.


Compared to this RO is consuming between 3.000 W and 12.000 W to produce 1000 liters of dead (mineral free) water. RO is also producing 50% waste water. This is a problem when wastewater has to be paid for.


UV is consuming 500 W per 1000 liters, but does not provide any residual disinfection. This means that the water can be re-infected again immediately after disinfection.


Boiling is using the most energy, it is about 92.000 W per 1000 liters.

Business model water kiosk


There are several good business models, that provide a quick pay back period. One of them was developed by a team of the Thammassat University in Bangkok and won some prizes at several international business plan competitions. Here is the model for the water kiosk:


The investment cost are including the shop.


 Business model:



 decentralized water supply

Dezentralized water supply is one of the new world decentralized concepts, that will change our infrastructure, like the decentralized energy supply (by solar roof top systems) or the decentralized data and knowledge supply (Internet).

Creating dezentralized water supply and disinfection structures safe lots of money.

  • There are no pipes needed to be built in remote areas
  • The remote villages can be connected
  • Redundant systems can provide safe tap water out of every water tap
  • All systems can be controlled central. Maintenance cost are saved
