Where it works

Especially for rural areas the INTEWA System is providing important benefits.

Rural Areas often have no access to public water, and the piping costs would be very high. Sometimes the energy supply is not stable or even not available. Therefore people living in rural areas have often no access to disinfected.

The INTEWA system is providing safe, disinfected water in rural areas, where there is no energy available. No chemicals have to be bought and added in, because the disinfectant is produced inside the system out of the minerals in the water itself.

Benefits for rural areas:

Fully solar driven water disinfection and operation
Automatic disinfection without adding chemicals – the disinfectant is produced by an electrolysis cell out of the minerals in the water
Automatic adjustment of chlorine production through permanent monitoring of the water qualitiy
Remote monitoring via integrated GSM module
Alarm message to smartphones or control center
Automatic residual disinfection accordiung drinking water laws
