eWaterPay: Smart technology to provide sustainable water globally

Winners of the GLOMO award for UN SDG6 at MWC18.

People use mobile money to buy eWATERcredit which is stored on the eWATERtag. The mobile money is sent to the tap using Amazon Web Services MQTT and will arrive at the nominated tap within a few minutes. Using super low bandwidth mobile connections this can be done from anywhere even when there is very poor data connectivity. The system also allows gifting – so anyone, anywhere can buy water credits and they are automatically transferred to a registered tag. If there is no mobile money a smart phone app and NFC transfer with cash be managed by registered water sellers in each village, creating accountability and employment.
