Overview

In 2015, 71% of the global population (5.2 billion people) used a safely managed drinking-water service – that is, one located on premises, available when needed, and free from contamination. Currently 423 million people still take water from unprotected wells and springs. As inappropriately managed water services expose individuals to preventable health risks, we are developing a solution to improve the drinking water quality for existing community water sources.

Our Solution

Our Solar Water Alternative Purifier and Charging System (SWAPCY) is equipped with a 20 μm sediment filter able to remove sand, algae, rust and suspended particles. Furthermore, two integrated antimicrobial ultrafiltration membranes remove aluminium, ammonia, iron, active chlorine, sulphates, nitrates, bacteria and coliform bacteria resulting in a total daily filtration capacity of 300 litres (2.2L per individual across 135 people). Other components include 8 USB mobile phone charging ports (charging 80 phones per day), LED lighting for operation at night, as well as the possibility to incorporate a Raspberry Pi system. We aim to have a first working prototype by the end of 2018.
