Problem
Water and sanitation are globally recognized as fundamental human rights [1]. Yet, many people around the world do not have access to safe water and sanitation resources [2]. The lack of access to safe water, sanitation and hygiene facilities can have a disastrous effect on the health and well-being of people[1]. In many regions, unsafe water facilities lead to high mortality rates, obstacles to education and a lack of agency [3-5]. In addition, unsafe drinking water can contribute to the spread of diarrhoea, which is the leading cause of mortality around the world [6,7].
