Eswatini, which used to be known as Swaziland, was in the news recently with a ceremonial handwashing marking the completion of a project to install hot water handwashing units outside all 92 health clinics across the country. Solar-powered tanks have made it possible to bring hot water to remote places that could never have imagined it, serving 10,000 people each day.

The German company that installed the system noted that while people in the west take hot water for granted, it is a luxury in Eswatini, which is a poor country with high levels of HIV/AIDS and tuberculosis. And that’s true – most of us could not imagine being a nurse for 25 years without having hot water available.
