In America if we saw a massive concrete structure with spray paint on the front in someone’s home, we’d probably turn a blind eye. But in Africa such a piece is the pride and joy of many homes—and more than that, it’s life-saving.

During our most recent trip to Zambia, this woman could not wait to show off her water filter in her home. That filter acts much like a Brita filter, but it will last for years upon years, providing clean water to entire families. The filter takes out contaminants in water that can make people incredibly ill. This woman noticed an impact on the health of her family within weeks of receiving the filter.

So for this Photo Friday, we applaud the big concrete structures. Do you want to ensure more families receive filters or other means to access clean, safe water? Visit nextmillion.org today.
