Today, some 785 million people lack access to safe water and 2 billion people lack access to toilets, according to water.org. Of these, 156 million city dwellers do not have efficient, affordable connections to water services and 700 million live without improved sanitation, according to the United Nations. The situation is causing serious public health concerns, particularly in the wake of the COVID-19 pandemic, along with significant environmental challenges. Clearly, expanded access to safe water, sanitation, and other municipal infrastructure is an imperative of these times. But the cost and complexity of these projects are such that innovative, market-oriented, long-term solutions are needed.
