Water For People is a global nonprofit that helps people bring clean water and sanitation solutions to their communities for generations to come. Available online. The share of the world without access to improved water sources has declined in recent decades. Research is ongoing to determine the full potential and optimal scales for such interactions between water and electric grids but could offer a way to optimise existing infrastructure for both utilities. Unsafe water is one of the world’s largest health and environmental problems – particularly for the poorest in the world. Clean water is a basic human right and should be accessible to all communities. 1. Our rivers, bays, lakes, and streams are vital to a healthy environment and a vibrant economy, and provide endless opportunities for swimming, fishing, boating, and other recreation. Clean water’s share does not only depend on how many die prematurely from it, but what else people are dying from and how this is changing. 6% of deaths in low-income countries are the result of unsafe water sources. Leakage of water from ageing infrastructure wastes more of this precious resource, yet the costs of replacing that infrastructure seem insurmountable. By 2015, this had nearly halved to 666 million. Sanitation – unsafe water sources, poor access to basic handwashing facilities and unsafe sanitation are often linked. 785 million people in the world live without clean water.
