Plumbing is the system that moves fluids around for heating, cooling, waste removal, potable water etc. Plumbing uses pipes, valves, fixtures, tanks and other things to move fluids around. Plumbing infrastructure is critical to public health and sanitation. [Wikipedia]

Goal 6: Ensure access to water and sanitation for all
Clean, accessible water for all is an essential part of the world we want to live in. There is sufficient fresh water on the planet to achieve this. But due to bad economics or poor infrastructure, every year millions of people, most of them children, die from diseases associated with inadequate water supply, sanitation and hygiene.
Water scarcity, poor water quality and inadequate sanitation negatively impact food security, livelihood choices and educational opportunities for poor families across the world. Drought afflicts some of the world’s poorest countries, worsening hunger and malnutrition.
