How might we WHAT for WHOM in order to CHANGE something?
Deliver clean safe drinking water to people wherever they live so they have plenty of water for drinking, cooking and washing that won’t make them sick
- filter local water to remove impurities and germs to make it safe for drinking
- filtration – screen out tiny particles of dirt, bacteria
- boil or distill water to kill germs that could cause sickness
- vaporization, condensation – only the water in gas form can cross into the container of “distilled” water leaving behind any other material
- bottle clean water and transport it to those in need, recycle the bottles or reuse for other purposes
- plastic forming – manufacture empty bottles and caps that can be sealed when they have been filled with safe water to keep the water inside clean until it is ready to use.
- flow, pump, treatment, retention, filtration
