Not true. There are multiple grades of water that are used in a semiconductor plant and not all of it needs huges amounts of treatment (like process cooling water). However extracting the heat out of that water tends to cause a lot of evaporation, especially in high temperature climates...thus a lot of makeup water. Some fabs have a goal of 100% recycle, but that is not going to happen. Even small fabs tend to use and discharge hundreds of thousands if not millions of gallons per day. https://www.oregonlive.com/silicon-forest/2017/08/intel_water_recycling_project.html https://www.oregonlive.com/silicon-forest/2017/08/intel_wate... Intel in the Portland area uses over 2 billion gallons of water in a single year. Even with their latest recycle plant online, that only cuts their usage by half.
