So which technology wins? All of them, depending on your budget and how many germs annoy you. Medium-pressure is for big cities with big electricity bills. Low-pressure is for efficient plants that love spreadsheets. UV-LED is for futurists who want to drink their own shower runoff.
What makes UV the undisputed champion for Class A reuse is simple: it kills things without adding anything gross. No chemicals, no smell, no taste. Just light. And as any germ will tell you, the most terrifying thing in the universe is a very bright, very focused bulb. Now go drink some recycled water—it’s cleaner than the coffee you’re holding, and likely tastes better.
