Occupancy-Loaded Greywater Reuse Benchmarks: Sizing, Timing, and Real Yield
Every greywater guide I read says the same thing: 'a typical family of four saves this many gallons' or 'you can cut your water bill by half.' Then you move into a two-person apartment, and the math falls apart. The truth is, benchmarks for greywater reuse don't sit still. They stretch and compress with occupancy load—how many bodies use your showers, sinks, and washing machine, and when they do it. This article gives you the real numbers, the ones that shift, and shows you how to make them fit your place. We've been through this cycle enough times to know the pattern. The numbers lie because they assume a steady state that never existed. But here's the thing: once you start measuring your own flow, the lie gets exposed fast. And that's when the real design work begins.
