People each put 300+ liters of greywater through the sewer system? Seems a tad bit high.

- XR0CSWV3h3kZWg 9y agoUS puts water consumption per capita at 2,842 cubic meters per annum. (2,842 cubic meters in liters)/365 = 7.7k liters.
- Johnny555 9y agoThat's all water use, not household or office use that could be used for this purpose. For example: Meat consumption accounts for 30 percent of the American figure, and sugar consumption is responsible for another 15 percent https://www.scientificamerican.com/article/graphic-science-how-much-water-nations-consume/ https://www.scientificamerican.com/article/graphic-science-h...
- jdmichal 9y agoI'm guessing that number is for all uses. Obviously, as being discussed, industrial and agricultural water uses would not be eligible. The USGS [0] estimates 23,800 mega-gallons per day for domestic use by 268 million people. This is about 89 gallons or 336 liters per day per person.

- hwillis 9y agoI took that figure from the USGS per capita household water use[1], which was 300-380 liters per day. Watering plants may make up as much as 20% of that but the biggest culprits are toilets and showers. This report[2] directly measured 1000 households and found daily direct water consumptions from 456 liters to 1815 liters(jesus).
