Water Usage
The amount of water used in processing depends strongly on the type of processing. Wet fully washed processing of the coffee cherries requires the most fresh water, dry processing the least. Sources indicate a wide range in water use. Recycling of water in the de-pulping process can drastically reduce the amount needed. With reuse and improved washing techniques, up to 1 to 6 m³ water per tonne of fresh coffee cherry is achievable; without reuse a consumption of up to 20m³/tonne is possible.

| India | Semi-washed, wet processing | 3 | |
| Kenya | Fully washed, reuse of water | 4-6 | |
| Colombia | Fully washed and environmental processing (BECOLSUB) | 1-6 | |
| Papua New Guinea | Fully washed, recycling use of water | 4-8 | |
| Vietnam | Semi wet and fully washed | 4-15 | |
| Vietnam | Traditional, fully washed | 20 | |
| India | Traditional, fully washed | 14-17 | |
| Brazil | Semi-washed, mechanical demucilage | 4 | |
| Mexico | Semi-washed, mechanical demucilage | 3.4 | |
| Nicaragua | Traditional, fully washed | 16 | |
| Nicaragua | Fully washed, reuse of water | 11 |

Famous quotes containing the words water and/or usage:
“We then entered another swamp, at a necessarily slow pace, where the walking was worse than ever, not only on account of the water, but the fallen timber, which often obliterated the indistinct trail entirely. The fallen trees were so numerous, that for long distances the route was through a succession of small yards, where we climbed over fences as high as our heads, down into water often up to our knees, and then over another fence into a second yard, and so on.”
—Henry David Thoreau (1817–1862)
“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)
