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.

| 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 | |

| 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:
“I believe that water is the only drink for a wise man: wine is not so noble a liquor; and think of dashing the hopes of a morning with a cup of warm coffee, or of an evening with a dish of tea! Ah, how low I fall when I am tempted by them! Even music may be intoxicating. Such apparently slight causes destroyed Greece and Rome, and will destroy England and America.”
—Henry David Thoreau (1817–1862)
“Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
