Sanitation here refers to the hygienic disposal or recycling of waste. Often this waste is in the form of wastewater or waste water, any water that has been negatively affected in quality by human influence. This can be W (toilet waste and greywater) or industrial waste.

For solid municipal waste and associated recycling, see Waste management.


Using catfish to eat sewage

Based on comments posted by Chriswaterguy (under the username Singkong2005) to Wikipedia:Talk:Catfish#Using catfish in septic tanks.)

Catfish are used in septic tanks in Indonesia, to eat the waste and prevent the tank from filling up with solids too quickly. I can't find a better source, so I'll just offer these links for now, and hope that someone comes up with a source. I might try and research and (co-)author a journal article on it this year (2007), which would then be a valid source.

Chriswaterguy's comment: An Indonesian's comment on catfish in septic tanks

The Indonesian Wikipedia article on catfish mentions that freshwater catfish are used to remove impurities from water; it states that catfish used in the way must be cleansed before eating, by being placed in flowing water. (The article doesn't state how long for, or just how much this improves the taste & safety).
