DRY ECOLOGICAL LATRINES
Excerpt from the publication "Sanitario Ecológico Seco" (Dry Ecological Latrine)
The dry ecological latrines have two chambers (A and B),
they use no water, |
and separate urine from fecal matter by means of the ecological toilet.
|This is the way you construct a dry ecological latrine.|
The latrine functions with a mix of 3 parts of soil and 2 parts of lime or ash|
(you can also use wood chips).
|The latrine is prepared with a layer of this mix.|
The ecological toilet separates urine from feces, and the urine is sent |
to an underground deposit filled with gravel.
|After each use, a small amount of soil is dumped into the chamber.|
The chamber needs to be maintained in optimal conditions every so often|
(add a cup of lime twice a week).
After a period of use, the A chamber rests for at least 6 months, |
while the B chamber is being used.
After the B chamber has been used for 6 months or more,|
the humus in A chamber is removed and spread in the field.
|Ventilation of the chamber is very important.|
The dry ecological latrine is the practical solution to
sustainable human waste management.
"Cleaner is not he who cleans more, but rather he who dirties less."
