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.
