No difference between ...

No difference between traditional sanitation and defecation in the open air.

Demonstration:

1- A person defecates in a latrine connected to an excrements storage tank.

2- A truck emptying excrements from the storage tank .

3- Vacuum truck transports the excrements to a STEP sewage plant.

4- The same excrements input of the WWTP find themselves on the output of the STEP and composting stream.

5- The same excrements are scattered on the floor of sewage farms.

Synthesis.

The current infrastructure pass to the place of excrements defecation to the place of storage on tarps in expectation of a possible palliative treatment: Weather, rain and wind, which disperse in the environment, spreading in agricultural land. Urinary pollution was rejected as it is in the closest natural hydraulic medium. Nowhere appears a trace of any effective treatment of their reduction, elimination.

This principe is only the management of droppings which closely looks like the configuration of defecation in the open air .

Conclusion.

The grouping of excrements should be banned, it is an ecological, economic and biological disaster.
