Waterless

"RP to Export Waterless Toilets," an Inquirer goes. My first hunch was: Oh My God. What came to my mind was the plastic bags of shit flying along the riles (My father used to work for the PNR and I heard horror stories on this) and just anywhere else. It turned out to be ceramic bowls manufactured by Ecosan. Theya re more popularly known as double-vault urine-diverting toilets.

The basic principle of this toilet is to separate urine and shit. Urine, which is almost completely free of pathogens, is diverted through the use of urinals or special pedestals or squatting slabs and then collected. Feces are collected and stored in a secure vault where pathogens are broken down. If the feces are kept dry, pathogens die within a short time as the feces undergo decomposition (composting), a biological process in which bacteria, worms and other types of organisms break down organic substances to make humus, an excellent soil conditioner.
