We were very surprised when we learned that the toilet that brings together our odia and disappears was the subject of scientific research. We could accept artistic research to improve the aesthetic form. But science made us laugh first. However, as we delved into the subject, we saw that it was not joking.

The study has been conducted in Britain and the results have been collected in an ambitious report. The study has a concrete and understandable goal: to limit the minimum amount of water needed to clean the toilet hole once released. In other words, behind this curious study was not to waste precious water.

Toilets currently used in Britain use 9 liters of water per discharge. According to the new standards established, toilets installed from 1993 will have a maximum of 7.5 liters of water in discharge. The study indicates that with the current design, 6 liters of water would be enough to carry up to the most sticky time. With small modifications (improving the distribution of water inlets and reducing the amount of water that can contain the S-shaped pipe used to eliminate odors) would be enough 4 liters of water.

The sessions to try the bathrooms have been curious. In paper sessions, 12 wrinkled needles were thrown one by one into the bathroom and then water was discharged. In order for the toilet to be suitable he had to carry the papers in four of the 5 discharges. Non-absorbent material of 1.08 density and 43 mm was used as a mortar.

This Swedish bath only needs 3 liters of water.
