save!


LAUFEN, 2019

EOOS, Eawag and LAUFEN have developed a pioneering urine-diverting toilet that revolutionizes the user interface for sustainable urban water management. save! is an evolution of the pioneering Blue Diversion Toilet, which was developed by EOOS and Eawag and supported by a grant from the Bill & Melinda Gates Foundation.

The product’s key innovation is a “Urine Trap” invented by EOOS Design, which directs urine towards a concealed outlet using only surface tension. Laufen applied this concept to a new toilet design featuring a ceramic bowl that is optimally shaped to guide the water flow. The interface’s easy maintenance, low-tech, hidden innovation ensures it is indistinguishable from any other high-end WC. save! represents a new format for a familiar product that is business ready and could play a key role in the future of wastewater management.
