The Future of Urine Diverting Toilet Technology

And the C-Head toilet system

Looking to the future, some aspects of urine diverting toilet technology are clearly promising. Separating urine from the solid waste reduces the time and cost of converting human solid and liquid waste to a safe, recyclable product. The Novaquatis urine source separation project at Eawag has developed a highly efficient wastewater treatment plan. It is based on using a slight variation on the same type of plumbing infrastructure that we use today for standard wastewater treatment systems. These systems do have some drawbacks in that they can be expensive, and do require ongoing maintenance of the grid which includes lift stations (counter measures to the ironclad plumbing axiom that “poop flows downhill”) and processing plants. In addition, they require all users in the area to use a specific type of urine diverting toilet and a dedicated plumbing system. Urine diverting toilets have a good reputation based on theory because most people who understand them think they are a good idea. That is not the same thing as thinking that they actually want to own one or learn how to use one. People are slow to change habits, especially toilet habits.
