Here is another creation that should help us save more on water. The NoMix toilet is another type of toilet solution that has a urinal in the front half of the bowl. The disposed waste (urine) runs from there to the storage tank. The back half of the bowl is like a conventional toilet, where the solid waste lands and gets flushed away.

Apparently, separating the waste from the urinal system helps wastewater treatment plants gain 80 percent less nitrogen and 50 percent less phosphorous. So in a nutshell, these would help address the fish and wildlife from contracting diseases via water. But this invention needs more improvement if it is to work.

For the waste separation to work most effectively, men needed to sit down to pee. And when women were finished with a urine-only sitting, they needed to do something with their used toilet paper other than flush it. Overall, 60 percent of the users encountered problems of some sort, most notably phosphate precipitate blockages in the urine drainage system. As you can see, it has a long way to go but give the NoMix people credit for breaking the ice.
