My house is on a septic system. Recycled urine is why my backyard grass is striped with intense green sections! Natural bacteria process the urine too.
“Experts” says we should collect urine, separately, and process for use as a fertilizer.
Urine has lots of nitrogen and phosphorus—a problem as waste, great as fertilizer.

I live in an older home, on a large lot – hence, on a septic system. Our neighborhood has neither sewer lines nor natural gas lines. The latter will never be installed as gas is being phased out.
From the story it sounds like they are proposing a point source diversion system at each house, with new fixtures and piping, diverting urine into a yet to be constructed 2nd sewer system. That sounds expensive. While the fertilizer may be sold its not clear this would fund the operation. For example, I previously lived in a town whose wastewater processing systems composted fecal matter into fertilizer (not for human food crops). They also ran a power station fueled by dry trash – burning trash into power and selling the ash for cinder block manufacturing. Neither made enough to fund their operations by themselves.
