Doesn't really hack it at the price tag, plus there will be running costs. Maybe $1000 might make it interesting, but otherwise no.

There are plenty of folks who just plumb gray water directly to toilets. It's places like swimming pools where things get iffy (and I'm not sure I'd go for that as a "non-potable" use).

If the price were lower I would consider it. The city I live in charges for water usage and sewer. My complaint about sewer charges is that when I water the grass or wash a car I still get charged as if the water went in the sewer.

Haha, that pretty much useless video... and “affordable”??? Silliness. The concept makes sense but the cost must fall to a quarter or less, especially since extensive custom plumbing is required. But kudos for an article that, for once, actually includes the typical payback calculations! Well done on that.

Cool enough idea, I wouldn't worry about reusing it's output in my pool. I would, however, balk at the untold thousands it would cost me to trench lines under my concrete slab from my 2 baths and laundry to the unit. Odd this thing comes from the Netherlands, water isn't a particularly scarce commodity there!

Might be OK for the rare home owner who lives off grid and only uses rain water.

The unit is shown installed in a high end house where it would reasonably be. As such, it doesn't make much of a dent in water usage. Desert communities used to have fixed cost or one time payment water as a move in incentive. This led people to put in trees and sod and use evaporative cooling.

Love the concept, but the use of "Hydra" in the product name seems a little unfortunate (see https://en.wikipedia.org/wiki/Lernaean_Hydra): "Hydra, is a serpentine water monster in Greek and Roman mythology. [...] It had poisonous breath and blood so virulent that even its scent was deadly." lol

Even with roughly half of our rural two acre property in lawn and an automatic sprinkler system, our annual costs are well below that. I'll have to investigate whether any gray water recycling systems for RV's are available. That would be great for back country trips.

@JeffK They do exist, i.e. see: https://www.instructables.com/id/Showerloop/
