Not nothing or nominal, but cheap enough that it is feasible, and about the same as other options. We also recycle 80% of the water, first in the world. The second-place country does 15%,

Recycle to the point of making it potable again, or recycle for other uses, like agricultural? If the former, that is truly a wonderful achievement. (Even the latter is pretty great, though!)

Even the recycled wastewater is potable, but it is use for agriculture to satisfy people's sensibilities.
