One of the less well publicized great advances of the past decade is that we have essentially solved desalinization.
Recent advances in the reverse osmosis process mean that capital costs for desalinization capacity have been driven low enough that they can be economically powered by off-peak intermittent power, essentially using reservoirs of fresh water as a grid battery of sorts. The cost of solar and wind in the places that need fresh water are low enough that this can economically replace natural fresh water even in middle-income countries.
Large-scale buildouts are ongoing. We will not need "extreme water recycling" to provide anyone with sufficient water.
Not that it's a bad idea anyway, because it's good for the environment to recycle the other stuff that you pull out of the wastewater stream.
