Maybe its time to start thinking retrofit of parallel systems for drinking vs. irrigation water....we do have some of that out here in the West....Uunfortunately this will only get worse as more and more aquifers are drawn down.....I do agree with you about capacity though....more reservoirs is GOOD.

Greywater recycling systems make sense in a number of areas.
But I have absolutely no idea how it would work in densely populated urban communities,
most of what I've read about is applicable to individual homeowners and locations in more rural regions.
But perhaps there are variations of the concept that I'm unaware of.
