Indeed. If you do only the drinking water, 2L per person per day for 20 million people is only 10566000 gallons or 132 football fields.

- MayeulC 7y agoAnd for those who wonder like I did, I counted around fifty of those on that page: https://www.nycgovparks.org/facilities/football https://www.nycgovparks.org/facilities/football
- ebg13 7y agoOk, but if you use those then you don't have anywhere to play. I think more importantly, 132 football fields is about the same as the total floor area of the Pentagon.
- taneq 7y agoInstall the solar panels over the football fields as roofing.
- MayeulC 7y agoIf you can afford it, and/or land/actually mounting the panels is the most expensive part, I'd recommend to install photovoltaic panels instead, though, as they are more versatile. And it would simplify plumbing a lot to put everything in the same place, vs pumping brine up many roofs, and water down again.
