How do I sell water to neighbors in SimCity 2013?

[Guest]

Like the title says, how do I do this? When I click on the water icon in region mode it states that there is no water to buy, but nothing about selling. I have a neighboring city that needs water so how do I sell it to them?

They buy it from you, you dont have to sell it to them.
When they go to region view from their city they should see available water for purchase.

(You can always use the sewage>water trick if you cant purchase the water)
