(1) What about evaporator of kind other than salt pond?

https://en.wikipedia.org/wiki/Evaporation_pond mentions

"Salt evaporation ponds produce salt from seawater. They are also used to 
dispose of brine from desalination plants. 

Mines use ponds to separate ore from water. Evaporation ponds at contaminated 
sites remove the water from hazardous waste, which greatly reduces its weight 
and volume and allows the waste to be more easily transported, treated and 
stored. (...)"

(2) not sure is landuse=basin is the best tag,
note https://wiki.openstreetmap.org/wiki/Tag:landuse%3Dbasin
"An area of land artificially graded to hold water."

I would consider a brand new tag for that, but have no good idea right now.
