LKE has been discussed in a lengthy article on TIME.com:

I would cite a few sentences that discuss the water usage of evaporation ponds, Livent's hybrid DLE and the DLE solution to be used at LKE's Kachi project:

"Evaporation ponds: gigantic, lurid blue-green pools of brine. Such rectangular pools cover dozens of square miles in Chile’s Atacama desert, releasing tens of millions of metric tons of water into the air each year—at least 383.5 metric tons per metric ton of lithium carbonate produced, according to estimates by Argentine researchers.

"Livent’s global fresh water use for 2020—based mainly off of the Hombre Muerto project, its only active lithium carbonate mine—was 72.9 metric tons per metric ton of lithium carbonate equivalent (LCE) produced. In the lab, Lilac says it used 18 metric tons of water per metric ton of LCE. Lake says the rate at Kachi will be significantly below that, and that further water savings will come from plans to use brackish and recycled water."
