Yes, but that's among the most expensive ways of approaching the problem. In regions where it's feasible, evaporation approaches are far cheaper, which is why they're still the most widely used approach. In humid regions with a lot of precipitation like the gulf coast, though, you have to take more expensive and energy-intensive approaches to concentrate things.
A serious issue with pond evaporation is that it wastes all the waster. The DLE approach evaporates 98% less water. It's increasingly being used even in places like Chile where evaporation can be used.
