Can you share desalinization experiences for drought prone dispersed populations?

In the Guajira region of Colombia 4 years of extreme drought have rendered traditional runoff catchment reservoirs irrelevant while increasing salinity in the shallow aquifers have led to the implementation of extremely expensive options of deep wells (150 meters and more), shallower wells with desalinization and tanker distribution of desalinated sea water to extensive yet highly disperse settlements of indigenous Wayuu people. Is there anything that could be learned from other regions of the world facing similar challenges, low cost effective desalinization options or longer term approaches to replenishing the aquifers?
