Having tried little else to save its water supply, Corpus Christi is considering an option that no other Texas city has embraced: seawater desalination. The strategy has long been considered a far-in-the-future option because of its cost, logistical challenges and environmental side effects.

Nonetheless, Corpus is plunging ahead in the hopes of diversifying its water supply, which consists entirely of three shallow surface water lakes that rapidly shrink during droughts.

City officials argue that desalination would provide an uninterruptible supply of water for the city’s growing port and industrial area.
