Water may be life, but most residents of Southern California do not often reflect on the complex series of canals, pumps, and pipelines that connect where they live to water sources like the Colorado River, the Sierras, or the numerous water basins under LA County. Even less appreciated is the role water districts play in combining water sources, treating our water, and distributing it. Major water districts influence water quality and rates. They decide how to meet future water needs in an era of drought and climate change. These agencies determine if your water comes from sustainable local sources like conservation and recycling or from desert-damaging water mining projects like Cadiz.
