Twenty-five years ago, the San Diego County Water Authority, the organization that provides water to the region’s 24 water districts, decided its water supplies had become a bit too iffy during a severe drought and set about diversifying its sources of supply.

The Metropolitan Water District of Southern California, the county water authority’s main supplier, felt dissed when its largest customer publicly questioned the reliability of its services.

According to a San Diego Union-Tribune editorial, the water authority has been persona non grata with the MWD ever since.
