The San Diego County Water Authority in June won substantial victories in a state Court of Appeals decision on rates set by the Metropolitan Water District of Southern California (MWD) that will affect how much everyone in this region pays for water. These victories are potentially worth more than $1 billion for San Diego ratepayers. While that seems like a lot of money — and no doubt it is — there are still billions more at stake, which is why the water authority must continue to pursue this litigation on behalf of San Diego County ratepayers.
