A state-court lawsuit challenges the amount charged to San Diego water users by the Metropolitan Water District in Los Angeles.
The San Diego Water Authority claims that it's been overcharged for water it buys from Metropolitan. Rates have climbed 75 percent in recent years while water usage has gone down.
Denise Vedder, Senior Public Affairs Manager at the SD County Water Authority, says the lawsuit is complex but the biggest problem is over-charging for transferring water.
San Diego is Metropolitan's largest client. Fifty percent of San Diego's water is provided by the Metropolitan Water District.
Vedder says it could be two to three years before the lawsuit is resolved. In the mean time, she expects water rates to continue to rise.
