At the San Diego County Water Authority, we scrutinize every dollar to make sure ratepayers get a good return on their investments in safe and reliable water supplies. But that isn’t the case everywhere – and it’s certainly not the case at the Los Angeles-based Metropolitan Water District of Southern California. Several steps removed form nearly 20 million residents it serves, MWD overcharged ratepayers $847 million more than the agency’s budgets said was needed from 2012-2015.
