Toilet-to-Tap or the Future of California Water?

If there is one truism in California water, it is that there is not enough of it. In part to try to help address that issue, on December 19, 2023, the California State Water Resources Control Board (State Water Board) adopted the state’s first direct potable reuse (DPR) regulations. As detailed in the State Water Board’s press release, the new regulations represent the “most advanced standards in the nation,” provide a “climate-resilient water source,” and “add millions of gallons of additional drinking water.” However, is the picture quite that rosy?

Colorado OKs Drinking Treated Wastewater: Getting Over the ‘Ick Factor’

That water is then sent out through the city’s drinking water system.
