Is anyone drinking recycled wastewater already?

Yes! Reuse occurs when wastewater has been discharged to rivers or lakes, then withdrawn, treated and distributed downstream. For instance, there are more than 300 wastewater outfalls on the Colorado River, a major source of drinking water for Southern California. In this situation, public health is protected through treatment required by the Clean Water Act and Safe Drinking Water Act.

Planned potable reuse started in California in 1962 through groundwater recharge in Los Angeles County. The largest planned potable reuse project is in Orange County, where the water agency has been injecting purified wastewater into an aquifer for decades, then reusing it to serve millions of people each year. Anyone who’s visited Disneyland has drunk potable reuse water.
