Can Wastewater Help Us Adapt to Climate Change?

KQED, 8/22/23: When recycled for drinking, the millions of gallons of water that Bay Area residents flush down toilets and showers every day could be cleaner than the pristine Hetch Hetchy
Cal Matters, 8/1/23: Waste would undergo extensive treatment and testing before it’s piped directly to taps, providing a new, costly but renewable water supply. The state’s new draft rules are more than a decade in the making.
Press Release, July 12, 2023: Since it got its start with the City of Santa Rosa’s Geysers Recharge Project in 1998, the Windsor-based firm has coordinated public outreach for more than $2 billion worth of recycled water projects, from purple pipe to potable reuse. During the past 25 years, the firm has worked on a variety of recycled water projects in California, Oregon, Washington, and Nevada, including purple pipe projects for agricultural and landscape irrigation, potable reuse and advanced purified recycled water.
KUNR Public Radio, July 5, 2023: The Reno area doesn’t have a history of threatened water supplies, and historic snowfall this past winter eased drought conditions in Nevada and across parts of the Mountain West. But that could shift quickly with climate change.
NASA, June 20, 2023: For space missions that venture beyond low Earth orbit, new challenges include how to provide basic needs for crew members without resupply missions from the ground. NASA is developing life support systems that can regenerate or recycle consumables such as food, air, and water and is testing them on the International Space Station.
The Associated Press, October 21, 2022: Colorado’s water quality agency gave unanimous preliminary approval to regulate direct potable reuse — the process of treating sewage and sending it directly to taps without first being dispersed in a larger water body.
Water Finance & Management, June 20, 2022: Water management strategies tend to evolve gradually with slowly changing community needs. That’s rare in California, where continued population growth and prolonged drought exacerbated by climate change have sparked dramatic change, through initiatives such as the Pure Water San Diego program and Orange County’s Groundwater Replenishment System, now undergoing final expansion. Further north along the Pacific Coast, Pure Water Soquel is another example of timely, transformative action for a more resilient and reliable water supply.
ENSIA, August 8, 2021: For decades, water officials in San Diego, realizing the city was facing an ever-drier future, have worked to make the idea of what’s known as “direct potable reuse,” or DPR, more palatable to residents. In the 1990s, that turned into an uphill battle. The technology delivers purified wastewater to customers’ faucets without an environmental buffer — such as a groundwater aquifer, river or other go-between — prior to distribution, so opponents labeled it “toilet-to-tap.” The epithet stuck and torpedoed the Southern California city’s water recycling plans.
Counter Punch, April 27, 2021: The Southwestern states, in particular, have faced frequent and ongoing droughts over the past two decades, and traditional water supplies are failing. As groundwater supplies in the region have depleted substantially, rainfall has decreased and the costs of importing water have risen substantially.
