People Need to Drink More Recycled Wastewater


But if you can recycle water to a large extent, you have a strong fence against thirst. “That’s a more reliable supply, which can reach that wastewater flow, clean it up, and then use it to fill the demand for other supplies,” said Michael Kiparsky, director of the Wheeler Water Institute at UC Berkeley.

And really, recycling water is an investment. As water grows scarcer in the West, it is also becoming more expensive. The cost of imported water in San Diego has dropped over the past 15 years. That could be a strong reason for voters about supporting water recycling projects as well. “People’s bills are also inspiring, aren’t they?” Gloria asked. “If you explain to them that if we can control this resource ourselves – that we don’t have to rely on water managers north of us, or a lot of agreements, water transfer agreements in other counties – if we can control it ourselves, there is more capacity to control costs. ”

The WIRED Guide to Climate Change

The world is warming, the weather is getting worse. Here’s everything you need to know about what humans can do to stop the destruction of the planet.

Historically, however, policymakers have had to combat the “ick factor” of recycled water. People may not trust it, even if it is surprisingly pure. (I already tried it before—It’s comforting and I’m not killed.) But Gloria points out that if your municipality draws water from Colorado or another stream, and you’re from other towns that do the same, you that drinking recycled water. “Everybody’s getting the water, using it, getting it, and it’s going to be here,” Gloria said. “So if you think you haven’t participated in some kind of water reuse, you’re probably wrong.”

But just like choosing stocks, it’s much safer to buy your stakes using a different portfolio of resources than having one asset. Any town that banks on a river or lake that has only one source of water is demanding hardship, as the more frequent and severe droughts that come with climate change will bring damage to the market. to a large extent. “Water today, I think, is our most natural challenge,” said Adrian Borsa, a geophysicist at the Scripps Institution of Oceanography in San Diego, who studies how aquifers store water. Drought is more certain to be almost a catastrophic danger in the West than other hazards that city planners must account for, such as earthquakes. “No more, ‘Oh, we’ll get this size 7½ at the San Andreas Fault.’ That happens sometimes, though sure We will face the challenges of water scarcity. “

That’s why Southern California cities are creating diversification in their portfolios. the Carlsbad Desalination Plant seawater is processed in the same way as that done by a recycling plant-by passing through membranes. It provides San Diego County with 50 million gallons of fresh water a day. In Los Angeles, 150 acres Destination Spreading Grounds acts like a giant sponge, soaking up storm water that then grows into an aquifer below. Elsewhere around LA, specially designed roadside greenspaces do the same, collecting water in underground tanks.
