Colorado River Shortages Drive Major Advances in Recycled Sewage Water Use

After more than two decades of drought, water utilities serving the largest urban regions in the arid Southwest are embracing a drought-proof source of drinking water long considered a supply of last resort: purified sewage.

Water supplies have tightened to the point that Phoenix and the water supplier for 19 million Southern California residents are racing to adopt an expensive technology called “direct potable reuse” or “advanced purification” to reduce their reliance on imported water from the dwindling Colorado River.

“[Utilities] see that the river is overallocated, and they see that the climate is changing,” said Kathryn Sorensen, former director of Phoenix Water Services Department. “They’re looking at this and understanding that the river supply is highly variable and extremely uncertain in the future.”

The Colorado River that sustains nearly 40 million people and more than 4 million acres of cropland across seven states is shrinking because of climate change and overuse. The river’s flows have declined approximately 20 percent over the past century, and a more than two-decade drought that began at the turn of this century has pushed the system to its limits.

With so much at stake, cities dependent on the river are strengthening water conservation measures and pursuing new sources of water with urgency.

Conference Highlights Deficiency of Models for Drought Situations

As the drought in California and across much of the western United States enters another summer season, several experts participated in a conference hosted by the California Department of Water Resources and the Water Education Foundation on Thursday to discuss issues of how modeling precipitation can impact decisions made by policymakers.

One of the main takeaways of the conference was that the current modeling programs are not effective as they should be in helping water districts, state water agencies and federal departments in planning water distributions.

Drought, Climate Change and Groundwater Sustainability — Western Water Year in Review

The ability of science to improve water management decisions and keep up with the accelerating pace of climate change. The impact to precious water resources from persistent drought in the Colorado River Basin. Building resilience and sustainability across California. And finding hope at the Salton Sea.

These were among the issues Western Water explored in 2020. In case you missed them, they are still worth taking a look at.

Framework for Agreements to Aid Health of Sacramento-San Joaquin Delta is a Starting Point With An Uncertain End

Voluntary agreements in California have been touted as an innovative and flexible way to improve environmental conditions in the Sacramento-San Joaquin Delta and the rivers that feed it. The goal is to provide river flows and habitat for fish while still allowing enough water to be diverted for farms and cities in a way that satisfies state regulators. But no one said this would be easy.

In Memoriam: William R. Gianelli, former director of California Department of Water Resources

William R. Gianelli, the Water Education Foundation’s second president and a leading figure in California water during construction of the State Water Project, died March 30, 2020, in Monterey County. He was 101.

Mr. Gianelli was president of the Foundation from 1985-1989 and made a major financial donation that helped the Foundation create an educational program for young professionals from diverse backgrounds, which was named the William R. “Bill” Gianelli Water Leaders Class in his honor. The year-long program began in 1997 and now includes more than 400 graduates.

Meet the Veteran Insider Who’s Shepherding Gov. Newsom’s Plan to Bring Climate Resilience to California Water

Shortly after Gov. Gavin Newsom called on state agencies to deliver a Water Resilience Portfolio to meet California’s urgent challenges — from unsafe drinking water, flood and drought risks from a changing climate to severely depleted groundwater aquifers and declining native fish populations — he appointed Nancy Vogel, a former journalist and veteran water communicator, to get it done. In an interview with Western Water, Vogel explains how the draft portfolio released Jan. 3 came together and why it should matter to average Californians.

Water Resource Innovation, Hard-Earned Lessons and Colorado River Challenges — Western Water Year in Review

Innovative efforts to accelerate restoration of headwater forests and to improve a river for the benefit of both farmers and fish. Hard-earned lessons for water agencies from a string of devastating California wildfires. Efforts to drought-proof a chronically water-short region of California. And a broad debate surrounding how best to address persistent challenges facing the Colorado River.

 

Can a New Approach to Managing California Reservoirs Save Water and Still Protect Against Floods?

Many of California’s watersheds are notoriously flashy – swerving from below-average flows to jarring flood conditions in quick order. The state needs all the water it can get from storms, but current flood management guidelines require reservoirs to dump water each winter to make space for flood flows that may not come. However, new tools and operating methods could lead the way to a redefined system that improves both water supply and flood protection capabilities.

As Wildfires Grow More Intense, California Water Managers Are Rewriting Emergency Playbooks

It’s been a year since two devastating wildfires on opposite ends of California underscored the harsh new realities facing water districts and cities serving communities in or adjacent to the state’s fire-prone wildlands. Fire doesn’t just level homes, it can contaminate water, scorch watersheds, damage delivery systems and upend an agency’s finances.

Often Short of Water, California’s Southern Central Coast Builds Toward a Drought-Proof Supply

The southern part of California’s Central Coast from San Luis Obispo County to Ventura County, home to about 1.5 million people, is blessed with a pleasing Mediterranean climate and a picturesque terrain. Yet while its unique geography abounds in beauty, the area perpetually struggles with drought.

Indeed, while the rest of California breathed a sigh of relief with the return of wet weather after the severe drought of 2012–2016, places such as Santa Barbara still grappled with dry conditions.
