Environment Report: Tijuana and San Diego Share a Sewage Problem But Not a Solution – California

Vicente Calderon from Tijuana Press and I spend a lot of time picking our way around the sewage-laden Tijuana River, asking ourselves: How is it still this bad?

Our latest story from the cross-border sewage crisis plaguing Tijuana and San Diego illuminated that the current approach to solving the problem is a lot like putting a Band-Aid on the stomach flu.

The Band-Aid in this case is $300 million that Congress has charged the Environmental Protection Agency with deciding how to spend. But really, and here’s the flu part of the allegory, a lot of Tijuana’s infrastructure is just old and broken, or was never even built to support the neighborhoods that popped up on its hillsides.

San Diego’s Successful Desal Plant Should Be a Model for California Water Policy – California

Often the value of a plan or project can best be judged by its opposition. In the case of the proposed Poseidon desalination plant in Huntington Beach, the forces lined up against it are clear indicators that it’s a worthwhile enterprise.

The Sierra Club calls the plant “rather pathetic,” “the most expensive and environmentally damaging way to secure Orange County’s future water supply.”

A research paper co-authored by the Natural Resources Defense Council, the California Coastkeeper Alliance, the California Coast Protection Network, and several other groups says that “given the significant energy, climate, and financial costs of desalination, California should prioritize water conservation, water use efficiency, stormwater capture, wastewater recycling, and renewably powered groundwater desalination.”

An Independent Colorado River Aqueduct Could Be a Money Saver for San Diego – California

There’s an old saying that those who don’t remember history are destined to repeat it.

And that certainly holds true when it comes to securing water for this semi-arid place we call home.

Those who have been around here since the early 1990s remember when we relied on a single Los Angeles-based water agency to meet almost all of our water needs — and we paid for it with traumatic supply cuts that crippled our economy.

A $5-billion water project could drill through Anza-Borrego park. Is it a pipe dream? – California

It would be arguably the most ambitious public works project in San Diego history.

The envisioned pipeline would carry Colorado River water more than 130 miles from the Imperial Valley — through the Anza-Borrego Desert State Park, tunneling under the Cuyamaca Mountains, and passing through the Cleveland National Forest — to eventually connect with a water-treatment plant in San Marcos.

An alternative route would run through the desert to the south, boring under Mt. Laguna before emptying into the San Vicente Reservoir in Lakeside.

Unsung Heroes: Carlsbad’s desalination plant workers – California

The Carlsbad Desalination Plant turns seawater into clean safe drinking water.

In an effort to keep delivering 50 million gallons of fresh water to the county daily the plant has gone on complete lockdown.As of March 19, 10 workers volunteered to quarantine themselves inside the Carlsbad plant for the next three weeks.

The company said workers will continue to monitor and adjust gauges and switches, watching for leaks – doing whatever is needed to safeguard San Diego County’s only significant local source of drinking water.

Water Authority Offers to Settle Long-Running Rate Dispute with MWD – California

The San Diego County Water Authority’s board offered Thursday to settle a long-running dispute over rates with the giant Metropolitan Water District of Southern California.

The offer, made following a special board meeting, asks MWD to make $140 million in payments to San Diego County water customers to cover claims from 2011 through 2020 and, in the future, follow new, transparent procedures in setting water rates.

“The Water Authority’s proposal would benefit residents across San Diego County, enhance understanding of how MWD’s rates are set, and provide more opportunities for our agencies to collaborate in ways that would benefit water management across the Southwest,” said Water Authority Board Chair Jim Madaffer.

Gage: Setting the Record Straight on Seawater Desalination – California

A recent news release posted on the Voice of OC website was clouded by mischaracterizations of the Claude “Bud” Lewis Carlsbad Desalination Plant, which provides an important source of drinking water for San Diego County and reduces our region’s reliance on the Sacramento-San Joaquin Bay-Delta.

The plant is the result of a historic public-private partnership between the San Diego County Water Authority and Poseidon Water to ensure supply reliability for more than 3 million residents across the region.

It helped to ensure that the Water Authority had sufficient water to meet demand during the last drought, and we are confident it will help us weather the next drought … and the one after that.

Poseidon Water Congratulates the National Alliance for Water Innovation (NAWI) Team on $100M DOE Desalination Hub – California

Poseidon Water is proud to be part of the National Alliance for Water Innovation (NAWI) Team that was selected to receive $100 million in funding from the U.S. Department of Energy (DOE) to establish a new Energy-Water Desalination Hub. The Hub’s purpose is to advance state-of-the-art technology and research in desalination.

Poseidon is a national leader in the development of water supply and treatment projects using a public-private partnership approach and manages the award-winning Claude “Bud” Lewis Carlsbad Desalination Plant.

Headquartered at Lawrence Berkeley National Laboratory (LBNL) in Berkeley, California, NAWI was created in 2017 to support the U.S. Department of Energy’s Energy-Water Desalination Hub.

Expert cautions developing countries over water desalination plants – San Diego

A water expert is cautioning developing countries over the establishment of water desalination plants as a means of providing potable water to the populace.

Jeremy Crutchfield of the San Diego County Water Authority in the USA says desalination (the treatment of seawater through the removal of salt) is a very expensive process because of the high cost of operation including the vast amount of electricity needed to operate such plants.

Water companies would usually establish treatment plants along rivers and streams which are not salty so the processing requires fewer inputs.

As Water Scarcity Increases, Desalination Plants Are on the Rise – California

Some 30 miles north of San Diego, along the Pacific Coast, sits the Claude “Bud” Lewis Carlsbad Desalination Plant, the largest effort to turn salt water into fresh water in North America.

Each day 100 million gallons of seawater are pushed through semi-permeable membranes to create 50 million gallons of water that is piped to municipal users. Carlsbad, which became fully operational in 2015, creates about 10 percent of the fresh water the 3.1 million people in the region use, at about twice the cost of the other main source of water.

Expensive, yes, but vital for the fact that it is local and reliable. “Drought is a recurring condition here in California,” said Jeremy Crutchfield, water resources manager at the San Diego County Water Authority. “We just came out of a five-year drought in 2017. The plant has reduced our reliance on imported supplies, which is challenging at times here in California. So it’s a component for reliability.”
