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.”

Two Agencies Want to Secede From the San Diego County Water Authority

Water rates in San Diego are some of the highest in the country. So, two rural San Diego water agencies just came up with a novel way to save money: Buy water from Riverside County instead.

Leaders of two water agencies that serve about 50,000 people in and around Fallbrook are fed up with rising costs at the San Diego County Water Authority.

Local water agencies from across the region formed the Water Authority in 1944 to import water into the county from rivers hundreds of miles away. But, just in time for the Water Authority’s 75th anniversary, its future as the region’s main water supplier is in question.

Study of Brine Discharge from Desalination Plant Finds Good News and Bad News –

Before the Carlsbad Desalination Plant in Southern California began operations in 2015, scientists at UC Santa Cruz recognized an important opportunity to study the effects of the high-salinity brine that would be discharged from the plant into coastal waters.

Starting in 2014, they collected measurements of water chemistry and biological indicators in the area so they could compare conditions before and after the plant began discharging brine into the ocean.

County Water Authority Refinances Bonds for Savings of $18 Million – San Diego

The San Diego County Water Authority announced Wednesday that it has saved nearly $18 million in debt payments by refinancing the bonds used to construct part of the Claude “Bud” Lewis Carlsbad Desalination Plant.

The savings topped prior projections of $13.6 million through June 2046, according to the Water Authority. A total of 45 investors, including J.P. Morgan Securities LLC and Goldman Sachs, made nearly $2 billion in orders for the bonds.

Investors were attracted to the water authority’s strong credit and history of providing a reliable water supply, according to the agency.

County desalination plant celebrates 40 billion gallons of drinking water – San Diego

Representatives from San Diego County and Poseidon Water held a celebration Thursday for the Claude “Bud” Lewis Carlsbad Desalination Plant producing its 40 billionth gallon of drinking water.

The celebration also correlated with the third anniversary of the plant opening. The Carlsbad plant produces more than 50 million gallons of desalinated water each day and is the largest and most technologically advanced desalination plant in the U.S., according to the county.
