The basics of the relationship between water and energy are
well known, but California’s recent drought revealed something
surprising about this connection. When the state mandated a 25
percent drop in water use, the resulting energy savings turned
out to be even higher than expected. This prompted the
Department of Energy to find ways of making water more energy
As of Friday, 10 workers are quarantined inside the Claude

Fresh water shortages have made desalination a possible
solution for supplementing the overall water supply. To address
this issue, a team of industry professionals and researchers
have formed National Alliance of Water and Innovation to
jointly examine the critical technical barriers and research
needed to lower the energy cost of desalination and other water
The contraption, reminiscent of Rube Goldberg, would produce
two of Southern California’s most precious and essential
resources: water and electricity. … The idea, developed by
Silicon Valley-based Neal Aronson and his Oceanus Power & Water
venture, caught the attention of the Santa Margarita Water
District. The agency quickly saw the project’s viability to
fill a void.
Extracting salt from water seems like an easy fix to a global
problem, but the process of desalination can be expensive, and
it can also have a huge impact on the environment. That’s why
some researchers are looking into how to lower the cost and
California American Water has received a 90-day extension of

Understanding why desalination is so critical to California’s
water future is a lot like building a personal budget. With a
changing climate, growing population and booming economy, we
need to include desalination in the water supply equation to
help make up an imported water deficit.
Eight years after the regional desalination project fell apart,
the legal battle over its unraveling appears to be nearing a
conclusion. A proposed settlement has been reached among the
parties involved… It was presented on Monday in the San
Francisco Superior Court overseeing the long-running lawsuit.
South Coast Water District will gear up to undertake its next
milestone for desalination: financing the project. On Thursday,
Jan. 9, after press time, General Manager Rick Shintaku
requested authorization from SCWD’s Board of Directors to enter
into an agreement with Clean Energy Capital to conduct a cost
analysis for the proposed desalination project.
Nobody likes to look out to the Pacific Ocean and see oil
derricks on the horizon. That’s why California wisely banned
new offshore oil drilling 50 years ago. But in Monterey County,
coastal views are limited by a relic of a bygone era: a giant,
industrial sand plant right on the dunes between Highway One
and the ocean.
A mechanical engineer at Carnegie Mellon University has
developed a new, micro-thin material to make membrane water
desalination even better. Amir Barati Farimani, with fellow
researchers Zhonglin Cao and Vincent Liu, has calculated how
much better his metal organic framework (MOF) works than the
traditional membrane method.
With Poseidon Water’s plans for a Huntington Beach desalination

West Basin Municipal Water District took the next steps Monday
toward building a desalination facility in El Segundo, a
project that has drawn fierce opposition from conservation
groups — including some who staged a rally before the meeting.
Seeking to fortify the city against future droughts, the Palo
Alto City Council endorsed on Monday a long-term agreement with
Santa Clara Valley Water District and Mountain View to build a
salt-removal plant in the Baylands and then transfer the
treated wastewater south.
A proposed desalination plant in El Segundo could soon be one
step closer to reality. The West Basin Municipal Water District
will hold a special meeting in Carson on Monday, Nov. 18, where
the board will weigh whether to certify an Environmental Impact
Report for the proposal. … The board has not yet selected a
company to build the proposed plant, which could cost more than
Cal Am Water’s experts may have seriously underestimated the
potential impact the company’s proposed desalination plant
would have on the existing water supply nearby, the staff of
the California Coastal Commission concluded in a report
released this week as a supplement to its exhaustive report on
the overall project.
If California goes into another drought and Kern County needs
an extra supply of water, Santa Barbara is open to partnering
with communities like Kern County. “We’re able to do exchanges
with people, so you could in theory have someone in the Central
Valley be a partner in desal,” said Joshua Haggmark, water
resource manager for Santa Barbara.
In places like San Diego and Dubai, where freshwater is scarce,
humans turn to machines that pull the salt out of seawater,
transforming it into clean drinking water. … Many researchers
are working to improve the technology so it can reach more
people — and address climate change without contributing to it.
Now is the time to focus on Pure Water Monterey and scrap the
desal plans. If 10 years from now the recycled water project
doesn’t do the trick, and there’s still a need for a desal
plant, we can be optimistic that future advances in technology
will make any desal option more environmentally-friendly and

While cities on the Monterey Peninsula have been working to
address housing needs and the business community is actively
looking to create more jobs, there is one component they all
need to complete their plans – reliable, drought-proof access
The project is the first of its kind to tap agricultural
run-off among a variety of wastewater sources for conversion
into potable, drinking water that would represent about a third
of the Monterey Peninsula’s new drinking water supply.
Over 30 years, Cal Am’s Desal would cost $1.2 billion while the
Pure Water Monterey expansion would be only $190 million. But
the cost in dollars is not the only comparison that should be
made. The environmental cost comparison is also dramatic.
In an effort to widen the use of a nearly limitless — but
expensive — source of water for California and other places
worldwide that are prone to shortages, Lawrence Berkeley
National Laboratory has been selected to lead a $100 million
project aimed at bringing down the cost of desalination.
The San Diego County Water Authority’s 2019 fiscal year report
on the Carlsbad ocean desalination plant shows poor performance
at the facility. According to the report, Poseidon paid a
penalty of almost $2 million for non-delivery of water,
reaffirming concerns around affordability and reliability
raised by community advocates …
The Monterey Peninsula has gotten so good at conserving water
that there is no need to build a costly desalination plant for
decades – even if the region experiences unprecedented growth –
according to a report from the top executive at the Monterey
Peninsula Water Management District.
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.
Reaction has been predictably mixed to a new report that
concludes the Monterey Peninsula may be able to get by with
recycled water instead of desalinated water for the next two
decades and perhaps beyond.
Completion and operation of the much-anticipated Pure Water
Monterey recycled water project have been delayed again and it
is now expected to miss another key water delivery deadline set
for the end of this year.
The groundbreaking ceremony was decades in the making for the

Fifth graders now have a space to learn everything about water,
from conservation to careers in the water industry. The Hydro

District (CVESD), the Otay Water District and Sweetwater
Authority. This facility consists of a classroom right next to
the Richard A. Reynolds desalination plant, which is estimated
to receive about 4,500 students every school year.
Arguing that Monterey County officials improperly ignored new
groundwater impact information and a viable, even preferable
recycled water alternative, Marina Coast Water District has
sued the county and California American Water over the county’s
narrow approval of Cal Am’s desalination plant permit.
Desalination began to lose its urgency among Californians and
their public officials two years ago, after the drought-busting
winter of 2016-17, when heavy rain and snow ended dry
conditions in most of the state. The idea of drawing potable
water from the sea became even less of a priority this year,
when an autumn of record-level fires gave way to one of the
state’s wettest winters on record.
Whenever the price of other water goes up, desalinating Pacific
waters becomes more enticing. It will become more so if the
price of filtering minerals out of salt water drops. But if the
price and availability of fresh water remains reasonable, as it
surely will be this year, desal stays in the back seat.
Jeff Urban, a staff scientist who specializes in new materials

Seven and a half years after it was formed, the Monterey
Peninsula Regional Water Authority is moving forward with a
smaller, less expensive version of itself. … The authority
has completed the vast majority of its mandate in backing a new
water supply for the Peninsula and can now be expected to shift
its focus toward dealing with the state water board’s Carmel

A long-awaited Montecito Water District rate study, planned for
release this May, will not be finished until later this year,
officials said this week. The study can’t proceed until the

Monterey County supervisors voted Monday to let California
American Water start construction on its desalination plant
even before the state Coastal Commission makes a decision on
the technology involved.
Only 15 out of the thousands of desalination plants operating
today worldwide are powered by nuclear. A small one is at the
Diablo Canyon Nuclear Plant in California, slated to be closed
soon. The plant could power several huge desalination plants
for decades that could desalinate its own cooling water,
removing the most commonly stated problem with the plant.
The Monterey County Board of Supervisors will decide July 15 if
California American Water will be permitted to build its $329
million desal plant. The supervisors will be hearing appeals

The desalination plant would have seven wells sloping into the
ground and sucking up water underneath the dunes, removing the
salt, and sending it to cities on the Monterey Peninsula …
but not Marina. They wouldn’t get any of the desalinated water
because they’re not served by CalAm. Biala and other Marina
residents oppose the plant because they think it will cause
irreversible damage to their town’s ecosystems.
The slower timeline for Huntington Beach resulted in it facing
new, stricter regulations and additional delays. The
controversial plant still needs two major permits, opponents
remain steadfast and a recent water-supply study raised
questions about the cost and need for the project.
The organization best known for backing a public takeover of
Cal Am’s local [Monterey Peninsula] water system filed an
appeal of the Planning Commission’s narrow approval of a permit

project proposal fails to properly address several key details,
including groundwater rights, and calls for the county to
require a supplemental environmental review before considering
The combination of droughts and floods has given rise to a
process known as saltwater intrusion — what San Jose Mayor Sam
Liccardo refers to as his city’s greatest climate threat. …
In coastal regions like San Jose, overpumping allows seawater
to seep into the city’s aquifers, exposing local residents to

Coastal Commission staff on Monday reiterated to The Herald
that Cal Am can appeal the city’s denial under the state’s
Coastal Act because the city charges an appeal fee. They called
the city’s own rules “internally inconsistent” and noted the
Coastal Act’s regulations supercede local ones.
We have learned over the last six years that the water need for
Santa Cruz to meet its own annual demand is 1.1 billion gallons
less than thought in 2014, when the two districts were pursuing

People are interested in California water problems, and they
ask reasonable questions. Here is a first installment of short
science-based answers to some reasonable questions often heard
at public and private discussions of water in California.
Even as stakeholders in the Colorado River Basin celebrate the recent completion of an unprecedented drought plan intended to stave off a crashing Lake Mead, there is little time to rest. An even larger hurdle lies ahead as they prepare to hammer out the next set of rules that could vastly reshape the river’s future.
Set to expire in 2026, the current guidelines for water deliveries and shortage sharing, launched in 2007 amid a multiyear drought, were designed to prevent disputes that could provoke conflict.
It was the best attended city council meeting that didn’t
happen. … But when everyone filed into City Hall, no
councilmembers were in sight. Only Assistant City Attorney
Deborah Mall appeared. She said Cal Am had withdrawn its appeal
at the last minute on April 29 and the council could not
proceed with a hearing.
Poseidon Water might be fighting for its desalination future in
Huntington Beach, but the corporation’s representatives will be
in front of the California Coastal Commission for an entirely
different matter on May 9: the restoration and conversion of a
90.9-acre salt pond to tidal wetlands and 34.6-acrer Otay River
floodplain site in San Diego.
In one key respect, California is lagging behind many other
parts of the world. Climate change is causing drought and water
shortages everywhere, but California has been slow to adopt a
solution that over 120 countries are using: desalination.
Cal Am announced it had been told by city officials its request
for the mayor and two council members to recuse themselves due
to alleged bias against the desal project would not be honored.
The company will now appeal the commission’s denial directly to
the Coastal Commission.
Citing long-running efforts to secure a new Monterey Peninsula
water supply and the state-imposed deadline for reducing
unauthorized water usage, the county Planning Commission
approved California American Water’s desalination plant north
of Marina on Wednesday.
Since Jim Madaffer became chairman of the board of the San
Diego County Water Authority, two long-time staffers have left

tunnel project to give San Diego a second connection to water
from the Colorado River. The tunnel plan would be the single
largest, most expensive and complex project the Water Authority
has ever attempted.
Considered by many the key to long-running efforts to cut
unauthorized pumping from the Carmel River, California American
Water’s proposed desalination plant project is headed to the
Monterey County Planning Commission next week. On Wednesday,
the commission is set to conduct a public hearing on a combined
development permit for the proposed 6.4-million-gallon-per-day
Cal Am is seeking California Public Utilities Commission
approval to start raising local customers’ rates by May 11 to

to local customers.
When you turn on a faucet on the Monterey Peninsula, you’re
consuming water that’s been illegally pumped from Carmel River.
Now, after more than two decades of this, scores of public
officials, utility executives and citizen advocates are working
– and sometimes fighting – to replace the region’s water supply
before state-mandated sanctions kick in. California American
Water is forging ahead with its plan: a desalination plant near
Construction starts this month on a $1.5 million test well to
show whether desalinated groundwater could supplement the
drinking water supply for 86,000 customers of the Olivenhain
Municipal Water District. The district serves parts of
Encinitas, Carlsbad, San Diego, San Marcos, Solana Beach and
neighboring communities, and relies almost entirely on water
imported from the Colorado River and Northern California.
As a result of California’s outdated water infrastructure and
persistent droughts, some elected leaders are shifting the
focus to investing in seawater desalination to help address the
state’s water crisis. While less than half a dozen desalination
plants currently exist in the state, the idea is gaining
momentum and greater support at the state level.
San Diego water customers will soon pay $6 to $13 more a month
to fund the first part of the city’s new recycled water
project, according to a newly released estimate. The city is
working on a multibillion-dollar plan to purify enough sewage
to provide a third of the city’s drinking water by 2035.
The city is suiting up for construction of a new facility later
this year that will purify recycled water to create a new,
local source of drinking water for residents by 2022. Pure
Water Oceanside is a water purification system that aims to
reduce the city’s reliance on imported water, improve
groundwater resources, increase local water supply and
strengthen the city’s resiliency to drought and climate change
in an environmentally sound process.
Antioch’s plan to build a long-awaited brackish desalination
plant got a major boost this week when the City Council

The only Monterey Peninsula city with its own desalination
plant is looking to install new intake wells to help balance
the salinity levels and increase output to the
300-acre-foot-per-year design capacity of the almost
10-year-old Sand City desalination facility. The plant, which
is owned by Sand City and is operated by California American
Water, is currently running at 200 acre-feet per year.
The city of Oceanside is receiving more than $2.6 million in
federal funding to increase its local water supply and to
reduce brine discharge into the ocean. The city will receive
$2.623 million in funding from the Bureau of Reclamation’s
WaterSMART’s Desalination Construction Projects under the Water
Infrastructure Improvements for the Nation Act (WIIN), subject
to federal appropriations.
A week after the Marina Planning Commission unanimously

arguing the planning commission erred in its denial of a
coastal development permit for parts of the proposed desal
A recently completed study on the cost effectiveness and
financial risk of proposals to meet water supply demands
through 2050 concludes that the controversial Poseidon
desalination project in Huntington Beach would produce more
water than the Orange County basin needs and cost ratepayers
far more than alternatives such as recycling and capturing
To make a real structural shift, utilities must engage a
broader group of actors in the process, and that is where cap
and trade comes into play, this time for water systems. … A
smattering of cap-and-trade schemes already aim to address
water pollution in various water bodies. Yet most such trading
programmes have focused on water quality. Now their frameworks
must be expanded to account for water quantity, encouraging
efficiency, reinvestment, and supply diversification.
Oceanside announced it will receive a $2.6 million federal
grant to build two more of the wells that the city has used for
more than 20 years to supply a portion of its drinking water.
The wells pump brackish water from what’s called the Mission
Basin, an area near the airport, the old swap meet property and
the San Luis Rey River. The city filters the water using the
same reverse osmosis process used on a much larger scale in
Carlsbad to desalinate seawater.
One tunnel or two, neither idea adds a drop of the water to
needs of the nearly 40 million people who call California home.
The tunnels simply divert existing water supplies while putting
in severe jeopardy the largest freshwater estuary west of the
Mississippi River, the Sacramento-San Joaquin River Delta that
juts into the western edge of Stockton. Clearly, there must be
better solutions. Three approaches leap to mind: storage,
conservation and desalination.
Although Santa Monica may be the most aggressive Southern California water provider to wean itself from imported supplies, it is hardly the only one looking to remake its water portfolio.
In Los Angeles, a city of about 4 million people, efforts are underway to dramatically slash purchases of imported water while boosting the amount from recycling, stormwater capture, groundwater cleanup and conservation. Mayor Eric Garcetti in 2014 announced a plan to reduce the city’s purchase of imported water from Metropolitan Water District by one-half by 2025 and to provide one-half of the city’s supply from local sources by 2035. (The city considers its Eastern Sierra supplies as imported water.)
The new administration has signaled a shift in water policy by
specifically talking about turning salty water potable after
Gov. Gavin Newsom (D) said he would support only a single
tunnel as part of the project known as WaterFix. … But
talking up desalination is much easier than making it a
reality. In the four years since California updated its
desalination regulations, none of the eight applications for
new or expanded facilities has been approved. Meanwhile, the
costs for the projects keep rising and the state has few
details about its plans.
As Californians, I believe we must look west to the Pacific
Ocean, where seawater desalination offers a proven, climate
change-resilient solution. No longer do we need verification
from Israel, the Middle East and Australia, where desalination
facilities have literally helped save lives and fend off
debilitating droughts due of climate change. Now, we can look
much closer to home — in San Diego.
In a recent paper, Stephanie Pincetl, director of the
California Center for Sustainable Communities at UCLA, and
co-authors argue that investments made over the years to
fortify the city’s supply with additional imported water have
not solved LA’s water shortages. … The paper asserts that LA
could become water self-reliant by strategically investing in
local supplies, and offers several concrete strategies for
improving LA’s water security.

San Diego is in the midst of spending roughly $3 billion on a
massive new water treatment system, but city officials can’t or
won’t tell customers how that will affect their water bills.
New water recycling plants will eventually purify enough sewage
to provide a third of the city’s drinking water. In
December, Voice of San Diego asked the city to estimate how
much customers’ bills will increase because of the Pure Water
project. The city, after weeks of delay, finally declined
last week to offer any estimate because “there is no simple
calculation” they could perform.
California American Water’s Monterey Peninsula desalination
project is in the midst of another critical phase even as
a Carmel River pumping cutback order milestone requiring the
start of construction looms later this year. … The city of

the most fiscal risk of key water projects being pursued in
Orange County, according to a newly released draft report.
The San Diego County Water Authority Friday announced it will
cease work on a seawater desalination plant at Camp Pendleton
because of excessive permitting and cost hurdles by the State
After six and a half years of review, the state Public
Utilities Commission on Thursday approved a permit for
California American Water’s Monterey Peninsula Water Supply
Project, including a North Marina desalination plant.
In a sign of how seriously the state Public Utilities
Commission is taking the debate over the future of water supply
on the Monterey Peninsula, all five commissioners attended a
CPUC oral argument hearing on California American Water’s
proposed desalination project in San Francisco on Wednesday.
Several of those who attended the hearing said three of the
five commissioners asked a number of questions of the parties
to the desal project proceeding, and all five appeared “engaged
and interested” in the issue.

water were overridden by the desire to fortify water supplies
when the Orange County Water District board voted 6-2 Wednesday
to approve non-binding contract terms with Poseidon, which has
spent 20 years on the desalination plant proposal for
The day of reckoning is drawing near for Huntington Beach’s
long-planned desalination plant, which would help quench Orange
County’s thirst with sea water and free up imported water for
the rest of the Southern California. Twenty years and $50
million into the process, officials with plant purveyor
Poseidon are optimistic they will get their final two permits —
possibly by year’s end.
Sin City has never been a place that thinks small. So it should
come as no surprise that Las Vegas – about 300 miles from the
Pacific Ocean – is pondering seawater desalination to meet its
long-term water demand. That doesn’t mean Vegas plans to build
a pipeline to the ocean. More likely, it would help pay for a
desalination facility in a place like Mexico, then trade that
investment for a piece of Mexico’s water rights in the Colorado
Not if, but when. That’s the future of water desalination
plants in Arizona, according to the head of the state’s water
department. They are controversial and expensive, but Arizona’s
current leadership views desalinated water – or “desal” – as
key to the state’s long-term water plans. Arizona sits atop an
estimated 600 million acre-feet of brackish water.
Several parties including the Monterey Peninsula mayors
regional water authority have called for delaying California
American Water’s proposed Marina desalination plant for a year
or more to allow pursuit of a proposed Pure Water Monterey
recycled water expansion and continued settlement talks in an
attempt to avoid litigation.
California water officials have approved $34.4 million in
grants to eight desalination projects across the state,
including one in the East Bay city of Antioch, as part of an
effort to boost the water supply in the wake of the state’s
historic, five-year drought.
With Tijuana and other rapidly growing coastal cities heavily
dependent on the Colorado River, Baja California urgently needs
to find new water sources. Baja California Gov. Francisco Vega
de Lamadrid’s administration has offered a solution: Build the
largest desalination plant in the Western Hemisphere, enough to
ensure a supply for decades to come.
A coalition of non-profits is asking a superior court to
reverse a state agency’s decision to greenlight a
long-proposed, controversial desalination plant in Huntington
Beach. … The Poseidon desalination plant has been proposed
for the site of the AES power plant on Pacific Coast Highway in
Huntington Beach for nearly 20 years, and has been continually
challenged and fought by environmental groups.
The small Stinson Beach County Water District is looking at
desalination as a way to guard water supplies as hoards descend
on the beach community in summer, and as drought and climate
change loom. The district serves about 730 residences and 2,000
people in and around Stinson Beach, drawing water from four
creeks as well as groundwater supplies.
The final round of battles between the people who want to build
the Poseidon desalination water plant, and the grass roots
environmental groups who oppose it, began Thursday in a crowded
city hall chamber in Huntington Beach. … The
three-member [State Lands] commission voted late Thursday to
approve the project as long as the operators agree to eliminate

didn’t halt criticism of the controversial facility.
A desalination plant planned for Huntington Beach and more than
a decade in the making got a small step closer toward opening,
this week, after its application with the regional water
district was determined to be ready for consideration. The
agency also has enough information to make a decision about
whether the project complies with the state’s ocean plan.
With Baja California pushing forward on its plan for a massive
desalination plant in Rosarito Beach, a ground-breaking
proposal to pipe some of that water to the United States has
overcome a key hurdle. The U.S. State Department’s approval of
a presidential permit marks a step forward for the Otay Water
District and its vision for a cross-border pipeline to import
the desalinated water from Mexico.
State Public Utilities Commission officials are seeking input
on whether to conduct new hearings on California American
Water’s proposed Monterey Peninsula desalination project to
address a number of issues, potentially including an updated
project demand forecast and desal plant sizing evaluation that
could lead to a smaller initial plant that could be more easily
expanded as demand grows in the future.
As California officials struggle to decide on long-term fixes
for the receding lake, there’s new momentum around an old idea:
importing seawater from Mexico’s Sea of Cortez, and using the
area’s plentiful geothermal power to desalinate that water. A
subsidiary of Warren Buffett’s Berkshire Hathaway Energy, which
already operates 10 geothermal plants in the area, is
developing a seawater desalination proposal and has pitched it
to lawmakers in Sacramento.
The long debate over Poseidon Water’s proposed ocean
desalination plant in Huntington Beach continued this week as

— or slightly salty — groundwater is more than 35 times the
amount of fresh groundwater used in the United States each
A California American Water official argued the company’s
desalination project can secure key permits and approvals
within six months of certification of the final project
environmental review document and start construction shortly
afterward, despite a series of delays involving the draft
report and the prospect of seeking a critical permit from the
city of Marina.
A Monterey Bay National Marine Sanctuary representative said
the latest delay involving California American Water’s proposed
Monterey Peninsula desalination project — a 30-day extension of
the public comment period on the project’s draft combined state
and federal environmental review document — could push back
finalization of the report by a month.
California’s historic drought may be winding down. But water
officials across the Golden State are increasingly exploring a
hidden but promising way to add to the state’s water supply:
removing salt from the billions of gallons of brackish — or
distastefully salty — water that lies deep below the Earth’s
A document purportedly leaked from the Trump administration
indicates that the proposed desalination plant in Huntington
Beach is among 50 infrastructure projects nationwide that the
president has designated as a priority.
The U.S. imports vehicles, equipment, fresh produce and other
goods from Mexico. That list may soon include water too, now

of California coastline. … A few hours later,
environmental advocates held a town hall two miles away in
Poseidon Water hopes to help quench Orange County’s thirst, but
first the company’s proposed desalination
project must slake a thirst of its own. That’s why
Poseidon has long eyed a coastal power plant that has, for more
than a half-century, sucked up seawater to cool its massive
A protracted conflict over whether and how to protect fish from
dying at desalination plants is clouding prospects for what
would be California’s second large plant of this type – and for
the future of desalination along the entire
California coastline. For years, a proposed Poseidon
Resources desalination plant in Huntington Beach in Orange
County has been kept in limbo.
A new ruling issued by a state Public Utilities Commission
member has indicated the full commission likely wouldn’t
consider approval of California American Water’s Monterey
Peninsula desalination project until March 2018, four months
after company officials had hoped, and suggested that
consideration could be delayed even further.
Backers of a new Monterey Bay desalination project think they
have found a fix for the environmental problems posed by most
seawater intakes: Instead of drawing seawater from the beach,
they plan to draw from the one of the world’s deepest marine
In what local water activist Ron Weitzman promises is a
precursor to further litigation, the Water Ratepayers
Association of the Monterey Peninsula has filed suit against
the state Coastal Commission and Monterey County seeking to
halt California American Water’s slant test well program for
the proposed desalination plant project.
Carlsbad’s new desalination plant went through years of
regulatory review and faced 14 legal challenges from
environmental groups before it opened last year. Six months
after opening, it’s still facing regulatory hurdles, including
one that’ll make the water it produces more expensive.
A desalination plant proposed near San Juan Creek could produce
as much as 15 million gallons of drinking water daily and
create a reliable source for South County-area reserves in the
wake of an earthquake or drought, officials said. … On
Thursday, district officials will hold a community meeting to
discuss the project and its environmental report.

supplier’s plan to buy desalinated water from a proposed $1
billion Huntington Beach plant.
In response to the recently launched Poseidon desalination
plant in Carlsbad, state officials have agreed to dramatically
ease water conservation goals in San Diego for almost all
residential water users. The adjustments will nearly cut in
half required water savings throughout the region, the San
Diego County Water Authority announced Thursday.
California American Water’s latest Monterey Peninsula water
supply project cost estimates show a larger desalination plant
would cost the same as previous estimates, but a smaller desal
plant would be more expensive. That would potentially squeeze
the cost of a supplemental recycled water project unless it
qualifies for grants and low-cost financing.
Poseidon Water’s desalination plant in Carlsbad is poised to
begin regular operations within days — decades after water
officials first considered harvesting drinking water from the
sea and 14 years after they formally took the first steps
toward its construction. The opening, to be celebrated with an
anticipatory ceremony Monday, will be a milestone for the
company, for arid San Diego County and for all of California.
The $1-billion desalination plant coming online next month in
Carlsbad will fit right in with years of careful planning and
investment in water supply in San Diego County. It will also
worsen a peculiar San Diego problem amid a multiyear drought:
an oversupply of water.
This 2-day, 1-night tour in the San Diego County included a
private tour of the new Carlsbad ocean desalination plant,
the largest such facility in the Western hemisphere and designed
to increase the San Diego area’s water supply reliability.

Monterey Peninsula desalination project by the Monterey Bay
National Marine Sanctuary and the state Public Utilities
Commission will likely take about a year to draft and finalize,
according to representatives of both agencies.
The fate of a proposed water desalination plant in Huntington
Beach remains uncertain after a panel of experts has concluded
that it would be too expensive to build it using intake pipes
under the sea floor. That was the approach favored by the
California Coastal Commission, whose approval is needed to
Facing another delay on California American Water’s
desalination project, the Monterey Peninsula regional water
authority weighed in this week on the major reasons for the
delay — the apparent Geoscience conflicts of interest and the
stalled test well operation.
California American Water officials have acknowledged using
patented slant well technology by Geoscience president Dennis
Williams in the Monterey Peninsula desalination project after
previously denying it.
