Opinion: Can We Save the Diminishing Colorado River?

/in , /by /The Hillby Bruce Yandle

Years of hot, dry conditions and population growth across the Southwest have brought painful reductions in Colorado River water flow allocations to Arizona, California, Nevada and Mexico. Based on a 1920s multi-state pact, the Department of the Interior sounds an alarm when the river’s reservoirs fall to extremely low levels, leaving states with no choice but to severely cut their water use, limiting consumption by agriculture, industry and citizens.

Helix Water District Gets $18 Million Loan for Water Reuse Projects

/in , /by

The Helix Water District has received an $18 million loan from the U.S. Environmental Protection Agency to support the Drinking Water Reliability Project. Helix will use the Water Infrastructure Finance and Innovation Act, or WIFIA loan, to increase the region’s drinking water resiliency by expanding water reuse opportunities and reducing the reliance on imported water.

The WIFIA loan will help fund infrastructure improvements for the East County Advanced Water Purification Program, pump station upgrades and cast-iron pipeline replacement throughout the district.

Developing new drought-proof water supply

“In California, we are purifying recycled water and ocean water to replace the water that nature used to provide,” said Helix Water District Board President Kathleen Coates Hedberg. “The only way we can afford to keep rates as low as we can and develop these new projects is through collaboration – multiple agencies working together and securing capital from multiple funding sources. We are partnering with neighboring agencies to develop a new, drought-proof water supply and we are so pleased that the EPA selected our project for funding.”

$18 million loan helps recycled water efforts

Specifically, Helix Water District will modernize existing pump stations, conveyance infrastructure, and distribution pipelines as well as install an aeration system in Lake Jennings to meet state surface water requirements.

By completing the project, Helix Water District will replace 30% of its water needs that are currently met by regional sources with an alternative source of purified water conveyed from the East County AWP, which received a separate WIFIA loan. This project also supports California’s Title 22 “Pure Water” objective to increase use of recycled water by at least 2 million-acre-feet per year by 2030.

Scheduled to be complete in 2026, the East County AWP will generate up to 11.5 million gallons per day of purified water— meeting approximately 30% of current drinking water demands for East San Diego County residents and businesses.

As a result of the WIFIA program’s flexibility and competitive rates, Helix Water District will save approximately $3.2 million by financing with a WIFIA loan. Construction and operation are estimated to create nearly 400 jobs.

“Future of water in the West”

“Helix Water District’s project represents the future of water in the West,” said EPA Deputy Assistant Administrator for Water Bruno Pigott. “EPA is proud to help finance these infrastructure upgrades that will increase water reuse and help secure reliable safe drinking water for generations to come.”

Established by the Water Infrastructure Finance and Innovation Act of 2014, the WIFIA program is a federal loan and guarantee program administered by EPA. The WIFIA program’s aim is to accelerate investment in the nation’s water infrastructure by providing long-term, low-cost supplemental credit assistance for regionally and nationally significant projects.

(Editor’s note: The Helix Water District and the Padre Dam Municipal Water District are two of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region. Water agencies in north San Diego County also received federal funds recently to support water recycling projects.)

A Rare Third Year of La Niña is on Deck for California, Forecasters Say

/in , , /by /Los Angeles Timesby Hayley Smith

Californians should brace for another year of La Niña as the stubborn climate pattern in the tropical Pacific is expected to persist for a third consecutive year, forecasters say.

The latest outlook, published Thursday by the National Weather Service’s Climate Prediction Center, has increased the chances of La Niña sticking around through November to 91%, a near certainty. The pattern may also linger into winter, with an 80% chance of La Niña from November to January and a 54% chance from January to March.

A Warmer, Drier West: A Detailed History and Possible Future of Water Use in the West

On October 13, 1893, Major John Wesley Powell, celebrated explorer, geologist and Civil War veteran, addressed delegates of the Second Irrigation Congress in Los Angeles, declaring to the capitalists, politicians and boosters attending (and whose main agenda was to develop the arid West), “What matters it whether I am popular or unpopular? I tell you, gentlemen, you are piling up a heritage of conflict and litigation over water rights, for there is not sufficient water to supply these lands.” Powell’s blunt prophetic statement did not win support. The delegates booed him off the stage.

A Drought Conversation with California’s Natural Resources Secretary

/in , , /by /Voice of San Diegoby MacKenzie Elmer

Days before the federal government shied-away from telling Western states how to curtail consumption of the drought-stressed Colorado River, Gov. Gavin Newsom unveiled a plan to speed-up projects that would help California use less of it.

To be clear: California hasn’t yet taken any big cuts from its Colorado River allocation, despite being its largest user. But, as pressure mounts, it might, writes Ian James of the Los Angeles Times. Newsom’s plan doesn’t mention the Colorado River directly, but it’s conceivable this is an effort to prepare California for that reality – or at least prove the state is doing something.

Opinion: Broad-Based Buy-In is Key to Bay-Delta Water Plan

/in , /by /CalMattersby Jennifer Pierre and David Guy

California is at a transformational moment when it comes to managing water. As aridification of the western United States intensifies, we have an opportunity to advance a better approach to flow management in the Sacramento-San Joaquin River Delta and our rivers through a process of voluntary agreements to update the Bay-Delta Water Quality Control Plan.

The agreements, signed by parties from Red Bluff to San Diego, propose a new structure for managing water resources in the Delta and beyond in a way that is collaborative, innovative and foundational for adapting to climate realities while benefiting communities, farms, fish and wildlife.

Carlsbad Desalination Plant Cuts Energy Demand to Help Avoid Blackouts

/in , /by

Poseidon Resources (Channelside) LP and the San Diego County Water Authority are temporarily reducing water production at the Claude “Bud” Lewis Carlsbad Desalination Plant to support statewide emergency energy conservation efforts during the extreme heat wave.

While the plant accounts for less than 1% of peak energy demand in San Diego Gas & Electric’s service territory, Channelside and the Water Authority are committed to supporting electrical reliability while ensuring continued delivery of safe and reliable water supplies. The partners reduced water production at the plant by about 20% for three days over the Labor day holiday weekend. Regular water deliveries were made from other sources. The reduced production helps decrease energy demand during the statewide emergency.

“The partnership by the Water Authority and Channelside is another reminder of the value our investments in cutting-edge technology and water supply reliability,” said Sandra L. Kerl, general manager of the Water Authority.  “Desal plant operations are nimble, so production can be ramped up and down in response to local needs. This flexibility underscores the value of regional water supply planning, which allows us to activate solutions during challenging times.”

The Carlsbad Desalination Plant is the largest, most technologically advanced and energy-efficient desalination plant in the nation. The plant has produced more than 90 billion gallons of drinking water for San Diego County since operations began in December 2015. Starting Sunday, Sept. 4, the plant ramped down operations, making an additional 9 megawatts of power available for other uses.

Pumped energy storage

In addition, the Water Authority and the City of San Diego are collaboratively advancing the proposed San Vicente Energy Storage Facility in East County, one of the most promising pumped energy storage solutions in California. Pumped energy storage projects are designed to store excess renewable energy from solar and wind during the day, and then discharge that energy when energy use spikes or renewable energy is not available. As proposed, the project could store 4,000 megawatt-hours per day of energy (500 megawatts of capacity for eight hours), which is enough energy to provide approximately 135,000 homes with power.

Energy reliability, water reliability

The Carlsbad Desalination Plant eliminates the need to transport water from Northern California to the San Diego region, offsetting approximately 190,000 megawatt-hours of electricity and 68,000 tons of carbon emissions each year. The plant also uses energy recovery devices that save an estimated 146 million kilowatt-hours and reduce carbon emissions by 42,000 metric tons every year.

“This is an example of how desalination plants can help contribute to energy reliability, in addition to water reliability, by taking appropriate action to increase the available energy capacity during the extreme heat event,” said Channelside President, Sachin Chawla. “We’re proud to do whatever we can to help our region address the current energy shortage.”

At his office whiteboard on this dam town’s desert edge, the water utility manager recited the federal government’s latest measures of the colossal reservoir that lay 4 miles down the road, then scrawled an ominous sketch showing how far it has shrunk.

In his stylized drawing of Lake Powell, the surface lapped just above where he marked his town’s drinking water pipe, bringing the Colorado River drought crisis uncomfortably close to home.
