All Set for Carlsbad Dredging Project

Carlsbad beaches will soon have more sand as a result of the Agua Hedionda Lagoon dredging project – starting this February until mid April, informs the City of Carlsbad, California. The lagoon has been dredged every one to four years since 1954 as part of the Encina power plant operations. The last time the lagoon was dredged was three years ago, in 2018. Now that the Encina plant has been retired, Poseidon Water is taking over the dredging, as part of an agreement when the seawater desalination plant was built and came online in 2015.

A Tale of Two Coastlines: Desalination in China and California

The port city of Tianjin is in desperate need of water. The surface and groundwater supplies of this sprawling northeast Chinese metropolis have shrunk to dangerously low levels due to decades of reduced rainfall and overexploitation of the Hai River that flows through the city. According to the Tianjin Environmental Protection Bureau, the city’s per capita water resources are one-twentieth of China’s national average, far below the UN benchmark for a water-stressed region. Despite promoting water conservation and metering among residential and industrial users, Tianjin still faces shortages that drive its reliance on large-scale water-supply infrastructure like the South-North Water Transfer Project and seawater desalination. 

In the United States, a similar situation is unfolding. After a prolonged drought between 2011-2015, California’s investment in desalination solutions to supply fresh water to the state’s dry south grew exponentially. While most American desalination plants are used to purify less-saline “brackish water” from rivers and bays, large-scale seawater operations have begun to proliferate in California, as well as Florida and Texas. California alone has 11 municipal seawater desalination plants, with 10 more proposed. Southern California-based Poseidon Water LLC opened America’s largest desalination facility in Carlsbad in 2015, which currently meets about 10 percent of San Diego’s water demand. With the capacity to produce 54 million gallons of water a day, this new desalination plant, as well as another one currently in the works at Huntington Beach, could ensure water security in Southern California.

Water Company Withdraws Desalination Proposal as Battle over Environmental Justice Heats Up

Amid mounting controversy and concerns over environmental justice, California American Water on Wednesday withdrew its application for a desalination project in the small Monterey Bay town of Marina.

The proposal had become one of the most fraught issues to come before the California Coastal Commission, which was set to vote Thursday. The decision would have been the first major test of the commission’s new power to review not only harm to the environment when making decisions but also harm to underrepresented communities.

Conservationists Split Over Poseidon Desal Project’s Potential to Help Bolsa Chica Wetlands

Along a Huntington Beach coastline dotted with oil rigs and a power plant, one of California’s largest remaining saltwater marshes has been a source of pride for local environmentalists.

But the marsh, known as the Bolsa Chica Wetlands, is endangered despite a years-long struggle to pull together sufficient public funding for its upkeep.

Nearby, the Poseidon Water Co., which has been in a decades-long, controversial fight to build a seawater desalination plant next to the AES energy station at the south end of the city, has justified its project partly with a promise to finance the wetlands’ conservation.

Pure Water Monterey Supply Set for Extraction, Use on Peninsula

Pure Water Monterey is finally poised to make water available for the Monterey Peninsula, providing a new water supply source for the area while allowing a reduction in Carmel River water usage albeit at a considerably reduced rate to start than was expected.

Last weekend, Monterey One Water announced that it had completed a 1,000-acre-foot recycled water reserve in the Seaside basin and that California American Water could start extracting additional water from the basin equivalent to the amount of recycled water being pumped into the basin beyond the reserve.

Water: Coastal Commission Staff Again Advises Desal Project Denial

Nine months after the Coastal Commission conducted its first hearing on California American Water’s proposed desalination project, commission staff has again recommended denial of the project in favor of a Pure Water Monterey expansion proposal.

On Tuesday, commission staff released a 154-page staff report essentially reiterating its previous arguments against the Cal Am desal project, including its relative cost, environmental impact and controversial nature. It touted the “feasible and environmentally preferable” recycled water project as a viable alternative in the Monterey Peninsula’s long-running attempts to develop a replacement water supply to offset the state ordered Carmel River cutback order.

Opinion: Poseidon’s Huntington Beach Desalination Plant Still In Choppy Waters

As Poseidon Water pursues the final government approvals needed to build one of the country’s biggest seawater desalination plants, the company still cannot definitively say who will buy the 50 million gallons a day of drinking water it wants to produce on the Orange County coast.

Public Argues For, Against Huntington Beach Desalination Plant, Decision Near

The 20-year battle between seawater desalters and Orange County environmentalists and community activists neared a turning point Thursday, the first in a series of final public hearings around a Huntington Beach desalination plant proposal before local regulators.

Hearings and public comments at the state regional water board started Thursday, are continuing today, and could continue to Aug. 7, if needed, with a vote on the required permits for the $1 billion water desalting project planned at the end of the hearings.

Proposed by the Poseidon Water company, the project has become one of the largest battles over Orange County’s coastline in decades.

Controversial Poseidon Desalination Plant in Huntington Beach Set for Hearings This Week

Poseidon Water’s seawater desalination plant in Huntington Beach, first proposed in 1998, could be getting closer to beginning construction after more than two decades.

Poseidon’s Desalination Plant Faces Day of Reckoning

After more than 20 years of developing plans for a Huntington Beach desalination plant and winding its way through a seemingly endless bureaucratic approval process, Poseidon Water comes to a key juncture as the Regional Water Quality Control Board votes on whether to grant a permit after hearings this week.
