Encina Power Station Demolition Begins

NRG Energy began demolition of the 400-foot Encina Power Station stack this week. The apparatus mounted around the top of the stack, known as the Mende Spider, is equipped with a jackhammer that breaks the concrete in a cylindrical pattern; the pieces of the stack fall through the center of the stack and are recovered from the bottom. NRG estimates the device will remove the stack about 10 feet per day. At this rate, NRG anticipates removing the top 350 feet of the Encina stack by the end of April. The remaining 50 feet will be removed from the ground by an excavator.

Credit Agencies Affirm Water Authority’s Strong Ratings Despite Headwinds

All three major rating agencies – S&P, Moody’s, and Fitch – have affirmed the San Diego County Water Authority’s strong credit ratings, which will help the Water Authority optimize its debt portfolio and minimize the cost of financing important water reliability projects.

Water World: After Nearly 40 years, Peter MacLaggan Leaves a Liquid Legacy

Every time someone turns on the tap in San Diego County, out flows the work of Peter MacLaggan.

MacLaggan was the point man in the construction of the Carlsbad desalination plant, a nearly $1 billion public-private partnership that since 2015 has supplied nearly 10 percent of the potable water consumed in the county.

Desalination relies on the virtually unlimited supply of water in the Pacific Ocean. It provides a safe, reliable source of local water in a region that for many years relied on supplies from hundreds of miles away and was subject to mechanical breakdowns, seasonal shortages and the whims of nature.

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

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.

Newsom Pushes Private Seawater Desalting Plant Over Local and Environmental Opposition

When Gov. Gavin Newsom was photographed dining at an opulent Napa Valley restaurant during a surge in coronavirus cases, many Californians saw it as hypocrisy. For opponents of a planned $1-billion desalination plant along the Orange County coast, however, the optics were menacing.

The unmasked Newsom was celebrating the birthday of a lobbyist for Poseidon Water, which is close to obtaining final government approval for one of the country’s biggest seawater desalination plants.

Carlsbad Sand Dredging Project Protects Beaches, Water Supply

Heavy equipment will dominate a stretch of Carlsbad’s beach near the old Encina Power Plant for the next month.

Crews are funneling thousands of cubic yards of sand per day onto the beach, not only to protect the shoreline, but also the water supply.

Poseidon Water, which runs the desalination plant adjacent to the old power plant is running the project. The desalination plant converts 50 million gallons of ocean water to drinking water per day, providing 10 percent of the region’s water supply.

Opinion: A Desalination Skeptic Now Sees Carlsbad Plant’s “Undeniable Value”

It is no secret that I wasn’t the biggest fan of the Claude “Bud” Lewis Carlsbad Desalination Plant when it was proposed, and I still wasn’t completely on board when the plant began operations in 2015, or even when I was elected to the Carlsbad City Council in 2016.

But time has given me perspective, and I recognize now that the value that the Carlsbad Desalination Plant provides our region is undeniable.

We are now celebrating the plant’s fifth anniversary since operations began. In that time, I’ve seen firsthand how the Carlsbad Desalination Plant benefits our city and the entire San Diego region, given it has produced more than 65 billion gallons of high-quality drinking water. To put that in perspective, that is enough water to fill the Rose Bowl in Pasadena all the way to its brim nearly 200 times!

New Discovery Could Lead to Cheaper and More Efficient Water Desalination

Removing salt from seawater to make it safe to drink means overcoming a number of scientific challenges, including optimizing the membrane used for the desalination process – and new research into these membranes promises to make the whole operation cheaper and more accessible in the future.

Water News Network Top Stories of 2020

The Water News Network top stories of 2020 reflect the San Diego region’s interest in water conservation, the environment and efforts to diversify water supply sources. But the year was dominated by the coronavirus pandemic, which impacted water infrastructure and operations.

As one of essential sectors of the economy, the water and wastewater industry took added COVID-19 precautions. The essential employees of the San Diego County Water Authority and its 24 member agencies worked to ensure the continued safety and reliability of the region’s water supply. In some cases, that meant sheltering-in-place, which employees of the Claude “Bud” Lewis Carlsbad Desalination Plant did in March. For agencies operating multiuse recreational facilities, such as Lake Jennings, the pandemic also caused frequent schedule changes.

To reassure users about the safety of the water supply, the Water Authority and its member agencies shared a series of videos with the public, featuring Switchfoot’s Jon Foreman, to let people know they can “Trust the Tap.”

Top Stories of 2020

COVID-19

Reservoirs and lakes operated by water agencies in San Diego County were closed or had varying schedules due to the coronavirus pandemic. The impact of the pandemic on recreational facilities in the region was the most viewed story of 2020.

Reservoirs, Lakes Remain Closed to Fishing Due to COVID-19 Pandemic

Although San Diego County’s lakes and reservoirs remain closed to fishing and other recreational activities for safety reasons due to the coronavirus pandemic, staff and volunteers continue to work. Crews are maintaining facilities, providing security, and sharing photos of wildlife and native blooms enjoying the arrival of spring.

The City of San Diego’s reservoirs and lakes are closed due to the coronavirus pandemic. The city closed the reservoirs to the public on March 18 to protect the public and minimize the spread of the COVID-19 virus. The nine water supply storage reservoirs are operated by the City’s Public Utilities Department.

Popular overnight campsites remain open at Santee Lakes, owned and operated by the Padre Dam Municipal Water District.

“Camper well-being is important to us and Santee Lakes didn’t want to displace people,” said Melissa McChesney, Padre Dam communications manager. She said that includes long-term campers who spent winter at the lake.

At Lake Jennings, Recreation Manager Kira Haley says eight volunteers continue to live and work from their campground homes in recreational vehicles and campers. She said their days remain “pretty typical” even though they see more wildlife and not people.

New Fish-Friendly Seawater Intake Pumps at Carlsbad Desalination Plant

July 22, 2020

New fish-friendly seawater intake pumps recently commissioned  at the Carlsbad Desalination Plant are among the most environmentally advanced intake pumps in the world.

The three intake pumps, manufactured by Indar, are part of a broader effort to ensure the long-term health of the marine environment near the Claude “Bud” Lewis Carlsbad Desalination Plant, which sits on the shores of Agua Hedionda Lagoon.

Installation of the new intake pumps is part of a phased program to replace the existing seawater intake and discharge facilities with state-of-the-art technology to protect marine life that wasn’t available when the plant was operating with source water from the Encina Power Station. The closure of the power station in December 2018 led to temporary intake-discharge operations until the new intake pumps came online. The next steps include adding new intake screens, designed to prevent any sea-life larger than 1 millimeter (thicker than a credit card) from entering the plant.

Essential work during COVID-19 pandemic

The work to complete the construction and commissioning of the new fish-friendly seawater intake pumps was part of the essential work allowed under California guidelines during the COVID-19 pandemic. The contractor, Kiewit–Shea Joint Venture, worked in accordance with guidelines adopted by the State Building and Construction Trades Council and approved by Governor Gavin Newsom for essential construction. The contractor worked uninterrupted to complete the project per the June 30, 2020, deadline set by the Regional Water Quality Control Board without any health or safety violations.

First Advanced Water Purification Facility in San Diego County is On the Map

City of Oceanside officials and regional water industry leaders gathered today to break ground on Pure Water Oceanside, the first advanced water purification facility in San Diego County. The $67 million project – scheduled to be completed in 2021 – will purify recycled water sourced from the San Luis Rey Water Reclamation Facility.

“Today, we put Pure Water Oceanside on the map and are one step closer to achieving the goal of greater water-independence for our city, residents and businesses,” said Cari Dale, Oceanside’s water utilities director. “This future-focused project will provide multiple benefits by reusing our water resources to their full potential.”

Reducing dependence on imported supplies

The local project will reduce Oceanside’s dependence on imported water by more than 30%. The purification process is inspired by the natural water cycle and reduces the amount of recycled water discharged into the ocean.

The project is partially funded by the Local Resources Program through the San Diego County Water Authority and Metropolitan Water District of Southern California.

“The tremendous conservation focus, water infrastructure planning and investment by the Water Authority and its 24 member agencies has put our regional supplies in solid standing,” said Water Authority General Manager Sandra L. Kerl. “The mission of providing reliable water supplies to San Diego County can be likened to a puzzle; there are many pieces that fit together to create an overall solution. Our next increment of supply in the San Diego region is from potable reuse projects.”

Water Reuse and Recycling Top Stories in 2020

Other top stories in 2020 covered by the Water News Network included updates on several water reuse and recycling projects, including:

Pure Water San Diego

Construction of Phase 1 of the Pure Water Program is scheduled to begin in early 2021. Phase 1 will include a full-scale, 30-million-gallon-per-day Pure Water Facility that will use the five water purification steps modeled at the Demonstration Facility.

East County AWP

The East County AWP will be one of the first potable reuse projects in California to use new reservoir augmentation regulations. The program will meet up to 30% of East San Diego County’s drinking water demands, almost 13,000 acre-feet of water per year, and eliminate the discharge of 15 million gallons of partially treated wastewater into the Pacific Ocean.

Santa Margarita River project

The Santa Margarita River Conjunctive Use Project is a joint project with Marine Corps Base Camp Pendleton, and will eventually supply about 30% of the Fallbrook Public Utility District’s water, and virtually all of Camp Pendleton’s water.
