Students-Student displays science and engineering fair project

San Diego County Students Innovate to Solve Water Challenges

In March, Water Authority staff judged water-related projects by students at the 67th annual Greater San Diego Science and Engineering Fair. Judging the fair is a longstanding tradition at the Water Authority and a component of the education outreach program. For decades, the Water Authority has recognized the top water-related projects with a scholarship and award. This year’s fair was conducted in a virtual format, but more than 280 students still brought their best projects to the table.

Each student who was interviewed by Water Authority staff demonstrated a strong knowledge of the scientific process, as well as an awareness of big picture issues that are important in the water industry and beyond. Five winners were selected, and each will receive a gift card and plaque. Water Authority staff also showcased a video of the five winners and their outstanding projects at the April San Diego County Water Authority Board of Directors meeting.

Students present top water-related projects

Forward-thinking students solve global and everyday water issues

In the senior division, first place winner Bella Rose Schremmer designed a piston-buoy rack and pinion wave energy converter device. The 10th grader from University City High School said she was inspired by the kinetic energy formed by ocean waves, and she wanted to create a project that could capture that energy as a renewable energy source to replace the burning of fossil fuels. Bella Rose attributed part of her success in this project to her father, who supported her by procuring materials and providing encouragement, and to her teacher and mentor, Mrs. Bosch, who guided her through the process.

In second place, Suvali Sengupta created a biodegradable microporous polymer that was designed to help soil water retention in an agricultural setting. The 11th grader from Westview High School shared that her inspiration came from her Indian heritage and the drought conditions that India’s farmers struggle with each year.

Saltwater desalination, water purification, water conservation

In the junior division, Kristine Talaga from St. Gregory the Great Catholic School won first place with her project on saltwater desalination. The 7th grader designed a project to test the effects of different colored backgrounds – black, white or foil – on containers containing salt water and how quickly heat could desalinate the water in each container.

Samantha Rivera, an 8th grader from Chula Vista Middle School, claimed second place with her project about which methods of water purification removed the most dissolved solids.

In third place, 8th grader Sonria Rheiglene Simanski, also representing Chula Vista Middle School, tracked how much water is wasted when waiting for the shower to warm up, determining the best times of day to shower for optimal water-use efficiency.

Opinion: Innovation Needed to Solve State’s Water Challenges

Earlier this month, camera crews once again gathered in the Sierra Nevada to watch a man plunge a pole through the snow. The pole was removed and, following a tense few moments, Californians learned we experienced another dry winter, and we are plunging further into drought. These snowpack surveys are quaint rituals, but they’re also a jarring reminder of how little technological innovation has occurred in California’s water sector.  The case for action is clear.

Vallecitos Water District Recognized for Innovative Technology at Mahr Reservoir

The Vallecitos Water District received two awards for its innovative use of technology to reduce algae blooms at the Stanley A. Mahr Reservoir in San Marcos.

The district received the “Excellence in Action” award from the national WateReuse Association, and the “Innovation and Resiliency” award from the California Association of Sanitation Agencies, or CASA.

The WateReuse Association is the nation’s only trade association solely dedicated to advancing laws, policy, funding, and public acceptance of recycled water. CASA provides leadership, advocacy, and information to its members, legislators, and the public. CASA also promotes partnerships on clean water and beneficial reuse issues that protect public health and the environment.

Known for its sustainable practices in water and wastewater treatment processes without compromising water quality, Vallecitos Water District employs a new ultrasound technology to improve water quality at the Mahr Reservoir and reduce the need for chemical treatment.

“These awards are proof of the Vallecitos Water District’s commitment to innovation,” said Vallecitos Board President Mike Sannella. “District staff are to be commended for their efforts to use innovative technology to improve and enhance our operations.”

Algal blooms treated with sonic technology

Originally called La Costa Storage No. 1 Dam and Reservoir when completed in 1981, Mahr Reservoir was renamed after original founder and 35-year board member Stanley A. Mahr. It stores up to 54-million gallons of reclaimed water for irrigation use. Vallecitos Water District has contracts with the City of Carlsbad and Olivenhain Municipal Water District to provide as much as five million gallons of recycled water daily as needed.

Because the reservoir’s location receives intense sunlight with little rain, algal blooms can occur in the nutrient-rich recycled water. Algal blooms are commonly treated with costly chemicals that are labor-intensive to apply. Vallecitos Water District uses technology developed by LG Sonic of the Netherlands. It provides a complete overview of reservoir water quality, allowing swift identification and treatment of algal blooms.

Every ten minutes, an MPC Buoy in the Mahr Reservoir measures and monitors green and blue-green algae population, pH, turbidity, dissolved oxygen, and water temperature. The data is collected in real time and uploaded online software, which uses the data to predict algal blooms three to ten days in advance.

Sound barrier limits algae

The LG Sonic buoy can create a sound barrier in the top water layer. It affects the algae buoyancy, preventing it from rising where it can absorb sunlight to grow. Starved of sunlight and nutrients, algae cells sink to deeper water where they degrade due to natural bacteria and do not release toxins into the water.

With overall algae levels reduced through sonic technology, the need for chemical treatment is also reduced. LG Sonic’s specific low-power ultrasonic transmitters emit signals which are not harmful to people, fish, plants, or other wildlife.

Building a Collaborative Vision for San Diego County

We welcome the new year with heavy hearts about the recent events in our nation’s Capitol and a renewed commitment to civility and respect at every level of government.

At the same time, we are maintaining our concentration on our priorities for the year, which are numerous and significant. I’m focused on advancing San Diego County’s interests as we continue to fulfill our mission of making sure that our region has safe and reliable water supplies at an affordable price, which is critical to maintaining our economic competitiveness and sustaining our wonderful quality of life.

Here’s some good news about how the Water Authority is putting San Diego County first in 2021:

  • As part of our commitment to meeting some of the strictest environmental regulations in the world, the Water Authority and Poseidon Water have launched a state-of-the-art project evaluating intake screen technologies at the Claude “Bud” Lewis Desalination Plant, which has served more than 65 billion gallons of locally produced water over the past five years. Crews are testing both active screen and passive screen technologies in Agua Hedionda Lagoon to complete the full-scale project by the end of 2023.
  • We are updating our Urban Water Management Plan, which is a critical part of meeting the long-range water needs of the San Diego region for both normal years and dry years. This planning document is increasingly important given the increasingly unpredictable impact of climate change. The planning process is, of course, a collaborative effort with our 24 member agencies as we account for their local supplies and demand projections.
  • Our low-cost supplies of conserved water from the Imperial Valley are the foundation of our diversified supply portfolio. With Board direction, staff has launched the next phase of a study to explore a new system to deliver those supplies because initial studies show it could be most cost-effective than the current system and mutually beneficial for our partners in the valley. The study will only advance if it benefits the region by providing cost savings for ratepayers.
  • As the regional economy recovers, we are working hard to protect ratepayers by maintaining a focused and strategic budget. It’s a tough balance, but we are working hard to find the right combination of near-term and long-term funding priorities in these challenging times.
While I’m glad to put the old year behind us and welcome 2021, I’m certain there will be many challenges and opportunities ahead. I’m committed to keeping you informed along the way, and to working with our Board, member agencies, stakeholders, regional leaders and ratepayers to create innovative solutions. In my 20-plus years on the Water Authority Board, we’ve never shied away from big and bold ideas – and 2021 will be no exception.

Is Farming with Reclaimed Water the Solution to a Drier Future?

On a Saturday in late October, Carolyn Phinney stands hip-deep in a half acre of vegetables, at the nucleus of what will one day be 15 acres of productive farmland. “You can’t even see the pathways,” she says, surrounded by the literal fruits of her labors. The patch is a wealth of herbs, tomatoes, eggplants, peppers, kale, winter squash, and zucchini. So much zucchini — fruits the size of bowling pins hidden under leaves as big as umbrellas.

Port of San Diego Approves Pilot Project to Develop Rapid Stormwater Monitoring Device

The Port of San Diego has approved a pilot project with FREDsense Technologies Corp. to develop a portable five-in-one field-testing sensor device to provide real-time metals analysis for stormwater monitoring. FREDsense will utilize their pre-existing titration platform optimized for the environmental remediation industry to produce an automated testing system for stormwater analysis, which will test the levels of various metals in San Diego Bay including aluminum, copper, lead, zinc and nickel, all of which are currently manually monitored under the Port’s stormwater programs.

In Boost for Renewables, Grid-Scale Battery Storage Is on the Rise

The twin smokestacks of the Moss Landing Power Plant tower over Monterey Bay. Visible for miles along this picturesque stretch of the Northern California coast, the 500-foot-tall pillars crown what was once California’s largest electric power station — a behemoth natural gas-fired generator. Today, as California steadily moves to decarbonize its economy, those stacks are idle and the plant is largely mothballed.

Pure Water Oceanside-US EPA loan-Water Recycling

Pure Water Oceanside Recycling Project Gets $69 Million EPA Loan

The Pure Water Oceanside project is getting a $69 million loan from the U.S. EPA that will finance nearly half of the project’s construction cost.

EPA officials announced the loan at an event today in Oceanside attended by federal, regional and local officials.

The innovative water reuse project will purify recycled water to create a new source of high-quality drinking water that is clean, safe, drought-proof and sustainable. It also will benefit the environment by reducing discharges into the Pacific Ocean. Construction and operation of the plant is expected to create 622 jobs.

Scheduled to be completed in 2022, Pure Water Oceanside will be the first operating advanced water purification facility in San Diego County. The project will provide more than 32% of the City of Oceanside’s water supply, or 3 to 5 million gallons per day.

Sustainability, drought-proof water supply

“The City of Oceanside is proud to be a leader in sustainability and water reliability,” said Oceanside Mayor Peter Weiss. “Pure Water Oceanside marks the next big step for our City as the project will safeguard against drought, reduce our dependence on imported water, and create an exceptionally pure drinking water supply.”

“I appreciate the U.S. EPA in their funding support as it is a critical aspect for Oceanside’s ability to continue to improve our local water supplies while minimizing our impact to our ratepayers,” said Weiss.

Loan supports infrastructure investments

“At the City of Oceanside, we are focused not only on today, but also are committed to planning for tomorrow to ensure future generations will have access to high-quality drinking water,” said Oceanside Water Utilities Director Cari Dale. “This loan will be instrumental in moving our Pure Water Oceanside project forward to completion and aligns with our long-term goal to have 50% of our city’s water supply be locally sourced by 2030.”

The Water Infrastructure Finance and Innovation Act (WIFIA) loan to help finance the Pure Water Oceanside Project comes at a critical time, as the federal government, EPA, and water industry work to offset the public health and financial impacts of COVID-19.

The Pure Water Oceanside project is estimated to cost $158 million, and the WIFIA loan will finance nearly half of that cost, according to the EPA. The remaining project funds will come from a combination of grants, water system revenue backed obligations, and system funds.

“EPA’s support for this project illustrates two agency priorities as we work to meet 21st century water demands — reusing the water that we have and revamping our nation’s water infrastructure,” said EPA Assistant Administrator for Water David Ross. “With WIFIA’s support, Pure Water Oceanside will be a landmark project as EPA looks to foster additional innovative water reuse strategies and infrastructure investments across the country.”

“I am proud and excited for the City of Oceanside and everyone who has worked so hard on the Pure Water Oceanside project,” said Congressman Mike Levin, who represents north San Diego County. “Now more than ever, it’s critically important that we diversify our water supply. Thanks to Pure Water Oceanside, the City of Oceanside, and this EPA loan, we are one step closer to achieving that independence. This is an extraordinary milestone and will make a huge difference for countless families in North County.”

National Water Reuse Action Plan

The water reuse benefits of the project highlight commitments made under the National Water Reuse Action Plan—a collaborative effort and the first initiative of its magnitude aimed at strengthening the sustainability, security and resilience of our nation’s water resources. The Action Plan frames the business case that water reuse is a viable and growing means of supporting our economy and improving the availability of freshwater for farmers, industry, communities, and ecosystems.

“By improving water infrastructure, we are improving the quality of life and public health in our communities,” said EPA Pacific Southwest Regional Administrator John Busterud. “Through the WIFIA loan program, EPA is happy to support the Pure Water Oceanside Project in ensuring access to clean and safe drinking water for decades to come.”
