Opinion: California Can Solve its Water Shortage With the Water We Have. Here’s How

/in , , /by /CalMattersby Heather Cooley

California is at a water crossroads.

We can continue our costly, 100-year-old pattern of trying to find new water supplies, or we can choose instead to focus on smarter ways of using – and reusing – what we already have.

The cheapest water is the water we save.

RE:BORDER 2019 Seeks Transborder Solutions For Water Issues

/in , /by

A two-day conference in San Diego and Tijuana seeks to forge regional solutions for cross-border water issues by breaking down academic, political and administrative boundaries.

The theme of RE:BORDER 2019 is “The Water We Share.” RE:BORDER is a new initiative from San Diego State University President Adela de la Torre that each year will examine a significant transborder issue of the California-Baja California border region in partnership with our Mexican university and community collaborators.

The binational conference kicks off at San Diego State University at 9 a.m. on November 25 and continues the next day at the Universidad Autónoma De Baja California (UABC) in Tijuana.

Water industry officials and elected leaders from the U.S. and Mexico will join university researchers for a series of panel discussions that explore how SDSU, UABC, and regional partners – including the San Diego County Water Authority and its 24 member agencies – can contribute to innovative solutions for water-related challenges in the transborder region.

Water knows no borders

“When we think about water in every dimension, whether it’s the ocean, to the rivers, to the creeks across the Tijuana River Watershed, there are no borders,” said SDSU President Adela de la Torre. “The conference is a first step toward creating solutions that allow both countries to be collaborative and learn from each other.”

San Diego Mayor Kevin Faulconer will deliver opening remarks at SDSU followed by a special presentation by San Diego County Water Authority Board Chair Jim Madaffer. California State Water Resources Control Board Chair E. Joaquin Esquivel is scheduled to deliver the keynote address. State Senator Juan Vargas will close the first day of the conference.

“Water issues and challenges require collaboration on both sides of the border to reach solutions that transcend political boundaries,” said Water Authority Board Chair Jim Madaffer. “The Water Authority and its 24 member agencies continue to develop local projects and explore opportunities that benefit the region, including Mexico and the Southwest.”

Cross border water challenges and solutions

Water reuse, access to a safe water supply, and the political and administrative boundaries in the transborder region are among the topics for discussion at SDSU.

Water Authority Assistant General Manager Dan Denham is one of several panelists who will explore transborder water challenges from the perspectives of regional stakeholders such as farmers, local and state agencies and environmental groups.

Elsa Saxod, a Water Authority board member representing the City of San Diego, will participate in a panel session that looks at the binational management of the Tijuana River Watershed.

Climate change and the transborder region

Topics for Day 2 of the conference in Tijuana include climate change, water security and risks, water and food, and water and equity.

The sessions will examine how the transborder region will be affected by climate change – including greater risks of floods, landslides and wildfires – how reduced water for agriculture impacts the region, and on-going concerns about uneven access to water resources.

“Tijuana and San Diego form a region closely linked by their economies, societies and culture,” said Natanael Ramírez Angulo, director of the Faculty of Economics and International Relations at UABC. “Understanding the problems and challenges involved in the management and use of water, an essential natural resource, must be a priority not only for governments but also for society itself, and we believe that universities can provide valuable knowledge that can help generate programs and policies that help local and federal governments to be successful in addressing this issue.”

Pure Water Oceanside Project Construction Slated For 2020

/in , /by

The City of Oceanside is joining the City of San Diego and East San Diego County in adding advanced purified water to its drinking water supply. The Pure Water Oceanside project is expected to break ground next spring and begin producing advanced purified water in 2022.

The Padre Dam Municipal Water District, Helix Water District and the City of San Diego, are among the water agencies in San Diego County that are developing or expanding water recycling to increase the local water supply.

The Oceanside project launched in March with a “World of Water” community open house attended by more than 400 people. Building on the interest generated at the event, the city opened its doors for the public, schools and scouts to experience Pure Water Oceanside on October 15. The next community event is scheduled for November 9.

“The incredible interest, success and feedback from the community event demonstrated a true thirst for water knowledge and a strong desire to see, first-hand, water facilities located in the community,” said Cari Dale, water utilities director for the City of Oceanside. “Pure Water Oceanside is an important and smart investment and we find tremendous value in educating the public about the importance of diversifying the city’s water supply.”

The tours offer a behind-the-scenes look of the San Luis Rey Water Reclamation and Mission Basin Groundwater Purification Facilities, where guests can take a hands-on approach and learn about the technology used to recycle and purify water.

Pure Water Oceanside will purify recycled water to create a new local source of high-quality drinking water that is clean, safe, drought-proof and environmentally sound. The project will produce enough water to provide 32% of the city’s water supply, or between 3 and 5 million gallons of water per day.

In addition to tours, Oceanside has developed a comprehensive public education program for the water purification project, including a video, fact sheet, FAQ and community group presentations. To experience Pure Water Oceanside and sign up for an upcoming tour, go to: www.PureWaterOceanside.org.

EPA Action Plan to Boost Water Reuse Across U.S.

/in , /by

The U.S. EPA today released a draft plan to advance water reuse nationally at the WateReuse Association Symposium in San Diego.

The National Water Reuse Action Plan identifies 46 proposed actions organized around 10 strategic objectives, including leadership and collaboration, to support the implementation of water reuse.

“Forty states anticipate experiencing fresh water shortages in certain regions within their borders over the next decade,” said David Ross, EPA’s assistant administrator for water. “Diversifying our nation’s water portfolio must be a nationwide priority, and water reuse has the potential to ensure the viability of our water economy for generations to come.”

The draft plan incorporates federal, state, tribal and local water perspectives and highlights key actions that support consideration and implementation of water reuse.

The San Diego County Water Authority and its 24 member agencies have worked for decades to increase the region’s water supply reliability through supply diversification, and the Water Authority collaborated with its member agencies to submit comments to the EPA before the draft was released.

National Water Reuse Action Plan a ‘game changer’

The draft plan will be open for public comment for 90 days following its publication to the Federal Register. During that period, EPA will solicit feedback about how to prioritize and implement the proposed actions.

EPA’s goal is to issue a final plan that will include clear commitments and milestones for actions that will further water reuse to bolster the sustainability, security and resilience of the nation’s water resources, according to the agency.

“The National Water Reuse Action Plan will be a game changer,” said Patricia Sinicropi, executive director of the WateReuse Association. “Communities across the country are incorporating water reuse into their water management strategies as a proven method for ensuring a safe, reliable, locally controlled water supply – essential for livable communities, healthy environments, robust economies and a high quality of life.”

“California is widely recognized as a national and world leader in water recycling,” according to the California WateReuse Action Plan, released in July 2019. “Recycled water supplies offset approximately 9% of the state’s urban water demands and agricultural reuse provides reliable water supplies for farmers throughout the state.”

In July, the Water Authority Board endorsed Governor Gavin Newsom’s Executive Order N-10-19, directing development of a water resilience portfolio approach that meets the needs of California through the 21st century.

On July 18, state officials toured San Diego County water infrastructure to see the region’s successful water portfolio approach for supply diversification, as they work to create the statewide water resilience portfolio.

Where Water Is Scarce, Communities Turn To Reusing Wastewater

/in , /by /Yale Environment 360 (New Haven, Conn.)by Jacques Leslie

Then California’s Orange County Water District began distributing drinking water derived from sewage in the mid-1970s, it acted out of simple need. The aquifer it relied on for most of its drinking water had been so overdrawn that saltwater from the nearby Pacific Ocean was seeping into it, and allocation limits prevented increases in exports from the Colorado River and Sierra Nevada Mountains, sources of the rest of the district’s water. Orange County was then a bastion of political conservatism, not the sort of place associated with environmental innovation, but water scarcity is a powerful motivator.
