Value of Water-Mission Trails-FRSII-Underground reservoir

Value of Water: Mission Trails FRS II

/in , /by

What does project do?

The Mission Trails Flow Regulatory Structure II Project, or FRS II, will be an underground concrete water tank in Mission Trails Regional Park that will store slightly less than five million gallons of water and be used to balance flows in the aqueduct system. FRS II will be the second underground water tank in the park – both work to efficiently move water through the region. Construction is underway and expected to be completed in 2022.

Why is this project important?

Improving the region’s water infrastructure ensures that San Diego County residents are getting a clean, safe, and reliable supply. The FRS II project is another example of the successful long-term strategy by the Water Authority and its 24 member agencies to diversify its water resources, make major upgrades in the regional water delivery and storage system, and improve water-use efficiency.

How do water ratepayers benefit?

The underground reservoir is being constructed within the park to improve the Water Authority’s untreated water system in the northwest area of the park. The upgrade will increase reliable water delivery to treatment plants that serve the central and south sections of San Diego County.

In 2013, the Water Authority finalized the Regional Water Facilities Optimization and Master Plan Update, the agency’s roadmap for infrastructure investments through 2035. This updated plan focuses on optimizing the Water Authority’s existing infrastructure while maintaining the flexibility to adjust to a range of future water supply needs.

Notable

Once complete, the dirt hill will be leveled to its previous contours and revegetated with native plants – many seeded from plants within the park itself. The reservoir will be completely underground – out of sight – but within the control of the San Diego County Water Authority.

“The San Diego County Water Authority is building a massive 5-million-gallon concrete water storage tank, called a flow regulatory structure. You will never see it once it’s completed.” — Joe Little, Reporter, NBC 7, April 9, 2021.

The long-term drought and effects of climate change means more trouble for the millions of people that depend on the Colorado River.

In a statement released in early April, the Arizona Department of Water Resources, and the Central Arizona Project state that they expect the first-ever shortage declaration for the river in 2022, meaning substantial cuts to Arizona’s share of the water supply.

San Diego County’s Climate Future

/in , /by

Climate change and drought will impact San Diego County’s climate future, but regional water supply planning and adaptation measures will ensure a safe, reliable supply for the region.

Water supply strategy was one of the key points participants learned about during a Monday panel discussion, “San Diego County’s Climate Future,” hosted online by the San Diego County Water Authority, Citizens Water Academy, Leaders 20/20 and San Diego Green Drinks.

Panel moderator Kelley Gage, Water Authority Director of Water Resources, kicked off the climate conversation by describing the investments and steps taken by the Water Authority and its 24 member agencies to secure the region’s water future.

Water supply and San Diego County’s climate future

“Since our founding more than 75 years ago, our mission in partnership with our 24 member agencies is to ensure a clean and reliable supply of water for the region,” said Gage. “As part of that mission we’re involved in partnerships like the one that we have today and the research to ensure that we have planned for the impact of climate change in our water supplies.”

Gage said the Water Authority has developed a climate action plan.

“As part of our strategic planning we have developed a climate action plan which is an interdisciplinary effort to promote and coordinate implementation of climate change strategies and related activities across the Water Authority,” said Gage. “We have reached our goals for 2020 and we are on track for our 2030 goals.”

Atmospheric rivers and water management

The Water Authority partnered with the Scripps Institution of Oceanography, Center for Wester Weather and Water Extremes, at UC San Diego in 2020 to better predict atmospheric rivers and improve water management before, during, and after those seasonal storms. The Center and its partners share best practices in forecast-informed reservoir operations, increased research around atmospheric rivers and droughts, and develop strategies for mitigating flood risk and increasing water supply reliability.

Forecast Informed Reservoir Operations

Stored water releases

Marty Ralph, Researcher in Climate, Atmospheric Science & Physical Oceanography at Scripps Institution of Oceanography, and Director of the Center for Western Weather and Water Extremes, opened the panel with information on advanced research around atmospheric rivers.

Atmospheric rivers are long narrow bands of airborne water vapor, providing up to half the annual precipitation and mountain snow that is key to California’s water supply. New research allows reservoir operators to use atmospheric river forecasts to better predict storm events and prevent unnecessary stored water releases.

“This stored water has helped to cope with the third driest year on record for the region,” said Ralph.

Atmospheric Rivers

Atmospheric rivers more “impactful” with climate change

Another Scripps Institution of Oceanography researcher, Alexander “Sasha” Gershunov, said that California receives most the country’s extreme precipitation events due to atmospheric rivers. Low and medium intensity precipitation events are predicted to decrease, while high intensity precipitation events are predicted to increase, especially in California.

“With warming, atmospheric rivers get stronger, wetter, longer, and more impactful, and they also produce more of our annual precipitation total,” said Gershunov. “There are many implications of these changes from water resources management, to wildfires, to debris flows.”

San Diego Regional Climate Collaborative

Darbi Berry, Program Manager at the San Diego Regional Climate Collaborative, described projects moving forward in the region to address equity issues related to water availability and pollution. Advancing the Nexus of Water and Equity looks at how different communities are impacted by a changing climate.

Increased variability in rainfall events and the potential for flooding in the San Diego region is a contributing factor to ongoing water quality issues in disadvantaged neighborhoods. One project carried out to address these equity issues is the National City, Paradise Creek project which re-graded a creek that was continuously overflowing and causing flood damage during atmospheric river events.

By the time this column is published, Northern California may be receiving some much-needed rain, and possibly some snow. However, late-season precipitation does not change the reality that California is in one of its periodic droughts after two dry years.

Major Northern California reservoirs are only about half-full due to scanty runoff from mountain snowpacks, farmers are getting tiny percentages of their normal water allotments, and local water agencies are beginning to impose restrictions on household use.

California water officials on Friday issued a draft order telling Nestlé to “cease and desist” taking much of the millions of gallons of water it pipes out of the San Bernardino National Forest to sell as Arrowhead brand bottled water.

The order, which must be approved by the California Water Resources Control Board, caps years of regulatory probes and a public outcry over the company’s water pipeline in the San Bernardino Mountains, where opponents argue that siphoning away water harms spring-fed Strawberry Creek and the wildlife that depends on it.
