California Agencies Release Draft Water Resilience Portfolio

Three California state agencies today released a draft water resilience portfolio intended to help the state manage more extreme droughts and floods, aging infrastructure, declining fish populations and other challenges.

The California Natural Resources Agency, California Environmental Protection Agency and Department of Food and Agriculture developed the draft to fulfill Governor Gavin Newsom’s April 29, 2019 executive order calling for a portfolio of actions to ensure the state’s long-term water resilience and ecosystem health.

“The portfolio approach to water supply reliability is a significant advance in how our most precious resource is managed statewide, in line with our long-term strategy in San Diego County,” said Sandra L. Kerl, general manager of the San Diego County Water Authority. “As we review the details of the new plan, we will continue collaborating with the state agencies and other partners to turn this vision into a reality that benefits our region.”

State agency leaders tour water infrastructure in San Diego County

Several state officials visited San Diego County on July 18, 2019 to assess the region’s water projects as part of their role in developing a water portfolio strategy for the state.

Natural Resources Secretary Wade Crowfoot, Deputy Natural Resources Secretary Thomas Gibson, State Department of Food and Agriculture Secretary Karen Ross, and State Water Resources Board Chair E. Joaquin Esquivel got a first-hand look at investments to diversify the region’s water supply, including the San Vicente Reservoir, Olivenhain Reservoir, and the Claude “Bud” Lewis Carlsbad Desalination Plant.

“San Diego is a great example of the challenges and complexities of managing water supply, as we look to supercharge water resiliency in California,” said E. Joaquin Esquivel, Chair, Calif. State Water Resources Control Board, after the July tour of water infrastructure.

Newsom’s order directed his administration to “identify and assess a suite of complementary actions to ensure safe and resilient water supplies, flood protection and healthy waterways for the state’s communities, economy and environment.”

Draft Water Resilience Portfolio encourages ‘collaboration within and across regions’

“This draft portfolio has been shaped to provide tools to local and regional entities to continue building resilience and to encourage collaboration within and across regions,” said Natural Resources Secretary Wade Crowfoot in a news release from the three agencies. “At the same time, state government needs to invest in projects of statewide scale and importance and tackle challenges beyond the scope of any region. Taken together, the proposed actions aim to improve our capacity to prepare for disruptions, withstand and recover from shocks, and adapt from these experiences.”

The draft release comes after several months of public input, and listening sessions, including comments from the San Diego County Water Authority and its 24 member agencies.

Draft Water Resilience Portfolio outlines more than 100 integrated actionable recommendations in four broad areas:

  • Maintain and diversify water supplies

    State government will continue to help regions reduce reliance on any one water source and diversify supplies to enable flexibility amidst changing conditions. Diversification will look different in each region based on available water resources, but the combined effect will strengthen resilience and reduce pressure on river systems.

  • Protect and enhance natural ecosystems

    State leadership is essential to restore the environmental health of key river systems to sustain fish and wildlife. This requires effective standard-setting, continued investments, and more adaptive, holistic environmental management.

  • Build connections

    State actions and investment will improve physical infrastructure to store, move, and share water more flexibly and integrate water management through shared use of science, data, and technology.

  • Be prepared

    Each region must prepare for new threats, including more extreme droughts and floods and hotter temperatures. State investments and guidance will enable preparation, protective actions, and adaptive management to weather these stresses.

Major Reser

To develop the portfolio, state agencies conducted an inventory and assessment of key aspects of California water, soliciting broad input from tribes, agencies, individuals, groups, and leaders across the state.

“From Northern California to the Central Valley and the South, Californians from cities, farms, and other sectors are working together to develop innovative solutions to the climate-related water challenges that the state is already experiencing and that are expected to worsen,” said California Environmental Protection Agency Secretary Jared Blumenfeld. “This draft portfolio is an important step toward building resilience to ensure the long-term health of our water supplies and ecosystems.”

Public comments on draft portfolio

The public will be able to submit written feedback on the draft portfolio through February 7. A final water resilience portfolio will be released soon after that.

“State agencies are only one set of water decision-makers in California,” California Secretary for Food and Agriculture Karen Ross said. “Continuing to improve our water systems relies on collaboration across all groups of water users and all stakeholders. Accordingly, feedback on this draft will be important to refining and finalizing our portfolio.”

Cash Rebates Increase for Grass Removal in San Diego Region

April 8, 2019

Removing grass can generate rebates of at least $2 per square foot for San Diego residents under new enhanced incentives that started this month.

As of April 1, the Metropolitan Water District is offering $2 per square foot for every square foot of grass removed from yards and replaced with sustainable landscaping.

“San Diego County homeowners and businesses know that sustainable landscapes are key to water reliability in our region,” said Joni German, who manages the Water Authority’s WaterSmart Landscape Makeover Program. “With the help of local landscape architects and designers, our WaterSmart Landscape Makeover Program gives them the knowledge and skills they need to be successful. WaterSmart landscapes are an upgrade, not a compromise.”

Infrastructure

The San Diego County Water Authority sustains a $245 billion regional economy and the quality of life for 3.3 million residents through a multi-decade water supply diversification plan, major infrastructure investments and forward-thinking policies that promote fiscal and environmental responsibility.

California officials toured some of that infrastructure in July as they worked to prepare a water resilience portfolio for the state. Our reporting on the July 18 water portfolio tour was the third most read story of 2019 on the Water News Network.

National City Firefighters Get WaterSmart with Sweetwater Authority

The National City Fire Department is learning more about the water system it relies on, thanks to some specialized training for firefighters from Sweetwater Authority staff.

Firefighters wanted to learn more about the water distribution system and where the city’s water originates. The department also wanted to review the location of Sweetwater Authority’s treatment facilities, pump stations, and learn about any areas of lower water pressure or dead-end hydrants.

The design of water distribution system facilities such as pipes, tanks, and pumps is dictated by fire protection requirements.

Sweetwater Authority Engineering Manager Luis Valdez and Director of Distribution Greg Snyder created and held three training sessions at Fire Station 34 in October and November to accommodate the department’s three shifts of 40 firefighters. 

“The training provides the opportunity to work closely with National City Fire Department, providing detailed information about the water system we manage and operate,” said Snyder. “Through this training, stronger working relationships are formed, which improves the flow of information between agencies. When communities are served by local agencies working together collaboratively it gives our community a high level of service.”

Valdez said the training benefits Sweetwater Authority and the National City Fire Department.

“Sweetwater Authority supports the fire department by designing, operating, and maintaining a reliable water system to allow the fire department to fulfill its core mission of fire protection and safety,” said Valdez. “The Authority also supports the department by providing expertise to confirm that fire protection requirements established by the fire department can be met by existing and planned water facilities.”

Valdez said the training gave firefighting personnel specific knowledge of its city’s water system, ranging from an overall perspective of the water supply, to the specific design and operational details of its water facilities and how they impact firefighters ability to protect the community.

“A fire department equipped with good knowledge of the water system that knows how to effectively coordinate with Sweetwater Authority during routine and emergency events will be more effective in providing fire protection and safety for its customers,” said Valdez.

Ongoing communication with Sweetwater Authority personnel during an incident response can offer firefighters options to improve distribution system operations. Depending on the nature of the emergency, coordinated responses may range from system operation changes to the mobilizing of emergency power generations to keep facilities in service.

New Oxygenation System to Improve Reservoir Water Quality

The City of San Diego’s Public Utilities Department last week took a major step toward completing an innovative project to improve water quality in Lake Hodges. A newly installed oxygenation system, designed by city engineers, will introduce highly oxygenated water to the bottom of the reservoir to reduce the accumulation of excess nutrients and harmful algae growth.

The increase of nutrients and algae in the water has been caused by human activities in the watershed upstream of the reservoir, including residential and commercial development, agriculture, and land clearing. Degraded water quality can restrict the ability to move water in and out of the reservoir.

“The ‘Speece cone’ is a fairly unique method for adding oxygen to a reservoir – there are only a few of them in the world,” said Jeff Pasek, project manager at the City of San Diego Public Utilities Department. “This project derived from a planning study that was done about five years ago, which identified oxygenation using the ‘Speece cone’ as being the most cost-effective way of addressing the water quality problems in Hodges.”

Last week, the 130,000 pound cone – named after the inventor of the technology, Richard Speece – was lowered eighty feet to the bottom of the reservoir.

Streamlined operation for maximum efficiency

The precisely coordinated operation involved lifting the 20-foot tall stainless steel cone with a large crane, while simultaneously driving a barge out from underneath. Once the cone was lowered into the water, divers headed to the bottom of the reservoir to unhook the cone from the crane, check to make sure it settled in the correct spot, and fasten it down.

In order to build a solid foundation underwater, crews excavated approximately 11 feet of silt from the bottom of the reservoir and constructed a concrete base. Before submerging the cone, crews installed and tested a pump that will move water through the cone. A large diffuser pipe was then lowered and connected to the cone by divers. The diffuser will distribute the oxygen-rich water throughout the reservoir.

Now underwater, the cone will distribute oxygen-rich water throughout the reservoir to reduce the accumulation of excess nutrients and prevent harmful algae growth. Image: Water Authority

Local and regional benefits at Hodges Reservoir

Hodges Reservoir is owned and operated by the City of San Diego, and it serves the San Dieguito Water District and the Santa Fe Irrigation District. It is connected to the San Diego County Water Authority’s Olivenhain Reservoir as part of the Emergency & Carryover Storage Project, which is designed to ensure regional water reliability in case of emergencies or if the region is cut off from imported water supplies.

“There are multiple benefits to this project – first and foremost being the water quality improvements for Hodges Reservoir,” said Goldamer Herbon, a senior water resources specialist at the Water Authority. “Ancillary benefits include operational flexibility for regional supply benefits and preventing the accumulation of mercury, which can be harmful to people and wildlife that eat fish from the reservoir.”

The California State Department of Water Resources awarded the City of San Diego a $3.4 million grant funded by the San Diego Integrated Regional Water Management program to complete the oxygenation project, which began in February 2019.

Board Supports Countywide Vote on Potential Member Agency Detachment

The San Diego County Water Authority’s Board of Directors last week authorized actions to seek to ensure all San Diego County voters are heard on plans by the Rainbow and Fallbrook water agencies to leave the regional water wholesaler and instead join a Riverside County water agency.

The Board of Directors approved a resolution to ask the San Diego Local Agency Formation Commission – known as San Diego LAFCO – to require approval by voters across the Water Authority’s service area of any proposed “detachment” by the Rainbow Municipal Water District and the Fallbrook Public Utility District from the Water Authority. Detachment from the Water Authority has potential impacts for water agencies, fire districts and water ratepayers across San Diego County.

After Wet Winter, Why is Tijuana Running Low on Water?

Water shutoffs aren’t uncommon in the growing cities of Tijuana and Rosarito. But they’re rarely announced beforehand, and they’re often isolated to certain neighborhoods after pipes or pumps fail.

Earlier this month, however, Tijuana officials announced that it was planning wide-ranging shutoffs for the next two months, in an attempt to replenish a vital reservoir that is perilously low.
