Former Gov. Jerry Brown signed Senate Bill 100 into law Sept. 10, 2018. The ambitious bill commits the state to 100% carbon free electrical energy by 2045. There are key milestones along the way: 50% renewables by 2026 and 60% renewables by 2030. California has been ramping up its renewable portfolio standard since it was established in 2002 with the goal of 20% renewable energy by 2017. Four years later, the target was adjusted to 20% by 2010 and, in 2008, the governor moved the target to 33% by 2020. In 2015, the legislature passed SB 350, setting a new target of 50% by 2030. These incremental changes have made California a world leader in renewable portfolio standard targets.

This summer, the Water Authority is partnering with three technology companies to test the condition of the agency’s oldest pipelines forming the First Aqueduct in Valley Center. Technology providers test their new and improved tools on Water Authority and member agency pipes. The tools are then used to assess the condition of those same pipes.
This efficient strategy ensures maximum condition assessment accuracy. The strategy also allows for technology to keep up with what water agencies need and minimizes costs. Targeted repairs and maintenance activities maximize the life expectancy of some of the region’s most critical infrastructure.
Industry leaders in pipeline condition assessment
The Water Authority turned to experienced contractors from the oil and gas industry to effectively and efficiently identify corrosion issues on the 70-year-old pipe:
- Pure Technologies’ regional headquarters in San Diego brought its near-field electromagnetic inspection expertise to assess low-pressure portions of the reinforced concrete pipelines using the PipeWalker® tool.
- Pipeline Inspection and Condition Analysis Corp. (PICA) from Edmonton, Alberta, assessed medium-to-high pressure zones on a similar type of pipe construction that includes an additional steel cylinder. Their Electromagnetic Inspection Tool (EMIT®) was deployed to find areas of distress and corrosion.
- Diakont, based in Carlsbad, deployed two of their unique RODIS® robotic tools to use laser profilometry and Electromagnetic Acoustic Transducer (EMAT) technologies to assess thick steel pipe in the highest-pressure zones.
About a quarter of the planned work has been completed. The remainder is scheduled over the next 18 months.
Did you know the Water Authority uses robotic technology to inspect large-diameter pipelines? These robotic inspectors were designed by Diakont to help check within pipelines for areas that may need repairs. ? #cawater #innovation pic.twitter.com/4ywnyQ1Eb6

Outstanding record of innovation
For more than 20 years, the Water Authority has been developing innovative ways to maintain major water infrastructure worth billions of dollars.
Establishing unique partnerships with leading technology providers has ensured the best available tools are used in the most cost-effective ways. And, the strategic partnerships allow operations and maintenance teams to extend the lifespan of pipes as well as prevent failures.
In addition to extending pipeline lifespan, high-tech inspection tools are part of a proactive maintenance and repair process by reliably detecting pipeline anomalies and alerting staff to where potential problems may arise. As the tools travel through pipes, data is collected, downloaded and analyzed by staff. Then specific areas where repairs may be needed are identified. Without accurate data, staff would not be able to identify potential issues within the pipes, which could lead to disrupted service and inflated costs.
San Joaquin County has filed a lawsuit in Superior Court asking the state Department of Water Resources to abide by local drilling permit requirements to protect wildlife and water quality in accordance with California law. According to the county, DWR began geotechnical well drilling in San Joaquin and Sacramento counties in June to collect data the agency says it needs for a proposed Delta tunnel project. The controversial tunnel project would carry water diverted from the Sacramento River to the existing state and federal water pumps in the south Delta for export to points south.
The California almond has proved resilient under fire. During the late years of California’s most recent drought, from 2015 through 2016, the almond came under attack from a variety of sources, including news outlets such as Mother Jones, Forbes and the New Republic, labeling it a horticultural vampire. It was, they said, sucking California’s groundwater reserves dry, leaving behind brittle, drought-stricken trees and causing the dusty land in San Joaquin County to cave in. But the nut and the crop have not just survived, but thrived.
The core findings by Thomas W. Corringham and Daniel R. Cayan from the Scripps Institution of Oceanography, University of California San Diego, confirm when it comes to flood claims and damages, El Niño is a force to be reckoned with. Wading through 40 years of ocean temperatures confirmation of El Niño and La Niña events, the authors discovered flood damage claims can be ten times higher during an El Niño year. El Niño is a phenomena that occurs far from California in the middle of the Pacific Ocean. A change in wind direction can send warmer water from the Western Pacific to the usually cooler Eastern Pacific.

The San Diego County Farm Bureau’s longtime executive director Eric Larson retired recently after leading the Bureau for 23 years. He told the newspaper two weeks ago, “I decided 70 was a good age to exit. I will be working through the end of September. My replacement will begin July 22 giving us a good transition.” His replacement is Hannah Gbeh (pronounced bay). Gbeh is an environmental impact report preparer, organic farmer, environmental science teacher and researcher who has served for several years on the board of the San Diego County Farm Bureau. She is also a commissioner on the County’s Fish and Wildfire Advisory Commission and serves on the Jamul-Dulzura Community Planning Group.
At the July 26 San Diego Association of Governments board of directors meeting, city and county officials voted to advance the proposed draft methodology that it must send to the California Department of Housing and Community Development for approval. If approved, it could mean tens of thousands of additional housing units built in North County in the next decade. Called the Regional Housing Needs Assessment (RHNA), SANDAG’s version of it calls for the building for 171,685 new housing units during the 2021-2028 time period. Yet, not only do some board members see the number as high, some said they viewed the city-by-city allocation of housing requirements as flawed.
Earthquakes could have a major impact on San Diego’s water supply, even if they happen far away. That’s because San Diego’s water comes from hundreds of miles away, through threads of metal and concrete that connect us to distant rivers and reservoirs. Our biggest source of water is the Colorado River, which is diverted into Southern California from the Arizona border through a 242-mile water system that includes 92 miles of tunnels. On this week’s San Diego Explained, Voice of San Diego’s Ry Rivard and NBC 7’s Catherine Garcia lay out three worst-case scenarios that could affect San Diego’s water when an earthquake hits.
Opponents of the twin tunnels breathed a collective sigh of relief in April when Gov. Gavin Newsom put a formal end to the California WaterFix project, but that action also called for the assessment of a single-tunnel project in the Delta. The first major step in that direction took place last week when the Department of Water Resources (DWR) initiated a series of negotiations with public water agencies that participate in the State Water Project (SWP), to amend SWP contracts to accommodate the construction and operation of a single Delta tunnel, referred to as the Delta Conveyance Project. Of the 29 state contractors, five agencies that operate north of the Delta are expected to opt out of participation in the project.
