As water agencies across California grapple with the increasingly extreme effects of climate change, they’re also facing another problem: the incoming “silver tsunami.”
That’s the phrase coined by the industry to illustrate the fact that much of the workforce — largely baby boomers — that keeps our water flowing and safe are getting ready to retire.
Nationwide, about a third of the nation’s water workforce is eligible for retirement within the next decade, “the majority being workers with trade jobs in mission critical positions,” the Environmental Protection Agency wrote in a 2024 report.
Climate resilience needs a workforce
To deal with how pollution in our atmosphere is driving longer, hotter droughts, as well as increasingly intense rain when it does come, water agencies across Southern California are working to boost aging infrastructure and invest in more diverse water supplies, such as recycled water.
The lack of people to staff those changes is a problem for pretty much every water agency, urban and rural.
L.A. is the second-largest city in the nation and is spending billions on water recycling and stormwater capture, for example, but it has been struggling to fill needed positions at its four wastewater treatment plants.
The city plans to treat nearly all of the Hyperion wastewater facility’s water to drinkable standards in the coming decades. To support that massive expansion, Hi-Sang Kim, the operations director at Hyperion, told LAist in 2022 the facility will need to boost its workforce by at least 30%.
For less urban water agencies, the challenge is even greater. The Eastern Municipal Water District serves close to 1 million people (and growing), as well as agricultural customers in western Riverside County and northern San Diego County.
They estimate as much as half of their workforce could retire within five years.
"We are in dire need of technical skill sets."
“Not only are we investing in new infrastructure, but we have aging infrastructure, so we are in dire need of technical skill sets to operate, maintain everything from treatment plants to pipelines, to pump stations,” said Joe Mouawad, the water district's general manager.
Jobs in the water industry — potable water and wastewater treatment operators, engineers, managers, skilled maintenance, public relations and more — are well paid and secure, Mouawad said, but it’s hard to fill the needed positions.
“We are finding it more challenging to backfill retirees,” he said. “It's not so much a lack of interest — I think it's a lack of awareness.”

Building a pipeline for water jobs
Those job gaps are why Eastern Municipal has become a leader in building the water workforce pipeline. For decades, the water district partnered with local schools to provide education about water conservation and what they do. But over the last decade, as the retirement forecast grew more dire, the agency has shifted to prioritize skills-based programming and partnerships with local high schools.
In 2013, they launched the Youth Ecology Corps program, for young adults between 18 and 24. Many who went through the program and paid internships are now full-time employees, said Calen Daniels, a spokesperson for the agency, who himself went through the program.
In recent years, the water agency has focused on younger potential future employees through a variety of Career and Technical Education programs at local high schools, including in automotive tech, engineering, agriculture, construction and information systems, said Erin Guerrero, Eastern Municipal’s public affairs manager overseeing its education programs.
“We're starting earlier and getting these kids real world experience,” Guerrero said.
Michelle Serrano teaches a two-year pre-apprenticeship Environmental Water Resources program at West Valley High School in Hemet. Students leave the program equipped to take the state-level certification exam for a job as a water treatment operator or water distribution operator once they turn 18.
Already more than 200 students have gone through the program since it launched last year. While local community colleges have similar Career and Technical Education programs, this is the first program of its kind targeting high schoolers in the region. Eastern Municipal hopes to expand to other area schools as well.
“Once the kids get out of the program, they're set if this is the direction they want to go,” Serrano said. “We have these students set for a job or a career for the rest of their life.”
"Once the kids get out of the program, they're set if this is the direction they want to go."
She said the program is a gamechanger for students who don’t see themselves going to college or who are unsure of their future career path.
“We really are pushing hard for college, and that's a good push,” Serrano said. “However, we have kids who don't see themselves going to college. It's opening up an amazing path for students who otherwise may not see a job direction.”
They’re not only finding a stable career path, she said, but fulfilling roles necessary to our society, Mouawad said.
“It's working for us,” he said, “and we want to see this serve as a model for the rest of the industry.”
