Career Pivot- Late 20s with service background looking to enter California water sector/utilities. Where to start ?

I am a woman in my late 20s (5 years post-college in an unrelated field in the arts) looking to transition into a career in the water sector here in California.
Some of My Background:
AmeriCorps: Team Leader for trail building, firebreaks, youth development, and camp maintenance
Peace Corps: University program management and design, volunteerism, community development, and women's livelihood projects.

Ive also worked at an environmental construction company in their nursery section growing native plants, and done non-profit community development work and social services. Also have done social media and community outreach as well (but I don’t want to utilize my arts background anymore doing social media etc big career pivot)

What I’m Looking For:
I love systems, math, logistics, and project management. I want a practical, AI-resistant utility career that truly matters. I highly respect the trades (most of my family is in them) and I know I need to learn the groundwork before I can eventually move into supervisor or liaison roles. I also love working with people, problem solving, and mentorship.

My Plan & Questions:
My research points toward getting a California D1 (Water Distribution) certification and taking the Sacramento State Office of Water Programs online courses.
Is starting with a D1 and Sac State courses the fastest way to get my foot in the door for an entry-level role?
Given my heavy project management and leadership background, what specific entry-level job titles should I target to get that hands-on experience?
Any tips for a woman breaking into the operational side of California utilities?
What should I be applying for in this journey?
