Across Los Angeles County, regional agencies are investing in water infrastructure that strengthens today’s systems and prepares for tomorrow’s challenges. These efforts include expanding use of recycled water, stormwater capture, reservoir restoration, and upgrades to pipelines and treatment facilities—all aimed at boosting local supplies, protecting water quality, and boosting our climate resilience.
