Los Angeles County contains a complex network of over 200 community water systems, each managed by a separate set of decision-makers and policies. The 2020 Los Angeles County Water System Governance Map supports residents to understand who governs their water and become active participants in holding their water system leaders accountable to provide clean and affordable drinking water.
