Securing Our Water Future

Climate Adaptation
Master Plan
for Water

Climate change is here and it’s impacting all of our water resources.

Metropolitan’s responsibility as Southern California’s water importer and provider is to look decades ahead to ensure supplies remain reliable. That’s why we are developing the Climate Adaptation Master Plan for Water or CAMP4W – to adapt the way we deliver and store water for the realities of a changing climate. Watch an introductory video that outlines our commitment to securing our water future for generations to come.

The High Desert Water Bank:
A Collaborative Effort

An exciting new project has emerged from the arid landscape in the sun-soaked desert of Lancaster — the High Desert Water Bank.

A collaborative effort between Metropolitan and the Antelope Valley-East Kern Water Agency, the first stage of the new groundwater storage project that significantly improves the resilience for Southern California's water supply is up and running.

Conservation Rebates

Drought Relief Grant:
Funds to Boost Rebates

Being prepared for a future of climate extremes requires partnership at all agency levels to strengthen our water resiliency and commitment to save water.

The California Department of Water Resources recently awarded Metropolitan $38 million from its Urban Community Drought Relief Program to support commercial turf replacement rebates and other conservation programs.

Project Labor Agreement

The Project Labor Agreement: A Year in Review

Metropolitan joined Building and Construction trades to sign an agreement in October 2022 with a focus on community, equity and outreach to underrepresented people focused on careers in construction. The Project Labor Agreement includes 34 Metropolitan projects aimed at making Southern California water supplies more resilient to a changing climate. 

Let’s take a look at the impact of the PLA one year out.

Take a Tour___

From Source
To Tap.

Follow the extraordinary journey your water must take before you use it, from sources high in the Rockies and the Sierra Nevada, through critical purification processes, to homes and businesses across Southern California.

Workforce Investment___

the Way.

Supplying 40 percent of California’s water resources requires a workforce that is as agile and efficient as the water delivery systems we develop and operate. Succession planning, diversity, and asset retention are vital areas of focus that are key to the success of our organization.

An animation about the Metropolitan's workforce. Their workforce includes 1756 employees, of which 28% were women and 55% were people of color as of 2019. The workforce is composed of 35% professionals, 24% skilled craft workers, 17% office and administration, and 13% technicians. The average years of service at Metropolitan is 14 years, with 43% of staff having over 14 years of service.

Strategic Priorities___

Pathway to
the Future.

With a focus on areas of change and opportunity, Metropolitan - in an inclusive process - identified five strategic priorities that form an action-based framework for our approach to transformation. They support long-term stability and are attuned to the challenges of climate change, responsibilities to the public and our workforce, the importance of a sound business plan and continued collaboration with the communities we serve.

Learning to Conserve___


Supporting Sustainability Through Conservation.

Southern Californians get it. They know our water resources are not limitless. They’ve learned to conserve. And they know they can do more. That is where Metropolitan comes in. We offer water-saving tips, classes, and rebates for water-saving devices and sustainable landscaping. We are your partner as you learn how to make conservation a way of life.
