New Water Year

New Water Year
Same Commitment to Reliability

Securing the water we need for Southern California is a monumental responsibility – one that takes careful planning and strategic decisions. Tracking the rain and snowmelt over the water year (Oct. 1 to Sept. 30) helps us in this effort.

We kicked off the 2025 water year on Oct. 1 in great shape, with enough water in storage to support the region when drought conditions return.

Future of Reuse

The Future of Regional Water Reuse:
Pure Water Southern California

Now is an exciting time for recycled water programs across California. In December 2023, after nearly a decade of careful planning and review, with input from scientists and public health experts, the state released new direct potable reuse regulations that now permit the purification of recycled water for direct use in our drinking water systems. This has big implications for our Pure Water Southern California Program.

Tree Rebate

New Rebate for Trees:
Supporting Our Turf Replacement Program

Trees are nature’s superheroes. Metropolitan’s new tree rebate recognizes the invaluable role they play in maintaining healthy and resilient urban environments. Trees act as natural air purifiers, and their leaves and branches provide cool refuge with much-needed shade. That’s why Southern California residents can now receive a $100 rebate per tree for up to five trees planted while they replace thirsty grass with a more sustainable and water-efficient landscape.

It’s fitting that concentric circles are the cover design motif for Metropolitan’s latest publication, Leadership Today, Water Tomorrow. Concentric circles have a common center and run parallel. Metropolitan’s common core is providing reliable and safe water to Southern California in an environmentally and economically responsible way. The way we do that has many layers.

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 1782 employees, of which 28% were women and 58% were people of color as of 2023. The workforce is composed of 35% professionals, 25% skilled craft workers, 18% office and administration, and 12% technicians.
