Budget & Finance

To keep our vast water delivery system running smoothly and invest to meet Southern California’s water demands for generations to come, Metropolitan maintains an annual operating budget of nearly $2 billion. We make forward-thinking investments  in supplies, in storage, in conservation and in treatment and we responsibly maintain our existing infrastructure. These strategically important programs together provide Metropolitan operational flexibility to store water when it is available and provide it to our communities in dry years. Our water rates are established to recover the cost of providing this water service in an open and transparent public process as part of the biennial budget.

Our adopted biennial budget for fiscal years 2022/23 and 2023/24 as well as the adopted rates and charges for the calendar years 2023 and 2024 documents can be reviewed here.

Metropolitan’s strategic investments in a diverse portfolio of water supplies and storage have helped ensure the region has a reliable water supply amid California’s highly variable annual precipitation and snowpack. 

Investing in Southern California  

Our most recent $3.9 billion biennial budget (Fiscal Year 2020/21 and FY 2021/22), includes capital spending about $500 million, largely to rehabilitate existing facilities so they are well-maintained and seismically-sound. More than half of these projects are funded from operating revenues, rather than debt financed.

Among some of Metropolitan’s largest strategic investments in recent years:

Regional Recycled Water Program

In partnership with the Los Angeles County Sanitation Districts, a demonstration facility in Carson has been built to test new treatment methods to purify wastewater. The facility could pave the way for one of the nation’s largest water recycling facilities.

Conservation and local resources icon

Conservation & Local Resources

Metropolitan has invested $1.5 billion in water conservation, recycled water and groundwater recovery since 1990.

Storage icon


Metropolitan has developed more than 5.5 million acre-feet of storage capacity – a 13 times increase in capacity since 1990.
