Budget & Finance

Metropolitan maintains an annual operating budget of nearly $2 billion, ensuring that our vast water system runs smoothly and that we will meet Southern California’s water demands for generations to come.

We make forward-thinking investments in supplies, storage, conservation, and treatment, and we responsibly maintain our existing infrastructure. Together, these strategically important programs provide Metropolitan with the operational flexibility to store water when it is available and deliver it to our communities in dry years. Our water rates, which recover the cost of providing reliable water service to our member agencies, are established in an open and transparent public process as part of the biennial budget.


Our Adopted Biennial Budget

At its April 9 monthly meeting, our board approved the proposed biennial budget for 2024/25, which strategically balances necessary rate increases with cost containment measures, including reducing departmental expenditures.

The budget and rates approved evolved through months of transparent deliberations, including input from member agencies, interested parties and the public. Metropolitan’s board began discussing the budget in February and has held four public workshops to consider Metropolitan’s expenditures and revenues.

Investing in Southern California  

The adopted budget for fiscal years 2022/23 and 2023/24 appropriates $4.4 billion, including $600 million in capital investments to address aging infrastructure, respond to drought, and comply with regulatory requirements. 

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

*On Nov. 14, 2023, at the FAIRP meeting, staff presented to the Board the status of the 2014 Purchase Order, which will end on Dec. 31, 2024. The adopted FY 2024/25 and FY 2025/26 Biennial Budget does not assume that the purchase order contracts will be renewed. As a result, the Tier 2 rate is not included in the proposed rates and charges for CYs 2025 and 2026; there is only a single supply rate. Metropolitan will revisit the purchase order commitments and similar structures as needed during the business model review through the CAMP4W process.


  • Tier 1 Supply Rate – recovers the cost of developing and maintaining a reliable water supply
  • Tier 2 Supply Rate – set at Metropolitan's cost of purchasing water transfers north of the Delta, this rate tier encourages the maintenance of existing local supplies and the development of cost-effective local supply resources and conservation
  • System Access Rate – recovers costs associated with the interconnected regional delivery network necessary to deliver water to meet member agencies' average annual demands. Included are the costs of conveyance and distribution facilities
  • System Power Rate – recovers Metropolitan's power costs for pumping supplies to Southern California
  • Treatment Surcharge – recovers the costs of treating imported water
  • Readiness-to-Serve Charge - a fixed charge that recovers the costs of providing emergency service and available capacity to meet outages, emergencies and hydrologic variability
  • Capacity Charge – recovers the cost of providing peaking capacity within the distribution system which Metropolitan owns or has the right to use
