BDCP: Project Costs
“Users pay” for new conveyance facility and associated mitigationAll “beneficiaries pay” for habitat conservation and other state-wide benefits of the planAverage Cost for Southern Californians
~ $5 - 6/month per household
Improvements Capital O&M (Annual) Funding Source
Conveyance $14 billion $83 million Water Contractors
Eco-Restoration & Other Stressors $3.6 billion $46 million Fed/State/Water

Metropolitan is committed to meeting future additional water supply needs through local resources and conservation
Risks of Doing Nothing
Status QuoEcosystem declinePumping restrictions (supply reduced 30%)
Major Levee FailureUp to three-year disruption of water deliveries$40 billion estimated impact to California’s economy

Challenges Replacing SWP Supplies
SWP supplies are essential to alternative supply options
SWP provides baseline supplies that we conserve and recycleSWP provides valuable water quality benefits
Colorado River & groundwater blendingRecycling
Feasibility of alternative suppliesExample: desalination locations are limited
