RELIABLE WATER SUPPLIES
FOR ABOUT $5 PER MONTH
The Bay Delta Conservation Plan (BDCP) seeks to protect the reliability of California’s two largest water projects that tap a major source of supply – the Sierra Nevada mountains - by improving how water moves through the Sacramento-San Joaquin River Delta (Delta) . The price of reliable water supplies from BDCP implementation is projected at about $5 a month for urban water users. Ratepayers from the Bay Area to San Diego who rely on water from the Sierra Nevada mountains, by way of the Delta, will pay for the water delivery improvements – an estimated $14.5 billion over the project’s 50-year implementation period.
As one part of the state’s overall water plan, the BDCP’s proposed water delivery improvements seek to stabilize Delta water supplies, respond to climate change, and protect against natural disasters. For farming communities that depend on imported Delta supplies in the San Joaquin Valley, the potential for new local supplies, particularly groundwater, is limited. For urban communities facing population growth, climate change and other pressures, BDCP does not eliminate the need for investment in conservation and local water supplies such as recycling, groundwater cleanup and desalination. The BDCP is expected to provide, on average, supplies comparable to those delivered over the last 20 years at the cost of about $800-900 per acre-foot of water* for urban areas. (One acre-foot is about as much water as two California households use each year).
*Urban water treatment and transportation is factored into cost range.
