Water leaders in
For example, the
California Legislature in late 2009 passed a new “policy of the State of
regional supplies, conservation, and water use efficiency.” According to this policy, “each region…shall improve its regional self-reliance for water through investment in water use efficiency, water recycling,

supply reliability over the next 25 years in

efforts to manage water supply and demand conditions and to stabilize MWD’s traditional
imports from the
• A cost-effective “supply buffer” will help protect the region from possible shortages caused by conditions that exceed the core resources strategy, starting with increased conservation and water-use efficiency on a region-wide basis.
- Foundational actions guide the region in determining alternative supply options for long-range planning.
If future changed conditions – such as climate change or the availability of resources exceed what is covered by MWD’s core resources and supply buffer – these alternatives would provide a greater contribution to water reliability than MWD’s imported water sources or any other single supply.
