Effective July 1, the Water Authority is reducing water supply deliveries to its 24 member agencies by 8 percent. The Water Authority is taking this action as a response to reduced water supplies caused by regulatory restrictions on water deliveries from Northern California, lingering drought, and a 13 percent cutback from the Water Authority's largest water supplier, the Metropolitan Water District of Southern California. In April 2009, to prepare for these cutbacks, the Water Authority declared a Level 2 "Drought Alert," enabling member agencies to implement local mandatory water restrictions. Restrictions will vary by member agency. To find out the restrictions in your area, please visit www.sdcwa.org/manage/droughtordinance_agencies.phtml

5. Three Challenges to Our Water Supply
1. Regulatory
Pumping restrictions are sharply limiting
imported water from Northern California
2. Drought
Last three years in California
8 of last 10 on the Colorado River
3. Low storage
Major reservoirs have been drawn down
to low levels

14. The Impact on Rates
$ $$ $$$ $$$$
Colorado River State Water Spot Water Loss of Sales
Water Project Transfers (Shortage)
<2003 2003-2007 2008> 2009-10?
Supply challenges make securing water more expensive
Shift to more-expensive supplies is driving up the cost of water
from MWD, the Water Authority’s largest supplier
Water Authority passes increased costs to member agencies
18.1 % rate increase to take effect Sept. 1, 2009
Member (retail) agencies pass costs to ratepayers
