DESCRIPTION
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
