The Reality of Water in Northern San Diego County

Northern San Diego County has prepared for both the current and future drought situations. 
The region has been hard at work for the past decade diversifying its water supply in order to reduce 
reliance on imported supplies.  Water agencies have planned for Northern San Diego County’s needs through times of drought, economic expansion, and population growth.

Where do our current water supplies come from?

While each individual local water agency in the county has a slighty different water supply portfolio, in 
general, the supplies in the region for Fiscal Year 2016 will come from:

64% from the Colorado River via Metropolitan Water District, water transfer agreement with 
the Imperial Irrigation District, and lining of the Coachella and All American Canals.

19% from the State Water Project comes from Northern California, also known as the Bay-Delta

17% from local supplies

improve water use efficiency at residential properties. Funding is limited and available on a first-come, first-served basis.

Carlsbad Seawater Desalination

Construction is more than 90% complete on the Carlsbad Desalination Project, which includes the nation’s largest, most 
technologically advanced and energy-efficient seawater desalination plant, a 10-mile long pipeline and 
improvements to Water Authority facilites for distributing desalinated water throughout San Diego County.

The Carlsbad Desalination conveyance pipeline, a 54-inch water delivery pipeline that will travel eastward from the 
seawater desalination plant through Carlsbad, Vista and San Marcos to the San Diego County Water 
Authority’s Second Aqueduct connection facility in San Marcos.

The $1 billion project is expected to produce drinking water for the San Diego region in fall 2015, providing a major new 
drought-proof water supply that will meet about 7 to 10 percent of the county’s water demands. To keep the public 
informed about the progress of construction, regular construction updates on the timing and potential 
detours and closures will be posted on the project website at www.carlsbad-desal.com.
With San Marcos leading the way in water conservation in Northern San Diego 
now is the perfect time buy!
