Fixing California’s Aging Water Distribution System is Critical to Protect San Diego's Water Reliability.
The Problem: The water distribution system that delivers water to San Diego homes and businesses is outdated and at risk of failing.
San Diego benefits from California’s main water distribution system, which brings water long distances from the Sierra Nevada Mountains through a system of aging levees, canals and pipes to our region. On average, 29% of San Diego’s water supply flows through the state’s main water distribution system, with as much as 49% of our local water supply in peak years.
But key portions of the system are outdated and crumbling. Experts warn that the system could collapse in an earthquake or natural disaster, cutting off water supplies to our region for more than a year. This water delivery system also needs to be modernized to better prepare for climate change and the resulting extreme droughts, severe floods, and increasing salinity in the Delta caused by rising sea levels.
The Solution: Support Governor Newsom’s single pipeline conveyance through the Delta.
The project would fortify water supplies delivered to San Diego. It would:
Protect water security for two-thirds of the state. Without action, water supplies through our main distribution infrastructure will continue to decrease.
Improve the safety and reliability of our water system by fixing aging infrastructure using the most innovative technologies and engineering practices.
Protect water supplies from earthquakes, floods and natural disasters by delivering them through a modern water pipeline, rather than solely through today’s deteriorating levee system.
Prepare For The Impacts
Of Climate Change
Prepare for the impacts of climate change by improving our ability to move and store water, recharge groundwater aquifers, and protect against salinity caused by sea-level rise.
and Natural Water Flows
Restore habitats and more natural water flows above ground in rivers and streams in order to reduce impacts on endangered fish and other wildlife.
