The Pure Water Program will provide up to one-third of the local water supply by 2035, helping to reduce the City’s reliance on imported water. Other water supply diversification efforts include desalinated and recycled water use and development of groundwater resources.
The Public Utilities Department has typically provided potable water from two sources. About 10 to 15 percent of water on average comes from local sources, especially reservoirs. The remaining 85 to 90 percent is purchased from the San Diego County Water Authority. The majority of purchased water is raw imported water from the Colorado River and the California State Water Project.
Reducing the number of gallons of water consumed per capita daily (GPCD) is a requirement of the Conservation Act, passed by the California Senate in 2009. The target reduction is 20 percent by 2020, using a 10-year base period, which is 142 gallons in 2010 for San Diego. Reductions in GPCD encourage sustainable and efficient water use and allow water supplies to last longer.
Pure Water San Diego is the City’s phased, multi-year program to use proven water purification technology to produce a safe, sustainable and high-quality water supply for San Diego through potable reuse. The program, divided into three development phases, aims to produce 83 million gallons of purified water daily by 2035. It is environmentally friendly and will make San Diego more water-independent and resilient against drought, climate change, and natural disasters while reducing the Point Loma Wastewater Treatment Plant’s ocean discharges.

The City adopted the Climate Action Plan (CAP) in 2015. The CAP established a 2010 citywide greenhouse gas (GHG) emissions baseline of 12.9 million metric tons. The CAP outlines the actions the City will take to reduce emissions both throughout the community and from City sources.
Goals and actions focus on increasing the use of renewable energy, energy and water efficiency, mobility improvements, zero waste, and climate resilience measures such as urban tree increases.
The City has been actively pursuing measures to extend the life of the Miramar landfill by increasing capacity of the permitted landfill space and by diverting materials through reduction, reuse, and recycling programs.
The remaining capacity of the landfill has increased over the previous five years through:
Additional efforts to improve recycling and implement the City’s Zero Waste Plan have also pushed anticipated closure of the landfill from 2021 to 2030.
