Reduce imported water percentage

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.

Reduce per capita water consumption

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.

Implement Pure Water program on schedule

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.

Decrease percentage of days beaches are closed due to water quality

The City of San Diego Public Utilities Department, with Transportation & Storm Water Department and the San Diego County Department of Public Health, are focused on eliminating sewage spills, stormwater contamination, and beach closures. This is important for continuous public safety and recreational enjoyment at San Diego’s beaches. Beach closures are issued whenever a sewage spill impacts a beach and the public should avoid contaminated waters.

Sewage spill events are diligently investigated and the public is notified through sdbeachinfo.com, Twitter, Facebook, email, press release, phone hotline, and beach signage. Sampling and analyses are conducted to ensure the water is safe prior to lifting closures.

Reduce greenhouse gas emissions citywide

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.

* During Fiscal Year 2016, new departmental tactical plans and key performance indicators were developed. This is a new indicator, so historical information for this metric is unavailable.

Extend the useful life of Miramar landfill

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:
  • Vertical expansions
  • Using a "pancake" method to increase compaction
  • Alternating tarps with dirt as a daily cover
  • Leasing a larger, heavier class of trash compactor
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.
