San Diego is seeking input from the public on a new water plan introduced by Mayor Todd Gloria. Under the 2020 Urban Water Management Plan, the city would develop more than half of the city’s water locally by 2045.
We’re facing another very dry year, which follows one of the driest on record for Northern California and one of the hottest on record statewide.
The 2012-16 drought caused unprecedented stress to California’s ecosystems and pushed many native species to the brink of extinction, disrupting water management throughout the state. Are we ready to manage our freshwater ecosystems through another drought?
Every time someone turns on the tap in San Diego County, out flows the work of Peter MacLaggan.
MacLaggan was the point man in the construction of the Carlsbad desalination plant, a nearly $1 billion public-private partnership that since 2015 has supplied nearly 10 percent of the potable water consumed in the county.
Desalination relies on the virtually unlimited supply of water in the Pacific Ocean. It provides a safe, reliable source of local water in a region that for many years relied on supplies from hundreds of miles away and was subject to mechanical breakdowns, seasonal shortages and the whims of nature.
Since 1991, San Diego County ratepayers have conserved more than 1 million acre-feet of water, and per capita potable water use in the region decreased nearly 60 percent between fiscal years 1990 and 2019, according to the San Diego County Water Authority.
The findings are part of the Water Authority’s draft 2020 Urban Water Management Plan, which was released Monday for public review.
The report concludes that as a result of conservation and billions of dollars in infrastructure, San Diego should have sufficient water supplies through 2045.
“Thanks to decades of regional investments (and conservation) the draft plan shows that we don’t need to secure more regional supply sources for the foreseeable future,” Water Authority general manager Sandra Kerl said in a statement. “Instead we are focused on helping our member agencies develop local supplies, and looking for other ways we can continue to ensure supply reliability at a reasonable cost.”
As March begins to drag on with little precipitation in the forecast and few weeks left in California’s traditional wet season, we are in another dry year. This is California’s second dry year in a row since the 2012-2016 drought. Statistically, California has the most drought and flood years per average year than anywhere in the US. This statistical fact seems to becoming increasingly extreme, as predicted by many climate change models.
Forecasts based on U.S. Geological Survey data predict that the Klamath Basin will only fulfill about a third of what’s needed for agriculture. The Upper Klamath Lake is more than a foot lower than it was this time last year, which was also a drought year.
The Klamath County commissioners voted Tuesday to issue a county-level drought declaration. The board voted to request that Gov. Kate Brown’s office issue a state-level drought declaration, which would open up financial resources for water users.
The climate change cabal in Sacramento is ignoring some extremely low hanging fruit in their bid to protect us from ourselves.
The reason they don’t see it is simple. It doesn’t involve raising taxes, rewarding corporations or disruptor greenies they align with, nor does it destroy jobs.
The California Legislature needs to ban grass lawns for front yards as well as general commercial development for all new building projects.
Vice President Kamala Harris was right on point last year when she said that clean water is a fundamental human right. President Biden has put those words into action by signing an executive order establishing a White House council on environmental justice.
The San Diego County Water Authority’s draft 2020 Urban Water Management Plan was released for public review today. The plan highlights how regional investments in a “water portfolio approach” to supply management and a sustained emphasis on water-use efficiency mean that San Diego County will continue to have sufficient water supplies through the 2045 planning horizon — even during multiple dry years.
A 60-day public comment period on the draft plan ends May 6 and will include a public hearing on March 25. The Board of Directors is expected to consider adoption of the final plan during its regular meeting on May 27. The 2020 UWMP is due to the state by July 1, 2021.

“Thanks to decades of regional investments, the draft plan shows that we don’t need to secure more regional supply sources for the foreseeable future,” said Water Authority General Manager Sandra L. Kerl. “Instead, we are focused on helping our member agencies develop local supplies and looking for other ways we can continue to ensure supply reliability at a reasonable cost.”
The Water Authority started the current UWMP process in September 2018, coordinating closely with its 24 member agencies, most of which must submit their own plans to the state. Member agencies provided input into the draft plan as part of the Water Authority’s ongoing effort to align local and regional projections as closely as possible. The plan’s long-range demand forecast shows an increase in regional demands of less than 1% per year through 2045. This change in demand is consistent with the change forecasted by other large water suppliers, including the City of San Diego and the Metropolitan Water District of Southern California.
Multiple supply and demand projections factor into Urban Water Management Plans, which are mandated by the state to ensure sufficient supplies over 25 years. The plans are not used to set water rates; rates are set annually based on multiple financial factors at the time, not long-term projections about water supplies.
Urban Water Management Plans are dictated by statutory guidelines, Water Authority Board direction and an agreement with the San Diego Association of Governments to use its regional growth forecast. The plans also support state laws that link approval for large housing developments to water supply availability.
By law, the plans must be updated every five years. Per state guidelines, the Water Authority’s Urban Water Management Plan includes:
The demand forecast accounts for changes in socio-economic factors, such as the number of projected housing units, the mix of single-family and multi-family dwellings, and employment growth.
Conservation projections account for continued adoption of water-use efficiency measures, compliance with landscape water-use ordinances for new residential construction, and continued installations of sustainable landscapes at existing homes. Since 1991, San Diego County ratepayers have conserved more than 1 million acre-feet of water, and per capita potable water use in the region decreased nearly 60% between fiscal years 1990 and 2019.
The draft 2020 Urban Water Management Plan shows how regional investments by the San Diego County Water Authority in a “water portfolio approach” mean that San Diego County will continue to have sufficient supplies, including locally-controlled drinking water from the Claude “Bud” Lewis Carlsbad Desalination Plant, the largest, most technologically-advanced and energy efficient desalination plant in the nation.

The draft 2020 UWMP also highlights the value of the Water Authority’s long-term strategy to invest in highly reliable and locally controlled supplies from the Claude “Bud” Lewis Carlsbad Desalination Plant and the nation’s largest conservation-and-transfer agreement, which provides high-priority, low-cost water from the Colorado River.
In addition to the UWMP, the Water Authority also regularly updates its Regional Water Facilities Optimization and Master Plan, which focuses on the infrastructure necessary to meet projected long-term demands, and its Long-Range Financing Plan. Those documents work together to ensure the right mix of supplies and facilities to meet the region’s needs at an affordable cost.
