On the beach in Southern California, it’s easy to look at the Pacific Ocean and wonder what would happen if we could drink it. It’s already happening in some places, and others from Arizona to the California coast want to expand desalination. If big cities there use more of the ocean and less of the Colorado River, would that leave more water for the southwest? Part 4 of a 10-part series.
The Imperial Valley has been a senior water rights holder on the Colorado River for more than 100 years. Since our founding, our farmers, and the local Imperial Irrigation District, have long viewed our water seniority as both a property right and a responsibility. As much as we believe in upholding the rule of law, we are equally committed to being responsible water users and doing our part to keep the river healthy enough to meet the needs of all seven states. Imperial Valley farms and regional water agencies have implemented a host of conservation measures throughout the past twenty years, allowing farmers to conserve large amounts of water while still producing the food our country depends on.
Middle and high school students from San Diego and Imperial counties showcased their creativity and innovation in water technology at the Greater San Diego Science and Engineering Fair.
Winning students at the March event presented multi-faceted water technology designed for use in agriculture, water conservation, safety and treatment, creating solutions to some of the San Diego region’s most pressing water issues.
For decades, the San Diego County Water Authority has partnered with the Greater San Diego Science and Engineering Fair to inspire students to pursue water industry careers and experiment with sustainable water designs.
During state Assembly testimony on Tuesday, May 2, San Diego County Water Authority General Manager Sandra L. Kerl highlighted the steps taken by the Water Authority and partner water agencies across California to support the Colorado River in the era of climate change.

Kyle Tianshi and Sarah Gao tied for first place in the senior division for their development of water purifying technologies. Tianshi, an eleventh grader at The Cambridge School, focused on water pollutant identification through light scattering. Tianshi said the project used fluorescent emissions and lasers to detect microplastics in drinking water.
Gao’s work with wastewater treatment experimented with plant seeds as flocculants for water purification. A Canyon Crest Academy sophomore, Gao was also named an ISEF finalist for her work and will compete in the Regeneron International Science and Engineering Fair in Dallas, Texas in May.
Srija Sengupta from Westview High School took home the second-place senior award for her project, “Good on Land and Bad in Water: Effects of Fertilizer-Rich Runoff on Algal Growth.” Sengupta’s research tested the effects of fertilizer runoff in Dixon Lake and the subsequent impact on marine life, finding that phosphorous-rich fertilizers contributed the most to algae growth.
In the junior division, Ryan Richardson was awarded first place for his automatic faucet invention. When tested, Richardson’s faucet was found to save more than 50% of water in a household of four, prioritizing water conservation. He is already pursuing a patent for his invention.
From Saint Gregory the Great Catholic School, seventh graders Joaquin Revilla Harker and Tyler Rowe earned the second-place junior division title. Harker and Rowe’s research tested the growth capabilities of different water on grass, finding that gray water was the most suitable for growth, which can help conserve drinking water.
Caleb Raagas, who is also a seventh grader at Saint Gregory the Great Catholic School, was awarded the junior division’s third place award for his research on the effects of salinity levels on the production of hydroelectricity.
“This year’s winners all developed projects that address or could help solve a critical issue related to water, such as water quality, water supply management, and water purification,” said Sami Sweis, Engineer P.E. at the Water Authority. “Our industry needs bright young people like these students to use cutting-edge technology and innovation to help maintain safe and reliable water supplies for generations to come.”
There are more than 2,800 professionals in the water and wastewater industry in San Diego County, who work hard to provide safe and reliable water supplies to the region. The Water Authority’s continued partnerships with the community work to guarantee a future of opportunity for students interested in being a part of this industry.
While Arizona received more rain and snow in recent months, a wet winter will not save the state from the decades-long mega-drought that is gripping the region. Water officials have worked on finding unique solutions, including desalination.
Should two rural North County communities be allowed to purchase cheaper water from outside of the San Diego region in a desperate attempt to save farming — even if it could mean slightly higher bills for other ratepayers?
Each year on April 22, one billion people across the globe take action to promote conservation and sustainability. Earth Day can drive a year — and even a lifetime — of energy, enthusiasm, and commitment to protect our planet.
This year’s Earth Day theme — “Invest in Our Planet” — aligns perfectly with what the San Diego County Water Authority and its 24 member agencies have done for decades. It points to the necessity of dedicating time and resources to ensuring a sustainable water supply for our community. And it speaks to the thoughtful investments we make in infrastructure and innovation that keep the water flowing while being mindful of the environment.
Investing in our planet can take many forms, and the challenges we face differ from community to community. One investment I encourage San Diegans to think about this Earth Day is landscape transformation. This is important because the biggest users of water at homes are our landscapes — perhaps as much as 70% of our water use, depending on where we live.
The San Diego County Water Authority said a new federal report that forecasts significant increases in reservoir levels along the Colorado River is “welcome news” for San Diego’s water supply.
The report released Thursday by the U.S. Bureau of Reclamation forecasts that a near-record snowpack will raise Lake Mead at Hoover Dam by over 20 feet and Lake Powell farther north by 50 feet.
About two-thirds of San Diego County’s supplies are conserved Colorado River water.
Dan Denham, the Water Authority’s deputy general manager, said the federal report “is definitely welcome news and will buy us time to make crucial decisions.”
A federal report released April 20 says near-record snowpack in the Colorado River Basin could raise the elevation of Lake Mead by more than 20 feet by the end of the year, providing a critical opportunity for water agencies to improve long-term management of the river.
The U.S. Bureau of Reclamation’s report shows vastly improved hydrological conditions are also expected to raise the water level in Lake Powell by more than 50 feet. California relies heavily on lakes Powell and Mead for water, as do Arizona and Nevada.
Despite the good news this year, the ongoing trend toward a hotter and drier climate means long-term solutions remain critical. About two-thirds of San Diego County’s supplies are conserved Colorado River water.
