For more than 15 years, a pair of sewage treatment plants in eastern Tijuana have presented an opportunity – and a challenge.
The plants, Arturo Herrera and La Morita, raised hopes for a major wastewater reuse effort in the city – for irrigation, construction and industrial use. U.S. and Mexican authorities celebrated their opening, saying the effort would benefit both sides of the border.
The City of San Diego is repairing a major leak in a 36-inch water main off Black Mountain in Rancho Peñasquitos.
City workers had to bring in heavy equipment to dig down and locate the break in the water transmission line of Carmel Valley Road.
Artificial intelligence technology is guzzling water and energy in California and around the globe, yet most tech companies have not been forthcoming about the actual environmental costs of their applications, my colleague Melody Petersen reports.
That’s a huge problem, as their energy and water consumption will undoubtedly strain supplies and drive up demand for climate-warming oil, gas and coal — all while leaving users in the dark about their true contributions.
An unusually cold weather system from the Gulf of Alaska interrupted summer along the West Coast over the weekend, bringing snow to mountains in California and the Pacific Northwest and prompting the closure of part of a highway that runs through a national park.

Guest speaker Dr. Maria-Elana Giner, P.E., shared her career journey that led her to be appointed by President Joe Biden as Commissioner of the United States International Boundary Commission in 2021. Giner is the second woman, and first Latina, to hold this position.

Gov. Gavin Newsom is making moves to keep control of California’s water — and protect the state’s endangered species from a potential second Trump administration.
With federal and state officials in the midst of renegotiating how they manage a 400-mile system of reservoirs, pumps and canals that moves water out of the San Joaquin-Sacramento River Delta to deliver it to taps and farms across the state, California water officials are taking steps to adopt guidelines from the state’s own wildlife officials rather than federal ones.
For nine out of the last 13 years, California was in a state of drought. The five-year drought from 2012 and 2016 is one of the top five most severe droughts California experienced in the last 120 years. Many wells went dry during this period; farmers fallowed land; some rural communities had no running water; and trees died in mass in the Sierra.
Against this backdrop, Governor Jerry Brown issued a record number of executive orders and emergency proclamations regarding drought and water conservation during this period.
Shortly after the California Coastal Commission’s stunning rejection of Poseidon Water’s $1.4 billion ocean desalination plant proposal for Huntington Beach, Poseidon’s long—time VP of development, Scott Maloni, quipped on Facebook about the “unjust decision,” which put an end to big ocean desal in California for the foreseeable future.
“The silver lining,” he wrote, “San Diego has a water unicorn. The Carlsbad Desalination Plant is a one-of-a-kind treasure that will never be replicated again in the state of California.”
While the process of paving over underground repairs and refilling the feeder main line brought a collective sigh of relief in Calgary, critical water quality tests loomed as workers focused on the finish line in the dwindling days of June.
The more than three-week ordeal of repairing the nearly 50-year-old, 11 kilometre-long, two-metre diameter feeder main was a significant challenge for Calgary’s Water Services Director, Nancy Mackay, her team, and other municipal departments, not to mention the city’s 1.6 million residents.
Mexico is facing a growing water shortage, leading to unpredictable, often lengthy water shut-offs in Tijuana.
Meanwhile, millions of gallons of wastewater are dumped from Tijuana into the Pacific Ocean each day. In the future, that water could be recycled, putting a significant dent in the country’s water supply issue.
