Asbestos in Old Water Pipes Raises Concern for Carlsbad Condo Project

Carlsbad’s Planning Commission has approved 12 condominiums for a Jefferson Street lot occupied by one single-family home, despite concerns about hooking up to the city’s old water pipes made with asbestos.

Asbestos, a known carcinogen, was widely used to reinforce concrete water and sewer pipes from the 1930s through the 1970s, including the pipes in Carlsbad’s downtown water supply system. The pipes generally are considered safe unless broken or damaged to release the asbestos.

Weak and Exposed: U.S. Water Utilities a Chinese Hacker Target

Rural America is a long way from Taiwan. But cyber power is no respecter of geography. Should China make good on its repeated threats to reunify the island by force, the utilities that provide water and power to small towns all over the United States may find themselves on the digital front lines of a 21st century superpower war.

Hackers linked to China have accessed the IT networks of hundreds of small and medium-sized U.S. water systems and other utilities with a view to sabotaging American water and power supplies in the event of a conflict, CBS reported this week, detailing a threat that U.S. officials warned of two and a half years ago.

Rain Barrels Help San Diego County Residents Capture Stormwater

San Diego County residents are turning to rain barrels to make the most of Tuesday’s rainfall, with environmental advocates saying even small amounts of precipitation can provide months of garden irrigation.

A 50-gallon rain barrel can capture significant amounts of water during San Diego’s infrequent rain events, according to Jessica Toth, executive director of the Solana Center for Environmental Innovation.

California’s Solar Canals Make Clean Power and Save Water at the Same Time

In California’s Central Valley, an ambitious project is transforming the way we think about renewable energy by installing solar panels across canals instead of on land. The $20 million pilot, called Project Nexus, has turned sections of the Turlock Irrigation District (TID) canal network into clean electricity generators.

Completed in August 2025, this 1.6-megawatt installation is the first of its kind in the state and only the second in the United States. The idea behind this project is simple but powerful. Instead of covering farmland or natural habitats with solar farms, why not use the open space above canals to produce electricity?

Here’s How Much Your Otay Water Bill Is Going up Next Year

Southeastern San Diego County residents can expect even pricier water bills due to higher sewer rates that their water agency approved earlier this month.

Otay Water District board members unanimously approved gradually increasing sewer rates over a five-year period. Next year’s hike takes effect in January and will raise the cost of sewer service by about 4%, though increases in subsequent years could reach nearly 10%.

San Diego Thinks It’s Found a Way to Fix Its Crumbling Infrastructure Faster

San Diego is stepping up its efforts to tackle billions in overdue infrastructure projects by shifting to a model where contractors help design projects, instead of just building ones already designed by city engineers.

Officials expect the new model, which the City Council approved last week, to reduce cost overruns, improve quality, boost transparency and help the city tackle its massive infrastructure backlog more quickly.

UN Agency Says C02 Levels Hit Record High Last Year, Causing More Extreme Weather

Heat-trapping carbon dioxide levels in the atmosphere jumped by the highest amount on record last year, soaring to a level not seen in human civilization and “turbo-charging” the Earth’s climate and causing more extreme weather, the United Nations weather agency said Wednesday.

The World Meteorological Organization said in its latest bulletin on greenhouse gases, an annual study released ahead of the U.N.’s annual climate conference, that C02 growth rates have now tripled since the 1960s, and reached levels not seen in at least 800,000 years.
