San Diego to Spend up to $100 Million for Dam Safety Consultant Over Next 10 Years

/in , /by /CBS 8

In recent years, the city of San Diego has released more than 11 billion gallons of freshwater from city-owned reservoirs into the ocean.

It has been done because many of the dams holding the water in are failing and have been placed on water restrictions to prevent a breach.

Now, the city of San Diego is looking to hire an outside consultant to manage its dam safety program for the next ten years at a price of up to $100 million.

The Water War Between the US and Mexico

/in , /by /The Week USby Devika Rao

The U.S. and Mexico are experiencing another border dispute, and this one is about water. The conflict stems from an 80-year-old treaty where the countries agreed to share water from the Colorado River and the Rio Grande. However, because water is in more demand but scarcer than ever, sharing has not been going to plan.

The U.S. and Mexico signed a treaty in 1944 stipulating that Mexico send 1.75 million acre-feet of water to the U.S. every five years from the Rio Grande, and the U.S. send 1.5 million acre-feet of water to Mexico from the Colorado River each year. But water levels are lower than ever, and Mexico has “sent only about 30% of its expected deliveries, the lowest amount at this point of any four- or five-year cycles since 1992,” said Reuters.

America’s Drinking Water is Facing Attack, with Links Back to China, Russia and Iran

/in , /by /CNBCby Trevor Laurence Jockims

The city of Wichita, Kansas, recently had an experience that’s become all too common — its water system was hacked. The cyberattack, which targeted water metering, billing and payment processing, followed the targeting of water utilities across the U.S. in recent years.

In going after America’s water, hackers aren’t doing anything special. Despite rising fears of AI use in cyber threats, the go-to criminal way into systems remains preying on human foibles, be it via phishing, social engineering, or a system still running on a default password — “old school” cyberattacks, according to Ryan Witt, vice president of cybersecurity firm Proofpoint.

Drinking Water of Almost a Million Californians Failed to Meet State Requirements

/in , /by /Cal Mattersby Rachel Becker

Almost 400 water systems serving nearly a million Californians don’t meet state requirements for safe and reliable drinking water supplies — and fixing them would cost billions of dollars.

More than two-thirds of these failing water systems serve communities of color, and more than half are in places struggling with poverty and pollution, according to an annual assessment released today by the State Water Resources Control Board.

Cost of Bringing Clean Drinking Water to California Communities Estimated at $11.5 Billion

/in , /by /Los Angeles Times by Ian James

California has made significant progress helping small communities address problems of contaminated drinking water, but the costs of bringing safe tap water to hundreds of communities over the next five years will run more than $11.5 billion, according to a new state estimate.

In a newly released report, the staff of the State Water Resources Control Board estimated that at the start of this year approximately 913,000 Californians depended on public water systems that are failing to comply with drinking water regulations, while an additional 1.5 million people depended on water systems that are determined to be “at-risk.”

Groundwater Declines in the U.S. Southwest

/in , /by /NASA Earth Observatoryby James R. Riordon

Record snowfall in recent years has not been enough to offset long-term drying conditions and increasing groundwater demands in the U.S. Southwest, according to a new analysis of NASA satellite data.

Declining water levels in the Great Salt Lake and Lake Mead have been testaments to a megadrought afflicting western North America since 2000. But surface water only accounts for a fraction of the Great Basin watershed, which covers most of Nevada and large portions of California, Utah, and Oregon. Far more of the region’s water is underground. That has historically made it difficult to track the impact of droughts on the overall water content of the Great Basin.

Calgary Water Pipes are Vulnerable to Failure

/in , /by /The Globe and Mailby Jude Brocke Mentioned: San Diego County Water Authority

The infrastructure network that transports safe, clean water around Calgary contains 187 kilometres of pipe similar to the line that suffered a catastrophic break more than two weeks ago, forcing the city’s residents and businesses to cut back on water use and prompting a massive emergency fix-it job.

The city’s Bearspaw South Feedermain, which ruptured June 5, is a prestressed concrete cylinder pipe (PCCP), a design used elsewhere in Calgary and across North America. This type of pipe is known to be vulnerable to major failures, although its engineering has improved since the late 1970s and determining what, precisely, caused the feedermain to crumble may be impossible.

Adel Hagekhalil: Southern California’s Embattled ‘Water Doctor’

/in , /by /Los Angeles Timesby Ian James

As general manager of the Metropolitan Water District of Southern California, Adel Hagekhalil has overseen a public agency that’s responsible for supplying the water that 19 million people drink. And he has been playing a leading role in efforts to transform how Southern California manages water, one of the most consequential issues the region faces as climate change continues to upend the water cycle.

His influence in this critical sphere currently hangs in the balance. Earlier this month, the water district’s board placed Hagekhalil on leave as it investigates harassment allegations by his chief financial officer that he denies. With him sidelined, some of his supporters are concerned the policies he has been pursuing could be affected.

California Judge Grants Injunction in Water Conveyance Project

/in , /by /Courthouse News Serviceby Alan Riquelmy

A Sacramento County judge on Thursday ruled in favor of several water districts and local governments over California’s planned delta tunnel project that would divert water from Northern California to the south of the state, saying that exploratory work can’t continue until the state completes a necessary certification process.

The decision by Superior Court Judge Stephen Acquisto is a win for the groups that had argued the state Department of Water Resources hadn’t completed all documentation required by the California Environmental Quality Act and complied with the Delta Plan.
