Water Main Breaks Decline in San Diego for Fourth Year in a Row

/in , /by

Increased maintenance efforts by the City of San Diego of its water system infrastructure is paying off for ratepayers. For the fourth year in a row, the number of water main breaks has decreased in the City of San Diego. Thirty-three water main breaks were reported in 2020, the lowest total in more than 15 years.

The City credits its aggressive multi-year program to replace aging pipelines for bringing the numbers far below the peak of 131 breaks in 2010.

“The City’s Public Utilities Department has worked very hard to improve the reliability of our water system infrastructure,” said Shauna Lorance, director of public utilities. “Our citizens benefit greatly from fewer main breaks because it means less water loss and lower emergency repair costs.”

San Diego’s continuing program to replace old cast iron water mains has played a major part in the decrease in breaks. Some cast-iron pipes had been in service for more than a century. Since 2013, the city has replaced approximately 180 miles of water pipelines. By 2025, the last 55 miles of cast iron water mains are scheduled to be replaced with water mains made of durable polyvinyl chloride.

Water infrastructure maintenance programs also deliver a benefit to our region’s overall economy. According to the Economic Policy Institute, $188.4 billion spent on water infrastructure investments over five years would yield $265 billion in economic activity and create 1.9 million jobs.

“Improving and maintaining our water infrastructure is an important part of our commitment to serving our customers,” said Lorance. “We will continue to provide reliable water services our customers deserve.”

City of San Diego public utilities crews routinely oversee preventative maintenance work to help determine potential leaks and breaks before they occur. Private contractors have completed the bulk of the pipeline replacement projects under the direction of the City’s Engineering and Capital Projects Department.

A new advisory offering details on a remote hacker’s attempted sabotage of an Oldsmar, Florida city water treatment plant has revealed a disregard for certain basic cyber hygiene best practices among employees. Experts say it’s an indicator that operators of critical infrastructure could use a serious infusion of security controls. However, due to budget restrictions, these controls may first require a thorough risk assessment and prioritization exercise.

Opinion: San Diego is Thinking Big — Scary Big

/in , /by /The San Diego Union-Tribuneby Michael Smolens Mentioned: San Diego County Water Authority

San Diego has pretty much shed its image as a big small town, at least by the measure of potentially transformative proposals that could reshape the region for decades to come. Some of them are big and exciting, some big and scary— and often they are both. All of them are costly in terms of dollars and, potentially, in their impact on the land.

Whether they are the right things to do will be endlessly debated, even after some come to fruition — if they get that far.

California’s Aging Dams Face New Perils, 50 Years After Sylmar Quake Crisis

/in , /by /Los Angeles Timesby Louis Sahagún

It was a harrowing vision of the vulnerability of aging California dams — crews laboring feverishly to sandbag and drain the lower San Fernando Reservoir, as billions of gallons of Los Angeles drinking water lapped at the edge of a crumbling, earthquake-damaged embankment that threatened catastrophe on the neighborhoods below. Although the 1971 San Fernando earthquake and the near failure of the Lower Van Norman Dam have given rise to construction improvements — the much newer Los Angeles Dam survived an equivalent shaking in the 1994 Northridge quake — the overwhelming majority of California dams are decades past their design life span.

A cyberattack on a Florida water treatment plant underscores the need for strong security protections at the municipal level, attorneys and industry professionals say.

A hacker gained access to an Oldsmar, Fla. city computer on Feb. 5 and changed the level of sodium hydroxide, also known as lye, local authorities said. It isn’t yet known whether the breach originated from the U.S. or from outside the country. The Federal Bureau of Investigation is working with local authorities.

A hacker’s botched attempt to poison the water supply of a small Florida city is raising alarms about just how vulnerable the nation’s water systems may be to attacks by more sophisticated intruders. Treatment plants are typically cash-strapped, and lack the cybersecurity depth of the power grid and nuclear plants.

Approximately 90% of Oceanside’s drinking water is imported. Pure Water Oceanside will create three to five million gallons of drinking water each day, enough water to provide 32% of the City of Oceanside’s water supply.

The water purification process uses reverse osmosis and advanced oxidation to create safe drinking water. The technology removes pharmaceuticals, chemicals, hormones, microplastics, and personal care products.

The project protects sensitive ecosystems by reducing the amount of water siphoned by imported water sources. It decreases the amount of recycled water discharged into the ocean, and uses half the energy needed to transport imported water, reducing greenhouse gas emissions.

Residents are kept up to date on construction impacts to streets and other infrastructure through several outreach efforts including an interactive construction map, detailed online schedule, regular newsletters, and virtual open house presentations live on the City of Oceanside’s YouTube channel, offering residents the opportunity to ask questions.

San Diego’s Infrastructure Deficit Is Really a Stormwater Deficit

/in , , /by /Voice of San Diego by Andrew Keatts

The infrastructure deficit that has hung over San Diego politics for years without meaningful intervention is perhaps better understood as a stormwater deficit.

Eight years ago, Mayor Todd Gloria, then Council president, pledged to craft an infrastructure-focused ballot measure for the 2016 ballot, to address the city’s crumbling roads, sidewalks, pipes and drains. That never happened, and the problem has only gotten worse. But the city now appears to be serious about pursing a measure to fund a specific, and massive, piece of the city’s infrastructure failure: its stormwater system.
