Historic Pipeline Project Boosts Long-Term Water Reliability

/in , /by

San Diego County Water Authority crews successfully completed the first of three coordinated shutdowns of the First Aqueduct in early March to launch a major renovation of dozens of structures on two pipelines, including the historic Pipeline 1 that first delivered imported water to the region in 1947.

The series of shutdowns was carefully planned for nearly four years to minimize impacts on the community and retail water agencies during retrofits of Pipelines 1 and 2, which comprise the First Aqueduct.

“The First Aqueduct has been a very reliable source of imported water for more than 70 years,” said Chris Castaing, operations and maintenance manager at the Water Authority. “These critical upgrades will make sure we can operate and maintain the pipelines for another several decades to transport water to the region for future generations.”

Started during the Water Authority’s 75th anniversary year, the $30 million First Aqueduct structure and lining renovation project is among the most complicated pipeline retrofits in agency history.

During the next two years, upgrades include replacing the lining on the steel pipe sections; removing 19 associated structures; and retrofitting 41 structures – all without jeopardizing water service to the region.

Project will enhance reliability and flexibility of regional water system

Pipeline structures that will be rehabilitated include valves, blowoffs, pump wells and access ways.

Approximately 4 miles of failing pipeline lining on the steel pipe sections will be carefully removed and replaced with new cement mortar lining. Cement mortar is the preferred material, because it protects the interior of the steel pipe from corrosion and premature failure, has a longer life, and is easier to maintain. The project also will add redundant connections to six flow control facilities between the two pipelines, greatly improving the aqueduct’s operational flexibility.

During the first shutdown between February 24 and March 5, crews isolated sections of the pipeline and took them out of service so work can be safely performed on those sections throughout the year. In late 2019, a second 10-day shutdown will allow crews to switch flows to the upgraded sections of pipe and isolate other sections for repairs.

In addition to completing the First Aqueduct structure and lining renovation project, the Water Authority also will perform assessments of 27 miles of the pipeline to determine if additional upgrades will be needed.

Federal Legislators Announce $15Mil For Water Infrastructure Improvements At U.S.-Mexico Border

OPINION: Jerry Brown’s Four Biggest Incompletes

/in , /by /The San Diego Union-Tribune

As Gov. Jerry Brown leaves office amid high praise and some criticism, it’s impossible to give him anything but a grade of incomplete on several major issues. The most prominent of these is criminal justice reform, where Brown has sought huge changes to the overly punitive system he helped create in his first stint as governor. His decision to sign the Uniform Determinate Sentencing Act in 1976 was a major early step in an excessive war on crime that peaked in 1994 when California voters passed the nation’s harshest “three strikes and you’re out” law.

San Diego City Council was recently warned about the damage an earthquake can cause to the region, specifically on the county’s water system. “Strengthen their water system, make that long-term investment,” seismologist Lucy Jones said of the city’s aging water infrastructure. Jones recently spoke with city council leaders about improvements she’s helped develop for Los Angeles’ infrastructure. “[It] contributes to a much more difficult time getting your city back up and running,” Jones said.

Alvin Thoma’s youngest son was born the year his employer, Pacific Gas & Electric Co., began the process of renewing the license for its Upper North Fork Feather River hydropower facility in northern California. His son is 19 years old now. The facility, however, is still undergoing relicensing. “For me, that’s a mental image of just how long it takes to go through this process,” Thoma, a director of power generation at PG&E, which runs one of the largest hydro systems in the country, told Bloomberg Environment.

A $25.3 million Pipeline 5 relining project is under way in North County to improve the reliability of the San Diego region’s water delivery system. The project involves rehabilitating approximately 2.3 miles of one of the San Diego County Water Authority’s regional wholesale water pipelines in eight segments along a 9.5-mile stretch through the community of Fallbrook. Construction work will be done in phases and completed in summer 2019. When finished, the Pipeline 5 Relining Project will help extend the service life of this vital piece of infrastructure for more than 75 years. Generally, relining construction rehabilitates segments of pipelines based on their age and the need for improvements.

President Donald Trump signed a bipartisan water infrastructure bill into law on Tuesday, authorizing billions of dollars for state-level projects aimed at improving the nation’s rivers, harbors, and drinking water. The law will also defund programs Congress deems “inefficient,” the Hill reports. Provisions that made the cut include funding for studies on wetland restoration and risk management in flood-prone areas, such as Tangier Island, Virginia; extending a program to improve contaminated drinking water in Flint, Michigan; prioritizing lead testing in low-income schools; and requiring the Environmental Protection Agency to appoint at least one employee to serve as a “liaison to minority, tribal, and low-income communities.”

OPINION: Proposition 3 Provides Needed Funds To Improve Valley’s Water Infrastructure

/in , /by /The Fresno Beeby Jason Phillips

Imagine the Silicon Valley without technology or Hollywood without the entertainment industry. Just as those areas depend on their foundations for prosperity, our ability to capture, move and store water for agriculture is a determining factor for our region’s prosperity. In the southern San Joaquin Valley, water is our lifeblood. When it flows, communities prosper. Without it, jobs disappear, families leave, services evaporate and communities suffer. Even if your job doesn’t have anything to do with agriculture, if you live in our Valley, water matters.
