First Aqueduct Maintenance Shutdown Runs Jan. 23-Feb. 1

/in , /by

The San Diego County Water Authority’s First Aqueduct will be shut down periodically over the next three months for maintenance projects to ensure a safe and reliable water supply for the region. Two shutdowns on the First Aqueduct are scheduled from January through March, when portions of the aqueduct will be relined, along with other maintenance.

The Water Authority and its member agencies are coordinating to minimize impacts to residents and businesses, while servicing pipelines that are more than 65 years old.

Customers of these affected retail agencies during the Jan. 23-Feb. 1 shutdown should check with their local water utility if they have questions about localized impacts: Fallbrook Public Utility District, Rainbow Municipal Water District, Rincon del Diablo Municipal Water District, Vallecitos Water District, Valley Center Municipal Water District, Vista Irrigation District, and the Yuima Municipal Water District.

“Work to proactively upgrade and maintain our water delivery system in coordination with our member agencies ensures the continued safe and reliable supply that serves the region’s 3.3 million residents and our $268 billion economy,” said Eva Plajzer, the Water Authority’s director of operations and maintenance. “Taking care of this critical infrastructure during the shutdown season extends the life of the aqueduct and reduces the cost of replacement.”

Maintenance work on pipelines is scheduled during low-demand periods to minimize impacts on water service.

The other scheduled shutdown on the First Aqueduct is February 27 to March 8, which will also impact the Helix Water District and the cities of San Diego, Poway and Ramona.

The historic First Aqueduct was constructed in the 1940s with Pipeline 1 and in the 1950s with Pipeline 2. On November 28, 1947, the first Colorado River water flowed south from Riverside County for 71 miles into the City of San Diego’s San Vicente Reservoir via the First Aqueduct.

The Water Authority’s Asset Management Program is a key element of providing safe and reliable water supplies to the region. The agency continually assesses and inspects its 310 miles of large-diameter pipelines, which provide treated and untreated water to 24 member agencies in San Diego County. The program is widely recognized for pioneering work – including a patented inspection device – that promotes water affordability by avoiding costly unplanned disruptions in service.

As assets age, the Water Authority proactively replaces and repairs them to minimize impacts to member agencies and the public. Investments in the latest inspection technologies, including electromagnetic scanning, robotic inspections and 3D tunnel inspections help the Water Authority’s asset management team detect defects in pipelines and related facilities. Identifying potential issues early avoids more costly fixes later.

Water Authority Delivers Emergency Water Supply to Tijuana

/in , /by

Fast action by the San Diego County Water Authority and its partners is helping maintain water service in Tijuana after problems with the city’s aqueduct emerged in December.

Emergency water deliveries started last week after a coordinated effort between the Water Authority, Otay Water District, and Metropolitan Water District of Southern California (MWD). The typical multi-month approval process was compressed into a few days to avoid additional water supply shortages in Tijuana.

Director Jim Madaffer Elected Vice Chair of the Colorado River Board of California

/in , /by

San Diego County Water Authority Board Member Jim Madaffer has been elected vice chair of the Colorado River Board of California (CRB), which represents California in river management discussions with other Basin states, federal agencies, tribes, and Mexico.

Madaffer, the Water Authority’s CRB representative since 2019, will serve a four-year term as vice chair following his election on January 11 during the CRB meeting in Ontario. He will serve alongside Imperial Irrigation District Board Vice President JB Hamby, who was elected chair.

“I look forward to working with Chair Hamby and the rest of the Colorado River Board to both protect California’s water supplies during these challenging times and to work collaboratively to keep the river flowing for all users,” said Madaffer, a former chair of the Water Authority Board. “It is essential that California agencies unite to uphold the Law of the River as we seek solutions with the widest possible benefits.”

Established in 1937, CRB consists of agency representatives from the Water Authority, IID, Metropolitan Water District of Southern California, Coachella Valley Water District, Palo Verde Irrigation District, and the Los Angeles Department of Water and Power. Additional representatives include the directors of the California Department of Water Resources and Department of Fish and Wildlife, along with two public representatives.

CRB’s role has been pivotal in protecting the state’s share of the river during this period when two decades of drought have caused a sharp supply/demand imbalance, leading to a severe decline in water levels in the river’s two main reservoirs, Lake Mead and Lake Powell.

Led by CRB, California has proposed conserving up to 400,000 acre-feet annually through 2026 to support the river. Though that conservation will not affect the San Diego region’s high-priority Quantification Settlement Agreement supplies, the region is continuing to take active steps to conserve as it has over the past three decades.

“The San Diego region is committed to doing our part to be good stewards of our water supplies,” said Water Authority Board Chair Mel Katz. “We also believe in working collaboratively with all stakeholders on the river, and Jim’s leadership on the Colorado River Board in his new role as vice chair will only advance those efforts.”

Turn Off Irrigation During and After Rainstorms

/in , /by

A series of storms bringing much needed rain to the San Diego region is also a reminder for residents and businesses to turn off irrigation systems when wet weather is predicted and for at least a week after significant rainfall.

While a series of atmospheric rivers is boosting Sierra snowpack and easing dry conditions statewide, there is still a long way to go to overcome three extremely dry years. Water-saving actions today can help conserve more of our most precious natural resource for when it’s needed most.
