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

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.”

Fifty-five miles of pipeline replaced in next four years

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.

San Diego County Water Authority Completes First Aqueduct Project In North County

The San Diego County Water Authority has completed a major rehabilitation project on the historic First Aqueduct in North San Diego County, it was announced Thursday.

The project renovated and replaced dozens of structures on two large-diameter pipelines which delivered the first imported water to the San Diego region in 1947 and remains a part of the regional water delivery system. The construction contract for the project was worth approximately $30 million.

“The First Aqueduct delivered imported water to our region for the first time more than 70 years ago, and it remains critical to water supply reliability for our region to this day,” said Gary Croucher, chair of the authority’s board of directors. “Coordination across water authority departments and collaboration with our member agencies allowed us to complete this extraordinarily complex project and ensure these pipelines operate for generations to come.”

Year-End Deal Includes Major Energy, Environment Wins

While negotiators largely sidelined energy issues during months of stalled talks on COVID-19 relief, a number of significant energy and environmental provisions will hitch a ride on the year-end agreement set to pass today.

House and Senate leaders yesterday announced they had reached a deal on a $1.4 trillion fiscal 2021 spending omnibus, pandemic relief legislation and a number of major items that will ride along. Final text had yet to be released by publication time.

El Camino Real Infrastructure Project Reaches Milestone

The Olivenhain Municipal Water District project to replace aging water infrastructure along El Camino Real in Encinitas has now reached the halfway point. After getting underway in March 2020 at the start of the coronavirus pandemic, the project is making steady progress. District officials expect the entire project to be completed in Spring 2021.

During the El Camino Real Potable Water Pipeline Replacement and Green Bike Lane Striping Project, OMWD is replacing approximately 4,700 linear feet of existing 12-inch diameter potable water pipeline along North El Camino Real from Encinitas Boulevard to Garden View Road, and approximately 650 linear feet of existing 12-inch diameter pipeline between Via Molena and Mountain Vista Drive. Water service lines and fire hydrant laterals served by the existing pipelines are also being replaced.

The two pipelines were originally installed in 1961 and 1974, and were fast approaching the end of their lifespan.

El Camino Real infrastructure project – ensuring water supply reliability

The pipeline replacement will reduce water loss and prevent emergency shutdowns due to leaks. This is vitally important for water conservation and to ensure water supply reliability for businesses and residents.

“OMWD has a robust water loss prevention program in place which reduces costs associated with water loss and emergency repairs in addition to conserving one of our most precious resources,” said OMWD Board Director Christy Guerin. “This project is a big undertaking, but it is absolutely important to the health and safety of the community.”

“OMWD and the city work closely together to find opportunities like these where we can streamline projects and reduce the inconvenience  they may cause to residents,” said Guerin, who is also the vice chair of the San Diego County Water Authority Board of Directors and former Encinitas mayor and councilmember.

Bike lanes included in El Camino Real infrastructure project

The pipeline replacement is expected to be completed by the end of the year. The City of Encinitas’ green bike lane portion of the project will begin at that time.

The green bike lane portion of the project will provide traffic calming measures, including improvements to safety and mobility for bicyclists along North El Camino Real from Encinitas Boulevard to Leucadia Boulevard by restriping and narrowing travel lanes. In addition, green-colored striping will augment some areas on the bike lanes and new signage and pavement markings will be installed.

Olivenhain Municipal Water District is implementing the lane restriping portion of the project on behalf of the City of Encinitas as an efficiency measure, which is taking place concurrently with the pipeline replacement project.

Collaboration on infrastructure improvements

The two agencies have combined what would normally be two separate, unrelated infrastructure improvement projects into a single effort to improve operational efficiency and reduce the temporary inconvenience of disruptions to area residents and businesses.

“These improvement projects are important for the continued success and safety of the surrounding areas,” said Encinitas Councilmember Joe Mosca. “We understand that anytime you are working in the road, especially in high-traffic areas, there can be traffic and noise impacts. That is why the City of Encinitas and OMWD are working together closely to minimize the time we need to be out there and keep any impacts to the public at a minimum.”

At the start of the project, Encinitas requested that work be done at night to further reduce traffic impacts. During the stay-at-home order, work could be completed during daytime hours due to significantly reduced traffic levels. However, as traffic has returned to normal levels, the City requested work hours be shifted back to overnight.

Olivenhain Municipal Water District officials continue to work closely with Encinitas officials to monitor the project’s impact on traffic on a week-by-week basis and modify the schedule as needed. Both public agencies and the project contractor Teichert Energy and Utilities Group continue to adapt and respond to opportunities to mitigate impacts to the surrounding community while maintaining efficiency.

Tribes, Green Groups Sue Over Trump Rollback of Water Rights

The Environmental Protection Agency is being sued for the second time in a week over a rule that limits states’ ability to fight big projects such as pipelines, with tribes and environmental groups who fear damage to nearby waters taking the latest action in court.

The new suit, filed Tuesday on behalf of three different tribal groups and the Sierra Club, argues states and tribes have a right to place conditions on federal projects that could degrade waters within their borders or to reject them altogether.
