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.
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.

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.

The San Diego County Water Authority’s asset management team recently celebrated the completion of a comprehensive condition assessment of more than 27 miles of the agency’s oldest pipelines. The assessment was performed in record time over just 16 months.
The work was part of a package of rehabilitative efforts on a portion of the First Aqueduct, which includes Pipelines 1 and 2 in North San Diego County. Built in 1947 and 1952, the two pipelines deliver treated water to the region and were constructed using various materials, including reinforced concrete and steel.
Proactive asset management team makes critical repairs
As the pipelines were inspected, areas that required immediate attention were identified and repaired, thereby minimizing future disruptions to water service and impacts to the surrounding environment. Sections of the pipelines requiring future repairs were added to a list of upcoming projects prioritized by the risks and associated costs.
“The asset management team took advantage of scheduled pipeline shutdowns, and with careful coordination, assessment work was performed concurrently with other major rehabilitation efforts in the region,” said Martin Coghill, operations and maintenance manager at the Water Authority. “This innovative approach saved time and avoided unnecessary disruptions in service to our member agencies.”
Throughout the condition assessment process, Water Authority staff worked closely with staff from member agencies to coordinate work being performed in their service areas and any potential impacts. Proactive repairs are crucial to ensuring the reliability of the regional water supply.
Collaboration with multiple contractors to perform complex work
In 2016, a search was conducted to find the best technologies to perform critical assessments to maintain the reliability of the pipelines. It resulted in a multi-technology, multi-contract approach.
Diakont, based in Carlsbad, Calif., used its robotically-mounted technologies to inspect steel pipe sections. High-resolution LASER Profilometry and Electromagnetic Acoustic Transfer technology located internal and external corrosion defects that were then repaired by welding steel patches on the inside of the pipe. This method avoided costly excavations and environmental impacts.
Pipeline Inspection and Condition Analysis Corp., based in Edmonton, Alberta, brought its sophisticated Remote Field Technology to San Diego County to scan most of the reinforced concrete pipe using an innovative tool that moved through the pipe at a controlled speed. The technology had been previously used by the Water Authority and consistently demonstrated a high level of accuracy.

Pure Technologies, a Xylem company with an office in San Diego, deployed its Near Field and Remote Field electromagnetic inspection tools to assess portions of the reinforced concrete pipe. With a focus on lightweight components, both tools were successfully conveyed through the pipelines using personnel with rope and pulley support.

The focus on the Water Authority’s First Aqueduct is the latest chapter in the agency’s long-running strategy to assess critical pipelines and ensure the maximum lifespan is achieved with the most cost-effective methods. Proactive asset management efforts first began in the 1990s and were consolidated into the Asset Management Program in 2009. To date, more than 150 miles of the Water Authority’s total 310 miles of large-diameter pipelines have been assessed using cutting-edge technologies.
The asset management team collaborates with local, national and international organizations in the asset management and water infrastructure fields, focusing on knowledge sharing and asset life optimization.

The Metropolitan Water District of Southern California granted San Diego Gas and Electric an permanent easement on MWD property in Pala.
The MWD board vote Feb. 11 approves the granting of the easement including conditions. SDG&E will obtain a 12-foot wide easement along the northern edge of the MWD property in the 39000 block of Pala Temecula Road.
MWD’s Pipeline 6 currently conveys water from Lake Skinner to Anza Road at De Portola Road in Temecula. That 7-mile segment is considered the northern reach of Pipeline 6; the southern reach would extend from Anza Road at De Portola Road to the San Diego County Water Authority delivery point approximately 6 miles south of the Riverside County line.
A new pipeline inspection tool being used by contractors working for the Vallecitos Water District to determine pipeline integrity could become a standard tool saving time and money.
After nearly completing construction in 2008, developers walked away from the 500-acre High Point subdivision in the City of Escondido. Water facilities installed for the subdivision were left unused for ten years.
Two developers CalWest and TrueLife Communities recently decided to complete the project. They approached Vallecitos to determine what is needed to complete water service.
The mains for the project, made of ductile iron pipe, had not been used for ten years. Vallecitos needed to determine the condition of the pipes. Infrastructure Engineering Corporation and subcontractor PICA Corporation are now testing and assessing the integrity of the water main including the pipeline appurtenance (blow-offs, air vacs, and fire hydrants) connections to the main pipeline.

Several processes are included in the High Point Pipeline Assessment project. Crews insert a tool developed by PICA Corporation called a “SeeSnake” into the pipeline, and data indicates the condition of the pipes. The SeeSnake uses an electromagnetic method on iron pipes, which can “see” past cement mortar, epoxy, or polyethylene lining to detect and size any corrosion damage to the iron structure of the pipe itself.
The SeeSnake tool is pulled through the pipe at 17 feet per minute, delivering data as the inspection is being performed in real-time. The technology helps expedite information, saving time and costs by accelerating the process without sacrificing attention to detail. Vallecitos is then able to assess the pipeline’s wall thickness, potential iron loss, and any other anomalies to determine the condition of the existing pipeline.
See video demonstrating the SeeSnake pipeline assessment.
“Good decisions start with good information,” said Kris Embry, PICA regional manager. “Our ultimate goal in testing this new system is to quickly and efficiently secure accurate condition assessment information, allowing the Vallecitos Water District to address any weak links and prevent potential pipeline failures long before they happen.”
When the inspection is completed, the repair process begins.
Two water pipelines are being inspected for the condition analysis, one running along Woodland Heights Glen starting at Briar Patch Glen, and one running along Elderwood Glen, totaling approximately 3,067 feet. The larger 2,300 feet section of pipe is near the District’s existing Palos Vista.
Preventive measures save water and costs

Over time, pipelines are exposed to corrosion from aggressive soils, electrical currents, damage to coatings or linings, physical force, or other factors. The result could be a pipeline break which could case other infrastructure damage, interruption to water service, a loss of water, or monetary losses.
When an inspection finds corrosion, the affected section of iron pipeline is isolated, removed, and replaced by PVC pipe. Because iron pipelines can be susceptible to corrosion from multiple causes, they are no longer installed in the Vallecitos Water District.
The inspection found two badly corroded areas of pipeline and excavations verified the accuracy of the data. The Vallecitos Water District continues testing the new process and the accuracy of the data to determine whether to adopt the new technology for future working pipeline assessments.
