Say the word “library,” and your word association is likely “books.” But across the country, including in San Diego, many libraries also lend other important items, including seeds for home gardens.
Many of these “seed libraries“ aren’t actually conventional libraries: They may be a service organized by neighborhoods, schools or other kinds of organizations. The common factor is that they are all a free community resource that offers locals the opportunity to grow everything from fruits and vegetables to flowers and native plants. All they ask is that patrons return the “borrowed” seeds by way of harvesting new seeds from the grown plants.

San Diego County’s water world hasn’t had much good news lately, with looming budget problems and whopping rate increases.
Well, here’s some: The state’s new mandatory water conservation plan won’t require big reductions locally. That’s due mostly to decades of spending on recycling, desalination, storage, conservation and imported supplies.

As soon as the Water Authority’s Martin Coghill heard about a catastrophic pipeline failure in Calgary two weeks ago, he knew how distressing it could be.
“When they’re in a situation where they call us for help from over 1,600 miles away, that’s a bad, bad day,” Coghill said.
The Water Authority was quickly able to send the final pieces of the infrastructure puzzle to Calgary to speed the city’s repairs. But Coghill, the Water Authority’s asset management manager, knows that similar problems could quickly impact San Diego County.
“In our aqueduct system, there are 80 miles of pre-stressed concrete cylinder pipe,” Coghill said. “That’s the same type of pipe that suffered catastrophic failure in Calgary.”
See how the Water Authority helped keep the water flowing in Calgary.
Pipeline failure potential in San Diego
The Water Authority experienced the same kind of problem in 1979, when pre-stressed pipes failed in the region for the first time, impacting the county’s water supply.
In response to that failure, the Water Authority spent the past 42 years relining 48 miles of pre-stressed pipe – or 60% of that type of pipe in the system – through a process called steel relining. That ongoing investment has significantly decreased the risk to the region’s water supply.
The catastrophic break in Canada led many across North America to recognize the unique space that water infrastructure plays in their daily life. As Kerry Black, a civil engineering professor at the University of Calgary said in a CBC interview, “when it breaks, it’s the first thing you’ll complain about but it’s the last thing you want to pay for.”
Across the United States, the potential for pipeline failure is an ongoing weakness, according to the American Society of Civil Engineers. It gave the nation’s water utilities a C- grade in its most recent national infrastructure report card in 2021. “Unfortunately, the system is aging and underfunded. There is a water main break every two minutes and an estimated six billion gallons of treated water lost each day in the U.S., enough to fill over 9,000 swimming pools,” said ASCE.

Coghill knows that even with all the advancements and investments in inspection and monitoring technologies, there are still gaps in the Water Authority’s ability to see problems coming. “Despite these technologies, we only have tools to actively monitor about two-thirds of the things that can go wrong with pre-stressed pipe,” Coghill said. “We’re not immune from a failure.”
For the Water Authority, protecting against a break in San Diego County happens on two parallel tracks and involves investing in critical infrastructure upgrades and testing.
“There are two roads we go down,” Coghill said. “One is a proactive approach in which every two years we re-evaluate what sections of the pre-stressed pipe are the next priorities based on risk and consequence of failure. That is put into the recommendation for the upcoming budget cycle for rehabilitation using steel liners. The other one is a more reactive approach, which I call the ‘imminent failure watch.’”
Modern tools track down early warning signs
That’s where the Water Authority’s installation of acoustic fiber optic cable allows engineers to hear a localized problem starting in real time, allowing the Water Authority to shut things down to fix the problem, and ideally with enough time to prevent a break.
This parallel track methodology has served the organization well since 2006—the last time a major failure of a prestressed pipe occurred—and in 2022, in response to data recorded by the acoustic monitoring system, identified the need for an urgent repair in the Bonsall area.
Coghill summarized the risks for our region. “Provided that we maintain a commitment to steel relining our prestressed pipe, and we maximize the use of available technologies, we are doing everything we possibly can to manage this type of pipe.”

Carlsbad’s desalination plant, which provides 10 percent of San Diego County’s drinking water, will get $19.4 million for the construction of its new seawater intakes as part of $142 million in federal grants for water projects throughout the West.
Construction of the new facilities began in January 2023 at the Claude “Bud” Lewis Carlsbad Desalination Plant, a spokesperson for the San Diego County Water Authority said Friday. The new intake screens will be placed in operation this fall, and the full project should be finished in early 2025.

Farmers in San Diego County say proposed water quality regulations that establish updated general waste discharge requirements for commercial agricultural operations are burdensome, costly and duplicate work by growers participating in other regulatory programs.
Tasked with protecting water quality, the San Diego Regional Water Quality Control Board on March 29 released a proposed draft that creates new monitoring and reporting requirements for nitrogen applications and removals. It also identifies paths to compliance for individuals or use of third-party programs to help farmers achieve the order’s objectives.

Much like your body, public infrastructure needs constant care and attention. Check-ups, tests, and consistent monitoring help you stay on top of your health. It’s similar with the regional water infrastructure, with 1,400 structures, 308 miles of large pipelines, a dam, a water treatment plant, as well as pump stations and hydroelectric facilities. All pieces working together as one integrated system, much like your body, yet all of it aging, day by day.
Monitoring and assessing the condition of the regional water infrastructure is the responsibility of the “doctor” of asset management, Martin Coghill, Operations and Maintenance Manager at the Water Authority, and his staff.
During the last week of May, members of the Water Authority’s Board of Directors were treated to a showcase of technologies, as well as incredible stories from Coghill and his staff about their use – and how they help the organization save time and money.
A history of innovation
The Water Authority has long been on the cutting edge of testing and utilizing the latest technology to help assess the condition of its system. This is important because Water Authority pipelines no longer traverse formerly agricultural and rural settings. San Diego County has urbanized quite a bit over the last half-century, and a ruptured pipeline in a now urban setting is likely to threaten property and the livelihoods of those living nearby.
In 2006, a large-diameter pipeline ruptured in the western portion of Mission Trails Regional Park. Thankfully, damage wasn’t worse, not only because of the remote location, but also thanks to the rapid response of Water Authority staff that closed valves to stop the flow of water.
Though the break was unfortunate, it provided critical data to the Water Authority, who had recently installed a new technology inside the pipe – an acoustic fiber optic cable. That AFO cable heard pings as the pipeline started to fail and recorded that data. As a result, that type of cable has been installed in other pipelines throughout San Diego County to help monitor their health.
Now, Coghill and his team know what it sounds like when a section of pipe is in distress. That technology works alongside other technologies to provide critical data about the condition of the pipe, which then helps Coghill and his staff develop a recommendation for repair before the pipe fails.
In the 1980’s, Water Authority staff thought up an ingenious solution to reline a certain kind of pipe called Prestressed Concrete Cylinder Pipe with new steel liners. That repair solution continues to be the preferred solution by the Water Authority and other water agencies around the world to repair those sorts of pipes. The bonus is that this method of repair saves the agency millions of dollars each year and is less intrusive than digging up and replacing those sections of pipelines.
An eye to the future
This innovative culture continues to breed new, cost-effective solutions.
One historical challenge has been assessing the condition of the pipe while it’s in service. In the past, pipelines had to be dewatered before crews could enter them to deploy tools and assess their condition. One fairly new technology that allows the pipelines to stay in service – saving water and money – are acoustic leak detection devices. These tools are inserted into a live pipe and travel with the flow of water. They can detect sounds of active leaks.
Another challenge has been “getting eyes” on the inside of the approximately 1,400 structures along the pipelines. In order to inspect them on a routine basis, staff have had to climb down into the structures and take photos. The confined space makes this task hazardous and difficult. Recently, one of Coghill’s staff developed a tool using a 360-degree action camera mounted on a telescopic pole. Staff was able to save the organization money by purchasing the components separately and assembling them. This innovative solution saved the Water Authority nearly $9,000, which does not include the staff time saved from having to climb in and out of each structure to take the same photos.
These new technologies and tools produce large amounts of very important data. It takes Coghill and his team many hours to comb through it, crunch the numbers, and analyze it to develop recommendations for repairs or replacement. His team is considering other data storage and reporting options, including use of artificial intelligence and/or other software that could streamline efforts to analyze the data.
While the technology showcase was just a one-day event, the use of the featured technologies, along with monitoring and condition assessment efforts, continue, 24 hours a day, 7 days a week. At the heart of it all lies a team and their tools embedded in a culture of innovation – an investment for the future that helps safeguard our region’s long-term sustainability.

The awards recognize large-scale improvements to facilities and landscapes that achieve significant water savings. The four projects honored in early May are expected to save 200 million gallons of water annually. Projects are also recognized for technology innovations, environmental stewardship, and their focus on water sustainability.
Jamacha Park is a 64-home community. The HOA worked with MWD, the San Diego County Water Authority, and the County of San Diego’s Watershed Protection Program to replace 58,000 square feet of grass with sustainable landscaping, including climate-appropriate plants.

“I hope the project that we have done will show other communities what is possible. There is a way to get water savings and still have a beautiful landscape everyone can enjoy,” said Jamacha Park HOA Board President Mary Kay Sieckman.
The HOA board, community residents, and landscape professionals worked together on the landscape makeover. The newly beautified community spaces are accessible to all residents while reducing water use.
Jamacha Park leaders achieve a long-time goal
Sieckman said the HOA learned about these programs through its property management company. “When the board members heard about it, they jumped at it. They were very excited because it would be a step forward toward a long-time goal we knew needed to be done.”
See a video featuring Jamacha Park HOA Board President Mary Kay Sieckman describing the landscape makeover process.
The project has been so successful that the HOA plans to replace additional turf, eventually removing a total 100,000 square feet of grass for a potential water savings of 4 million gallons annually.
The Jamacha Park HOA received funding and assistance through MWD’s Turf Replacement Rebate Program available through the Water Authority and the County’s Landscape Optimization Service. Working with the County’s Watershed Protection Program, residences and businesses in unincorporated areas of San Diego County can be eligible for enhanced water-use efficiency rebates.

To make the process of applying for rebates easier and maximize the return on investment, the County added a Landscape Optimization Service (LOS), a unique technical assistance program for large-scale landscaping projects. It is part of the Waterscape Rebate Program, which helps residential, commercial, and agricultural customers in unincorporated areas to make landscape upgrades that improve the region’s climate resilience and reduce the flow of pollutants into waterways.

County of San Diego Land Use Environmental Planning Manager Scott Norris says the LOS program helps applicants navigate the requirements, overcome any barriers to participation, and maximize their eligibility. “Often HOAs just need a bit of help to get started. We have worked with more than a dozen HOAs and more than half are coming back to complete additional turf removal projects because they see the value for their communities.”
Multiple benefits from sustainable landscapes

Sustainable landscapes produce multiple benefits including reduced water use, enhanced biodiversity, increased stormwater retention, and decreased run-off.
IMPACT:
58,000 square feet of turf removed
270,000-gallon reduction in irrigation runoff annually
12% savings in water use in the first year
$232,000 in utility incentives
New landscape features include boulders framing walkways. Photo: MSE Landscape
Water customers in unincorporated San Diego County can determine their eligibility at SanDiegoCounty.gov/WatershedRebates. More information on the Landscape Optimization Service can be found here. The program is currently recruiting new participants.
The Waterscape Rebate Program helps to protect local waterways by reducing pollutants that enter storm drains. When irrigation systems overflow from landscaping, runoff may carry pollutants like pesticides, herbicides, and fertilizers into the storm drain system and cause the same negative effects as runoff from rainfall. Reducing turf helps reduce irrigation use and runoff. HOA landscapes are potentially significant contributors.
