Innovative Water Deal Deliver Benefits to Regional Ratepayers

December 4, 2024/in Agency News, Features, News, Uncategorized, WaterSmart Living /by Jordan Beane

For the second year in a row, the San Diego County Water Authority and its partners have struck a deal to conserve water in Lake Mead, support the long-term sustainability of the Colorado River and save local ratepayers money.

The agreements between the Water Authority, the Imperial Irrigation District, and the Metropolitan Water District, with funding from the U.S. Bureau of Reclamation, are designed to promote voluntary water conservation. The 2024 agreement was announced during a meeting of the Colorado River Board of California at this year’s Colorado River Water Users Association’s conference in Las Vegas.

As a part of these deals, the Water Authority agreed to leave 50,000 acre-feet of water from its Quantification Settlement Agreement supplies in the Colorado River, helping California meet federal conservation goals.

The 2023 agreement between the three parties was the first of its kind. The 2024 deal will save San Diego County ratepayers approximately $20 million, which will be applied to 2026 wholesale water rates.

“For the second year in a row, the Water Authority and its partners have struck a deal to conserve water in Lake Mead and save our local ratepayers approximately $20 million,” said Water Authority Board Chair Nick Serrano. “This is a win-win for all of us and demonstrates how the Water Authority is strategically using its assets to help protect ratepayers and the Colorado River through innovative thinking.”

The Water Authority’s efforts are part of a larger commitment by California water users to protect the overtaxed Colorado River, including plans to save at least 400,000 more acre-feet in 2025 after conserving more than 1.2 million acre-feet over the last two years.

“It is really a model partnership and collaboration between states and local entities and the federal government,” said U.S. Bureau of Reclamation Commissioner M. Camille Calimlim Touton.

California’s efforts have led to the equivalent of 16 feet of water being added to Lake Mead in two years, providing much-needed stability to the entire river system as the seven Basin states work with the federal government to create a post-2026 operations plan for the river.

“Our collective achievements not only have made a profound impact on Lake Mead today, they also illustrate the can-do spirit that the Water Authority and our partners bring to future conservation work on the river,” said Colorado River Board Vice Chair and Water Authority Director Jim Madaffer. “We are both proud of what we have accomplished and committed to delivering additional solutions for the Southwest in the years ahead.”

The Colorado River Basin is the most important water source in the West, providing water for more than 40 million people and generating hydropower in seven U.S. states.

The Water Authority will continue to pursue other water transfers and exchanges to maximize the value of San Diego County’s water resources and minimize the cost to local ratepayers. Those steps include budget cuts, project deferrals, debt refinancing, increasing grant funds and restructuring rates.

The Solana Center For Environmental Innovation offers a rain barrel purchase program for City of San Diego residents. The Solana Center will help set up your household for water harvesting success. Order your discounted rain barrel by January 11, 2025, for pick up at the North Clairemont Recreation Center on Saturday, January 25. You can attend a free rainwater harvesting workshop at 10 a.m. More information is available on the Solano Center website.

County of San Diego rebate programs

The County’s Waterscape Rebate Program will host free rainwater harvesting workshops in 2024. Workshops teach residents how to capture rainwater to supplement your irrigation needs, save money on water bills, and protect our region’s environment by preventing pollutants from spilling into regional watersheds.

Workshop dates are expected to be scheduled soon. For future workshops, check the County of San Diego Waterscape Rebate Program website.

Residents in unincorporated areas of San Diego County may be eligible to receive a free rain barrel. Workshop participants in incorporated areas can check their rebate eligibility on the San Diego County website’s interactive map.

If you live in unincorporated San Diego AND receive your water from the San Diego County Water Authority and its member agencies, you are eligible for ALL rebates listed under the County program.

The County of San Diego Watershed Protection Program (WPP) partners with the San Diego County Water Authority and Metropolitan Water District of Southern California (through SoCal WaterSmart) and can assist residents in determining which program benefits are available.

Reduce water use to preserve the environment and save costs

During San Diego County’s limited periods of rainfall, any rainwater captured from your roof and property saves money. It also helps the region maintain its water supplies.

In addition to rain barrels, directing downspouts to fill containers lets you choose how to use the rainwater you capture. The overflow should empty onto your yard or a landscape feature to infiltrate the excess flow into the soil. Rain chains can assist with this.

The County is committed to protecting the water quality in creeks, streams, and coastal areas. Runoff from irrigation, storms, and even faulty septic systems can pollute our waterways and threaten public health.

When businesses and households make changes to reduce water use and use rainwater in their landscapes, we preserve healthy, safe waterways and more reliable water supplies while achieving cost savings.

How rain barrel rebates work

After you make your purchase of rain saving containers and any other items eligible for rebates and have installed them, you can apply for rebates. Current rain barrel rebates are $35 and limited to two per household for most San Diego County residents. You can submit for multiple projects. Learn more at SoCal Water Smart.

Conserve water for landscape maintenance

Even light rain can provide enough water for later use. A roof with a 2,000-square-foot surface area can capture 300 gallons from only a quarter inch of rain.

Stored water can be released gradually into landscaping between winter rainstorms, building up the soil sponge and ensuring that native plants get adequate water during the winter months when they need it most. If you need additional water in the summer and capture enough of it during the winter, you may be able to use your stored water for supplemental irrigation.

Visit the Solana Center For Environmental Innovation website for additional details on conservation rebate programs and to order rain barrels.

Report Shows Positive Impact of Manufacturing on Region

October 31, 2024/in Achievements, Features /by Jordan Beane

A new report from the San Diego Economic Development Corp. (EDC) shows the positive effect of the manufacturing sector on our regional economy. With $47 billion in economic impact across San Diego County, including more than 120,000 good-paying and low-barrier jobs, manufacturing is a cornerstone industry from San Ysidro to Oceanside.

Few of those jobs – or other economic benefits – would exist without the safe and reliable water supplies provided by the San Diego County Water Authority and its member agencies. While sustainable water sources are often taken for granted, they support virtually every manufacturing process in one way or the other, from the region’s famous craft beers to the water used in biotech labs.

To San Diego Councilmember Raul Campillo, these kinds of jobs have a huge impact for workers in our region. “That means you’re putting kids through college,” Campillo said at an event unveiling the report. “That means you’re inventing devices that save lives. That means you’re bringing people here to see what San Diego has to offer and that helps everybody.”

The EDC’s report – sponsored by the Water Authority — highlights the outsized impact of small businesses in the manufacturing sector, careers that pay 31% more than the average regional salary, and the broad range of related industries helping to grow manufacturing in San Diego County.

Yet it’s not just about the sector itself but the broader impact it has across the region. “When factoring in supply chain activities and consumer spending from wages, the sector supports an additional 146,000 jobs across the county,” the report said. “This means that for every 100 jobs added in manufacturing, another 121 jobs are created elsewhere in the economy.”

“Nearly 1 in 10 private sector jobs in the region is a manufacturing job,” Eduardo Velasquez, EDC Senior Director, Research and Economic Development, said.

While the high cost of housing and the lack of developable space does hinder the sector’s ability for bigger growth, the companies in the sector are among the most innovative in the region and are dedicated to finding unique ways to expand even with those constraints.

The transformation from thirsty turf to a beautiful habitat is the 2024 Sweetwater Authority Landscape Contest winner.

The regional WaterSmart Landscape Contest allows residential water agency customers to showcase their waterwise landscapes. Customers submit applications to their respective water agencies, and each agency selects a landscape that best meets the elements of waterwise landscaping. These elements include:

Overall attractiveness
Appropriate plant selection and maintenance
Design
Efficient irrigation methods

Patient Planning and Prep Pays Off

They planned and worked hard to eventually transform their front yard from thirsty turf into a space that not only required little water but also provided beauty and habitat.

“This rationale behind our landscape project was a no-brainer: we live in a desert, we need to conserve water, and we wanted a functional yet eye-catching design, said Laura and Jaime Cervantes.

“Although we’ve lived in our house for 11 years, it took us a long time to save up for and to plan our ideas, but we finally completed everything about two years ago.”

The transformed landscape includes low-water use plants such as Kangaroo Paw, Orange Bulbine, and Coral Pink Sage, along with various succulents. The yard also features a beautiful Palo Verde tree, which provides nice shade.

Plant Selection Drives Design Choices

The Cervantes family had a large front yard for their canvas, composed mainly of old turf.

“We transformed it by replacing the old turf with a much smaller area of drought-tolerant Bermuda grass,” they explained. “We wanted plants that not only require little water but also provide beauty and habitat.”

The new walkway was created from flagstone and decomposed granite. A winding dry riverbed retains water overflow from numerous rain barrels.

A new fence allows views of the new landscape both inside and outside to complete the picture. It also acts as a graffiti deterrent due to the hog wire and wood construction.

Unexpected Benefits From Landscape Makeover

The Cervantes irrigate their yard using rainwater captured from their 14 rain barrels. They water by hand to get out into the sunshine and enjoy the beauty of their landscape. “We have no automated system – I like to get out in the yard and in the sunshine, so watering by hand is something I really enjoy,” said Laura Cervantes.

The winners reported an unexpected and pleasant outcome of their new yard from the nice comments and conversations it elicited from people walking by.

“It is a great feeling to not only add beauty to our neighborhood but also to know that we are able to contribute in our own small way towards being good stewards of the environment,” said Laura and Jaime Cervantes.

Membrane Tech Important Piece of Water Future

October 21, 2024/in Achievements, Features /by Jordan Beane

The November edition of Journal AWWA (American Water Works Association) features a San Diego County Water Authority employee’s thoughts on a larger discussion about what the world of water could look like in 2050. In a piece titled “Addressing the Global Water Crisis With Membrane Technology”, Water Authority Principal Engineer Silvana Ghiu and her co-authors expanded on the vital importance of membrane technology for a hotter and dryer planet.

“The United Nations’ World Water Development Report 2023: Partnerships and Cooperation for Water estimates that the urban population facing water scarcity will increase from 933 million in 2016 to between 1.7 and 2.4 billion by 2050, representing one-third to one-half of the global urban population,” the article’s authors highlighted.

What can be done to fight against this global emergency?

The November edition of Journal AWWA

“After decades of advancements and innovation, membrane technology has evolved into an essential tool that can harness unconventional water sources to provide safe, sustainable drinking water.”

San Diego County residents don’t have to go far to see this technology in action. In fact, it’s being used right here in Carlsbad.

“In California, drought is intrinsic to the natural climate, and the need for local, reliable water supplies led to the 2015 construction of the Claude ‘Bud’ Lewis Carlsbad Desalination Plant, the largest desalination plant in the Western Hemisphere, with a capacity of 50 mgd (million gallons per day).”

From desalination along the coast to using membrane technology to treat brackish water in the interior, along with future advancements that could create even more opportunities for reliability, this technology is clearly here to stay.

“Membrane technology could be present in some capacity in nearly every new water plant built by the middle of this century,” writes Ghiu and her co-authors. In San Diego that future is already here as the Water Authority continues to build a reliable regional water supply for a changing climate. To read more, click here.

Utility Patent-Pipeline Inspection Tool-

Water Authority Wins Golden Watchdog Award

October 21, 2024/in Achievements, Features, WNN /by Jordan Beane

The San Diego County Water Authority won a Golden Watchdog Award at this year’s Golden Watchdog & Fleece Awards hosted by the San Diego County Taxpayers Association on Oct. 18. The Water Authority was recognized for its deployment of “Scanny,” a high-tech surveillance device designed to safely and efficiently monitor the agency’s large-diameter pipelines that provide water to the San Diego region.

The inspection tool uses commercially available lightweight adventure cameras and lights that are arranged in a unique way on a chassis that moves through pipelines that are 4 to 9 feet in diameter. Photo: San Diego County Water Authority

A special congratulations to the Water Authority’s Operations and Maintenance team and in particular Asset Management Manager Martin Coghill, who designed and patented “Scanny” on behalf of the Water Authority.

Proactive maintenance and asset management practices allow water agencies to extend the lifespan of their pipeline assets by more than 50%. With 308 miles of transmission pipelines, 100 flow control facilities and more than 1,400 pipeline-related structures, the Water Authority is constantly assessing and inspecting critical infrastructure across the county. This not only ensures that the Water Authority can stay ahead of potential emergencies but also reduce the need for replacing infrastructure.

Inspections involve crews entering the drained pipelines and evaluating around 30 miles each year. The pipelines traverse the hilly terrain of San Diego County, and some sections are so steep that they require the use of specialized rope and rigging support teams. That’s where “Scanny” comes in. Using an array of cameras to provide high-definition video surveillance of the interior of the pipeline, invented by Water Authority staff, provides the ability to inspect these pipes without requiring specialists.

The benefit of this technology goes beyond proactive maintenance. When compared to the cost of hiring specialized rope and rigging teams, “Scanny” paid for itself in just two deployments. “Scanny” can also be deployed multiple times each year during the inspection season.

Asset management at the Water Authority is more than just using new technology, it’s a strategic investment. In round numbers, the cost to replace 1 mile of large-diameter pipeline can be around $10 million. The cost to assess and maintain the same mile of pipeline may be around $100,000 every 10 years.
