Water Authority Earns National Conservation Innovation Award

/in , /by

The San Diego County Water Authority was recognized with a national award from the Alliance for Water Efficiency for programs that help county residents and businesses conserve water. The Water Authority earned the 2023 Utility Innovation Award for developing and deploying of one of the first and most comprehensive multi-benefit water-use efficiency incentive programs in the nation, in partnership with the County of San Diego.

The partnership combines the strength of the region’s wholesale water supplier with the county’s stormwater department, which together have co-funded incentive and educational programs that produce both water supply and water quality benefits.

Water Authority recognized with national award for regional partnership

The partnership also includes a technical assistance program, the Landscape Optimization Service, which helps large landscape owners replace turf grass with sustainable landscaping. In addition, the Water Authority launched the “Multi-Benefit Stacked Incentives Learning Network” to bring together its 24 member agencies and 21 stormwater agencies to foster investments with multiple benefits.

The Alliance for Water Efficiency is a national nonprofit organization headquartered in Chicago dedicated to the efficient and sustainable use of water. The organization advocates for water-efficient products and programs and provides information and assistance on water conservation efforts.

Innovative programs

“The Alliance for Water Efficiency was thrilled to present the 2023 Utility Innovation Award to the San Diego County Water Authority,” said AWE President and CEO Ron Burke. “The Water Authority … has been a longtime, trusted partner in this work. Our staff was excited to present this award in recognition of their innovative programs to provide services to their customers that conserve water and advance water efficiency throughout San Diego County.”

In addition to its partnership with the county, the Water Authority regularly works with other agencies to promote water efficiency as a way of life. Since 2021, the Water Authority has partnered with SDG&E to install water-efficient toilets along with energy saving devices for income qualified residents.

“Helping water users improve efficiency reduces the need for imported supplies as we embrace sustainable practices,” said Mel Katz, chair of the Water Authority’s Board. “This award highlights successful efforts by the Water Authority and its partners to ensure San Diego County can sustain our safe and reliable water resources for the long-term.”

Earlier this year, the Water Authority secured $3 million from DWR’s Urban Community Drought Relief Grant and $250,000 from the Proposition 1, Round 2 IRWM Grant to expand the program, bolstering the agency’s long-running efforts to enhance water affordability. The program is also funded through a partnership between the Water Authority and the Metropolitan Water District of Southern California.

Dan Denham Appointed San Diego County Water Authority General Manager

/in , /by

The San Diego County Water Authority Board of Directors August 24 voted unanimously to appoint Dan Denham as general manager. The appointment follows the June retirement of former General Manager Sandra L. Kerl.

Denham has served in several leadership capacities with the Water Authority for the past 17 years, including his most recent post as deputy general manager. In that role, he oversaw the MWD and Colorado River programs, along with the Engineering, Water Resources, and Operations & Maintenance departments. Denham also continues to oversee the implementation of long-term agricultural-to-urban conserved water transfers that are among the largest in the United States. As a commissioner on the Quantification Settlement Agreement Joint Powers Authority, he leads the Water Authority’s fulfillment of environmental mitigation obligations and legislative advocacy efforts at the Salton Sea.

Dan Denham: “Depth of experience”

“We are fortunate to have Dan’s knowledge of the San Diego County Water Authority and his depth of experience managing multiple programs, including the landmark agreements that have ensured a safe and reliable water supply for San Diego County,” said Mel Katz, chair of the Water Authority Board. “We look forward to working closely with Dan to ensure the Water Authority’s continued success serving our vibrant region.”

As general manager, Denham’s priorities include continuing to enhance relations with the Water Authority’s member agencies, minimizing rate increases, concluding the long-running litigation with the Metropolitan Water District of Southern California, and ensuring long-term water supplies for the semi-arid San Diego region.

“Position of strength”

“I’m thankful for the opportunity to lead this agency and build on the many achievements of my predecessors, my colleagues, and generations of leaders on our Board,” said Denham. “It’s clear there are few easy answers to some of our generational challenges like water reliability – but there never has been. Thankfully, San Diego County can work from a position of strength based on our investments in supplies and conservation over the past 30 years.”

Before joining the Water Authority in 2006, Denham served in various capacities at the City of San Diego’s Metropolitan Wastewater Department, Financial Management Department and Mayor’s Office.

Vista Irrigation District Celebrates 100 Years of Service

/in , /by

The Vista Irrigation District, one of the San Diego County Water Authority’s 24 member agencies, is celebrating its 100th anniversary.

In the 1920s, citrus and avocado farming in the Vista area increased so quickly that the growing region faced the real danger of running out of water. Completing the Henshaw Dam in 1923 made it possible for the Vista community to receive a reliable water source instead of relying on well water.

The arrival of the new water source sparked discussion about forming a water district to secure additional imported water to make continued growth possible. On August 28, 1923, voters approved the formation of the Vista Irrigation District (VID) in a landslide: 104 votes to four votes in a 100% voter turnout.

337 customers then, 134,000 customers now

In its first year, VID served 337 customers. Today, VID serves water to more than 134,000 customers in a diversified community and robust economy and is celebrating its 100th anniversary on August 28, 2023.

“Vista Irrigation District is proud of its accomplishments over the last century and looks forward to providing reliable water service to the residents and businesses it serves for years to come,” said Board President Jo MacKenzie.

Water builds new potential in Vista

The Vista community celebrated the arrival of the first water from Lake Henshaw on February 27, 1926. Following the arrival of water, crops of all kinds were planted in increasing numbers. The Vista area became known as the “Avocado Capital of the World,” with six avocado packing houses in the area.

In June 1946, after several years of negotiations, Vista Irrigation District purchased the San Diego County Water Company. Included in the purchase was the 43,000-acre Warner Ranch, a former Spanish Land Grant, which includes Henshaw Dam and Lake Henshaw. The deal was driven by the economic motivation to find another, less costly source of water for VID’s customers.

Drought conditions and population growth continued to press VID to seek additional sources of water. On February 16, 1954, the Vista Irrigation District became a member of the San Diego County Water Authority. It allowed VID to bring in water imported from the Colorado River and Northern California.

One year later, in 1955, Vista’s first suburban-style housing arrived in what had been an agricultural community. The Vista area began experiencing a decline in its avocado producing and packing due primarily to the industry’s economic decline and drought, which would continue into the 1960s. Many avocado groves were split into smaller parcels and sold to housing developers. The land was more valuable for homes.

A century of success

The people’s vote in 1923 revolutionized the small rural settlement held back by a lack of water. Over the years, Vista transformed itself from its agricultural origins to a thriving community with a diversified economic base and a revitalized downtown.

Vista Irrigation District has demonstrated its ability to adapt to these ever-changing landscapes over time and looks forward to many more successful years of service to the community. Through a century of service and stewardship, the Vista Irrigation District can take credit for its solid track record over the last century to continue many more successful years of service to the community.

Mountains Inspire Winners of San Dieguito Water District 2023 Landscape Contest

/in , /by

Large trees were the driving force that led Encinitas homeowners to remove grass and create a vibrant, low-water use landscape. The waterwise transformation won the San Dieguito Water District 2023 Landscape Makeover Contest.

Rick and Melanie Cullen had a yard with grass with large shade trees. But the roots of their three large Liquidambar trees were damaging the driveway and the grass, which motivated the couple to remake their landscape.

“San Dieguito Water District is proud to recognize customers like the Cullens, who create beautiful and resilient landscapes while making efficient use of their water,” said Isam Hireish, general manager of San Dieguito Water District.

The Cullens wanted to plant a drought-tolerant, water-wise yard that would be easy to maintain, beautiful, and hold up to their frequent travel schedule.

“My inspiration was to create a water wise, drought-tolerant front yard that also provides us a beautiful yard as if we were in the mountains,” said Melanie Cullen. It started with taking existing small landscape rocks and repurposing them into a natural dry streambed feature.

Plants were selected that would thrive in the coastal San Diego County environment. The invasive Liquidambar trees were replaced by Blue Ice Cypress, Forest Pansy Red Bud, and dwarf Deodar Cedar trees. Colorful drought-tolerant flowering shrubs and perennials including Coastal Woolybush, salvias, echinaceas, Texas primrose, heronsbill, columbine, Grevillea ‘Mt. Tamboritha’ and ‘Sour Grapes’ Penstemon provide habitat for pollinators.

Fragrant ground cover

Grasses including Pennisetum ‘Fireworks’ and Acorus ‘Variegated Sweetflag’ add to the plant palette. Creeping Thyme and trailing Rosemary are used as colorful, fragrant ground cover.

A highlight: one dozen Azaleas create a woodland flower look. Cullen says they bloom when other plants aren’t flowering.

“One might think they are water hogs, but they get the same water as everything else and bloom quite a bit throughout the year,” said Cullen. “It was a matter of choosing the right type of Azalea (Red Bird and Alaska White).”

Drip irrigation system saves water

The Cullens used a drip irrigation system that encircles each plant individually to direct water to the specific plant. They already had a smart irrigation controller which is still in use. A remote moisture sensor was added allowing the homeowners to monitor the ground moisture at the plants and then adjust watering for the yard.

Three to four inches of bark mulch helps retain irrigation, which has worked “extremely well.”

Tapping rain

Melanie Cullen says the irrigation was turned off completely from January through May due to generous rainfall. “Presently, we only need to water once every one to two weeks for 20 minutes,” she said.

“I join our Board of Directors in recognizing the leadership of the Cullens and commend them for taking proactive steps to improve our community’s resilience to a changing climate,” said Isam Hireish, General Manager of San Dieguito Water District. “I encourage all customers to utilize water more efficiently and take advantage of the various water-saving incentives we offer.”

In the months since the landscape makeover, the Cullens report all their original goals were met. “We love sitting in our front now and watching the many hummingbirds that also love our yard,” said Melanie Cullen.

Vallecitos Water District 2023 Landscape Makeover Winners Find Inspiration

/in , /by

Three resourceful homeowners took advantage of free resources, including design and plant selection advice, to create beautiful drought-tolerant landscapes. Their projects were named winners of the 2023 Vallecitos Water District Landscape Makeover Contest.

Video features the three winning projects

Dean Williams: Drab To Delightful

Carlsbad homeowner Dean Williams and his wife didn’t like their existing landscaping.

“It wasn’t a garden, it was a yard,” recalls Williams.

In 2020, Williams found resources on the Vallecitos Water District website for saving water by redesigning your landscaping. The results won first place in the 2023 landscape makeover contest.

“There are so many resources. The first step was to take some landscape classes offered through the San Diego County Water Authority, find out the process and what I needed to do,” said Williams.

After removing existing turf using the sheet mulching method to create healthy soil, he planned a colorful plant palette to replace his grass.

Williams said the benefit of installing drip irrigation and a smart controller was significant water and cost savings.

“We’ve noticed over that our water use and bills have gone slowly down,” he said.

Lessons learned

Williams said the “do it yourself” project offered many lessons learned, including watering too often.

“Drought-tolerant plants don’t do well in wet soil,” said Williams.

Williams encourages other homeowners to tap into all the available resources through the Vallecitos Water District, Water Authority, City of Carlsbad, and others for advice and possible rebates to offset their investment.

“It just pays in more ways than one to change your landscape. “I want to thank Vallecitos Water District for selecting us so we can showcase our landscape transformation,” said Williams.

Donald De Tar learned about the annual Landscape Makeover Contest through the Palomar Cactus and Succulent Society. “So, we decided on a lark to enter,” said De Tar.

His Woodlawn Park area home in San Marcos is dedicated to succulents, cactus, and drought-tolerant plants.

De Tar says it not only saves water but it also saves time spent mowing, fertilizing, and trimming grass. It’s also a lot of fun.

De Tar is proud of the budget-friendly approach to his landscaping.

“I did it on a very inexpensive budget,” said De Tar. “It doesn’t have to be super expensive, especially if you join an organization like the Palomar Cactus and Succulent Society. It can be almost free, especially if you’re doing the work yourself.”

De Tar learned about rebate programs through the Vallecitos Water District, and he successfully applied for rebates to offset costs. “Over time, we did the whole yard, and the backyards and side yards have been transformed.”

I’m very appreciative of the Vallecitos contest,” said De Tar. “I like the fact that Vallecitos is involved in the community and promotes these kinds of contests.”

Mily Le Wins Third Place

Third place went to longtime San Marcos homeowner Mily Le. She learned about the annual landscape contest through the Vallecitos Water District’s customer newsletter, “Between The Pipes.”

Le visited the lawn replacement program website and learned how to remove her regional grass safely and effectively. She got her design laid out and purchased plants from her local nursery.

As a result, Le says she saves about 30% of her water consumption after replacing her lawn. She says she learned from a neighbor’s experience about researching the eventual size of plants before planting them.

“(My neighbor) did not look it up,” she said. “She had to demolish the front yard, so I took that lesson.”

Le suggests lots of advance planning with your layout. “I’m glad I did it. I think it’s a successful project,” said Le.

The slope of a 1920s La Mesa home went from a drab lawn to lush floral color with climate-appropriate plants, winning recognition from the Helix Water District as the runner-up in its 2023 WaterSmart Landscape Contest.

The contest promotes beautiful, water-efficient landscapes and rewards people for their inspiring gardens. Joanna and Larry Henning created the country garden with climate-appropriate plants.

The Hennings bought the property in La Mesa‘s historic downtown area in 2017. Its landscape was covered in weeds and poorly maintained trees. The couple wanted a new landscape that would fill in the expansive slope and be water efficient while staying true to the character of their home.

Succulent cuttings

Planting an area this large with new plants can be expensive. But the couple were creative and resourceful, sourcing their plants for the new landscape design. Larry Henning used succulent cuttings from friends and family to plant most of their new landscape.

They supplemented the landscape with carefully chosen specimen plants, including protea, sages, and plumeria. These choices create the landscape’s variety of interesting shapes and colors. Five years after starting the project, even the slowest growing plants are fully grown and have transformed the landscape.

Irrigation efficiency

The landscape uses water efficiently to provide enough water for the plants to flourish without waste. Watering schedules are controlled using a smart weather-based irrigation controller. It automatically adjusts for rain and weather changes. Plants receive water from inline drip irrigation with pressure-compensating drip emitters.

Pressure compensation is essential for sloped landscapes because it maintains even watering rates all along the slope and prevents overwatering areas at the bottom of the landscape, where pressure is higher. Mulch covers the drip system, which protects the soil and slows evaporation.

Colorful addition to the La Mesa neighborhood

The landscape delivers ample curb appeal. From the street, trees frame the landscape, filled with shades of green and pops of color. Viewers can also see agave, cacti, and dozens of other succulents. Many display long cones of flowers. From the front patios, the garden provides a tranquil space for the family to enjoy.

District officials selected the landscape for special runner-up recognition due to its impressive transformation and efficient use of color and irrigation.

Helix Water District holds its landscape makeover contest annually. Entries are accepted starting every February through mid-May. For entry information, go to landscapecontest.com.

Santee Garden Oasis Wins 2023 Padre Dam Municipal Water District Landscape Contest

Santee homeowners Edie and Tate Thomas created a beautiful landscape with California native plants to save water, beautify their home, and support the region’s wildlife. Their effort won the 2023 Padre Dam Municipal Water District landscape makeover contest.

Preserving rainfall by design

In 2018, the couple began working on their makeover project. Edie Thomas is an architect, and Tate Thomas is a contractor. They took advantage of their building and design skills by creating a topography to capture and preserve the rainwater falling on their yard.

Their landscape is irrigated through underground rock ravines that collect rainwater in a rock-lined underground cistern reservoir which flows water to plants through gravity. They also buried large unglazed clay pots in their yard called ollas, which have above-ground access points to refill them with water. Plants wrap their roots around the porous ollas, which seep water out as needed, watering the plants with minimal water loss.

Edit Thomas advises other homeowners to do the same with their landscape topography.

“I always recommend people visualize a single drop of rainwater falling at the highest point of your landscape,” she said. “Watch where gravity takes that raindrop and plan your landscape around that flow.”

The pair also use drip irrigation about once a month along with occasional hand watering during extended dry periods.

Colorful variety of native plants featured

Long nature walks and information from the California Native Plant Society inspired the Thomas’s to use native plants for most of their landscape, mixing colors and texture to be visually appealing. They have been richly rewarded with an ecosystem of butterflies, caterpillars, bees, birds, and bunnies. They describe their design concept as “playful chaos.”

Community space

The sidewalk in front of the garden is designed to be a community space for those walking by. The large California Coastal Live Oak provides shade to the retaining wall, designed as a place to sit and rest. Visitors can browse through books from the couple’s Little Free Library. Water-efficient herbs growing in the planter boxes under the tree are offered to those who pass by.

Edie and Tate Thomas spend most evenings on their patio, enjoying the space and watching their ecosystem thrive. They look forward to watching the plants grow and mature in the coming years and even decades.

“It’s so rewarding to see people come by and rest in the shade or take some rosemary for their dinner,” said Edie Thomas. “I love that we get to give a small square of land back to nature and that our neighbors enjoy it as much as we do.”

San Marcos Unified School District Benefits From Free Water Use Survey

/in , /by

Free water use surveys offered through the Metropolitan Water District of Southern California provide both residential and commercial customers with recommendations to improve landscape and indoor water use efficiency. The surveys are available throughout Southern California, including San Diego County.

The San Marcos Unified School District took advantage of the opportunity for water use surveys at 17 of the district’s school sites. It is among the largest single regional customer survey to date.

Austin Black, water conservation specialist for WaterWise Consulting, oversees the audit project.

“We are auditing the irrigation system of all of the schools with more than one acre of landscape area [for this project],” said Austin. “The survey tests all the different irrigation zones, looking at the type of landscape and plant material, and weather factors. We take all that data and calculate potential water savings based on our recommendations.”

Recommendations may include converting to drip irrigation, installing smart controllers, and replacing grass with a WaterWise landscape with a more efficient watering system.

Surveyors also adjust existing sprinklers for maximum efficiency and compile a list of repairs and upgrades to improve water use efficiency.

“In our effort to be good stewards of all resources used by the district, the decision to participate was an easy one,” said Ted Norman, SMUSD executive director of maintenance and operations. “We will review all our options and implement as many of the recommendations as we can. It’s a win for everyone.”

Simple improvements add up to significant savings

In one example, the audit report provided to the district for the San Marcos Elementary School estimates that implementing the recommended water-saving measures can reduce landscape water use by approximately 252,000 gallons. Project cost savings are $1,363 annually. If similar savings are achieved at 17 schools, this reflects significant net savings to taxpayers.

“We will submit the reports, and the district can make the changes as they wish,” said Black. “The goal is to create water savings for the entire district and the [water] agency as well.”

MWD can assign a consultant to work with SMUSD and other customers after the audit is completed to help prioritize changes recommended in the survey. The consultant services are free.

Homeowners can also take advantage of free surveys. Residential surveys look at both indoor and outdoor home water use.

“It’s a comprehensive survey checking for leaks and ways we can make the household more efficient,” said Black.

Along with irrigation improvements, the residential audit reviews the replacement of inefficient plumbing fixtures and other simple adjustments.

A certified landscape irrigation auditor will schedule a survey and provide written recommendations for qualifying properties. Participants will receive a written report that includes the following:

  • Data collected during the survey.
  • Recommendations for improving the site’s irrigation efficiency including system repairs, equipment updates, and irrigation scheduling.
  • Information about available financial incentives to help with the cost of recommended improvements.

Surveys are scheduled on a first-come, first-served basis. Applying does not guarantee a survey will be provided. Properties may only receive one survey for the life of the program. After filling out an online application the next step is scheduling a visit from a certified landscape auditor.

San Diego County residents can also take advantage of savings with rebates on a variety of water-saving technologies such as high-efficiency clothes washers and toilets, rain barrels and irrigation nozzles.
