Understanding Every Drop: How Flume & the Water Authority are Shaping the Future of Water Use

/in , /by

The San Diego County Water Authority is in the midst of its second year operating a cutting-edge program across the region to help residents and member agencies know — down to the gallon — how the region uses water. From the garden hose to the kitchen faucet, the toilet to the shower, getting a clear understanding of how residents use their water helps resource agencies make the best planning decisions for the future.

The program is a joint venture between the Water Authority and Flume, a California-based company, that collects anonymous data from regional residents and builds a robust understanding of where each drop goes. Flume’s flow sensors are simple to install and provide real-time data about household water use. That provides a big benefit to property owners who can monitor water use from their phones and receive alerts if a leak is detected.

In addition, the program has given the Water Authority a window into trends and datapoints from more than 4,300 Flume devices that would not have been available otherwise. This information allows the Water Authority to see how residents use water over time and how events such as droughts and storms impact regional water use.

The data is aggregated at the regional level from residents who voluntarily installed Flume devices on their water meters, through a grant-funded program managed by the Water Authority. In addition, some local water districts have promoted – or even paid for – the use of flow sensors to reduce leaks and improve water-use efficiency.

A data set showing the kind of information collected by Flume.

The data has provided a detailed look at regional water use in a way that has never been available before. From 2022 to 2025, the Flume devices showed decreasing water use, with households going from 380 gallons per day to 321. This data confirms the general trendlines about water conservation being a way of life across the region. Another trend highlighted by the data was that rain tends to have a greater effect on water use than heat, with storms pushing water use down more than heat increases it. In addition, the devices confirm that outdoor water use continues to outpace indoor water use, making up 63% of the region’s total residential water footprint.

Water Authority Board members aren’t just supporters of the program; some of them are also among the thousands of residents around the region who use Flume devices to understand their own water use. “You can’t manage water use when you don’t know how much you’re using,” Helix Water District Director Kathleen Coates Hedberg said during a recent Board meeting.

The Water Authority’s Water Resource Department will continue to monitor the regionally aggregated data to help agencies across San Diego County better understand where every drop is going, allowing for better water management decisions in the years to come.

Study Shows Carlsbad Desal Plant Offers Eco-Friendly Water

/in , , /by

The Claude “Bud” Lewis Carlsbad Desalination Plant offers an environmentally responsible water supply in an era of increasing water scarcity, according to results of a new scientific study being released next week at a statewide conference of desalination experts.

The report – the largest environmental assessment to date of the nation’s largest seawater desalination plant – also highlighted the comprehensive monitoring requirements in place for desalination plants in California to demonstrate how nearshore waters remain healthy.

“The most robust monitoring program of the area ever completed demonstrated the Carlsbad Desalination Plant is operating in compliance with all applicable regulations and permits in harmony with the coastal marine environment,” said the study, prepared by Miller Marine Science & Consulting, Inc. of Aliso Viejo.

To date, the desal plant has produced more than 124 billion gallons of high-quality drinking water for the San Diego region. The Miller Marine report was a requirement of the plant’s discharge permit and evaluates four years of extensive environmental monitoring conducted between 2019 – 2023.

100 Billion Gallons-Carlsbad Desalination Plant-Water Supply

“This study shows how seawater desalination can provide a new and reliable supply of water with minimal impacts to aquatic life. That’s a win for our region and the environment,” said Dan Denham, San Diego County Water Authority General Manager.

The Carlsbad Desalination Plant minimizes the San Diego region’s vulnerability to statewide drought conditions. It is part of a $1 billion project that includes the nation’s largest, most technologically advanced and energy-efficient seawater desalination plant, a 10-mile large-diameter pipeline, and improvements to Water Authority facilities for distributing desalinated seawater throughout San Diego County.

Next week, the Miller Marine report is being discussed during the annual conference of CalDesal, an industry association that brings together water leaders to discuss a range of issues related to seawater and groundwater desalination. For more about the conference, click here.

Among the study’s findings were:

  • The Carlsbad coastal marine environment continues to support its full suite of beneficial uses.
  • The Carlsbad Desalination Plant’s discharge is not disturbing the receiving water quality or environment outside the brine mixing zone.
  • The Carlsbad Desalination Plant is not discharging toxic substances to the detriment of the environment. The plant’s operations result in an environmentally safe discharge to the marine environment in compliance with all regulations.

The desal plant provides several environmental benefits by offsetting carbon emissions, employing cutting-edge technology to reduce and recapture 46% of energy consumption during desalination, and restoring extensive coastal wetlands to benefit native fish, wildlife, and plant species within South San Diego Bay.

New California Law Bolsters Groundwater Recharge as Strategic Defense Against Climate Change

/in , /by /Water Education Foundation / Western Water Newsby Nick Cahill

A new but little-known change in California law designating aquifers as “natural infrastructure” promises to unleash a flood of public funding for projects that increase the state’s supply of groundwater.

The change is buried in a sweeping state budget-related law, enacted in July, that also makes it easier for property owners and water managers to divert floodwater for storage underground.

The obscure, seemingly inconsequential classification of aquifers could have a far-reaching effect in California where restoring depleted aquifers has become a strategic defense against climate change — an insurance against more frequent droughts and more variable precipitation. The state leans heavily on aquifers, drawing about 40% of its water supply from the ground during an average water year and up to 60% during dry years.

More than $1 billion in state funds could become available to a wide range of projects that replenish groundwater, including flood control improvements and wetlands restoration, according to the Planning and Conservation League and the conservation nonprofit River Partners, which pushed for the designation.

New law and potential funding source

A recent change in California law is expected to result in significantly more public funding for groundwater recharge like this state-run project, which diverted floodwater from the San Joaquin River to a Madera County ranch in winter 2023. Photo: California Department of Water Resources

“There’s no question this is a critical step,” said Judy Corbett, a board member of the league. “We’re not talking about [funding] one thing at a time anymore — flood control or recharge or improving wetlands — but now everything.”

The new law also positions local water managers and nonprofit groups to potentially tap Proposition 1 funds – a 2014 statewide bond that dedicated $7.5 billion for water projects – and a sweeping climate resilience bond that Gov. Gavin Newsom and lawmakers are planning for the 2024 statewide ballot.

In the world of environmental policymaking, “natural infrastructure” refers to natural landscape features that provide concrete benefits to the public and to wildlife. Wetlands and floodplains, for example, can slow and retain water to reduce flooding while filtering pollutants and providing habitat for fish and water birds.

Lush Landscape Recognized as Runner-Up in Helix Landscape Contest

/in , /by

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.

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.

Residential surveys find water, cost savings for homeowners

Historic La Mesa Home Wins Helix Water District’s 2023 Landscape Contest

/in , /by

A charming 1925 La Mesa home featuring a rich tapestry of thriving low-water use plants won the 2023 Helix Water District Landscape Makeover Contest.

Homeowner Joy Andrea, a retired schoolteacher and La Mesa resident for more than 50 years, created a landscape with a tremendous amount of curb appeal, reflecting the character of the home. Andrea’s design includes a balanced mix of shrubs, ground cover, potted plants, large stones, and decorative statues.

Andrea transformed the previous all-lawn landscape into a low-water-use front yard with a thriving fruit and vegetable garden in the back yard.

“When I first moved here, all this was grass that you would have to water with a hose, or it would go brown in the summer,” said Andrea. “The neighbors that used to live around me would have to be outside watering with a hose. Bless their hearts, I never wanted that. It is more rewarding for me to plant, prune and maintain this space than a flat lawn.”

Joy Andrea selected plants with a consistent grey-blue theme showing pops of color throughout her La Mesa home. Photo: Helix Water District

Andrea placed numerous wrought iron statues within the landscape, inspiring imagination and life from every angle. She also included a bottle brush tree and used larger shrubs bordering the landscape. Containers are filled with succulent groupings spilling out.

The landscape design shows how smaller spaces commonly found in front of most residential homes can feel bigger by creating points of interest and using a variety of plants and trees to add color and character.

Design advice for a landscape you love

She has some advice for others wanting to makeover their landscapes.

“Pick hardy drought-resistant plants that you love and enjoy seeing,” she said. “Remember to keep your small plants in the front and have your taller plants toward the back and if you don’t like what you have, don’t be afraid to take it out, replant it or get something else.”

The irrigation system uses efficient drip emitters for the larger plants and tall pop-up sprays for the groundcover. Andrea enjoys tending to her potted plants by hand-watering them.

“Water is our single most important commodity on the planet,” said Andrea. “We must all use it carefully and not just in our yards and landscapes, but with everything we do.”

Annual competition invites residents to share their projects

Smart Irrigation Month Highlights Outdoor Water Saving Tips

/in , /by

Water agencies in San Diego County are sharing outdoor water-efficiency tips during “Smart Irrigation Month.”

July was chosen as Smart Irrigation Month in 2005 since its traditionally the month of peak demand for outdoor water use in the county. Landscape irrigation consumes 50% of the typical California home’s monthly water use.

Each year during Smart Irrigation Month, the Irrigation Association highlights the benefits of efficient irrigation and innovations promoting the wise and efficient use of water through this month-long initiative each July.  Irrigation technology innovation updates and efficient irrigation techniques help preserve our water supply.

Smart irrigation

As wireless technology has improved, it has been applied to outdoor systems including irrigation. With a smart irrigation system, homeowners can control water use through smartphone apps and programmable wireless controllers. Water consumption can be monitored to quickly find and correct leaks and maximize water application.

Adopt ‘cycle and soak’ irrigation method to maximize water use

The greatest waste of water in landscape irrigation comes from watering too much, too fast. Instead of watering for 15 consecutive minutes, run sprinklers in five-minute sessions with time in between to allow water to soak into the soil and minimize runoff.

This Vallecitos Water District video illustrates how the “cycle and soak” irrigation method works.

“July is our industry’s opportunity to share its amazing stories about contributing to a sustainable world,” said Irrigation Association CEO Natasha Rankin, MBA, CAE. “By promoting smart irrigation, our industry’s experienced and committed professionals work every day to protect our world’s valuable natural resources while supporting food production and creating landscapes that enhance the quality of life in our communities.”

July is an ideal month to perform a check on current irrigation systems and determine whether any practices can be improved to save water.

The San Diego County Water Authority offers these tips:

  • Select sprinkler heads and nozzles that apply water uniformly to the target area.
  • Inspect your sprinkler heads regularly to make sure they are not obstructed or watering onto the pavement or other hardscapes.
  • Upgrade to a smart controller. Weather and soil moisture-based controllers can automatically adjust your watering schedule based on the conditions at your location.
  • Use drip or low-pressure, low-volume irrigation which applies water directly to the base or roots of plants.
  • If water is applied too quickly, it can run off into the street or sidewalk. Smart irrigation regulates water pressure, ensuring water has a chance to soak into the ground.
  • Less is more when watering turf. Water long enough to soak down to the root zone, then don’t water again until the soil is completely dry. If the grass springs back when you step on it, it has enough water.
  • A rain shut-off device is an inexpensive gadget to add to your sprinkler system.
  • Improve efficiency by watering at the coolest time of day. When it’s hot or windy, more than a third of the water can be lost to evaporation.
