Make a Map of Your Irrigation System

It’s easy (and fun) to produce a landscaping plan showing where every shrub and flower is placed on site. Drawing what you can see is relatively easy.

But what about the irrigation system underneath your landscaping? Do you know the location of your water mainline, irrigation system clocks, valves and sprinkler heads?

Understanding the layout of your irrigation system is important so you can accurately locate components for seamless repair. If you plan on adding to or upgrading the system, you’ll want an irrigation map to guide construction.

Steps to making your irrigation map

First, locate all of the sprinkler heads on your property and mark their location on a copy of your landscaping site plan. Also mark the location of the following elements:

• Water meter or irrigation sub meter, and where the water comes from the street onto your property (the main line)
• Irrigation controller
• Shut off valve for turning off the irrigation system
• Pressure regulator – this may be for the irrigation system separate from the house. If your irrigation comes from a pipe that first serves the house, it may be located before it enters the house.
• Irrigation valves
• Hose bibs
• Backflow preventer – if you don’t have one, your sprinkler valves probably do, so don’t worry

Observe and color code which sprinklers go on at the same time when a valve is turned on.

Adapting your existing irrigation system to a new efficient system

Use your irrigation map to determine which parts will work with a new, more efficient system without abandoning everything and starting from scratch. If you’re removing or renovating most of your landscaping, you might need to alter the irrigation. In that case, starting from scratch can end up being the most cost and time efficient alternative.

Water Authority Invites Gov. Newsom to Tour Facilities, Praises Portfolio Approach to Water Security

The San Diego County Water Authority today praised Gov. Gavin Newsom for taking a proactive, far-sighted approach to water supply planning for California, and pledged to help the governor advance his portfolio strategy for water security in the face of a changing climate.

In a letter to Newsom, Water Authority Board Chair Jim Madaffer thanked the governor for the “wisdom and leadership” shown last week with the issuance of Executive Order N-10-19 and invited the governor to tour San Diego County’s cutting-edge water facilities.

Newsom’s order directed his administration to “identify and assess a suite of complementary actions to ensure safe and resilient water supplies, flood protection and healthy waterways for the state’s communities, economy and environment.” Newsom then directed state agencies to scrap Brown Administration plans for a $18 billion two-tunnel system for moving water through the Sacramento-San Joaquin Bay-Delta in favor of a one-tunnel system.

“We congratulate you on Executive Order N-10-19 and stand ready to support you and work with other stakeholders to ensure its success,” Madaffer wrote to Newsom. “If state and federal dollars are prioritized to support local, integrated planning solutions, we will realize the State’s 2009 promise to reduce demand on the Bay-Delta.”

Portfolio Planning For Water Security

The Water Authority has a long history of both portfolio planning for the region’s water security and supporting a portfolio approach to address mounting environmental and water supply challenges in the Bay-Delta, the hub of the State Water Project.

“Almost two decades ago, the Water Authority’s Board of Directors chose to take affirmative steps to change what had been an ‘end-of-the-pipeline’ mentality, when our agency relied greatly on water imported from the Bay-Delta,” Madaffer said. “In other words, we embraced then the intent of Executive Order N-10-19, and believe our experience is proof that it can be done.”

In 2013, the Water Authority joined several Southern and Northern California water districts, Natural Resources Defense Council, and other conservation groups in proposing a Portfolio Alternative for the Bay-Delta. That proposal included a single tunnel, increasing water storage south of the Bay-Delta, and significant investments in local and regional water supplies.

That approach didn’t gain enough support in the Brown administration, but it aligns closely with Gov. Newsom’s executive order.

Strategic partnerships

The portfolio approach also aligns with what history has shown to be a highly successful strategy in San Diego County, which relied almost entirely on water supplies controlled by external interests in 1991.

“After suffering the devastating impacts of drought and water shortages that year, our community got to work, determined to gain local control over the cost and reliability of our water,” Madaffer said. “Since then, the Water Authority and its member agencies have invested over $2 billion in local projects.”

Those investments include:

  • The nation’s largest agricultural water conservation and transfer agreement with the Imperial Irrigation District
  • The first new dam in the county in more than 50 years at Olivenhain Reservoir
  • The nation’s largest seawater desalination plant, producing up to 56,000 acre-feet of water annually
  • The raising of San Vicente Dam, more than doubling its capacity
  • Water-use efficiency programs that have helped reduce per capita potable water use by more than 40 percent in San Diego County

“Every dollar of investment the Water Authority has made represents a commensurate reduction of take on the Bay-Delta,” said Madaffer’s letter.

He noted that the Water Authority and its member agencies are still at work, with more local projects on the drawing board, including a Pure Water potable reuse program being developed by the City of San Diego and the East County Advanced Water Purification Project.

“We are also continuing to plan for the future, with an upcoming study that will explore water, conveyance, storage, treatment and energy opportunities with strategic partners in Imperial Valley, Mexico and across the Southwest,” Madaffer said. “This initiative is the next generation of the Water Authority’s evolution, and the ‘poster child’ for your Portfolio Alternative.”

The Water Authority is looking at new integrated solutions such as a storage account in Lake Mead that would help raise water levels in the drought-stressed reservoir and avoid formal shortage conditions that could hamper water deliveries across the Southwest. The Water Authority also is supporting a Salton Sea action plan that will protect both the environment and public health; binational opportunities with Mexico; and clean energy generation.

San Diego County Students Shape the Future of Water

On April 25, the San Diego County Water Authority Board of Directors honored the latest group of water-related award winners from the Greater San Diego Science and Engineering Fair as part of the agency’s effort to inspire young people to pursue water industry careers.

This year’s middle school and high school science and engineering projects displayed a wide range of innovative ways to solve a variety of water issues people face today.

In the senior division, Alfred and Audrey Vargas won the first place award with the design of a new device to treat wastewater and generate electricity simultaneously using hydrogen fuel cell technology. The siblings, who attend Sweetwater High School, also won their division last year and continue their work in designing devices and systems that can potentially be used in developing countries where resources are scarce.

Alfred and Audrey have been competing in science fairs since they were in middle school and have always been inspired by a drive to solve world water issues in affordable ways.

“As we’re looking for the next generation of water industry professionals, events like the Greater San Diego Science and Engineering Fair are the perfect opportunity to connect with and support students who are already interested in relevant water issues,” said Water Authority principal public affairs representative Risa Baron, who helped select the winners. “These young thinkers and inventors can make huge strides in solving future water challenges around the world.”

Finding inspiration in the natural world

Cambridge School student Emily Tianshi won the second place award in the senior division. She looked beyond the ocean views at Torrey Pines State Park to see the intelligent ways that nature sustains itself and how those can be imitated.

Emily spent the past three years perfecting a design for a device that can capture moisture from the air like Torrey Pine needles do. Using 3-D printing technology to bring her project to life, Emily demonstrated that the naturally occurring ridges of Torrey Pine needles efficiently collect water, and she designed a model of a device that would mimic the shape of the needles.

In the junior division, Brendan Cordaro and Max Shaffer from Saint John School in Encinitas teamed up to win first place with “The Water Maker,” a homemade device that transformed a miniature refrigerator into a means of collecting water from the air.

Oliver Trojanowski, who is also a middle school student at the Saint John School, won the second place award in the junior division. Oliver surveyed several sites in the region to test for water quality and determine toxicity levels in stormwater runoff.

Matthew Angulo from the Corfman School in El Centro earned the third place award in the junior division. He travelled over 100 miles to showcase his results from several tests of water samples from the Colorado River.

Welcoming the next generation of water professionals and leaders

More than 2,800 people across all levels of educational attainment work at the Water Authority and its 24 member agencies to provide safe and reliable water supplies to the region.

The Water Authority and its member agencies are committed to fostering the next generation of industry professionals and leaders. Engineers, system operators, maintenance technicians, customer service representatives and utility workers are just some of the many careers available in the water industry.

OPINION: San Diego Is Ready For Some Big Water Solutions

Back in the early 1990s — near the start of my career at San Diego City Hall — the San Diego County Water Authority launched a historic effort to sustain the region’s economy and quality of life by diversifying our water supplies so that we didn’t depend on one source for 95 percent of our water. That effort took many forms, many billions of dollars and more than two decades — but it paid off in spades. Even though we are at the literal end of the pipeline, today we have among the most diversified and secure water supply systems anywhere.

As More People Move To The Inland Empire, How Is There Going To Be Enough Water?

With all of the new housing going up and considering we’re in a drought area, how is local government going to provide enough water? Water scarcity is an issue people in Southern California think about a lot. California experienced one of the worst droughts in state history from 2011 to 2017. Governor Jerry Brown declared a drought State of Emergency in 2014, calling for statewide water conservation. By 2022, California residents will need to limit their indoor water use to 55 gallons of water per person a day. And by 2030, that number will drop to 50 gallons.
