Fall Back and Adjust Irrigation Systems to Save Water

/in , /by

The end of daylight saving time is a reminder to residents to assess their outdoor watering needs and adjust their irrigation systems to reduce water waste – an especially important step after more than two years of statewide drought. Plants simply don’t need as much water during cooler months, and they typically don’t need irrigation at all after heavy rains.

“This is a great time to make sure irrigation systems are working properly and delivering the right amount of water,” said Jeff Stephenson, a water resources manager for the San Diego County Water Authority. “After two years of drought, using water efficiently and eliminating water-wasting practices is a critical part of preserving more of our precious supply.”

Adjust irrigation systems

Outdoor watering accounts for more than half of a typical household’s water use in California. Making seasonal adjustments to irrigation controllers can help reduce water waste and lead to healthier landscapes. Water-saving practices include turning off irrigation systems when rainstorms are predicted and leaving them off for at least a week after significant rainfall.

Using water efficiently indoors and outdoors is easier than ever thanks to online resources offered by the Water Authority at www.watersmartsd.org. The site is filled with information about conservation incentives, and it includes tools and programs designed to make the most of the region’s most precious natural resource. Saving water is easier than many people realize. A few simple changes can make a big difference – especially outdoors.

The 2021 water year was the driest in California in more than a century, but San Diego County continues to have reliable water supplies due to long-term investments in water sources and infrastructure, coupled with extensive water conservation efforts. Per capita potable water use in the San Diego region has decreased by nearly 50% since 1990 as residents and businesses continue to adopt WaterSmart practices.

Nine-Thousand Trees For Salton Sea Wildlife Marsh Habitat

/in , /by

Nine-thousand trees, mostly willows, are being planted in the 1,000 acre Managed Marsh wildlife habitat in northern Imperial County.

The planting is part of  the final construction phase of the Managed Marsh, located off Highway 111 between the city of Calipatria and Niland.

Funded by the Quantification Settlement Agreement Joint Powers Authority (QSA JPA), the habitat, located close to the Salton Sea, is a key environmental mitigation project to serve the needs of wildlife that depend on area surface drains in the Imperial Valley. With the planting of the 9,000 trees now underway, the Managed Marsh will be completed by early 2022.

Formed under 2003 legislation to administer the funding of environmental mitigation requirements related to the QSA water transfers, the QSA JPA is comprised of the Imperial Irrigation District, San Diego County Water Authority, Coachella Valley Water District and California Department of Fish and Wildlife.

Salton Sea Restoration Projects

As part of the legislation (specifically Senate Bill (SB) 654), the three water agencies of the QSA JPA have a responsibility to fund environmental mitigation projects related to the QSA up to $133 million in 2003 dollars (or $288 million in nominal dollars). The state has the responsibility to cover mitigation costs that exceed the $133 million mark and to address the larger issue of restoration at the Salton Sea. However, the three water agencies also have paid a combined $30 million in 2003 dollars (or $67 million in nominal dollars) as seed money for restoration, which was provided to CDFW as part of the Salton Sea Restoration Fund.

Nine-Thousand Trees for Wildlife in Managed Marsh

The Managed Marsh, built by IID as the implementing arm of the QSA JPA, was funded as part of the $133 million covered by the three water agencies. The project has been constructed over three phases, each 300 acres of marsh, with phase one completed in 2009 in and phase two in 2014. Phase three, the final stage, began last year when as many as 6,000 trees were planted. In total, once the Managed Marsh is completed, the entire facility will consist of more than 17,000 trees as well as wetlands, providing a habitat for more than 60 species of birds and other wildlife.

Public Resource

For years, the Managed Marsh has been open to the public, providing a resource for bird-watching enthusiasts and trail hikers. The facility also is an educational resource for area schools that have used the facility for field trips.

Since the QSA JPA was formed, it has been actively implementing mitigation projects in line with the QSA’s environmental permits, with much of that effort focused on the Salton Sea. For the first 15 years, the QSA JPA funded a fallowing program in the Imperial Valley that provided about 800,000 acre-feet of water to the Salton Sea, both to maintain salinity levels and to give the state time to begin a restoration program. At the same time, the QSA JPA implemented additional projects, like the Managed Marsh, in its ongoing efforts to address environmental mitigation.

Along with working toward the completion of the Managed Marsh, since 2018, the QSA JPA has focused on providing more permanent on-the-ground projects at the Sea, meant to address air quality impacts, including completing nearly 3,000 acres of surfacing roughening projects, with another 7,000 acres in development, growing vegetation, and supporting the reclamation of exposed playa for agricultural development where possible.

The QSA JPA will also be funding a groundwater pilot project as a potential water source for habitat development at the Salton Sea. While separate from the state’s Salton Sea Management Program, these are projects that work hand in hand with restoration in a collaborative effort.

Water Shortage Contingency Plan-Drought-WSCP-Water Authority

Water Authority Activates Water Shortage Contingency Plan

/in , /by

The San Diego County Water Authority today activated Level 1 – Voluntary Conservation of its Water Shortage Contingency Plan in support of Gov. Gavin Newsom’s efforts to sustain California after two record-dry years. The agency’s 36-member Board of Directors voted unanimously to activate the regional drought response plan for the third time this century.

The San Diego region continues to have reliable water supplies due to decades of conservation efforts and ratepayer investments. However, Water Authority Board Chair Gary Croucher said San Diegans should increase their conservation efforts in the face of a potential third dry year across California.

“San Diegans have always stepped up when duty calls,” Croucher said. “Today, our 36-member Board sends a unified message encouraging residents to conserve water, avoid water waste, and take advantage of rebates to improve water-use efficiency indoors and outdoors.”

Drought emergency declaration

On Oct. 19, Gov. Newsom extended his drought emergency declaration to cover the entire state and asked the State Water Board to ban wasteful water practices such as using potable water for washing driveways and sidewalks. In addition, the governor directed water suppliers to implement Water Shortage Contingency Plans, which are responsive to local supply-demand conditions.

Water Shortage Contingency Plan

The Water Authority’s Water Shortage Contingency Plan, or WSCP, is designed for situations in which the agency’s supplies have been reduced. Previous versions of the plan have been activated twice before – once in 2007 and again in 2014. While the region isn’t currently facing supply reductions, Croucher said the Board’s action to go to Level 1 sends a signal that increased voluntary conservation efforts are necessary, and it gives local retail water agencies flexibility to address local conditions. While the Water Authority’s WSCP Level 1 calls for 10% voluntary water savings, the agency is supporting the governor’s call for a 15% reduction.

WSCP Level 1 – WaterSmartSD

At Level 1, the Water Authority will continue and enhance regional outreach and education to promote conservation. The agency offers numerous tools to make the most of every drop at www.watersmartsd.org. Resources include:

  • Water-use efficient landscape classes for residential and professional landscapers
  • Rebates for indoor and outdoor water saving devices
  • Rebates for turf replacement
  • Water-use checkups for homes and businesses that include water-saving recommendations

Water supply reliability

The Water Authority is also developing a program to increase installation of low-flow toilets in low-income communities, and it’s looking for opportunities to help the parts of the state that are suffering from extreme water shortages. The Water Authority has groundwater stored in the Central Valley that could be exchanged or sold, and the Water Authority is seeking partners who could benefit from increasing water production at the Claude “Bud” Lewis Carlsbad Desalination Plant.

The Water Authority’s supply reliability is due to multiple factors, including the nation’s largest ag-to-urban conservation project which helps sustain the region’s $253 billion economy and the quality of life for 3.3 million people. In addition, the Water Authority developed the nation’s largest seawater desalination plant in Carlsbad, which provides 10% of the region’s water supply. Long-term conservation upgrades have also played a critical tole: the region’s per capita water use is down nearly 50% since 1990. San Diego County’s diversified water resources reduce pressure on the State Water Project and make more water available to other areas of the state hit hardest by drought.

A Model for Dealing with Climate Change

/in , /by

I’m so gratified to report that due to your efforts, today’s New York Times features a lengthy story recognizing the benefits of the San Diego County water reliability strategy – an approach that aligns with Gov. Newsom’s Water Resilience Portfolio.

The article addresses our region’s role in the nation’s largest ag-to-urban water conservation project, along with the conservation ethic embraced by homes and businesses across the region, and current investments in potable water reuse, which is the next major source of supply for the region.

The Times cited the Public Policy Institute of California – a leading think tank – commending the San Diego region’s efforts. And the story said our collective “try-everything approach to getting water has emerged as a model for cities — including Denver and Albuquerque — where leaders are dealing with one of climate change’s most dire effects.” Also today, the Southern California News Group published an editorial that showcased local investments as a model.

While we celebrate these recognitions, we remain acutely aware of the severe and worsening drought conditions across the West – and how important it is for the San Diego County to continue being a leader in statewide drought defenses. That’s why our Board next week will consider activating our drought response plan. This action supports the governor’s request that local water suppliers implement plans responsive to local conditions, and his extension of the drought emergency declaration to San Diego County.

Water Authority Prepares to Activate Water Shortage Contingency Plan

/in , /by

The San Diego County Water Authority is preparing to activate Level 1 – Voluntary Conservation of its Water Shortage Contingency Plan in support of Gov. Gavin Newsom’s efforts to sustain California after two record-dry years. The agency’s 36-member Board of Directors will decide at its formal monthly meeting on Oct. 28 whether to activate the drought response plan, following today’s recommendation by staff.

While the San Diego region continues to have long-term water resilience and reliable water supplies due to decades of conservation efforts and ratepayer investments, Water Authority General Manager Sandra L. Kerl said it’s critical to advance statewide efforts to combat drought.

“This is an all-hands moment,” said Kerl. “We are fully supportive of the governor’s efforts and fully engaged in helping residents and businesses do their part each and every day.”

Activate Water Shortage Contingency Plan

On Tuesday Oct. 19, Gov. Newsom extended his drought emergency declaration to cover the entire state and asked the State Water Board to ban wasteful water practices such as using potable water for washing driveways and sidewalks. In addition, the governor directed water suppliers to implement Water Shortage Contingency Plans, which are responsive to local supply-demand conditions.

While the region isn’t currently facing supply reductions, Kerl said the recommendation to go to Level 1 sends a signal that voluntary conservation efforts are necessary, and it gives local retail water agencies flexibility to address local conditions.

In line with Gov. Newsom’s Water Resilience Portfolio, San Diego County’s diversified water resources reduce pressure on the State Water Project and make more water available to other areas of the state hit hardest by drought. The Water Authority helped enact the nation’s largest ag-to-urban conservation project to sustain the region’s $253 billion economy and the quality of life for 3.3 million people. In addition, the region’s per capita water use is down nearly 50% since 1990.

Take actions to prevent water waste

“While we are hopeful that a wet winter will take the edge off this current drought, we need to recognize that may not be the case,” Kerl said. “The entire American West is facing hot and dry conditions not seen in our lifetimes, and the realities of climate change mean we need to prepare for this as the new normal.

“We have resources to help as every resident and business owner takes this call seriously and looks for ways they can take meaningful actions to prevent water waste.”

At Level 1 of its Water Shortage Contingency Plan, the Water Authority will enhance regional outreach and education to promote conservation. The agency offers numerous tools to make the most of every drop at www.watersmartsd.org. Resources include:

  • Water-use efficient landscape classes for residential and professional landscapers

Boost Your Irrigation IQ

/in , /by

To support and protect your investment in waterwise landscaping, you need to have a strong irrigation IQ and understand the basics. You’ll be able to best maintain and maximize your system’s efficiency, which is vitally important during times of drought in the San Diego region.

Conventional irrigation systems can be inefficient

Well-designed and operated systems can reliably deliver the necessary water to sustain your landscaping without waste or excess. Poorly performing systems can suffer due to bad design, inadequate maintenance, and improper management.

A shutoff valve (ball valve) can be manually operated to cut off the water supply in the event of a leak, a malfunction, or a major repair.

The anti-siphon valve, when activated by an irrigation controller, delivers water through a PVC pipe lateral irrigation line, ultimately reaching the sprinkler head, which applies the water to your landscaping.

Intelligent irrigation systems operate efficiently

Efficient irrigation components are designed to operate at lower pressure levels, as specified by each product manufacturer. Devices are more likely to fail under excess pressure, and damage can occur.

A pressure regulator will eliminate excess pressure.

A submeter can be installed where the irrigation system tees off the mainline to the house. It is a recommended option for large properties to keep track of the actual volume of water being applied to the landscape. Single-family homes typically have a single mixed-use meter which doesn’t distinguish between indoor and outdoor water use. An alternative is to install a flow sensor working in tandem with a smart controller.

Low-volume irrigation devices like rotary nozzles and micro or drip irrigation are designed to deliver water to the landscape at a slower rate. This better approximates the infiltration rate of the soil and reduces runoff.

Smart controllers will automatically adjust irrigation schedules in response to changing weather conditions. They come in two varieties. ET controllers monitor weather conditions. Soil moisture-based controllers directly sample the moisture in the ground. These devices also have features like “cycle and soak functions that can help eliminate runoff. When selecting a controller, look for brands with the EPA WaterSense ® label.

Water Authority Wins National 2021 EPA WaterSense Excellence Award

/in , /by

The U.S. Environmental Protection Agency has recognized the San Diego County Water Authority with a 2021 WaterSense Excellence Award for advancing water efficiency through its Qualified Water Efficient Landscaper, or QWEL, program. The Water Authority received one of 34 WaterSense awards last week at the national WaterSmart Innovations Conference in Las Vegas.

Due to the coronavirus pandemic, the Water Authority pivoted its QWEL courses to a virtual format. The Water Authority partnered with San Diego Gas & Electric to install nearly 4,000 WaterSense-labeled showerheads for county residents and helped reduce outdoor water waste by using its WaterSmart Contractor Incentive Program to install more than 1,000 WaterSense-labeled irrigation controller stations, saving more than 6 million gallons of water.

“Working collaboratively with the EPA to increase water efficiency by training hundreds of landscape professionals each year makes a significant contribution to saving water, especially during dry times,” said Gary Croucher, Board chair of the San Diego County Water Authority. “The QWEL program is an effective education program for landscape professionals that provides the knowledge and skills needed to help our communities save water and keep landscapes healthy and beautiful.”

EPA WaterSense-QWEL-Excellence Award

The U.S. Environmental Protection Agency has recognized the San Diego County Water Authority with a 2021 WaterSense Excellence Award for advancing water efficiency through its Qualified Water Efficient Landscaper, or QWEL, program.

As one of the first QWEL providers in Southern California, the Water Authority has helped to expand the program’s branded outreach and educational outcomes. Since the January 2016 launch of QWEL, more than 1,400 San Diego landscape professionals have participated, making the region’s program one of the largest in the nation. More than 800 landscape professionals have earned QWEL certificates in the San Diego region over the past six years by passing a rigorous national test.

Landscape water efficiency

The Water Authority promotes English and Spanish QWEL training in collaboration with trade associations, faith-based organizations, English-as-a-Second-Language programs, community colleges and Master Gardeners associations. Nearly all (99%) program participants surveyed said the class would help them better manage landscape water efficiency, and 98% rated the class good or excellent.

This is the third time the Water Authority has achieved the Excellence Award for the QWEL program, which is certified by EPA to significantly increase water management skills and knowledge among landscape professionals.

WaterSense works

WaterSense, a voluntary partnership program sponsored by EPA, is both a label for water-efficient products and homes and a resource for helping consumers learn ways to save water. Since the program started in 2006, WaterSense labeled products have helped consumers and businesses save 5.3 trillion gallons of water – enough water to supply all households in the United States with water for 200 days! In addition to water savings, WaterSense has helped reduce the amount of energy needed to heat, pump, and treat water by 603 billion kilowatt hours and save $108 billion in water and energy bills.

“In 2020, our WaterSense partners continued to make saving water possible by educating consumers and businesses about WaterSense and water-efficient behaviors,” said Veronica Blette, the WaterSense program manager. “Our award winners’ creative and committed approaches to water conservation helped consumers save water, energy, and money on their utility bills at a time when they needed it most.”

The San Diego regional QWEL program is made possible in part by grant funds from voter-approved Proposition 1 administered by the California Department of Water Resources.

Choosing Your Best Irrigation Method: Spray or Drip

/in , /by

Your choices in irrigation methods come down to spray or drip systems. Spray irrigation emits water in an overlapping pattern. Drip irrigation delivers water directly to the roots of plants. This question is more important than ever during a drought cycle. How do you decide which meets the needs of your landscaping?

The case for spray irrigation

Spray irrigation can be an efficient way to irrigate large landscapes with groundcover or uniform plant materials like lawns or meadows.

Spray systems apply water in gallons per minute, so if you know the application rate of each spray head, the distance between the heads, and the pressure of your system, it is relatively easy to figure out how much water is applied every time you run your irrigation.

Low volume spray heads apply water at about one-third the rate of conventional spray heads. Newer spray irrigation heads have improved spray with heavier droplets more resistant to wind. Landscaping with grade changes using spray heads should have check valves installed to prevent water flowing out of the lower point heads.

Challenges of spray irrigation include narrow areas surrounded by hardscape or irregular patterns. Irregular patterns are particularly challenging because spray irrigation requires head-to-head coverage to be efficient. Odd-shaped areas may be under or overwatered. High-volume spray heads that emit water at a much higher rate than the soil can absorb should be replaced.

The case for drip irrigation

Drip systems apply water in gallons per hour, so they often need to run for longer periods of time than spray systems. But the actual run time must always account for precipitation rate and runoff.

Installation of subsurface systems (under at least two inches of mulch) is the most efficient way to irrigate nearly every type of garden area. Since the tubing is flexible, it can accommodate a variety of irregularly shaped areas or rectangular areas when laid in a grid pattern, and in rings you can easily expand as trees or shrubs grow.

Challenges of drip irrigation include the application of water too quickly for your soil to absorb. This needs to be considered when dripline grids are installed. Drip irrigation operates the most efficiently at low pressure (between 15 and 30 PSI). To achieve optimal performance, pressure regulation either at the valve or at the point of connection of the dripline to the buried lateral lines must be used. It is also essential to install some type of filtering system to keep the emitters from getting clogged.

Water Authority’s Ratepayer Protection Case Secures Additional $36 Million Recovery

/in , /by

I am pleased to announce a decision by the Metropolitan Water District of Southern California’s Board of Directors to pay the San Diego County Water Authority damages and statutory interest for illegal water charges from 2015-2017, totaling about $36 million. MWD’s vote followed a California Court of Appeal decision upholding earlier rulings in favor of San Diego.

This payment will bring the Water Authority’s cash recovery on behalf of San Diego County water agencies and ratepayers to more than $80 million. An additional award of attorneys’ fees to the Water Authority, still on appeal, is expected to bring the cash recovery to almost $94 million for rates and charges set by the Los Angeles-based wholesaler over an 8-year period from 2010-2017. Adding in avoided rate increases when MWD stopped imposing the illegal rate, brings the total savings for San Diego County ratepayers to almost $140 million over the 10-year period at issue in the cases.

Collaboration with MWD

I want to thank General Manager Adel Hagekhalil, Chairwoman Gloria Gray and the entire MWD Board for taking this important step toward a more collaborative future. This provides exactly the kind of catalyst we need to resolve the remaining issues between our two agencies.

I also want to acknowledge the collaboration with our peers at MWD over the past several months, working together on the challenges we face including the severe drought conditions across California and how to maintain an affordable and reliable water supply for all of our collective member agencies and ratepayers.

The recovery aligns with the Water Authority’s focus on taking all actions necessary to protect our ratepayers and ensure affordable water rates for future generations. Litigation is never welcome or easy and it wasn’t in this case. But our Board felt there was too much at stake and that an independent tribunal was needed to address and resolve our respective concerns.

Ratepayer protection litigation

Announcement of these ratepayer benefits follows the Water Authority’s distribution seven months ago of a $44 million recovery from MWD for damages and interest in earlier 2011-2014 cases. The money – refunded to the Water Authority’s member agencies in proportion to their overpayments – also resulted from the Water Authority’s ratepayer protection litigation in state Superior Court and positioned its member agencies to reduce future regional water rate increases.

Importantly, the court rulings and guidance are also expected to help avoid future potential taxation of San Diego County ratepayers and minimize future disputes over MWD’s rates.

In February 2020, after the Court of Appeal ruled MWD’s “rate structure integrity” clause unconstitutional, MWD changed its rules to allow Water Authority member agencies to apply for benefits. As a result, the Water Authority’s Board of Directors voted to dismiss these issues from the litigation. Since then, the Water Authority has assisted its member agencies in obtaining nearly $500 million in MWD funding agreements including the City of San Diego’s Pure Water project, which is funded by rates paid by all MWD member agencies including the Water Authority.

The Water Authority is currently working collaboratively with MWD and its member agencies across Southern California to update MWD’s long-term water resource and financial plans. MWD’s Integrated Resources Plan, known as the IRP, will be supplemented by a new “One Water” plan intended to represent the agency’s roadmap for the future and focusing on enhanced collaboration with its member agencies.
