Fall Back and Adjust Irrigation Systems to Save Water

/in , , /by /Water News Network Quoted: San Diego County Water Authority

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. Using water efficiently indoors and outdoors is easier than ever thanks to online resources offered by the Water Authority at www.watersmartsd.org.

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.

It’s not March and there was no miracle.

A strong atmospheric river dumped record rain on Northern California last weekend and sent some modest showers to San Diego.

The downpours helped replenish the state’s dwindling reservoirs some, but not enough for Gov. Gavin Newsom to lift the drought emergency he expanded to the entire state last week.

San Diego County’s Water Agency Asks Residents to Cut Water Use by 10%

/in , , /by /NBC 7 San Diego by Audra Stafford Quoted: San Diego County Water Authority

The San Diego County Water Authority voted Thursday to activate Level 1 of its six-part Water Shortage Contingency Plan, which asks San Diegans to voluntarily conserve 10% of their water use.

The vote from the agency’s 36-member Board of Directors came after Gov. Gavin Newsom extended a drought emergency declaration statewide last week as the western U.S. entered its third year of drought.

The declaration — activated twice before in 2007 and 2014, required water suppliers to implement their water shortage contingency plans, however, the Water Authority said it was already planning to implement its plan before the declaration was extended.

As part of Level 1, San Diegans will be asked to voluntarily conserve up to 10% of their water use. The Water Authority will also step up its outreach and education efforts to promote conservation.

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.

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.

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, 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
  • Rebates for indoor and outdoor water saving devices

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.

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.
