Escondido HOA Saves Water, Costs with WaterSmart Landscape Upgrades

The Emerald Heights homeowner’s association in Escondido recently completed a successful clubhouse upgrade including a landscaping makeover replacing existing turf with a beautiful drought-tolerant design.

The gated community is located within the Vallecitos Water District. It covers 6.2 acres including a private athletic club with tennis and basketball courts, plus a community pool and spa. The landscape of turf and trees surrounding the clubhouse area was not healthy. But it would be challenging to find plant materials well suited to growing in the microclimate under the shade trees.

Emerald Heights HOA representatives met with O’Connell Landscape and Maintenance. Jack Rush, O’Connell’s executive vice president of operations, encouraged the HOA to take advantage of the SoCal WaterSmart turf replacement program.

“It incentivized them by offering rebates to help offset the construction costs [for the clubhouse],” said Rush.

WaterSmart landscape features appealing new look

The HOA had invested in irrigation system upgrades two years ago, including “baseline” smart controllers throughout the community. HOA board president Dan Cannon and committee members worked with HOA property manager Telsa Dubois of Allure Management and O’Connell Landscape Management, project manager Salvador Alvarado, and construction supervisor Basilio Diaz to craft the new plan.

Dry riverbed areas were established in place of existing turf, graded to capture water runoff into these areas. Cobblestones and boulders were added, along with plants featuring different leaf textures and unique flowers. Using plants at different heights enhanced the landscape area and gave it a more eye-appealing look.

Throughout the property, point-to-point drip system irrigation was installed. All remaining spray heads were replaced with drip fixtures.

Ongoing savings help pay for community upgrades  

O’Connell applied for the incentive program on behalf of Emerald Heights HOA through the Metropolitan Water District of Southern California. It was able to remove 2,746 square feet of turf surrounding the clubhouse and tennis court areas. The HOA received $8,238 in rebates for the turf replacement.

“The water savings is still too early to tell, but we estimate 50% to 60% water savings are possible,” said Rush, based on the new plant materials and irrigation retrofitting. Rush says his firm will continue to explore more potential water savings for the community and work closely with members of the HOA.

The Emerald Heights HOA can file a turf replacement application each year to receive more turf rebates. Removing thirsty grass is one of the most water-conscious adjustments it can make to reduce its water usage and associated costs.

The Turf Replacement program is a two-part application process. To qualify for a rebate, customers must apply to reserve rebate funds before starting their project. The landscaping makeover must take place with 180 days, including the request for a rebate. Funding levels are subject to change based on availability at the time of rebate approval.

Fall Back and Adjust Irrigation Systems to Save Water

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.

Farmers Propose Solutions to Drought Conditions in the Western United States

The Family Farm Alliance aims to protect water for Western agriculture and describes itself as a powerful advocate before the government for family farmers, ranchers, irrigation districts, and allied industries in 17 Western states. The drought-stricken Klamath Basin is one area that they’ve identified as needing legislative change.

The alliance says it has this goal to ensure the availability of reliable and affordable irrigation water needed to produce the world’s food, fiber, and fuel.

Boost Your Irrigation IQ

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.

Research Seeks Resilience for Aquifers

One day in early October, a group of University of California, Merced, students went to the campus Smart Farm, augurs in hand, to explore the soil for the best spots to locate moisture sensors. They were not looking in the root zone to monitor how much water is available but instead for areas lower in the soil to study how irrigation and stormwater can travel far enough beneath the plants to recharge the groundwater below.

Choosing Your Best Irrigation Method: Spray or Drip

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?

Choosing Your Best Irrigation Method: Spray or Drip

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.

Opinion: What if Farmers Really Could Use 50% Less Water? Arizona Would Be a Different Place

What if farmers could use half the water than they are now without sacrificing crop yield?

Arizona would be a different place.

There are roughly 946,000 acres of farmland in the state, according to the most recent federal farm census in 2018, using an estimated 4.4 million acre-feet of water.

Give Your Irrigation System a Fall Checkup

Staying on top of your irrigation system – especially in the midst of a drought – can mean the difference between maximizing your water efficiency and unknowingly wasting water running down sidewalks unused into the storm drain. Follow these tips for a thorough checkup.

Turn on each valve of your irrigation system and observe how quickly water begins to run off your landscaping. Note the time when each runoff occurs. For some systems, this could be immediate. For others, it may take as long as five minutes.

Make sure spray irrigation is never running for longer than eight minutes at any one time.

Take notes on your irrigation plan, and turn off your irrigation until you can fix the following issues:

  • Do you have broken sprinkler heads?
  • Are there heads that are blocked by plants or objects such as planters or lights?
  • When the system turns off, does water come out of the lowest heads in the landscape?
  • Are any heads in need of adjustment, so they don’t directly spay onto the hardscape, such as sidewalks or patios?

Adjust your sprinklers to eliminate runoff

Several things can be done to minimize runoff due to irrigation. This is among the most important factors in using irrigation efficiently.

  • Tune up spray irrigation systems, so there is no overspray on hard surfaces
  • Do not install spray irrigation in areas that are too narrow (generally eight feet wide or narrower)
  • Move spray heads 24 inches away from buildings or impermeable surfaces
  • Convent spray systems to micro or drip irrigation with pressure regulation and a filter
  • In lawn areas, be sure to follow the organic maintenance practices to keep your soil ‘spongy’ (link to soil post)
  • Replace standard overhead sprayers with high-efficiency rotator nozzles, or other types of low precipitation rate nozzles
