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.

Why Southern California Fears Too Much Water Conservation

As Gov. Gavin Newsom weighs new mandatory drought restrictions, Southern California leaders fear cuts in urban water use could force already sky-high water bills ever higher.

Unlike much of Northern and Central California, the region isn’t hurting for water, yet. Top water officials insist they have enough supplies for at least one more hot summer, perhaps two.

As Drought Worsens, California Farmers Are Being Paid Not to Grow Crops

Green fields of alfalfa and cotton rolled past as Brad Robinson drove through the desert valley where his family has farmed with water from the Colorado River for three generations. Stopping the truck, he stepped onto a dry, brown field where shriveled remnants of alfalfa crunched under his boots.

The water has been temporarily shut off on a portion of Robinson’s land. In exchange, he’s receiving $909 this year for each acre of farmland left dry and unplanted. The water is instead staying in Lake Mead, near Las Vegas, to help slow the unrelenting decline of the largest reservoir in the country.

Water Authority Wins National 2021 EPA WaterSense 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. 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.

Opinion: Up to 1 Million Gallons of Water … a Night? That’s Par for Some Desert Golf Courses

Doug Thompson couldn’t believe what he’d just been told. His wife, a botanist, was advising a Coachella Valley country club on drought-resistant landscaping, and Thompson, who got to talking with the groundskeeper, asked how much water it takes to irrigate a golf course.

Opinion: Conserving Water Can Cut Our Bills and Help Future Generations

Extended droughts broken up by rainy years are part of a natural cycle here in California. Our state is once again in another dry period, with areas of Northern California already experiencing a significant impact. It is not a question of if, but when the Coachella Valley faces a similar fate.

Thanks to decades of targeted projects and careful planning, Mission Springs Water District will have enough water to serve our 40,000 customers in and around Desert Hot Springs.

California Drought: Which Cities in Santa Clara County are Saving the Most and the Least Water

The Santa Clara Valley Water District, which is the main wholesale water provider in Santa Clara County, on June 9 declared a drought emergency and called on all residents to reduce water use 15% from 2019 levels to preserve supplies.

In August, the most recent month for which data is available, countywide water use dropped by 9%. That was an improvement from a 6% drop in July, but still is significantly under the goal.

Here is the percentage change in water use between August 2019 and August 2021 at the 13 cities and private water companies the Santa Clara Valley Water District serves.

Drought Emergency: San Jose Mayor Liccardo Proposes Outdoor Watering Limits To 2x/Week, Renews Calls To Conserve

San Jose Mayor Sam Liccardo renewed calls for residents to conserve water and proposed outdoor watering restrictions Wednesday as California’s ongoing drought deepens.

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?
