Efficient Irrigation Delivers Water While Protecting Plants

/in , /by

Due to the lack of rainfall in the San Diego region, even sustainable landscaping sometimes relies on artificial irrigation. Irrigation systems must be thoughtfully designed, installed, and programmed. Once in place, the many interconnected mechanical elements must be maintained properly for optimal performance.

“Irrigation efficiency” is a way of describing how well your irrigation system is doing its job delivering water for the beneficial use of the plants in your landscaping.

When irrigation system efficiency isn’t maximized, it can cause you to use more water than needed. Possible problems fall in three major categories: site conditions in your landscaping, irrigation control, and the uniform distribution of water by your irrigation system.

There are three ways to improve your irrigation system efficiency:

  • Smart Irrigation Management
  • State of the Art System Upgrades
  • Matching Irrigation to Your Hydrozones

Setting and forgetting your irrigation controller is a thing of the past. Even if you don’t have a “smart” irrigation controller to adjust your program for weather conditions, be more proactive in managing your watering, and more closely try to match your watering schedule with the actual water needs of your landscaping.

Upgrading your system with state-of-the-art components is a good investment and the single most significant thing you can do to save water.

Tips on professional help

You may decide to get professional help with your irrigation system. Look for designers or contractors qualified to provide these services. Credentials such as the Irrigation Association’s Certified Irrigation Designer designation can help assure your project will be successful. You can also ask if your contractor is a Qualified Water Efficient Landscaper (QWEL).

This article is part of a year-long series inspired by the 71-page Sustainable Landscapes Program guidebook. The Water Authority and its partners also offer other great resources for landscaping upgrades, including free WaterSmart classes at WaterSmartSD.org.

Marin County water officials said there is no room for delay if the county hopes to build a $65 million emergency water pipeline across the Richmond-San Rafael Bridge.

Reservoir depletion in the Marin Municipal Water District has prompted one of its board members to call for stricter water conservation measures to buy more time and to have a more solid backup plan should the pipeline project fall through.

On Aug. 3, the State Water Resources Control Board completely eliminated 2021’s surface water supplies for farms in much of the state. It has impacted farmers like John Moore III, who grows pistachios at Moore Farms in Arvin.

“We’ve got about 100 acres of pistachios, 200 of almonds and everything else goes to open farmland, carrots, potatoes and we have a small block of citrus as well that goes to both domestic and export buyers,” said Moore

Outdoor water-efficiency rebates

Outdoor water use is 53% of the water used by residential properties. Most of that water is applied to keep grass green. There are a variety of rebates and classes that can help you upgrade your turf landscape to a beautiful sustainable, water-saving landscape. To learn more, visit WaterSmartSD.org. Available rebates include:

  • Turf Removal – Rebates start at $3 per square foot for qualifying projects that replace grass with landscapes that incorporate water-saving plants, irrigation system upgrades and rainwater capture.
  • Weather-Based Irrigation Controllers – Rebates start at $80 for controllers that automatically adjust the irrigation schedule to account for changing weather, soil conditions and plant types. For landscapes large than one acre, rebates start at $35 per station. Homeowners can save 8,800 gallons of water annually by replacing a standard clock timer with a WaterSense-labeled irrigation controller.
  • Rain Barrels – Rebates start at $35 for up to two rain barrels, or $250-$350 for a cistern to collect rainwater for later use, while minimizing the amount of water flowing into storm drains, sewer systems and local waterways.

Could California Weather a Mega-Drought?

/in , , /by /UC Davis Water Sciencesby Jay Lund

“Mega-drought” has become a frightful “thing” in public and media discussions.  In the past 1,200 years, California had two droughts lasting 120-200 years, “megadroughts” by any standard. Could the state’s water resources continue to supply enough water to drink, grow crops and provide habitat for fish with such an extreme, prolonged drought today?

Clearly, some ecosystems and rural communities would be devastated by such a drought, and it would certainly affect all California residents.  But with careful management, California’s economy in many ways could substantially withstand such a severe drought.
