Fall Back and Save Water As Clocks Change

Whether you are excited about an extra hour of sleep or dour about losing an hour of sunlight at the end of the day, daylight saving time ends Sunday, Nov. 4. The annual adjustment is a great reminder to perform several important household tasks, such as replacing smoke alarm batteries and restocking emergency preparedness kits.

The San Diego County Water Authority asks residents to add one more important task when changing the clocks: Adjust irrigation systems to save water in the months ahead.

“Adjusting irrigation is an easy way to conserve water, since landscapes need less irrigation as the days get shorter and cooler,” said Dana Friehauf, a water resources manager for the Water Authority. “Residents also should make sure their irrigation systems are working correctly, and are free of broken sprinkler heads or other leaks that waste water.”

Approximately half of a typical California household’s water use is outdoors. Seasonal adjustments to irrigation controllers in preparation for winter weather not only reduce water waste, they benefit the health of landscape plants.

Cool-season water-saving practices can reduce use

Additional water-saving practices during the fall and winter months include:

  • Turning off irrigation systems when rainstorms are predicted.
  • Leaving irrigation systems off for at least a week after significant rainfall.
  • Installing rain barrels or cisterns to help capture stormwater from roofs and store it for future irrigation use.

Fall is also the ideal time for residents to upgrade thirsty turf yards to WaterSmart sustainable landscapes. Homeowners can take advantage of winter rains to help establish a new landscape. The Water Authority’s award-winning WaterSmart Landscape Makeover Program offers a variety of free classes and how-to online videos to guide homeowners through the conversion process. More information is at WaterSmartSD.

In addition, there are a limited number of residential rebates available for homeowners who want to upgrade to sustainable landscaping at SoCal Water$mart.

The Water Authority offers additional water-saving resources for residents and businesses through its Live WaterSmart campaign. These include:

  • Free water-use surveys and irrigation checkups
  • Rebates for highly efficient irrigation equipment, washing machines and other devices
  • Water-efficiency training for professional landscapers
  • An online home water-use calculator and other tools

Your plant choices should be governed by the individual hydrozones in your landscaping. Photo: Kelly M. Grow/ California Department of Water Resources

Playing by the Hydrozone Landscaping Rules

Hydrozones are the different areas of your landscape with different irrigation needs. These needs can vary greatly in a single yard. By managing your water distribution to meet the needs of each hydrozone, you can minimize water waste and promote healthy plants.

For example, plants with similar growing requirements including water needs should be planned and planted together so water can be applied as efficiently as possible through rainwater catchment, supplemented by irrigation. 

The amount of sunlight and shade, temperature differences, soil conditions, slopes, and plant root depth should be considered, along with plant water needs, to create hydrozones. Even when the soil is the same, a full sun area is one hydrozone, full shade areas are another, and mixed exposure areas create yet a third zone.  

Within your irrigation system, each individual irrigation valve should water a separate hydrozone populated by plants with similar water needs, living conditions, and root depths. Plants with high water needs such as vegetables or lawns must be on their own hydrozone. Sprinklers or emitters on this zone shouldn’t water anything else, including hardscape areas such as sidewalks.  

Don’t overdo it with irrigation 

 Each hydrozone should have sprinklers or emitters generating the same amount of water, and they should be spaced out so that every plant in the zone gets the same amount of water. If the spray of two sprinklers overlap, plants receiving water from both will receive much more water than they need. In cases like this, sprinklers should be turned away from each other, or placed farther apart. Professional landscapers call this “matched precipitation.”

Oroville Dam Repairs Aren’t Enough, Feds Warn. Should State be Forced to Plan for a Mega-Flood?

Federal regulators are raising new concerns about the troubled Oroville Dam, telling California officials their recently rebuilt flood-control spillways likely couldn’t handle a mega-flood. Although the chances of such a disastrous storm are considered extremely unlikely — the magnitude of flooding in the federal warning is far greater than anything ever experienced — national dam safety experts say the Federal Energy Regulatory Commission’s concerns could have costly repercussions for California. The public agencies that store water in Lake Oroville may be forced to spend millions of dollars upgrading the dam.

Water Managers Along Colorado River Figure Out How To Live With Less

Climate change is growing the gap between the river’s supply, and the demands in the communities that rely on it, including seven western U.S. states and Mexico. The federal government recently released proposals called Drought Contingency Plans designed to keep the Colorado River’s biggest reservoirs from falling to levels where water is unable to be sent through the dams that hold up Lakes Powell and Mead.

A CVWD Candidate Tries to Tip the Balance of the Board Away From Farmers. Here’s Why

The election for the District 3 seat on the Coachella Valley Water District board could be pivotal for the agency’s future as a challenger works to unseat the current board president, potentially tilting the balance of power away from large agricultural landowners. Ed Muzik, general manager of the Hi-Desert Water District in Yucca Valley, has tried to unseat incumbent John Powell Jr., one of three farmers on the water board, with claims that he is the “non-conflicted” candidate in the race.
