Sprinklers & Irrigation


Irrigation & sprinkler resources

  • The Association of California Water Agencies web portal is a one-stop-shop for homeowners and professionals looking for information and online resources on water-efficient irrigation. Homeowners will find easy-to-understand information about how residential sprinkler systems work, information on drip irrigation and other smart ways to reduce landscape water use, as well as loads of online resources. The portal was created as part of the association's Save Our Water campaign.

  • For irrigation professionals, the Irrigation Association has a wealth of irrigation information including online learningvideos and webinars, and technical resources.

  • Find local irrigation supply stores that carry water-efficient irrigation equipment.

  • For agriculture-specific irrigation information, see the irrigation calculator for growers.

  • Visit South Bay Green Gardens to find landscape designs, sample project photos, lists of professionals to help complete your project, and more.

Sprinklers & irrigation best practices

  • Minimize evaporation. Water between 9 p.m. and 6 a.m., and use a 2-3 inch layer of organic mulch around plants. 
  • Eliminate runoff. Check your irrigation system frequently, and adjust sprinklers for overspray and runoff. Divide your watering cycle into shorter periods.
  • Plants and watering. Change plant material to low-water use or native plants. Water plants deeply but less frequently to create healthier and stronger landscapes. Santa Barbara offers this 7-minute overview of how to deep water trees so they stay healthy and hydrated while using less water.
  • Water only when needed. Using a screwdriver or moisture meters as a soil probe, test the soil moisture. If it's moist, you probably do not need to irrigate. Install a rain shut-off device on your automatic sprinklers to eliminate unnecessary watering.

Creating a water budget

The water budget considers the landscape area, plant type, plant water needs, irrigation system design and efficiency, and real-time water that the landscape receives either by irrigation or precipitation. Water budgets must be associated with a specified amount of time, such as a week, month, or year.

  • Properties and landscapers can get help creating a water budget at Waterfluence.com, if they pre-qualify. 
  • Commercial property owners may qualify for assistance through our Large Landscape Program.

Irrigation controllers

Sometimes referred to as timers or clocks, an irrigation controller is a device that operates automatic irrigation systems, such as lawn sprinklers and drip irrigation systems. Irrigation controllers help you adjust your irrigation schedule to avoid overwatering, increased cost and maintenance, and property damage. Most controllers have a means of setting the frequency of irrigation, the start time, and the duration of watering. They can be as simple as a clock (inefficient), can connect to your phone, or only irrigate when needed based on soil moisture or local weather stations. 

Valley Water offers rebates for installing more efficient irrigation controllers.

Lawn care

Lawns can be the single biggest water user for a typical property; a small lawn can use more than 18,000 gallons a year. That means lawns offer the greatest potential for water savings! Find tips for reducing water use and caring for your lawn on our Landscape Guides and Resources page.
