Drip irrigation tips
Drip irrigation is truly beneficial to plants in desert environments. Drip irrigation systems deliver water more slowly and efficiently, and they should run longer but less frequently than sprinkler systems.
The length of each watering should be determined by the emitter flow rate, soil type, and weather conditions.
It's easy to accidentally overwater your plants on drip systems! Use the information on this page to determine the correct run times for your landscape.

How often to water
Seasonal watering restrictions apply to customers with drip irrigation systems. While drip irrigation may occur any day of the week, the number of days is limited by season.
Plants need far less water than grass. Here's how we recommend you run drip irrigation systems during each season:
- Fall and Spring: Once or twice a week
- Winter: Once a week or every other week
- Summer: 2 to 3 days a week
Remember to avoid Sunday watering and comply with seasonal watering restrictions—or face a water waste fine.
Drip it, don't drown it
Running drip too many days a week is a mistake most homeowners make. Drip irrigation waters plants long and slow and puts water right at the root zone, which means you can water less often.
How long to water
Determine the amount of time to water based on the rate of flow of your drip emitters.
|Emitter type||Length of each watering|
|High-flow emitter (Up to 20 gph)||20 - 40 minutes or less|
|Low-flow emitter (Up to 4 gph)||30 minutes or less|
|Low-flow emitter (Up to 2 gph)||60 minutes or less|
|Low-flow emitter (Up to 1 gph)||90 minutes or less|
High-flow or low-flow? Don't know?
- Low-flow: Beads on tip or drips slowly
- High-flow: Streams like a water fountain
- gph: Gallons per hour, often marked on the emitter head. There are many emitter types.
