How is Cal Water conserving water?

At Cal Water, we’re taking steps to conserve water by not only monitoring our own facilities and water pipelines but also:
- Replacing, repairing, and upgrading infrastructure to minimize water loss
- Identifying and repairing leaks through a Water Loss Auditing and Control Program
- Developing 30-year Water Supply and Facilities Master Plans, which enable us to identify and address potential gaps in supplies
- Updating Conservation Master Plans for each district to implement programs that maximize water savings for all our customers
Can I hand water plants and other fixtures?
Hand watering is allowed and exempt from irrigation day schedules. If you use a hose, use a nozzle with a shutoff valve and stay vigilant to confirm that you don’t overwater.
Can I water my trees?
Cal Water encourages you to continue watering trees, as it will take more water to replace a mature tree than to keep it alive. Hand-watering is exempt from watering day restrictions. If using an irrigation system, watering should occur on assigned irrigation days. You can water trees responsibly by checking the soil prior to watering, allowing water to soak slowly, using mulch to retain moisture, and following other guidelines provided by experts.
Should we stop irrigating after measurable rain?
You should stop irrigating during and for 48 hours after you receive measurable rainfall. Measurable rainfall is any amount of precipitation more than one-quarter of an inch.
What is the recommended run time for irrigation?
Unless local ordinances specify time limits, we recommend watering 5-7 minutes, 2-3 times per assigned day, to maximize the benefit of irrigation.
Why aren’t hoses limited like sprinkler systems?
Some customers wonder why it’s okay to hand-water with a hose and shut-off nozzle on any day, but not okay to water with a sprinkler system set to only water landscaped areas for a specific amount of time?
Hand-watering with a hose and shut-off nozzle allows for more targeted watering. While a sprinkler system may only water for a specific amount of time, it may cover a larger area that has portions that do not need to be watered and may water longer than needed. Hand-watering conserves water because users are able to target only what needs irrigation and stop when enough water has been applied.
How do I program my smart irrigation controller?
Cal Water recommends consulting the user guide provided by the manufacturer to learn how to adjust the programming of your specific controller.
