Prohibited Uses of Water

Cal Water wants to ensure our customers are aware of the following prohibited uses of potable water:

  • Applying water to outdoor landscapes that causes runoff onto adjacent property, non-irrigated areas, private and public walkways, roadways, parking lots, or structures
  • Using a hose to wash motor vehicles unless the hose is fitted with a shutoff nozzle or device that causes it to cease dispensing water immediately when not in use
  • Applying water to driveways and sidewalks
  • Using water in a water feature, except where the water is part of a recirculating system
  • Applying water to outdoor landscapes during and within 48 hours after measurable rainfall (0.25 inches)
  • Irrigating outside of new construction without drip or microspray systems
  • Irrigating landscape between the hours of 8 a.m. and 6 p.m., and irrigating outside of approved watering days for districts observing Stage 2 restrictions*

*Some cities or counties may have adopted, or may do so in the future, additional restrictions on water use and/or outdoor irrigation that may be more restrictive than Cal Water’s. Please be sure you are aware of and abide by any such restrictions; in the event of a conflict between those restrictions and Cal Water’s restrictions, those adopted by cities and counties shall govern.

Additional Water Use Restrictions

  • Customers must fix leaks within their control within five business days of notification
  • Hotel/motel operators must provide option to not have towels or linens laundered daily during a guest’s stay, and must provide clear notice of this option in easy-to-understand language
  • Restaurants and other eating and drinking establishments may only serve drinking water upon request (If you are a restaurant operator and would like table tents to explain this restriction, please contact Cal Water’s Conservation Department.)

The State Water Resources Control Board also adopted restrictions regarding irrigating ornamental turf in street medians and utilizing water for street cleaning and construction. These restrictions are reflected in Stage 3 of our Water Shortage Contingency Plan, and will be enforced if Stage 3 is enacted in any of our service areas.

If you happen to see someone wasting water, we want to know about it so that we can work with them to use water wisely. You can use our online form to report leaks and waste.
