Stage III High Water Conservation Alert

Stage III High Water Conservation Alert

In response to record-breaking drought conditions and the Governor’s Executive Order calling for an overall 20 to 30 percent reduction in water usage across California, the Chino Hills City Council declared a Stage III High Conservation Alert effective June 1, 2022, in accordance with its Municipal Code. Californians must continue to follow smart water practices to ensure the long-term health of the water supply.

Your Outdoor Watering Days and Times are Designated

Residents and businesses are limited to two watering days per week and shall not exceed 15 minutes per watering station, except for drip or micro-spray irrigation systems, which shall not exceed 30 minutes per station; and are prohibited from watering between the hours of 9 a.m. and 6 p.m.

Watering days for outdoor irrigation are based on street address:

  • Residential addresses ending in an even number may use water on Wednesdays and Saturdays (except from 9 am to 6 pm)
  • Residential addresses ending in an odd number may use water on Thursdays and Sundays (except from 9 am to 6 pm)
  • Non-residential addresses may use water on Tuesdays and Fridays (except from 9 am to 6 pm)

Additional Restrictions of the Stage III High Water Conservation Alert

  • Prohibits application of water to hard surfaces such as sidewalks, driveways, and parking areas, etc., or irrigation causing runoff
  • Requires the repair of leaks within 48 hours
  • Prohibits the use of water hose without a shutoff valve
  • Prohibits irrigating outdoor landscape after measurable rain (1/10 inch or more within a 48 hour period)
  • Limits pool-filling to the above-specified irrigation days
  • Decorative water fountains at commercial properties may only be operated if the water is part of a re-circulating system
  • Vehicles, trailers, boats, and livestock can be washed with a hand-held hose equipped with a shut-off nozzle
  • Restaurants may not serve water unless the customer requests water
  • Water may not run off or leak from landscaped areas to streets, sidewalks, or other paved areas due to incorrectly directed or maintained sprinklers or overwatering
  • Fire hydrants may only be used for firefighting*

*An exception may be made for construction use through a City-designated meter when recycled water is not available.

Stage III Alert Does Not Apply Where Recycled Water is Being Used

The Stage III Water Alert outdoor irrigation requirements do not apply to construction projects or areas where recycled water flowing through purple pipes is used. Many of the City’s parks in the southern part of Chino Hills are irrigated using recycled water so residents may see parks being irrigated on different days than those included in the Alert. City parks, facilities, and public spaces that are not irrigated using recycled water will be irrigated on a schedule in accordance with the new Stage III Water Alert.

Report Water Waste

Residents are encouraged to report violations or leaks through the online form or by downloading the City App. You may also report violations by phone to the City's Water Use Efficiency Coordinator at (909) 364-2804.


The City hopes to obtain voluntary compliance of the Stage III High Water Conservation Alert restrictions, however, per municipal code section 13.08.100 and 1.36.020, fines of $100 for the first, $200 for the second, and $500 for the third violation can be imposed.
