New Water Conservation Ordinance


Due to dry conditions over the past three years, the Governor declared a statewide drought and the Metropolitan Water District issued a “Water Supply Alert” for its service area, which includes the City of Chino. In anticipation of reduced imported water supplies, the City of Chino amended the water conservation ordinance in its Municipal Code at the May 5, 2009 City Council meeting. The amended water conservation ordinance includes the following mandatory water use restrictions:

Prohibited Water Uses at All Times

Allowing irrigation water to runoff into paved surfaces such as gutters and streets.

Outdoor irrigation of landscape for more than 15 minutes (Does not apply to landscapes that utilize drip irrigation systems).

Irrigating landscapes during the hours of 6 a.m. to 8 p.m. (Does not apply to irrigation by a handheld hose with an automatic shutoff nozzle, drip irrigation, or handheld buckets).

Irrigation of landscapes on rainy days.

Failure to repair leaks within a reasonable period time.

Washing down paved surfaces such as driveways, sidewalks, and alleys except when necessary to alleviate health and safety hazards.

Washing vehicles at your home unless done with a handheld bucket or hose equipped with a positive shutoff nozzle.

Restaurants serving water to a customer except when specifically requested by the customer.
