Frequently Asked Questions

What days can I water my lawn in Chino Hills right now?
It depends on which conservation stage the City Council has declared. Under a Stage II Moderate Alert, even-numbered addresses may irrigate Monday, Wednesday and Saturday and odd-numbered addresses Tuesday, Thursday and Sunday, always before 9 a.m. or after 6 p.m., per CHMC § 13.08.070(A).
Can drip irrigation run longer than sprinklers?
Yes. Section 13.08.070(A) caps standard sprinkler stations at fifteen minutes but allows drip or micro-spray systems to run up to thirty minutes per station during the same permitted watering windows.
Can the City shut off my water for breaking the watering schedule?
Yes. Section 13.08.100(F) lets the City Manager install a flow restrictor, lock or remove the meter, or disconnect service outright for violations, and the customer is billed for the City's enforcement costs.
Is there any relief if I can't afford to comply?
Yes. The Public Works Commission can grant a financial-hardship exemption under § 13.08.040(B) if a customer shows compliance would cause extreme, unmitigable financial hardship, following a written request filed at least two weeks before the Commission meeting.
