Mandatory Watering Restrictions

Assigned watering groups are mandatory for all customers. Running your sprinkler irrigation system outside your assigned days is water waste and may result in a water-waste fee or citation.

Drip irrigation

Watering restrictions also apply to drip irrigation. Experts agree that running drip irrigation less frequently is much better for plants than daily watering. Because deep watering is more important than frequency, SNWA recommends a single, long drip cycle of 30 to 90 minutes. See our drip watering tips for details.

Additional restrictions

• Sprinkler irrigation is prohibited between the hours of 11 a.m. and 7 p.m. from May 1 through Sept. 30.
• Sunday is not an optional watering day during the fall, winter and spring (Sept. 1 through April 30).

Exemptions

Exceptions to current watering restrictions include hand-watering, supervised sprinkler system testing and watering new or reseeded landscapes for 30 days. Some water agencies have special requirements to obtain the exemption. Contact your water utility for details.
