Notice of intent to drill a well for a grow
Licensing & registrationLast verified Nov 7, 2026
A well drilling contractor must apply for and receive OWRB approval before drilling a non-domestic groundwater well. Intent-to-drill authorizations are required for medical marijuana grow operations, and will not be issued for a location without an active groundwater use permit. OWRB staff respond in about 5 business days.
Why it matters
Get the water permit first; without it the driller cannot get authorization.
Applies to Grower/Processor/Dispensary/Transporter/Lab
