Applying for a permit takes about 15 minutes. You may also need to factor in time to have your water tank inspected.
Before requesting a permit
To qualify for an annual permit, you must have your truck- or trailer-mounted water tank air gap inspected and approved by Water Bureau staff. These inspections are good for three years. Call the hydrant permit coordinator to schedule your air gap inspection.
Using your annual hydrant permit
Your permit allows you to use hydrants authorized for annual permits. You may not use hydrants that are not authorized. Find authorized hydrants on this interactive map. Authorized hydrants have a blue ring on the front.
How to request an annual hydrant permit
Call the hydrant permit coordinator at 503-823-1256. You'll need to have this information ready:
- Company name
- Truck license number
- Copy of the current water tank inspection report from the Water Bureau Water Quality Inspector
- Credit or debit card number (for payment)
Water Bureau staff will collect payment from you and then mail you the permit tags and receipt.
In person (by appointment only)
You can buy your permit in person at the Water Bureau meter shop. You'll need an appointment; please call 503-823-1256 at least two days in advance. We offer appointments Monday through Thursday from 8:00 am to 3:00 pm. If you buy the permit in person, you'll receive your permit tags and receipt at the appointment.
The meter shop is at 1850 N Interstate Avenue. If you're using GPS or a map app for directions, use 701 N Hancock Street as your destination and then enter the Portland Water Bureau gate on the left. The meter shop is on the left by the gas pumps.
