How to request a temporary hydrant permit

To apply for a temporary hydrant permit please email the coordinator with the following information at :

  • Provide Company information and contact person
  • Where is the hydrant location?
  • What in the purpose for the hydrant permit?
  • Are you looking for a direct connection or filling a tank?
  • When are you looking to get started?
  • How long would you like to use the hydrant?
  • Do you have your own chapman valve and wrench?

Approval process can take up to 7 days so please plan appropriately.  There will be no emergency permits issued due to water quality concerns. Based on this information, we will estimate and collect the anticipated permit cost and deposit, prepare the permit tag, and issue you the required equipment. All hydrants are not available for construction use. 

Equipment you'll need

To use a hydrant, you'll need a Chapman (hydrant) valve, spanner wrench, water meter, and backflow prevention device. You can rent that equipment from us.

Temporary hydrant permit fees and payment

Our hydrant permit coordinator will estimate your permit cost based on the fees in the table below. This is an estimate because your actual permit cost will depend on how much water you use. You must pay the estimated cost before getting your permit. You can pay your permit fee online, by calling 503-823-1256, or by visiting our Interstate facility.

Permit fee (includes 700 cubic feet of water)$290.00
Fee for each additional 100 cubic feet of water$7.006
Equipment rental fees:
  • Chapman valve and spanner wrench (rents as a set)
  • Water meter
  • Backflow prevention device

Each of these costs $9.15 for the first three days and $3.05 for each additional day.

You must also pay a $1,975 deposit to rent this equipment.

Setting up and using the hydrant

Before turning the hydrant on, follow these instructions to install the rental equipment provided by the Water Bureau:

  1. Use the spanner wrench to remove a port cap on the side of the hydrant.
  2. Ensure the Chapman valve is closed. Screw it onto the port on the side of the hydrant.
  3. Attach the hose to the Chapman valve.
  4. Attach the meter to the hose.
  5. Attach the double check backflow device to the meter.
  6. Check all the equipment connections. Tighten with the spanner wrench if necessary.
  7. To open hydrant, use the spanner wrench to turn the top nut counterclockwise in twelve complete turns.
  8. Start the flow of water through the hose and equipment by turning the handle on the Chapman valve. Control the flow of water with the Chapman valve, not the top of the hydrant stem.

If the hydrant malfunctions—including if it vibrates when it flows or if water bubbles from its base of the hydrant—stop using it immediately and call the Water Bureau Emergency Line: 503-8234874.

Shutting down the hydrant and disconnecting equipment

  1. Use the handle on the Chapman valve to stop the flow of water.
  2. Close the hydrant by using the spanner wrench to turn the top nut clockwise for twelve complete turns.
  3. Unscrew the double check backflow device, meter, hose, and Chapman valve.
  4. Before replacing the cap on the port on the side of the hydrant, check inside the hydrant barrel to make sure the water level is dropping.
  5. If water is still flowing, that means the hydrant is not fully shut off. Use the spanner wrench to turn the top nut in eighth-turn increments until fully closed.
  6. Do not overtighten the hydrant when closing.

​Closing your temporary hydrant permit

When you return the equipment, the hydrant permit coordinator will generate the final bill. The final bill is based on the following information:

  • The date you're returning the equipment
  • Meter readings
  • Equipment numbers
  • All equipment is broken down or separated before returned (we will charge you a $25 fee if equipment is still attached when returned)
  • Any equipment not returned (we will bill you the replacement cost)
  • Repair cost of any equipment damaged during your rental

If you don't have any additional charges, we'll refund your deposit. If you do have additional charges, we'll apply your deposit towards the final billing and refund you the remaining balance from your deposit. 

We generally refund deposits one to two weeks after you return the equipment.
