How to obtain a hydrant permit
To obtain a permit, bring your meter and backflow test report to Denver Water’s Meter Shop for calibration (call the Meter Shop at 303-628-6701 to make an appointment).
Please allow up to three business days for calibration testing and permit approval. Once the permit is approved, you will be contacted to pick up your meter and permit from the Meter Shop.
All permitted connections to a hydrant must include a hydrant meter, a reduced pressure backflow prevention assembly, proper support with adjustable jack stands or dolly with the use of a hydrant wrench. Denver Water does not provide or rent this equipment. It is the responsibility of the permit applicant to purchase these items prior to applying for a permit.
Why do you require a reduced pressure backflow prevention assembly?
Reduced pressure backflow devices have the lowest risk of human error and can provide consistent and constant protection while attached to the hydrant. A reduced pressure backflow device is required for all connections to a hydrant to protect Denver Water’s distribution system from potential contamination.
Per state of Colorado drinking water regulations, backflow assemblies must be tested annually by a certified backflow tester. In order to obtain a permit for hydrant use, the applicant must provide a valid backflow test report.
Permits must be on site when meter is in use. Copies can be made and kept in trucks for easy access.
The Meter Shop is located at 1600 West 12th Avenue. Check in at the guard shack on 12th Avenue to be directed to the Meter Shop. Meter Shop hours of operation are Monday through Friday, 7 a.m. to 3 p.m. The shop’s phone number is 303-628-6701.
What kind of support is required for meter and reduced pressure backflow prevention assembly?
Denver Water requires permit holders to have adequate support of the meter and backflow assembly while connected to a hydrant to prevent damage. It is imperative that active hydrants are functioning properly to extinguish fires.
Permit holders failing to use proper support while connected to a hydrant can incur fines and possibly be held liable for the costs of repairs to the hydrant. Per Denver Water’s Engineering Standards, the best means of support is the use of three jack stands. See a drawing of the proper placement of the stands.
An alternative means of support may be allowed, such as the use of a dolly. This will be determined by Denver Water staff on a case-by-case basis and must be approved at the time of permit application.

Permits for three months or less do not require monthly read submissions. When the permit expires, return the meter to Denver Water’s Meter Shop for a final reading.
