Who Can Use a Fire Hydrant for Non-Emergency Purposes?

Fire hydrants are primarily intended for emergency firefighting operations. However, DC Water may authorize the use of fire hydrants for certain non-emergency purposes through the issuance of a Fire Hydrant Use Permit.

Approved non-emergency uses include:

• Construction activities
• Special events
• Landscaping and irrigation
• Street and sidewalk cleaning
• Water truck filling
• Other temporary water use activities approved by DC Water

What Are the Requirements for Fire Hydrant Use?

Pursuant to 12F DCMR §608.18 – Fire Hydrant Use Connections, any connection to a fire hydrant for purposes other than firefighting must:

• Receive prior approval from DC Water.
• Be equipped with a properly functioning water meter.
• Be protected by an approved backflow prevention assembly.

To use a fire hydrant within the District of Columbia, you must have:

1. DC Water Fire Hydrant Use Permit.
2. DC Water-issued fire hydrant meter.
3. Reduced Pressure Backflow Preventer Assembly (RPBA) that complies with ASSE Standard 1013.

Reduced Pressure Backflow Preventer Assembly Requirements

Customers may either rent a backflow preventer from DC Water or use their own approved backflow preventer.

If using your own backflow preventer, it must:

• Be inspected and tested by a DC Water-approved backflow inspector
• Pass all required inspection and performance tests.
• Have results documented on a Hydrant BPA Inspection Report
• Have an inspection date no more than six (6) months before the date the hydrant will be used.
