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.

DC Water Breaks Ground on Piney Branch Tunnel, Final Phase of DC Clean Rivers Project

Today, DC Water broke ground on the Piney Branch Tunnel, the final major tunnel in our Clean Rivers Project. This work will help keep sewage and trash out of local waterways and make Rock Creek, the Potomac River, and the Chesapeake Bay cleaner for our community.

When we finish the Piney Branch Tunnel, it will hold at least 4.2 million gallons of rainwater and wastewater during heavy storms. Instead of overflowing into Piney Branch, that water will go to the Blue Plains Water Resource Recovery Facility, where it will be treated.
