Fire Protection

Requesting a New Hydrant

Individuals can submit a request for new fire hydrants to be installed in order to boost fire protection. Per Tennessee state law, all fire hydrants must produce a minimum flow of 500 gallons of water per minute (gpm), with a minimum residual pressure of 20psi, and water lines must be at least six inches in diameter for fire hydrant connections. Some local planning authorities and fire departments require higher flow rates than the state minimum (500 gpm), so please check with your local authorities prior to submitting a hydrant request. You will have to include this information on the request form.

Upon request, WHUD’s engineering team will review the location, pressure and flow of proposed hydrants to determine if installation is feasible. Once the assessment has been completed, someone from WHUD’s engineering department will contact you with the results. If it is determined that a hydrant can be installed in the requested location, the material and installation fee of $4,000 must be paid before the hydrant is installed.

Flow Test on Existing Hydrant

Individuals can also request flow tests on existing hydrants. The test will scheduled and results provided within 25 business days of the request. The fee for this service is $100.

Hydrant Mapping Program

In addition to installing new hydrants and testing existing ones, WHUD is using advanced mapping software to help local fire departments keep their hydrants functioning at max capacity. The map, built in WHUD’s geographic information system (GIS), has increased efficiency, increased repair time, allowed for real-time notification of issues/repairs, enabled fire departments to plan for future growth, and improved fire protection for the community.
