What is the average age of fire hydrants in municipal water distribution systems?
Fire hydrants in municipal water systems average around 50 years old, with some dating back to 1910—a century old. A field survey of just 25 hydrants between a workplace and Highland Park revealed this stark reality: the newest was only 5 years old, while the oldest had served communities for over a century.
The infrastructure crisis becomes apparent when looking at real data from the field. Survey respondents at industry trade shows reported hydrant ages ranging from 10 to 50 years old, but this broad range masks a deeper problem—many utilities lack precise knowledge of their asset inventory.
A walk through Highland Park reveals the full picture
As Paul Gifford explains in the episode, taking a direct measurement approach can be eye-opening. Rather than rely on aggregate estimates, Gifford recorded the installation dates of 25 fire hydrants on his walk home from work, creating a snapshot of real municipal infrastructure age.
The findings paint a clear picture: the average age of these 25 hydrants came to exactly 50 years. The spread was dramatic—the oldest hydrant, still in service, dated to 1910, while the newest had been installed roughly 5 years prior. This distribution tells a story of aging infrastructure with minimal recent replacement in that particular area.
The implications are significant for water utilities managing these systems. Mueller Water Products has documented that broken and corroded parts commonly appear in fire hydrants around 40 years old, suggesting that many utilities are already operating equipment well past the threshold for expected degradation.
"Never be satisfied with the way things are. There's always something better."
Paul Gifford — Product Management Group Representative at Mueller Water Products. Paul began his engineering career in the valve and hydrant industry in Elmira, New York, working in foundry operations, product development, and quality assurance. After a diverse career path, he has returned to hydrant innovation at Mueller Water Products in Chattanooga, Tennessee, where he leads product management and drives solutions like the Hydrant Renewal program. His daughter also works as an engineer at Mueller Water Products.
One particularly telling detail from the episode is how Gifford's personal observation method—simply walking home and recording dates—proved more revealing than broad industry surveys, highlighting the gap between what utilities think they know about their infrastructure and what direct assessment reveals.

How do water utilities currently use fire hydrants beyond firefighting purposes?
Water utilities primarily use fire hydrants for flushing water lines and for inspection of the pipeline system. Technicians can place cameras down through a hydrant to inspect the pipeline infrastructure and identify issues.
What is the Hydrant Renewal program and how does it integrate technology into aging fire hydrant infrastructure?
The Hydrant Renewal program allows Mueller Water Products to take fire hydrants up to 75 years old and rebuild them completely while integrating modern technology, extending their operational life and adding new capabilities to aging infrastructure.
Key takeaways
- Municipal fire hydrants average 50 years in age, with some exceeding a century of service since 1910.
- Direct field assessment—counting actual installation dates—reveals a wider age distribution than industry surveys typically show.
- Broken and corroded parts appear regularly in hydrants around 40 years old, indicating many utilities operate equipment beyond its expected lifespan.
- The gap between what utilities estimate for their infrastructure and what field data reveals suggests widespread underestimation of the aging crisis.
