How does Hydrant Renewal rebuild fire hydrants up to 75 years old with integrated technology?
Mueller Water Products' Hydrant Renewal program completely rebuilds fire hydrants that are up to 75 years old, integrating acoustic leak detection technology into the system. When multiple acoustic nodes are deployed across the water distribution network, they can pinpoint leaks within a few feet, giving utilities precise guidance on exactly where to dig.
Turning Decades-Old Equipment Into Smart Infrastructure
Rather than replacing aging fire hydrants entirely, the Hydrant Renewal program extends the life of infrastructure that municipalities have already invested in. The complete rebuild process restores structural integrity while simultaneously introducing modern monitoring capabilities that the original equipment never had.
As outlined in this episode of the Empowering Industry Podcast, fire hydrants surveyed in the field demonstrate why this approach matters—the average age of hydrants in typical distribution systems hovers around 50 years, with some installations dating back to 1910. By this stage, corrosion and broken components become systemic issues, but the Hydrant Renewal program offers a practical alternative to wholesale replacement.
Acoustic Leak Detection: Precision Technology in Action
The technology integration centers on leak detection capabilities deployed as acoustic monitoring nodes. These can be attached as a specialized nozzle cap on the hydrant or seamlessly integrated into the bonnet itself, depending on the system design and utility preferences.
The real power emerges when multiple acoustic nodes work together across a water distribution system. A network of these sensors can triangulate and pinpoint leaks within a few feet, transforming leak response from guesswork into precision. Instead of utilities digging exploratory trenches or relying on surface indicators, they receive exact coordinates for where underground breaks or seeps have occurred.
Paul Gifford, who leads product management at Mueller Water Products and draws on decades of engineering experience in the valve and hydrant industry, explains how this technology addresses a longstanding operational pain point in the full podcast episode.

Paul started his engineering career at a valve and hydrant company in Elmira, New York, working in the foundry, product development, and quality. He has since returned to the hydrant and valve industry after a circuitous career path, now based in Chattanooga, Tennessee at Mueller Water Products, where he identifies market opportunities and develops innovative solutions like the Hydrant Renewal program. His daughter also works as an engineer at Mueller Water Products.

Key takeaways
- The Hydrant Renewal program extends the operational life of fire hydrants up to 75 years old through complete structural rebuild, eliminating the need for wholesale replacement.
- Acoustic leak detection nodes can be integrated into renewed hydrants as either a specialized nozzle cap or seamlessly into the bonnet, adding modern monitoring to legacy infrastructure.
- When deployed as a network, acoustic sensors pinpoint water leaks to within a few feet, enabling utilities to dig with precision rather than conducting exploratory excavation.
- Field evidence shows that hydrants around 40 years old routinely exhibit broken and corroded components, making the rebuild approach both economical and practical for aging distribution systems.
