In 2026, municipalities and utilities nationwide face daily challenges associated with aging infrastructure systems that were installed half a century ago. These systems, while still serving essential functions, routinely operate well beyond their original design life.
Specifically, underground utility networks, water and wastewater facilities, and legacy gas and power assets frequently experience corrosion, through-wall failures, pinhole leaks, and localized degradation. However, even severe deterioration may not require full replacement. With budget restrictions and demand for continuous service, it is often better to repair with reliable solutions.
Carbon fiber composite repair systems are a proven repair option for these scenarios. For municipalities and utilities tasked with maintaining critical legacy systems under financial constraints, composite repairs offer a cost-effective and long-lasting solution.
Example Repairs for Gas Mains, Water Lines, and Piping for Municipalities and Utilities
Below is a compilation of projects within municipal utility networks and water treatment facilities where carbon fiber composite systems provided effective reinforcement without the cost and complexity of full asset replacement.
Advanced FRP Systems helped repair a 24-in natural gas main line in New York.
Emergency Reinforcement of Corroded Natural Gas Main – New YorkDuring a routine inspection, significant corrosion was identified on a 24-inch‑diameter natural gas main, forcing a temporary reduction in operating pressure. An emergency carbon fiber composite repair was applied to the area, reinforcing over more than 600 linear feet of pipe. The operator was able to restore the line to its original design parameters and protect it from further corrosion.
Leak Repair at Water Treatment Facility – New York CityA Y-shaped‑ pipe section outfitted with a mechanical clamp developed a leak while in service. Six layers of carbon fiber composite were applied to the entire affected section. The versatility of the wrap allowed the clamp to remain in place while delivering a permanent solution, avoiding operational disruption and expensive custom part replacements.
Advanced FRP Systems repaired a severe active leak in the basement of a water treatment plant in New York City.
Through-Wall Failure in Basement Piping – New York CityA rainwater transport pipe located in the basement of a water treatment plant experienced a through-‑wall failure that caused significant, “waterfall-like” leakage. A six-layer carbon fiber wrap was installed over the affected section, halting progression of the leak and eliminating the need for a complete pipe replacement.
High-Temperature Repair of Coke Oven Gas Bypass Line – OhioA coke oven gas bypass line suffered a through-‑wall failure at the elbow that worsened over time due to prolonged service and salt deposit accumulation. To avoid dangerous gases from escaping the line, a high-‑strength, high-temperature carbon fiber composite system was applied to create a structurally independent reinforcement capable of safely containing‑ the degraded host pipe.
Resource Round-Up
Advanced FRP has performed countless projects in municipal and utility applications. Along the way, we continuously publish content that showcases what we have learned. The resources below highlight selected projects and insights developed through close collaboration with our partners.
This featured project documents the rehabilitation of underground high-pressure, fluid-filled (HPFF) transmission lines serving a major urban area. Carbon fiber composite reinforcement was selected to address widespread external corrosion while keeping the system online. The repairs leveraged strategically spaced adhesion zones to reduce surface preparation requirements and deliver a long-term, maintenance-free solution.
Advanced FRP Systems consulted on a major repair effort for underground high-pressure, fluid-filled (HPFF) transmission lines.
This article examines the condition of underground high-pressure fluid-filled (HPFF) pipe-type cable systems throughout the U.S. Like most urban infrastructure in the country, these systems were installed primarily between the 1950s and 1970s and are now operating well beyond their intended service life. The article details how proactive rehabilitation using carbon fiber composite reinforcement offers utilities a practical, cost-conscious alternative to reactive emergency repairs or cost-prohibitive full system replacement.
The municipalities project collection highlights composite repair applications across water and wastewater treatment facilities, municipal piping systems, and structural assets. Facilities utilized high-strength carbon fiber composite solutions to effectively repair aging infrastructure. The projects include:
