As municipalities face aging infrastructure challenges, ultraviolet light-cured glass-reinforced pipe (UV GRP) technology has emerged as a game-changing solution for pipeline rehabilitation. In an exclusive panel discussion at WWETT 2025, Roy Barnes, deputy director of Georgia’s Fulton County Public Works Water Reclamation Department, highlighted the compelling benefits of UV GRP liners.

Structural superiority

With a background in mechanical engineering, Barnes was particularly impressed by the performance specifications of UV GRP liners. Some of these innovative liners, like Reline America’s Alphaliner, boast flexural modulus values that range between 1.66 million and 3 million psi. This exceptional strength ensures long-lasting structural integrity, even under demanding conditions.

Efficiency and speed

One of the most significant advantages of UV GRP liners is the streamlined installation process. Unlike traditional felt liners that require heat or steam curing, UV GRP liners are pulled into place, inflated, and then cured using UV light. The rapid installation process helps to minimize downtime and reduce disruption to communities.

Versatility and standardization

The flexibility of UV GRP technology allows for rehabilitation across a wide range of pipe sizes and shapes. This versatility has led Fulton County to standardize on UV liners for most rehabilitation projects, except in cases of extremely complex pipe geometries.

Environmental and cost benefits

UV GRP liners have a smaller footprint compared to traditional repair methods. They require less energy for installation and minimize excavation, reducing overall project costs and environmental impact. The improved flow capacity due to the smooth interior surface of UV GRP liners also contributes to long-term operational efficiency.

Quality control and longevity

The UV curing process enables precise control during installation, ensuring uniform curing and consistent quality. This attention to detail, combined with the inherent strength of the materials, results in a rehabilitation solution with an expected lifespan of 50 years or more.

A smart investment for municipal infrastructure

As municipalities grapple with aging infrastructure and limited budgets, UV GRP liners offer a compelling solution. The combination of structural strength, rapid installation, and long-term durability makes UV GRP technology an attractive option for forward-thinking public works departments. By embracing this innovative approach, municipalities can efficiently rehabilitate their pipeline systems, enjoying reliable service for decades to come while minimizing costs and community disruption.
