Pro Line’s UV-CIPP liner for potable water is specifically designed for the structural rehabilitation of pressurised drinking water pipelines. Built with certified materials and advanced GRP (Glass Reinforced Plastic) technology, this liner guarantees the safe, hygienic, and long-lasting performance required for potable water systems. Its precision-engineered construction ensures it meets or exceeds the highest industry standards for water quality, pressure resistance, and long-term durability
Pro Line’s potable water liner is manufactured using materials that are fully compliant with international drinking water standards, including those governing hygiene, toxicity, and long-term water contact. Each component is independently tested and approved to meet strict regulatory requirements, ensuring safety for end users and full compatibility with potable water systems. As a proven UV-CIPP technology already in use across global networks, Pro Line offers water utilities a trusted, hygienic, and regulation-compliant solution for rehabilitating critical drinking water infrastructure.
Pro Line’s potable liner is a fully structural rehabilitation system, capable of restoring the mechanical strength and flow capacity of deteriorated host pipes without reliance on the original structure. Designed in accordance with international standards for pressure-rated liners, it provides stand-alone performance even in severely degraded pipes. This ensures long-term asset renewal and extends service life by decades—without the need for excavation or full pipe replacement.
Engineered to perform under pressure, Pro Line’s UV-CIPP liner is suitable for use in potable mains, rising mains, and other pressurised systems where structural integrity is critical. The liner’s composite structure is designed to withstand both continuous internal pressure and short-term surge loads without deformation or failure. This makes it a reliable solution for protecting vital water supply lines and maintaining system performance in high-demand environments.
Pro Line’s potable water liner is widely recognised across the UV-CIPP industry for its ease of installation and contractor-friendly design. Lightweight, flexible, and smooth to handle, it is especially well-suited for confined spaces or complex site conditions where precision and efficiency matter most. Its advanced UV-curing system enables rapid installation with minimal downtime, helping to reduce labour demands, streamline project delivery and minimise disruption to surrounding communities. For contractors and asset owners alike this means lower installation costs and a faster recommissioning of the asset.
Inner Foil
Multi Layer barrier that remains inside the liner after the curing process.
Fibreglass Composite Layer
Fibreglass impregnated with styrene free Vinyl Ester resin
Outer Fleece Layer
Layer that encapsulates resin and protects during transport and installation process. Layer also prevents resin leakage.
Outer Foil with UV protective film
Multi-layer composite film provides protection against exposure to external factors during installation such as to light and early curing.
Outer film with UV protective film
Multi-layer composite film, with polystyrene layer and bonded on light protection film, protects against external effects during transport and installation. Also prevents resin leakage, exposure to light and premature, unwanted curing.

Is UV-CIPP lining safe for drinking water?
Yes. Pro Line’s UV-CIPP liners are manufactured using materials certified to international drinking water standards. Each component is rigorously tested to ensure hygiene, non-toxicity, and are 4020 approved /certified making them safe for use in drinking water systems.
Can potable water relining be used in both residential and commercial systems?
Yes, Pro Lines potable UV-CIPP liners are suitable for both residential and commercial water systems, offering a reliable and non-disruptive installation method ranging from DN100>
What is the Design Life / Service Life for a Potable Water UV-CIPP liner?
Pro Line’s potable water liners are engineered for a 100-year service life, backed by third-party testing and certifications. This makes them a reliable long-term investment for water utilities and municipalities focused on sustainable infrastructure.
What is the maximum length of potable liner that can be installed in a single day?
The maximum length of potable liner that can be installed in a day depends on pipe size, environmental conditions, and equipment used, but typically up to 300 meters can be installed and cured each day.
What is a UV-CIPP liner for potable water and how does it work?
A UV-CIPP liner for potable water is a trenchless solution used to rehabilitate pressurised drinking water pipelines without excavation. Pro Lines drinking water approved liner is inserted into the existing pipe and cured with UV light to create a strong, seamless barrier. This process restores both structural performance and water safety with minimal disruption.
Is UV-CIPP installation safe for high-pressure systems?
Yes. Pro Line’s liners are manufactured and installed under strict quality controls. During curing, pressure monitoring systems are used to ensure uniform curing and liner expansion, resulting in a safe, reliable solution for pressurised systems.
