# Modernizing Montreal’s West Island Potable Water Network with FRP Pipes
The project features the installation of 36 in (900 mm) FRP pipes manufactured by SUPERLIT, engineered for a minimum nominal pressure of 150 psi and using the restrained joint system with Full Face® FRP couplings. This solution ensures the system's leak-tightness, corrosion resistance, and installation flexibility. Over 60 custom fittings were designed and manufactured to accommodate the project layout. Complying with NSF/ANSI 61, ASTM D3517, and BNQ certification, the project contributes to a sustainable and resilient drinking water system for the West Island community of Montreal.

Solution
Carried out in close collaboration with the City of Montreal and the contractor, this project aims to modernize a critical section of the West Island’s water and sewer infrastructure. Divided into three phases (Phase A: 2024/2025, Phase B: 2025, Phase C: 2024/2025), it leverages Novinfra’s expertise to deliver a sustainable, high-performance, and resilient infrastructure solution for the community.
The project involves the installation of 24-inch (600 mm) and 36-inch (900 mm) FRP pipes manufactured by SUPERLIT, designed for a minimum nominal pressure of 150 psi. The pipes are assembled using the Full Face® restrained joint system, which consists of FRP sleeves with EPDM sealing gaskets covering the full surface if the coupling and locking keys. Specifically engineered for pressurized applications, this system ensures long-term leak tightness and installation flexibility, allowing up to 3° of deflection depending on the pipe diameter.
The installation also includes more than 60 custom-made FRP fittings, along with five valve chambers and eight drain chambers, all designed to withstand a minimum pressure of 150 psi. Choosing an entirely FRP system provides complete corrosion resistance, simplified maintenance, and maximum durability for the city’s underground infrastructure.
A major factor behind the project’s success was the preparation of detailed installation plans, enabling each stage of construction to be executed with precision while minimizing disruptions and optimizing space in urban and residential environments. The ability to perform in-situ adjustments of FRP pipes and FRP fittings also contributed in optimizing the contractor’s performance and flexibility in meeting the project schedule.
From a logistics standpoint, the project required 40 deliveries totaling 64 containers of materials and several air shipments. Thanks to strategically located storage facilities in the Montreal area, part of the deliveries were managed offsite. This approach helped optimize operations in densely populated zones, reduce congestion, and ensure continuous supply to the construction site.
Despite the project's complexity, the collaboration with the City of Montreal was exemplary. Through open communication and regular coordination meetings, the teams were able to anticipate challenges and maintain a proactive, solutions-oriented approach throughout the project.
We are proud to have contributed to building a more resilient and sustainable drinking water system for the West Island community of Montréal!

#### [Structural rehabilitation of Culvert in Trois-Rivieres using Channeline FRP liners](https://novinfra.com/blog/structural-rehabilitation-of-culvert-in-trois-rivieres-using-channeline-frp-liners)
After an inspection revealed significant structural deficiencies that required the immediate closure of the road for safety reasons, Channeline FRP liner system was selected to restore traffic and extend the structure’s service life of the existing culvert - a sustainable, structural solution custom-designed to fit the existing culvert’s shape while minimizing excavation and disruption. Prefabricated with precision in arch-shaped segments, the Channeline FRP liners were rapidly installed by sliplining through a single access point, enabling efficient work execution despite challenging site conditions. The new FRP structure increased the culvert’s hydraulic capacity by nearly 8%.

#### [East Sabine Relief Sewer – Expansion of Sanitary Sewer System with FRP Pipes](https://novinfra.com/blog/east-sabine-relief-sewer-royse-city-texaseast-sabine-relief-sewer-royse-city-texaseast-sabine-relief-sewer-royse-city-texas)
The East Sabine Relief Sewer project in Royse City, TX, is a major wastewater infrastructure upgrade designed to expand the city’s sanitary sewer system. Superlit FRP pipes will contribute to increase capacity, enhance reliability, and mitigate potential issues related to the city’s rapid growth, which has placed increasing demands on the existing infrastructure. The new sanitary sewer will be operated by the North Texas Municipal Water District.

#### [Red Oak Creek Relief Interceptor](https://novinfra.com/blog/red-oak-creek-regional-wastewater-system)
This project featured the installation of approximately 8,720 linear feet of 27- to 30-inch (700 to 800mm) Superlit FRP gravity sewer pipe. Each section was joined using Full Face® FRP couplings, ensuring a leak-free, corrosion-resistant, and flexible joint system capable of accommodating minor angular deflections. Installation combined open-cut excavation and tunneling, with FRP pipes installed inside steel casings in sensitive areas to minimize surface disruption.
