East Sabine Relief Sewer – Expansion of Sanitary Sewer System with FRP Pipes

14,400 ft (4,400 m)

Total Length

36 in (1,000 mm), 42 in (1,100 mm) & 60 in (1,600 mm)

Diameter

Pipe Length 40 ft (12 m)

Key feature

Construction was primarily completed using open-cut methods, while pipeline segments located in critical areas were installed inside steel casings to protect utility lines from potential damage caused by construction activities, natural elements, and soil movement. FRP pipes manufactured using the Continuous-Filament-Wound (CFW) process in multiple diameters – DN36, DN42 and DN60 (DN1000, DN1100, and DN1600) - were supplied with an FRP coupling pre-assembled on each pipe, facilitating installation on site.

A key feature of our supply on this project is the use of 40-foot long (12-meter) pipe sections. These extended lengths significantly reduce the number of joints, which not only enhances system reliability, but also streamlines the overall installation process. Fewer joints mean faster assembly, reduced labor time, and lower material costs, making the project more efficient and cost-effective from both a construction and long-term maintenance perspective.

A significant logistical achievement on this project was the timely delivery of a large volume of materials. The initial shipment was successfully delivered under 6 weeks from the receipt of the order, demonstrating strong coordination and supply chain efficiency. Subsequent deliveries for the remainder of the project were completed within an 8 to 10-week timeframe, ensuring a steady and reliable flow of materials to the site. This efficient delivery schedule was crucial to maintaining the overall project timeline, enabling continuous progress without costly delays or interruptions.

We’re proud to have contributed to support future growth in the area!

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

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

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.
