ISCO Industries and Largest Solid-wall HDPE Outfall in North America

The needs of the new McLoughlin Point Wastewater Treatment Plant in Victoria, British Columbia presented an opportunity that would lead to the construction of the largest solid-wall HDPE outfall in North America.

The line stretched 1.92 km (1.2 miles) long and was primarily constructed with 2250 mm DR26 HDPE pipe. It featured several unique and innovative concepts from design to installation. High-performance HDPE pipe manufactured to European ISO standards was the material of choice. ISCO Industries supplied the 2250 mm pipe manufactured by Agru America in 16-metre sticks. HDPE was selected based on its long-term performance in the corrosive seawater environment, seismic resiliency, and its ease of construction.

An assembly site was set up in Nanoose Bay, north of Nanaimo, about 180 km by sea from the project site. A weather-resistant enclosure was set up around the ISCO supplied fusion machine. Sections of pipe were trucked to the site where experienced ISCO fusion technicians were able to complete three fusions per day for a total of more than 100 fused joints. This project was an incredible demonstration of teamwork between multiple entities resulting in a record-breaking installation. The construction showcased what can be accomplished with ISCO and HDPE pipe.
