Field Reports

ISCO Supplies and Supports Record-Breaking Project for Wastewater Treatment Plant Piping

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. ISCO Industries supplied the 2250 mm pipe manufactured by Agru America in 16-meter sticks.
