The Parkland area west of Edmonton, was experiencing population growth that the ACRWC predicted would overload the existing 750 mm (30 inch) diameter sewer line servicing the area. Consequently, the organization embarked on a plan to expand sewage transmission capacity by twinning the existing sewer line with a 1350 mm (54 inch) diameter line. After reviewing their options, the ACRWC awarded IPEX the contract to supply 920 meters of 1350 mm (54 inch) diameter and 2300 meters of 1200 mm (48 inch) diameter SDR 35 Ring-Tite® PVC gravity sewer pipe.
