Join us for an educational luncheon on the Mill Creek combined sewer trunk, which conveys wastewater and rainwater from south Edmonton to the Gold Bar Wastewater Treatment Plant, built in 1958.

The Mill Creek combined sewer trunk, which conveys wastewater and rainwater from south Edmonton to the Gold Bar Wastewater Treatment Plant, was built in 1958. The service area for this trunk is about 8,200 Ha plus the Nisku & Leduc areas. According to the Multi-Sensor Inspection (MSI) in 2018 and the concept study, the physical condition of the trunk is poor and very poor, especially the section found in Mill Creek Ravine. This trunk was determined to be a high priority rehabilitation project. The main scope includes 890m of 2100mm diameter new tunnel with two shafts, 200m of local sewer reconnection, and abandonment of 860m of existing trunk.

The first phase of the project construction was a micro tunnel which began in March 2023 and was successfully completed in June 2024. This included the construction of a secant pile working shaft next to the Mill Creek School playground, a liner plate retrieval shaft within Tubby Bateman Park, and an HDPE lined 2100mm inside diameter (ID) reinforced concrete jacking pipe installed by micro tunnel boring machine (MTBM).
