Associated Engineering was appointed by the Alberta Capital Region Wastewater Commission (ACRWC) in April 2008 to provide engineering services for the expansion of facilities at their Wastewater Treatment Plant (WWTP) near Fort Saskatchewan, Alberta. The expansion of the plant is part of a combined project with an industrial client who will take tertiary treated effluent from the plant for beneficial re-use.

The ACRWC WWTP is located on the North Saskatchewan River between Fort Saskatchewan and Edmonton. The plant serves communities surrounding Edmonton, including Spruce Grove, Stony Plain, St. Albert, Fort Saskatchewan, Strathcona County, Bon Accord, Gibbons, Morinville, Parkland County, and Sturgeon County, as well as the north-east section of Edmonton and industries, including Air Products, Agrium, and Sherritt.

The existing WWTP has the capacity to treat a peak flow of 140 million litres per day. Treatment includes biological nutrient removal and ultraviolet disinfection prior to the discharge of flows to the North Saskatchewan River.

The current project includes two new secondary clarifiers, tertiary disk filters, and a new ultraviolet disinfection plant. The capacity of the plant will increase to 210 million litres per day. The total capital value of the project is estimated at over $40 million.

Associated Engineering has an established working relationship with the ACRWC, including previous expansions and upgrading at the WWTP. For this project, Associated Engineering has been engaged to provide overall project management, pre-design, detailed design, and general and resident engineering services during construction and commissioning.

Project Manager, Graham Lang, advises, “Pre-design was completed in September 2008 and detailed design work is now progressing, with construction tenders scheduled for early 2009. Construction work is due for completion at the end of 2010.”

The Associated Engineering project team is led by Graham Lang as Project Manager, Pat Given as Design Manager, and Brad Elliott as Construction Manager, supported by design teams in the Edmonton, Calgary, and Burnaby offices.
