Our wastewater treatment process involves many steps and different pieces of equipment, and the full tertiary treatment process can take 17 to 18 hours. See what it takes to treat wastewater in Edmonton.
Pre-treatment protects plant equipment by removing large pieces or materials that would otherwise create wear and tear on the plant while also improving quality of organic solids (which play an important part in later treatment).
Primary treatment consists of gravity-settling aided by a rake mechanism.
During wet weather periods the combined sewers often capture more runoff than they can handle, resulting in wastewater overflow to the river.
Solids go to the fermenters and digesters for treatment to create “biosolids” which can be re-used as fertilizer.
Microorganisms digest nitrogen and phosphorus in the water and then settle out in the clarifiers to clean the water further.
Check out a detailed explanation of Gold Bar's treatment process.
Cleaning the water further (polish & disinfect.)
A small portion of treated wastewater is diverted for membrane filtration.
Before being returned to the North Saskatchewan River after almost 18 hours of treatment, the clear wastewater effluent is disinfected by high intensity ultra-violet light.
Our Gold Bar commitments
Edmonton is one of Canada's largest Class IV wastewater treatment plants (class level indicates how complex the plant's operations are). The Gold Bar Wastewater Treatment Plant is ISO 14001 and OHSAS 18001 certified. Every day Gold Bar produces treated water that consistently surpasses regulatory standards.
As part of our latest long term plan for Gold Bar we've committed to keeping Gold Bar's operations within the current fenceline. Learn more.
The Edmonton plant utilizes innovative processes that reduce our environmental impact including membrane-based wastewater recycling facility which supplies local industry with reclaimed water. We also recover approximately $200K in annual fuel savings by utilizing biogas produced on site.
We're continually investing in new ways to control odours at Gold Bar minimizing our impact on the surrounding community. Learn more about recent odour improvements.
Each day an average of 265 million litres flow through the Edmonton WWTP with the full tertiary treatment process taking 17-18 hours from start to finish, but the plant's current design can treat up to 310 million litres per day. Some other capacity figures include:
Gold Bar also provides biosolids to farmers and has distributed close to 550,000 dry tonnes of biosolids to over 16,000 hectares of farmland since 1978. The biosolids program is available to Edmonton-area farmers. Additionally, more than 180,000 dry tonnes of biosolids have been made into compost products for sale since 2000.
Facilities to support the BNR upgrade component include primary sludge fermenters; sludge blend tanks; Waste Activate Sludge (WAS) thickeners; two new bioreactors/clarifiers; and a new 3,500 horse power blower.
