The Fish Creek Wastewater Treatment Facility is one of 2 wastewater treatment facilities. Along with the Bonnybrook Wastewater Treatment Plant, the two plants can treat more than 577,000 cubic meters of wastewater every day. The treated water from the facility is released into the Bow River.

Excerpt from City of Calgary document at
(visit link)

"Calgary is the largest city in Alberta, Canada, with a 2006 population exceeding 1,000,000. The City of Calgary
owns and operates two municipal wastewater treatment plants, Bonnybrook and Fish Creek, to provide
treatment to Calgary wastewater prior to its discharge to the Bow River (Exhibit 1). The Bonnybrook Plant is a
biological nutrient removal tertiary treatment plant with a design capacity of 500 ML/d (Exhibit 2). The Fish
Creek Plant is an oxygen activated sludge treatment plant with a design capacity of 72 ML/d (Exhibit 3). Both
primary and secondary sludges are produced at the two treatment plants. After undergoing adequate treatment
with the anaerobic digestion process, digested sludges are regularly pumped to the off-site Shepard Sludge
Lagoons for storage and gravity settling to separate sludge solids from the clear supernatant. The Shepard
supernatant is continuously returned to the Bonnybrook Plant as a recycle flow."

What is the capacity of the facility?: 72,000 cubic meters per day Describe the biological treatment technology used.: Bioreactors - These large open-air tanks mix Primary Effluent with a high concentration of naturally occurring microbes. These micro-organisms eat the dissolved nutrients (phosphorous and ammonia) and organic material to help them reproduce. Compressed air is injected near the bottoms of the aeration tanks and bioreactors. Oxygen in the air is used by the micro-organisms in their life processes. The injected air also mixes the micro-organisms and brings them into contact with the organic materials. This biological treatment process is called the air-activated sludge process. The mixture of activated sludge and primary effluent is known as mixed liquor. After a seven-hour average retention time, the mixed liquor flows to the secondary clarifiers. How are biosolids (sludge) managed?: Sold to farmers as fertilizer and soil conditioner What technology is used for disinfection prior to dicharge of treated water?: Ultra Violet radiation Who is the owner/operator fo the facility?: City of Calgary What is the website of the WWTP?: [Web Link] How is the facility governed?: Not listed

Please post at least 2 original photographs of the site. We would much rather see photos of the plant itself as opposed to the front office, but we also understand that security and site layout may limit your opportunities.
