Wastewater Collection & Storage
Glycol is widely used at Calgary International Airport for aircraft de-icing.
While some of the glycol is recycled, during heavy rainfall, glycol-contaminated stormwater is ﬂushed into the City of Calgary’s sanitary sewer system. Seeking a more sustainable solution for its new International Terminal Building, the Calgary Airport Authority decided to collect and treat glycol-contaminated stormwater onsite.
Employing a two-stage biological process, the facility is one of the most advanced systems for treating glycol. Associated Engineering, in collaboration with Nexom and Thurber Engineering, helped complete this $28.7 million project in less than 11 months, on time for the International Terminal Building’s opening in 2016.
