An aeration system for a wastewater treatment plant includes an air supply pipe for receiving compressed air. The air supply pipe has a plurality of outlets. A flexible air supply conduit extends from each outlet to an elongate aerator having ends. An end fitting is connected to the aerator at each end thereof, with walls in each end fitting defining an attachment location. A guide member is provided for each end fitting, each guide member having lower and upper ends, and the guide member being loosely interfitted with the attachment location of the end fitting to permit relative movement between the aerator and guide member. The lower end of the guide member is fixed with respect to the bottom of the wastewater treatment basin. The upper end of the guide member is attached to a stop member. A spacer for each end of the aerator is provided, the spacer having upper and lower ends, and the upper end contacting the stop member and the lower end contacting the aerator end fitting, such that the aerator is positioned away from the stop members by the spacers at each end, with the aerator being repositionable by removing the spacers from the guide members or by changing the length of the spacers.
