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, with a flexible air supply conduit extending from each outlet to an elongated aerator. An end fitting is included in the aerator at each end. Each end fitting has a fastener defining an attachment location. A yoke is longer than the aerator and has two ends, one end fixed to each attachment location. The yoke also has a central yoke ring, which is loosely interfitted with a guide member to permnit 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. An upper end of the guide member is attached to a stop member, and a spacer is provided for positioning the aerator away from the stop member at the top of each guide member.
