Abstract
On-site wastewater disposal systems have been adopted in small communities for many years. There are several types of systems, such as pan service (PS), pump-out septic tank (POST), conventional septic tank system (CSTS) and the more recently introduced aerated wastewater treatment system (AWTS). Examination of the extensive application of PS, POST and CSTS over the last few decades has highlighted several problems associated with these systems. Currently, AWTS is being widely used throughout Australia, particularly in unsewered suburban areas where installation and maintenance are controlled by local councils or municipalities. AWTS consists of primary and secondary tanks or compartments. The secondary tank or compartment in turn consists of aeration, secondary settling and disinfection/irrigation chambers. This paper discusses the design considerations for each of the above compartments/chambers of AWTS and comments on the results of a brief survey of field performance.
