Abstract

Failure to adequately address issues of wastewater treatment and disposal can lead to serious public health and environmental issues. However the cost of providing conventional sewerage collection and treatment facilities can be high and it may not be economically feasible, particularly in sparsely populated areas. In these circumstances, the onsite treatment of sewage is the logical alternative. Onsite sewage treatment systems are a common feature in most rural and urban fringe areas. In this regard, septic tank-subsurface effluent disposal systems are the most widespread due to their simple operation and maintenance procedures. However despite the seemingly low technology of these systems, failure is common and it can lead to significant adverse impacts. Therefore it is imperative that stringent compliance criteria and management practices are adopted in regards to their treatment performance and reliable strategies are taken to ensure householder compliance to these standards.

This research project constituted a field investigation undertaken in the Gold Coast City Council area on septic tank treatment performance and householder maintenance practices. Generally blackwater and greywater treatment is undertaken separately in the Gold Coast area. The current project focussed specifically on blackwater treatment systems. The study outcomes are expected to provide Gold Coast City Council with an informed overview of the current status of septic tank performance in its jurisdictional area. It is expected that this research will contribute to achieving the following primary objectives: • Provide a rational basis for strengthening regulatory strategies governing onsite sewage treatment in the Gold Coast City Council area. • Provide a specific focus for undertaking/strengthening public information strategies relating to septic tank operation and maintenance.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
