Students who have undertaken subjects such as Environmental Science, Water Studies, Environmental Chemistry, Water and Wastewater Treatment and Water Supply and Water Treatment may benefit from undertaking this subject.



A growing and resource-intensive global population has placed significant stress on the quality of our water resources. It is essential to minimise water pollution problems to maintain, or improve, our quality of life. With respect to water quality, the development of decentralised water and wastewater treatment systems are becoming more commonplace in unsewered parts of Australia and other countries in the world. Decentralised systems have many advantages compared to centralised systems, for some circumstances.

This subject introduces students to the differences in using centralised and decentralised systems and discusses different types of decentralised systems available for water supply and wastewater management for single households or small complexes of units. The subject introduces students to the different technical aspects and allows them to develop skills in the design and principles of these systems. This subject also looks at the overall management of water, from water supply to wastewater generation, treatment, and re-use on-site. One aspect of the subject is to look at the different types of systems available in Australia and to understand the water and wastewater technologies that are applied. This subject also covers the current environmental legislation related to decentralised wastewater treatment and disposal.

Students who are interested in solving problems in a sustainable manner and who have interests related to town planners, local council officials, small scale system operators, surveyors and architects gain knowledge on decentralised systems.
