Septic tanks and wastewater management

How to apply to install or alter a septic tank system in an unsewered area, maintain the system and land capability assessments. 

On this page:

Non-sewered sites may require installation of wastewater treatment systems such as a septic tank including trenches for primary and/or secondary treatment to dispose of the wastewater generated onsite.

Options such as wastewater treatment plants and composting toilets are types of septic tank systems. A septic tank system treats and retains sewage (toilet water) and sullage (bath, shower and sink water etc.) within the boundaries of your property.

To install or alter a septic tank system in an unsewered area, property owners are required to apply for consent from the City.

Land Capability Assessments and septic tanks

A Land Capability Assessment is a report that assesses the viability of onsite wastewater management on a site where there is no reticulated sewerage.

It considers the risks that a wastewater system presents to public health, environment, and local amenity. It provides vital information on site-specific limitations for onsite wastewater management, as well as suitable management strategies to reduce impacts of the system on its surrounds.
