Septic tanks and wastewater management

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.
