The Onsite Wastewater Management Plan 2025-2030 outlines Wyndham City Council’s approach to managing onsite wastewater systems in areas that are not connected to a reticulated sewer network. The plan helps protect public health, local waterways, groundwater, and the environment by ensuring wastewater is treated and managed appropriately.
The plan identifies local wastewater management challenges, assesses environmental and public health risks, and provides guidance for the design, installation, operation and maintenance of onsite wastewater systems. It also sets out actions to support sustainable development in unsewered areas across Wyndham.
