On-site Wastewater

If your property is not connected to the Council’s reticulated town sewer system, you will need or may already have an On-Site Sewage Management (OSSM) system.

On-site Wastewater Investigations, provided by Caldera Environmental provide options for wastewater disposal, infiltration and remediation options within your property boundary to be Council compliant with your development. This includes wastewater relating to both black-water (toilet) and grey-water (bathroom, laundry, and kitchen).

With guidance on how to install and managed correctly by our team, an OSSM can provide efficient storage and treatment of your household wastewater, ensuring environmental safety and compliance with local regulations.
