Waste Water Disposal Applications

All buildings that produce wastewater are required to connect to either the main sewer or an approved effluent disposal system.

Where main sewer is available it is a requirement for new buildings to connect, please contact the Water Corporation on 13 13 95 for information regarding main sewer connections.

Where main sewer it is not available an onsite effluent disposal system needs to be installed. There are a variety of effluent disposal systems available which range from standard septic tanks and leach drains to aerobic treatment units, known as ATUs. An application form is required to be completed in order for the Shire’s Health Service to assess the suitability of the proposed system for long term waste water disposal. The application must include two copies of a site plan showing the location of the building, boundaries, contours, contour levels and preferred location of the proposed system.

Wastewater Disposal Application Form

Once an application form has been received, an Environmental Health Officer conducts an onsite inspection to assess the suitability of the proposed system on the lot and to ensure that all requirements are met.

After a system is installed a final inspection is conducted to ensure the system has been installed in accordance with the conditions of approval. A permit to use is then issued providing the system complies and a Major Plumbing Compliance Certificate has been received from the plumber. It is an offence to occupy a house before a permit to use has been issued.

Applications for Conventional Septic Systems

In order to ensure the application addresses all requirements and to prevent any unnecessary delays in the approval process, please see the below Guidelines on Submitting a Septic Application.
