Wastewater Disposal (Grey & Blackwater)

All disposal and treatment systems must be approved by the Department of Health WA.

It is required that an application form be submitted to the Council, along with suitable plans and fee prior to any works taking place. See link below.

The fee for typical installations is listed on page 5 of the application. The application will require two copies each of a site plan and floor plan showing all plumbing details. For those developments that are a second or more dwelling on a single lot or a commercial development producing more than 540L per day of effluent (waste water), the fee is payable to the Shire of Narrogin with an additional $35 payable to the Chief Health Officer.

Once an application has been received, it will be assessed to ensure it complies with relevant legislation. A site visit will also be made to the property prior to approval being granted to ensure the soil type is suitable and to ascertain the geography of the property to ensure there is adequate fall for the drainage.

Subject to works being completed in accordance with the approval, a permit to use will be issued.

Failing to submit an application, beginning work on the construction of a system prior to approval to construct being granted, or using a system prior to it being given its final approval may all be dealt with by prosecution.
