Onsite Wastewater Control Systems
An onsite wastewater treatment system is a means of disposing of your effluent when there is no sewer available. If you are required to have an on-site wastewater system, the type of system best suited to your needs and the capabilities of your site will need to be designed by a consulting wastewater engineer, with regard to a soil testing report.
New wastewater systems or alterations to existing systems will need to obtain approval from Council. An application form must be completed, submitted with the appropriate accompaniments to Whyalla City Council and then approved prior to the commencement of any work.
