⁠⁠⁠Port Augusta City Council invites tenders from Tenderers for the provision of Septic Tank Pump-Out and Disposal of Associated Sludge/Bio Solids. The Council will enter into a Contract for Services from 1 March 2021 to 30 June 2023 with the successful Tenderer.

Community Waste Management Schemes (CWMS), are systems for the collection and management of wastewater generated within a town, regional area or community not connected to SA Water sewerage infrastructure.

Port Augusta Council has a number of CWMS throughout Port Augusta and Stirling North.

As part of the efficient operation of the CWMS systems, Council runs a four (4) yearly septic tank desludging program for the safe and effective disposal of associated bio-solids. The four year program includes all properties within the Local Government Area with a septic tank system installed and connected to a CMWS. This equates to a total of approximately 1,550 septic tanks.

All property owners connected to the scheme pay an annual CWMS service charge (as part of their rates), meaning the cost is met by Council to pump out and dispose of bio-solids from residents septic tanks.
