I published the draft performance standards for septic tanks and other domestic wastewater treatment systems for public consultation on 1 March 2012. The draft standards set out the responsibilities of owners of septic tanks and other on-site wastewater treatment systems, including requirements for the removal of sludge and ensuring the system is in working order and properly functioning. The public consultation process regarding the draft performance standards concluded on 30 March. In total 165 submissions were received. These are being assessed by my Department in consultation with the Environmental Protection Agency. When this assessment is completed, I will finalise the regulations which will give legal effect to the standards.
