Can a greywater system process blackwater?
Permanent greywater systems must not contain blackwater (water from a toilet or septic tank). The systems must also have the necessary Council permit (where required). A licensed plumber must make this installation. If they do contain blackwater they are not eligible for a rebate. Septic tank systems or upgrades to septic tank treatment systems are not eligible. Make sure you read all the terms and conditions on the back of the claim form for full details.
