If you’ve been thinking about installing a composting toilet lately, it’s likely you’ve thought to yourself “I wonder if it’s against the law to install a composting toilet?”. Well, we’ve tried to answer all your questions and more below.
Before we get into the legalities of installing composting toilets we wanted to cover an important aspect of composting toilet design and that is if they meet Australian standards.
Composting Toilets and Australian Standards
The first thing you will want to make sure of is that any composting toilet you look at meets Australian standards. The Australian standard you want to look for is the AS1546.2.
This particular standard is part of a series that’s been revised for both Australia and New Zealand for on-site domestic wastewater management.
These standards test plastic tank materials, injection moulding methods and rotationally moulded tanks so when you’re checking out composting toilets online or talking to a composting toilet manufacturer, make sure you ask them about AS1546.2. Standards and if their products meet them.
Composting toilet – Australian State Legislation
When it comes to composting toilets essentially your local council has the final say on what you can and can not do however it’s worth knowing what the state laws say as many local councils will defer to the Australian Standards and State Legislation for guidance when it comes to the type, size and placement of a composting toilet for residential use. Let’s go over our state laws.
Queensland laws for composting toilets
The Department of Housing and Public Works states that as long as the composting toilet you purchase complies with Schedule 8, Part 2 of the Environmental Protection (Waste Management) Regulation 2000, you’re good to go.
They also recommend getting a written statement of compliance from the manufacturer or distributor. If you require this for one of our products, please let us know as we would be more than happy to organise this for you.
