Responsible Waste Disposal

Responsible waste disposal


After assessing your Tradewaste application, Flow Systems will inform you by email, what trade waste pre treatment equipment, if any, is to be installed and inspected. Make sure you read our trade waste policies, practices and fees.

As a user of our sustainable water system, anything you put down the toilet, or sink comes back to our recycled water Centre. Learn about the dos and don’ts of your sustainable water network below.

If Flow Systems directs you to install tradewaste pretreatment equipment, you will need to buy and install this equipment from one of our authorised suppliers. Please find the name and number of our approved manufacturers and suppliers from one of the following lists:

  1. Bucket traps
  2. Grease traps
  3. Oil water separators
  4. Other pretreatment equipment

The installation of pretreatment equipment must meet Australian Standards, Workplace Health and Safety standards and Flow Systems guidelines. It must be installed by a registered plumber.

The installation of this equipment will be inspected by Flow Systems and if it does not meet these standards and guidelines it must be removed at the cost of the installer.

If you have another use for recycled water not listed on our website, please contact us and we can determine if its safe or not.

Remember all wastewater is collected onsite by our sustainable recycled water network. We convert this into the highest quality recycled water and send it back to your homes.

Your recycled water system is sensitive. What you put down the toilet, bathroom sink, laundry sink, kitchen sink and floor wastes affects the recycling process. Make sure you keep your sinks as healthy as possible.

Please avoid putting the following down your sink:

  • oils including cooking oil
  • milk
  • food solids
  • paint
  • pesticides
  • medicines
  • grease
  • chemicals
  • sanitary pads
  • tampons
  • condoms
  • nappies

If you have other items not listed on our website, please contact us and we can determine if it’s safe to dispose of or not.

Sink waste traps are easily installed in the kitchen and bathroom to help filter out inappropriate items.

Instead of flushing your waste down the sink or toilet, please follow our advice on how to get rid of waste.

  • Paints, chemicals, hazardous waste - please contact the City of Sydney, they run special chemical and e-waste drop-off days. They also collect larger amounts of refuse resulting from things such as house moves.
  • Food waste - you can start a compost or a worm farm to help turn your food waste into good quality soil. They are easy to set up and maintain, see below.
  • Nappy bins - there are lots of nappy bins available that can sanitise and store used nappies.
