Remember to only flush the 3Ps - pee, poo and (toilet) paper – anything else can result in blockages in our wastewater system.

Wet wipes, kitchen paper towel, tissues, cotton buds, toothbrushes and toys are just some of the things that make their way into our wastewater system.

Our wastewater system is designed to take away toilet paper and human waste, so when other items end up in wastewater pipes, they can not only cause blockages at your property but also problems for the broader wastewater system. If the blockage or overflow is on your property, you will need to engage a licensed plumber and are responsible for any repair costs.

It’s up to all of us to take care of our wastewater system and avoid blockages.

All toilet cleaning and shower products are safe to use without affecting our wastewater system.

We have put together some safe disposal tips to help you do your bit to reduce wastewater blockages.

Wet wipes and toilet paper alternatives

It’s important to remember that only the 3P's should be flushed down the toilet - Pee, Poo and toilet Paper!

Wet wipes may be labelled as ‘flushable' but they don’t disintegrate like toilet paper – so they should not be flushed down the toilet. In addition, tissues and paper towel are not made to break up the way toilet paper does, so they can also contribute to blockages.

Follow our safe disposal tips

Our safe disposal tips will help you ensure that you avoid any wastewater blockages – or damage to your kitchen or bathroom.

Tissue and paper towels - These aren't made to break up the way toilet paper does, so they can end up clogging your pipes or the sewer system.

Nappies, menstrual products (napkins and tampons), razors, cotton buds, syringes - Please wrap these up and put them in the bin.

Cooking fats and oils - Around 30% of blockages in our wastewater system are caused by fats, oils and grease solidifying in pipes.

To avoid this:

  • Remove grease and food scraps from your pots, pans and dishes before you wash them

  • Seal kitchen grease into a container and place it in the bin

  • Use a strainer in your kitchen sink to ensure these things don't get into the wastewater system.

Chemicals and oils - This includes things like paint, cleaning products, fertiliser, pesticides or oils. None of these should go down the drain. Instead, give these to a licensed hazardous wastes contractor or contact your local council to see if they have hazardous waste drop offs at the local tip.

Engine oils - Take this to your local garage or oil recycling centre. Alternatively you can contact your local tip for advice on the best way to dispose of the oil.

Food scraps, coffee grounds, tea leaves - Remember to put these in the bin or compost.

Newspapers and plastics - It's much better to recycle these kinds of items.

Unused medicines - You can return these to your pharmacy for safe disposal.

Top Toilet Tips!

  • Have a bin in the bathroom, so that nobody's tempted to flush anything other than toilet paper
  • Wipes, tissues, paper towels, cotton wool, buds, menstrual products, nappies and even wipes that claim to be “flushable” can create blockages so don't flush them down the toilet.

This fun experiment will help kids learn about how different paper types which seem similar don’t break down in the water like toilet paper does.
