South Australians are being taught to sing a song dedicated to their toilets.

Water supplier SA Water has launched a jingle it hopes with catch on and help stop the build-up of "fatbergs" in the state's sewerage.

Fatbergs build up in the pipes when people flush items such as wet wipes, condoms, tampons, pads and wrappers down the toilet.

Rather than break up, they stay in one piece, collecting other bits of detritus into a giant blockage.

While the size of South Australia's sewerage pipes means local "fatbergs" don't approach the monstrous mass of their London counterparts, they can still block and damage the system - as well as being thoroughly unpleasant to remove.

SA Water’s new campaign reminds people that only the "three P's" should ever be flushed - "paper, pee and poo".

And they're counting on an earworm of a tune to drive the message home - see below for the lyrics.

What goes in the loo

Paper, pee or poo

Your loo will thank you

And our sewers too

If it ain't the three P's

Put it in the bin please

And remember, just paper, pee or poo
