What could be lurking in your pipes? 

Ragging Big 72dpi

Sometimes things end up in the wastewater system that shouldn’t be there.

‘Rag Monsters’ are made up of wet wipes, tampons, sanitary pads, nappies, cloth, hair and other non-biodegradable material, and they should never be flushed down the toilet.

They can block up wastewater pipes – which could cost you a lot of money in plumber bills to repair if the damage happens within your property boundary. If wet-wipes (or other items) manage to make it all the way to the wastewater treatment plant, they end up blocking the screens (which may have to be cleared by hand).

These items have no place in the wastewater system and should never be flushed down the toilet.

Put unflushable items into your rubbish bin, and only flush the 3Ps down the loo - pee, poo and paper (toilet paper that is)!


Consumer has investigated "flushable" wipes. Check out their story here.

‘Fatbergs’ are lumps of congealed fats, oils, and food waste washed down your sink. They grow larger as they pass through your home’s pipes.

These monstrosities love nothing more than hanging out until they are big enough to burst through pipes, causing wastewater overflows that can contaminate your home, the environment, or ruin important infrastructure.

These items have no place in the wastewater system and should never be poured down the sink. PUT FATS AND OILS IN THE BIN!

If you run a food outlet, ensure your trade waste treatment and certificates are up to date - contact info@wellingtonwater.co.nz if you need to know more.
