Whether you have an onsite sewerage system, septic tank and trench or are connected to town sewerage, fats/oils/grease (FOGs) poured down the house drains and into these systems can cause costly repairs and maintenance. FOGs will solidify once cooled down and will clog drains and pipes. Whether you have your own sewerage system or are connected to town sewer, the maintenance and repairs will cost you directly (hiring someone to fix your own personal system) or indirectly (rates for a town connected sewer)
An aerated system, as indicated by the name, blows air through the system to help with the breakdown of waste matter. This aeration when mixed with FOGs, can create 'fat balls' (see pic) which can then lead to blockages. Not all FOGs will be caught up into a ball so there will still be liquid fat filling up the pipes, decanter, irrigation and moving parts.
What can we do with our FOGs?
> Pour cooking oils, fats and grease into a container that can be sealed and place the sealed container into the rubbish bin for collection
> Wipe out frypans, saucepans and cooking utensils with paper towel and place paper towel in bin (paper towel is designed to not break down easily and can cause blockages itself)
> Don't put food scraps down the kitchen sink as the FOGs are not removed from the food (insinkerators are not recommended for onsite sewerage systems). Recycle scraps into compost or place in bin
What is the accepted matter that can be flushed into the drains?
> Bodily waste and toilet paper - only!
What does not go down the kitchen sink, toilet, waste drains of our dwelling?
> Paper towel, cotton buds, baby/adult wipes, feminine hygiene products, contraception products and other foreign matter. These should all be disposed of through general waste collection
