Illegal stormwater connections

It is illegal to connect your stormwater drainage to your sewer system as this increases the flow in our sewer network during wet weather and can lead to overflows in the environment

In the unlikely event of a sewer surcharge, your home's yard sink (often located on the outside wall of the kitchen or laundry) is designed to ensure the overflow occurs outside your home and not via your toilets and wash basins. Yard sinks are connected to the sewerage system and are not designed to collect any stormwater. It is illegal to connect or direct stormwater, including from down pipes into your yard sink.
