Hi All, Just wondering if there is any drainage expert on the forum who could shed some light on this issue: I'm considering buying a lovely property in QLD which has a backyard on higher ground than the house. Being in QLD I'm a bit fearful of water/the rain getting into the house as it is on lower ground and not sure if its worth the risk. The agency says there is a “gully trap” behind the house where all the water coming from the higher ground is diverted into. This gully trap is connected to the storm water drain system which also diverts the rainwater from the roof to the front street. Is this sufficient ? Is there a solution which can be used to prevent water from flooding into the house ? Image of the backyard is attached. Any suggestion much appreciated.
