Remove unwanted water.

Why drainage is important for a healthy home

Without proper drainage, water can pool up around your home and cause problems. A build up of water under a house can weaken the foundations, compromising the structural integrity of the home. It can also cause the growth of mould and mildew, while stagnant water outside the home makes the perfect breeding ground for mosquitoes. Effective drainage removes storm water, surface water and ground water from the property, keeping the foundations safe from harm and the residents safe from illness.

How you can use drainage to make your home healthier

Poor drainage can lead to flooding, property damage and health hazards - none of which are particularly desireable. Properties are required by law have efficient drainage for the removal of storm water, surface water and ground water, including an appropriate outfall. The drainage system must include gutters, downpipes and drains for the removal of water from the roof.

What you need to know


Properties must have effective drainage to protect people and other property from the negative effects of surface, storm and ground water, ensuing it is disposed of effectively and cannot enter the building.


Preventing unnecessary build-ups of water is important for a healthy home. By installing a good drainage system you allow water to flow freely, preventing the accumulations that lead to pooling or flooding.


Landlords are required to have a efficient drainage from the removal of storm water, surface water and ground water, including an appropriate outfall. Ensure you talk to your landlord about any concerns you might have, and report any drainage issues you notice as soon as you can.
