Ground Water

Ground Water

Ground water sources include bores and wells. You should seek advice before using these water sources, as they may not be suitable in your area.



  • Install water filters at your kitchen tap. Water filters remove a range of contaminants from the water, but you will need to choose the best type for you.
  • Maintain and replace your filters, following the manufacturer’s instructions. Neglected filters may release germs and chemicals into the water.
  • Clear running water is not always safe to drink. The risk of illness is low for most people. If you don’t want to take any chances, you can boil tank water used for drinking, cooking and washing food.
  • The risk is higher for people with lower immune response, such as very young children, older people, and people with a chronic illness. These people should always boil tank water used for drinking, cooking and washing food.


When and how to boil water


To be certain that your water is safe, you may choose to have your water tested. You can seek advice on collection, timing and the number of water samples from your local council. A fee may be charged for this service. 'One off' samples can be misleading.
