Water quality problems

There are many reasons why your water may suddenly taste, smell or look different. 

Generally there are three common water quality problems that you may experience:

  • colour
  • taste and smell
  • effect on soap and saucepans when washing
  • Yellow to rusty-brown water or rusty stains on washing

    Causes can include

    • Rusting galvanised iron pipes on property.
    • Ageing galvanised iron pipes within properties are a common cause of discoloured water and an unpleasant taste.
    • Choked with rust, they can also drastically reduce water pressure. The best solution is to replace the old pipes with new copper or plastic pipes.
    • Stains on washing may be due to rusting iron pipes but they can also be caused by other factors, e.g. fabric softeners.

    Turn a tap on full for a few minutes. If the water clears, the colour or sediment probably results from rusting galvanised iron pipes on your property.

  • Small particles in the water supply system

    This can be caused by rusting pipes or from the natural sediments in our pipes.

    If you cannot clear the water by turning a tap on full for a few minutes, the problem probably lies outside your property with the water supply system. This can become a particular problem with courts and dead-end streets.

    In most cases such problems only persist for a short time. If not, contact us on 13 2762 for assistance.

  • Water with a blue or green tinge

    This is a complex problem which can be caused by corroding copper pipes on property. Please contact us on 13 2762 for advice.

  • White, cloudy or milky water

    This can be caused by air in the water and cannot do you any harm. Water can also become aerated in the hot water service. To determine if there is air in the water, hold a glass of cold water to the light and you will see tiny bubbles start to clear from the bottom.

    Cloudy water (not air bubbles) can be due to corroding copper pipes.

    Aerated water cannot do you any harm, but if the problem persists please contact us on 13 2762.

  • Brackish, metallic or stale taste

    This can be caused by:

    • Rusting galvanised iron pipes on property.
    • Ageing galvanised iron pipes within properties are a common cause of unpleasant taste.
    • Choked with rust, they can also drastically reduce water pressure. The best solution is to replace the old pipes with new copper or plastic pipes.

    Turn a tap on full for a few minutes. If the taste disappears, it probably results from rusting galvanised iron pipes on your property. Please contact us on 13 2762 for help in determining the exact cause.

  • Slight smell of chlorine

    Mild chlorination is an essential part of the process of purifying water, but just occasionally the chlorine taste is noticeable. If you do smell chlorine, we can usually take steps to improve the situation. Please call us on 13 2762.

  • Poor lathering of soap

    The presence of calcium in water affects soap and various saucepans. Calcium is leached from new cement lined mains and occurs most often in new subdivisions.

    In time the pipes will stabilise, but if you have a continuing problem, please call us on 13 2762.
