Water quality issues

Water quality issues

Brown, dirty or discoloured water

Brown, dirty or discoloured water is often associated with maintenance work but may also be related to internal plumbing.

What to do:

If your water is dirty/discoloured from maintenance work, simply run your tap for a few minutes after the works are completed to let the clear water come through.

If the water does not clear, please contact council on 1300 MACKAY (622 529).

If you have an internal plumbing issue, i.e. corrosion of the pipes, please contact a licensed plumber to investigate.

Water that has a brown tinge to it, is still safe to drink, as the colour change is due to elevated concentrations of iron and manganese.

Cloudy water

Cloudy water is often caused by air in the pipes and is not harmful in any way.

This can happen during the flushing of mains and the operation of hot water units or aerators on taps.

What to do:

Simply fill-up a glass or container with water and allow it to sit for 10 minutes. The water should clear as soon as the bubbles rise to the top and settle.

If the water does not clear, please contact council on 1300 MACKAY (622 529).

Blue or green coloured water

Blue or green discoloured water is usually caused by corrosion of household cooper pipes.

It may also occur in new houses with new copper pipes and it will reduce overtime.

What to do:

In the short term, flush the affected tap for two minutes. This clears the water in the affected pipes.

To fix the problem contact a licensed plumber to inspect your pipes for corrosion and replace them if required.

Odour/taste

If you believe your water has a strong odour or taste, please contact council on 1300 MACKAY (622 529) and complete a customer request.

Odour/taste enquiries are investigated individually.

Water pressure

During normal operating periods, water will be provided to the meter at a pressure of 22m of head (220kPA), and a rate of 20L/min.

Properties that are part of a Tank Replenishment Scheme are subject to different water pressures.

What to do:

If you believe your water pressure is low, please contact council on 1300 MACKAY (622 529) so council can investigate.

Pressure testing will be carried out to determine the problem. Water pressure issues could be caused by water meter problems, internal plumbing issues or blockages within water meters or mains.

The quality of our H2O

Mackay Regional Council’s water is rigorously tested by our Water and Waste Scientific and Analytical Services Laboratory.

Many tests are performed on both our raw and potable water supplies to ensure it meets the National Health and Medical Research Council’s Australian Drinking Water Guidelines.

Water from our Nebo Road Water Treatment Plant was voted Queensland’s best tasting tap water in 2018 and water from the Marian Water Treatment Plant was voted best tasting Water in Queensland and Australia in 2019.

Our laboratory also offers a variety of water testing suites to the general public including testing water tanks, bores and irrigation systems.
