Triangle Road pump station to boost water supply

We are bringing back into service a pump station to boost your water supply. Its purpose is to push water from our treatment plants to your area at a faster rate. This means we can keep your local water storage reservoirs topped up throughout the day more easily – including in summer when people use more water than normal.

While we are carrying out this essential work, water will flow through the pipes to your area at a faster rate which may stir up sediment in the pipes and discolour the water temporarily. In response, we will be flushing water through the pipes to remove the discoloured water. While we hope to have removed the discoloured water by Sunday morning, there may still be some in the network when you get up for the day. Please open the map to see the area that may be affected.

While discoloured water is not harmful to people’s health, we recommend you have bottled water available for drinking purposes for the morning of Sunday 10 December.

If you have discoloured water on the morning of Sunday 10 December, please run your tap for 10 minutes. If it does not clear, please let us know your address by emailing [email protected]. We will send a crew to your area to carry out further work.

Discoloured water may stain garments, so we recommend that you check the colour of the water during this period before you do a load of washing. If you experience discoloured water, delay doing any washing until it clears.

We expect any instances of discoloured water to be brief because our crews will be flushing the water pipes to push any discolouration that occurs out of the network.

If your household experienced discoloured water, once the water runs clear from the taps, it is safe to drink as normal.

If your household did not experience discoloured water, you can use water from the taps as usual.

Over time, harmless mineral deposits, such as iron and manganese, can build-up inside water pipes. These deposits tend to settle at the bottom of the pipes and remain there, undisturbed by the constant flow of water. When maintenance work is carried out that changes the direction or speed of water flow in the pipes, such as the commissioning of this pump station, the deposits can become disturbed. This sometimes results in discoloured water.

Discoloured water due to maintenance work on the water network does not contain any bacterial pathogens that could harm public health. The discolouration in such cases is caused by naturally occurring minerals.

We carry out frequent water quality tests at various locations across the Auckland region as required by the Ministry of Health to ensure that drinking water continues to meet health standards and remains safe to drink.
