Possible discoloured water and reduced pressure

Our customers in the suburbs of Bibra Lake, South Lake, Cockburn Central, Yangebup and Beeliar may be temporarily impacted by discolored water and reduced pressure from 5 February 2019.

Residents in parts of Bibra Lake, South Lake, Cockburn Central, Beeliar and Yangebup may experience temporary discoloured water from the evening of 5 February 2019 as a result of work we are completing with Main Roads WA as part of its Murdoch Drive Connection project.

Water supplies will not be interrupted; however customers may also experience a slight reduction in water pressure. Please be assured that the reduced pressure and discoloured water is temporary and should return to normal in the following days.

What causes discoloured water?

Discoloured water can occur at any time, but is most common in early spring and summer when our water use increases. Increased water flow through the pipes in summer can stir up sediment that has settled during winter, which leads to the discolouration. 

Is discoloured water safe to drink?

The sediment that causes discoloured water is harmless to health and the water is safe to use and drink. 

Where does the sediment come from?

Naturally occurring sediment can settle in pipes, where it can be stirred up by a sudden change in flow rate. The sediment is mainly comprised of very fine iron, manganese and clay particles.

What to do if you have discoloured water

  • Run the outside garden tap at the front of your property for a few minutes, until the water clears
  • Repeat the step above for an outside tap at the rear of your property.

If the discolouring persists, please call our 24-hour faults line on 13 13 75.

What if discoloured water stains my laundry?

Soak your laundry in water straight away. The staining caused by discoloured water is due to particles of sediment lodged in the fabric. The stain becomes permanent only if the laundry is allowed to dry.  You can request a cleaning powder kit to help remove staining by calling our 24-hour faults line on 13 13 75.

If you have any questions or special requirements please call our 24 hour faults and emergency line, 13 13 75.

We apologise for any inconvenience you may experience and thank you for your patience and understanding if temporary discoloured water does appear.
