Water mains flushing

Flushing of dead-end streets

Council contractors carry out flushing of the water-mains in dead-end streets, usually twice a year.  We advertise the streets affected in the local newspaper and on the radio.

After the water-main has been flushed in your street we recommended you run your front outside tap.  This is only a precaution to prevent possible rusty water from staining your washing.   

A water supply interruption

Our contractors Fulton Hogan will put a notice in your letterbox to let you know about a programmed water supply interruption. 

The notice will tell you the day and time the water supply is to be turned off for maintenance or repairs to the water supply system.

Things you may wish to do:

• store some water for general usage
• switch off the hot water cylinder or don't use your hot water
• turn off the taps to the automatic washing machine
• make sure there are no clothes or items in the sink in case a tap is left on accidentally
• turn your toby off at your boundary 
• once the water is back on, turn on the closest tap to your toby, let it run for a few minutes.

Problems you may experience when the water is back on

Milky white water

No health concerns, this is usually air trapped in the water.  Turn on a tap on for at least 5 minutes to run it clear. 
If the water is still milky after this  - contact us

Dirty or rusty water

Flushing of the mains has stirred up residue in the pipe. 
Turn your tap on for at least 5 minutes to run it clear.
If the water is still rusty - contact us

Plumbing or pressure problems

Toilet not refilling or water not running properly (low pressure).
An airlock or residue may have blocked part of the fillings.
Turn on your outside tap hard for a few minutes, if there is still no water - contact us
