Water Distribution

Water Distribution

​Delivering Water to Your Home

Once river water has been treated to all health and safety standards and is ready for human consumption a gravity-fed system is used to distribute water throughout the water supply area.

Water always moves towards the lowest point, so we are very lucky here in Coffs Harbour to live on a low coastal plain with high mountains behind us. This topography enables water reservoirs on top of the high mountains and allow nature to do the work of moving the water down the hill from the reservoir to your house. The higher up the hill towards the reservoir your property is, the lower your water pressure will be. If your property is at the very bottom of the hill, you will have the very highest water pressure.

In fact, Council uses Red Hill Reservoir to slow down the drinking water coming from the Karangi DAFF Treatment Plant into Coffs Harbour, as the water pressure created by water coming straight from the top of Red Hill into town could be too much and might even blow some water distribution mains out of the ground! You can see the Red Hill Reservoir next time you drive west of Coffs Harbour on Coramba Road - it's the big round, silver corrugated iron roof on the left hand side of Red Hill before you pass the quarry.

Coramba and Nana Glen are also classified as gravity-fed water supply systems.

 

  
Description
  

​To obtain a Static Pressure test or Fire Flow Pressure test you will need to submit a completed Water Pressure Reading Application Form and pay the Water Pressure Reading fee.

  

​You can find a map of the water distribution network in the Coffs Harbour LGA here.

  

​Sometimes, Council will need to shut off the water flow to a section of our water main network to allow our staff to complete emergency repair works, scheduled maintenance or improvement works to the water distribution system.

Depending on the water mains in the area, the water supply interruption could affect residents in just one small cul-de sac street or an entire village or area.

Wherever possible, Council will make every effort to avoid or minimise any inconvenience to residents.

Before the water is turned off

In cases of scheduled water main maintenance or improvement works, Council will give those residents likely to be affected by the water supply interruption written notification 24 hours in advance of the water being turned off.

In cases of unplanned water main or water service repair works, Council is unable to give any notice to those residents likely to be affected by the water supply interruption that the water is going to be turned off.

After the water is turned back on

Council will flush the water mains in the area after the scheduled maintenance, improvement works or emergency repair work is completed in an effort to ensure clean drinking water is available to residents, however affected residents may experience some issues with the water supply:

  • Dirty water - dirt particles can get into the water main during the works process, which can make the water in your house appear brown or coloured. You can turn on the tap at your water meter and run water out of the tap until the water runs clear. You may also need to run the taps in your house until the water runs clear from those as well.  If the dirty water problem persists, please contact Council.

  • Milky/cloudy water - air can make it's way into the water main during the repair works, which can make the water in your house appear white or milky. If you pour a glass of water and sit the glass on a table for a few minutes, you will see that the water starts to clear from the bottom up - as the tiny air bubbles make their way to the surface. If you leave the glass long enough, eventually all the the air bubbles will dissipate and the whole glass of water will look clear again. These air bubbles have no adverse health effects on drinking water quality.

The same as for dirty water, you can turn on the tap at your water meter and run water out of the tap until the water runs clear. You can also run the taps in your house until the water runs clear from those as well.

Air in the water mains should clear quickly, but if the problem persists at your property, please contact Council 02 6648 4000.
