Water main renewals

As the water main system ages and deteriorates, we replace pipes to ensure you have a reliable water supply.

We normally upgrade a section at a time (approximately 200 metres), and try to minimise the impact on customers, as well as on other services, and the environment .

If there is a water main renewal planned for your area, this is what you can expect.

Before we start

  • Temporary pipe in the streetWe will write to you a few days before we start work.
  • In some cases, we will install a temporary water supply above ground, via a blue hose. Ramps will be placed to allow vehicles to drive over these pipes. It is a good idea to let the contractor know if you need this altered for any reason.
  • Please make sure your water meter is accessible as we may need to connect your property to the temporary water supply.

While we're replacing the water main

  • There will be noise but it usually will be restricted to normal working hours, Monday to Friday between 7am and 5pm. 
  • Construction work in streetThere will be pipes, machinery, building materials (such as gravel), a storage container and work trucks in the street and nature strip.
  • Traffic control will be in place, and we'll do our best to minimise disruptions to local traffic.
  • There will be holes in the nature strip, covered with boards so we know where other services are located in the ground such as gas, so our workers are safe and other services aren’t disrupted.
  • As we upgrade the main, we may also replace or move hydrants in your street to provide better access for firefighting services or make the system work more efficiently.

Water will be turned off to connect to the new pipe

Even when a temporary water supply is installed, at some point we need to turn off the water for a few hours to connect the old pipe to the new pipe.  Typically, we do this during business hours to minimise the disruption to customers.  We’ll also make arrangements with businesses, but it is worth making contact with us to discuss how your business will be affected.

You will receive one week's notice of any planned water interruption.  If something unexpected occurs such as the temporary water supply is damaged, we cannot give you advance warning.  If this happens we will work as fast as we can to get the water back on.

Restoring your area when the pipe has been replaced

  • Our first priority is to make the area safe. We will temporarily patch any holes we make in the road or driveway, until we come back to permanently restore the area. 
  • We will replace the topsoil and reseed the nature strip if we had to dig it up to replace the water main. Please avoid parking on nature strips to allow grass to grow.
  • Around three weeks after replacing the pipe, our contractor will be back to permanently repair driveways, roads and footpaths – this time is required to allows surfaces to settle.
  • If you see a temporarily patch road, footpath or nature strip that’s become unsafe, please call us on 13 2762.
