Overview and Contact Us

South Wallsed Water Supply


Hunter Water is providing a water reticulation scheme to approximately 165 properties within the Williamtown Contamination Investigation Area, as defined by the NSW Environment Protection Authority (EPA). The scheme will provide access to safe drinking water for properties which include residential lots, a primary school, a commercial area and tourism facilities. Hunter Water will provide one connection per existing residential dwelling or commercial development.

Planning for this project has commenced, and construction will be complete before 30 June 2017.

The cost to deliver this scheme is $3.5Million.

If you are interested in connecting to the water supply network please see the 'Maps' section and identify your property. If you are not able to identify your property please contact Hunter Water for assistance.

Properties outside of the Investigation Area

Hunter Water is providing access to safe drinking water to properties inside the Williamtown Contamination Investigation Area, as defined by the NSW Environment Protection Authority (EPA). Properties outside of the Investigation Area cannot be connected to the water supply as part of this funded project.

Property owners outside the Investigation Area have the option of funding their own connection to the water supply. The cost to the property owner will vary depending upon the proximity of an existing suitable water main and other factors. More than 12kms of new water mains are being installed as part of this project, bringing access to Hunter Water's supply closer to many properties.

If you are interested in connecting your property which is outside the Investigation Area there is a six step process.

Step 1: Apply for a water main extension

Apply to Hunter Water for the extension of water mains using our standard 'Application for Developer Services' form.

Step 2: Hunter Water will investigate your application

Each water main application is unique. Factors to be considered include:

  1. Does the property have access to an existing water main, or is a new water main or water main extension required? If connection to an existing water main is possible, and the original installation of that water main was paid for by a developer, new connections to that main may need to pay a contribution to that developer.
  2. How will a new service affect the existing water supply system?

Step 3: Receive a Notice of Requirements letter

Hunter Water will forward a 'Notice of Requirements' letter you. This Notice will detail what you are required to do in order for the water connection to be provided to you.

The requirements for your application may include:

  1. Design and construct water infrastructure specified in the notice necessary to serve your property.
  2. Transfer of the infrastructure to Hunter Water.

You will be required to engage an accredited design consultant to assist with meeting our design and construction requirements (as detailed in our Land Development Manual).

You may be required to prepare a Review of Environmental Factors (REF) to assess the likely impacts an activity may have on the environment. Before commencing the preparation of a REF, you should consult with Hunter Water to discuss your requirements.

Step 4: We Issue an approval letter

Once you have met these requirements Hunter Water will forward a letter of confirmation.

Step 5: Install new water infrastructure

You will need to engage a contractor to install the required water infrastructure to enable the connection.

Step 6: Arrange for connection

You can then arrange connection to the water system at a Hunter Water Customer Centre. Water connection fees are also paid at a Customer Centre.

Watermain Construction

Watermain Construction Update

Construction of watermains and infrastructure in the Salt Ash area will begin on 9 January 2017 and be completed by mid-April 2017. Work will involve establishing a site compound near Paul's Corner, installation of pressure-reducing valves and equipment near the corner of Nelson Bay Road and Oakfield Lane, and construction of approximately 10kms of new watermains along Nelson Bay Road and residential streets in Salt Ash.

Construction will occur at up to five locations simultaneously. Approximately 100 metres of new watermain will be installed each day, and revegetation and restoral of each area will occur shortly after.

A Traffic Management Plan has been developed to ensure the safety of pedestrians and motorists near construction sites and the site compound. The Plan takes into consideration holiday traffic and vehicle movements within the school zone during school hours in 2017.

Hunter Water has appointed Eire Construction Pty Ltd to complete this work. If you live or own a business near where construction will be occurring, a representative from Eire Construction will contact you to explain the construction process and address any concerns you may have.

During construction, management and handling of soil and groundwater will be in accordance with the approved Project Management Plan.

If you have any questions or concerns about the work on-site please call Hunter Water on 1300 657 657. For after-hours emergencies call 1300 657 000.
