Safety comes first when working on or near our water and sewerage network. We coordinate all works to ensure safety of contractors and minimise impacts of service disruptions for our community.

We operate a Network Access Permit scheme which ensures that our Control Centre and our Customer Contact Centre understand planned activities being conducted on our network.

If you wish to carry out work on or near our assets, you will need to have a valid Network Access Permit and agree to our Terms and Conditions.

What is a Network Access Permit?

To undertake work on or near our network for a new water and wastewater connection, you will need to apply for a Network Access Permit (NAP).

To apply for a Network Access Permit, both the consultant and contractor are required to provide information for the Network Access Permit Application.

The Network Access Permit Guideline provides a detailed overview of all aspects of the process. 

How to lodge:

The Consultant is to access the Non-Standard application in the Developer Services Portal and complete the Network Access Permit application online. After receiving all fees, charges (including Infrastructure Charges) and required information, the approved Network Access Permit will be available in the Portal. Refer to the Network Access Permit Guidelines for processing times. 

Once you receive your permit, thoroughly review the approval conditions and guidance materials. Construction may now be undertaken in accordance with the timings and guidelines of your Network Access Permit.

The Network Access Permit request process has changed. Applications are now to be lodged via the Developer Services Portal.
Please refer to the Network Access Permit Guideline for an overview of all items needed as part of the request for a NAP. 

The following are some of the items required before a request for a NAP will be accepted:

  • a NAP application fee is payable upon lodgement of the request
  • contractor and meter installer details are required upfront
  • all metering information including serial numbers etc. are to be provided  and
  • Infrastructure Charges and any outstanding fees are payable before a NAP will be released. 

Each permit features general provisions, as well as conditions specific to your development and will advise if a shut plan or flow control plan is required.
Shut Plans are typically required for installation of a new hydrant, water main or service 100mm or larger in diameter. Every shut plan has a condition to undertake a trial shut.
Flow Control Plans are typically required if the existing sewer main or service is a rising main, pump or 160mm or larger in diameter.

We create shut plans based on as-constructed drawings available in our GIS system.

In some cases, this information may not be as current as your records, including engineering designs or first-hand site information.

If you are working on an old or brand new section of our network, we recommend you attach a mud map or mark-up of the design to your Network Access Permit application to help us create an accurate shut plan.

A condition on every shut plan is to undertake a trial valve shut. The benefits of a trial shut are that they:

  • ensure the shut plan is accurate and determine the exact number of impacted properties
  • provide the opportunity to resolve potential issues prior to time of construction, so you have no surprises on the day of connection. 

If you discover an issue with our network or a shut plan during the trial shut, we will investigate and trial a revised shut plan at no cost until an accurate plan is identified.


It’s your responsibility to:

  • Book one of our accredited valve operators, as no other companies are permitted to turn valves on our network. 
  • Provide three business days’ minimum notice to impacted properties. 
  • Engage with our Commercial Customer Team to assist in engaging any Critical Customer identified on the Shut Plan. This is a crucial step in the scheduling of your works. 

Your accredited valve operator can assist you with:

  • review of shut plans 
  • isolation services
  • trial shuts and valve audits
  • report trial findings
  • delivery of ‘water off’ notices.
