Application process

The first step of the application process - the connection application and approval - provides an assessment of the entire development and proposed timing for each land release or stage. This step reserves network capacity for your project and allows the development to be considered in our demand assessments and future planning. The assessment time is 20 days - this can be fast tracked to 5 days.

You will also need approval for the proposed plan for your network construction. We call this network works approval and the assessment time is 20 days. You may submit the network works application for one or more of your stages at the same time as your connection application or at a later time. You are not able to start construction until you have network works approval.

The application process is complex and will require the support of experienced professionals. Before applying, we recommend requesting a Services Advice Notice, which allows us to consider your development proposal and preliminary layouts and provide suitable advice regarding the requirements of your application.   

Before you apply:

Multi-stage development projects can be complex and involved. We recommend you request a Services Advice Notice (SAN) before you start.

This is a free service we provide that will help ensure you are able submit a complete application and proceed quickly through the approvals process.

What you need to get started: 

The first step of your application is different to the subsequent applications and focuses on the 'connection approval' aspect of the development. Your first application will require the following documentation:

  • the land owner’s consent, plus the owner’s consent for any property affected by the proposed work e.g. adjoining land through which access may be required.
  • street plan that adequately locates the property for this connection
  • subdivision plan
  • development plan
  • network demand assessment.

For each subsequent application, you will need to submit additional documentation detailing the alterations, modifications or extension of the water and sewer mains network you propose to undertake for the stage(s) you are about to start. This includes:

  • network works design calculations
  • network works design drawings.


Supporting documentation

Depending on the complexity or the size of the proposed development, extra demand may be placed on Unitywater networks. Additional reports or documents may need to accompany the application. These include:

  • a supporting report on the proposed development
  • servicing strategies for the development
  • networks analysis reports
  • a subdivision development staging plan
  • a network staging plan.

Before applying, you’ll need to consider if approval is required to build or carry out work near Unitywater’s infrastructure.

5 phases of a subdivision project:

Each stage of your multi-stage residential sub-division project will step through the following 5 phases. Depending on how you execute your development project, different stages of your development may be in different phases. For example, stage 1 of your development project may be in the construction phase while you are still planning or getting approvals for stages 2 and 3. 

In the planning phase, you will be planning your development and preparing plans and documents to submit to council and Unitywater for approval.

We recommend that you request a Service Advice Notice (SAN) during this phase. The SAN is provided free by Unitywater and will help you submit a complete application and ensure your application is assessed in the shortest time possible. As part of the SAN service, you can also request a face-to-face meeting.

Services Advice Notice F9289 (PDF 140KB)

In this phase, you submit your documentation and plans for your overall development (connection approval) and then network works approvals for each stage of you development when you are ready to start them. If you plan to start construction on one or more of the stages of your development, then the network works approvals for these can be submitted together with the overall connection application.

During this phase, we may request additional information from you to help us to assess your application.

You submit your connection application

You can pay to fast track your connection application. This reduces the assessment time from 20 to 5 days.

You submit your network works application for this stage (when ready)
We may request further information (if needed)

Within 20 working days of receiving your complete application. Or 5 days for the connection application if it was fast tracked.

Unitywater sends you our decision notice for this stage

Within 20 working days of receiving your complete application or your response to our request for further information. Or 5 days for the connection application if it was fast tracked.

Unitywater sends you an infrastructure charges notice

Within 10 days of the decision notice.

This stage of your development is ready to commence. Move to the construction phase

Once we have completed the assessment, we will send you our decision notice. Our decision notice will detail how long it is valid for, this is typically 4 years.

You will also receive an infrastructure charges notice (ICN). This charge offsets the costs of ensuring that the extra demand your new sub-division places on our network is catered for. You do not have to pay this fee until you are ready to connect your new development or  infrastructure to the live network.

Once you have network works approval, you can move into the construction phase. The construction phase of each stage starts with a pre-start meeting on site between your consulting engineer, your contractor (or principal contractor and sub-contractor) and a Unitywater inspector.

You request a pre-start meeting
You start construction on the network works
You submit any variations for approval (if needed)

Minor variations will be approved by an inspector. Larger amendments will require approval by a Unitywater engineer. 

You may request a provisional certificate of completion (if desired)

This will only be possible once you reach a certain stage of completion and pay of an uncompleted works bond. Detailed requirements can be found in the Connection Administration Manual.

You finalise construction
Your development is ready to move to the live connection phase

During construction, you may need to request a variation to the approved plans. Minor variations, such as realigning a single section of water or sewer main or repositioning a hydrant or stop valve, can be approved on site by a Unitywater inspector. Larger amendments will need to be approved by a Unitywater engineer. The Connections Administration Manual provides full details.

If you wish to undertake an early release of your sub-division so that you can sell your blocks 'off the plan', then you can request a provisional certificate of completion once you have reached a minimum level of completion. Full details can be found in the Connections Administration Manual. In this case you will pay a higher bond than if you had waited for construction to be complete. In either case, your bond will be returned once you development is complete.

Each stage of your development will pass through a live connection phase. This is also referred to as the on-maintenance phase. It is in this phase that you must pay your ICN and you receive your Certificate of Completion for the stage. 

You submit an on-maintenance request for this stage
You pay a bond (if you haven’t paid an uncompleted works bond already)

This bond will be returned after you have successfully completed the maintenance period.

Unitywater inspects the works
If defects are found, you will need to rectify these and have the work re-inspected.
You pay your ICN
Unitywater establishes the live network connection for this stage
This is undertaken by our Private Works team.
You request your certificate of completion for the stage
Your development enters the maintenance period for the stage
This is usually 12 months long.

After receiving your certificate of completion and the network is live, you remain financially liable for any defects identified. The maintenance period is usually 12 months and ends when you pass on off-maintenance inspection.

Submit an on-maintenance request F9296 (PFD 210KB)

This phase involves the final handover of the network assets and their maintenance to Unitywater. For each stage, after the maintenance period has ended you can submit an off-maintenance request. This will prompt us to undertake a final inspection of the works for the stage. Once any defects are rectified, we return your bond and this stage of your development is complete. 

You submit an off-maintenance request for the stage
Unitywater inspects the work
If any defects are identified, you must remedy them and request a re-inspection.
Unitywater inspects and, if satisfied, returns your bond

A joint Off-Maintenance inspection will be held on the constructed site. The works shall be thoroughly inspection by the persons nominated below:

  • Consulting Engineer
  • Contractor (who completed the works), and
  • Unitywater Development Officer

The inspection will not proceed if either the Consulting Engineer or Contractor is not present. 

This stage of your development is complete.
