The process and timelines for commercial and industrial developments and building of complexes are the same as residential connections, but the inclusions required for your application will depend on the type of activity that will occur on the site.

Depending on the type of activity, you may require:

  • upgraded connections
  • fire services
  • alterations to water and sewerage mains
  • some commercial activities will require backflow prevention and containment devices to protect the water supply from potential contamination
  • most commercial and service industries also require some form of pre-treatment, such as a grease arrestor which removes some of the grease and fats, before their liquid waste is allowed to enter our sewerage infrastructure
  • if you are constructing a multi-unit property, you may also need to install sub-meters for each unit. Approvals for sub-metering are handled through your development approval, but there will be an extra inspection required by Unitywater. Find out more about the sub-metering process and requirements.

5 phases of construction and development projects 

Commercial and industrial construction and development projects step through the following 5 phases. Projects without alterations or extensions to water or sewer mains skip the construction and handover phases which relate to the mains infrastructure. 

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 pre-lodgement meeting on site.

In this phase, you submit your documentation and plans for your connection and networks works approvals. The networks approval is only needed if you need to extend or modify the main. These two applications can be submitted together or one after the other. 

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

Once we have completed the assessment, we will send you our decision notice. Our decision notice is valid for 4 years.

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

Your development is ready to move into the construction phase

Developments that involve extension or modification of the mains will involve a construction phase in which you or your sub-contractors construct the new main.

The construction phase always starts with a pre-start meeting on site between you or your consulting engineer, your contractor (or principle contractor and sub-contractor) and a Unitywater inspector.

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.

Your development is ready to move to the live connection phase

All Developments will involve a live connection phase. It is in this phase that you must pay your ICN and receive your certificate of completion.

If your development did not involve network works, then the phase proceeds as below.

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

You request your certificate of completion
Your development enters the defect liability period
This is usually 12 months long. 

Only developments that involve network works will have this phase. This phase involves the final handover of the network assets and their maintenance to Unitywater.

After your defect liability period has ended you initiate this phase by submitting an off-maintenance request. This will prompt us to undertake a final inspection of the works. Once any defects are rectified, we release your bond and your development is complete.
