Important note about sub-metering of existing buildings and complexes 

  1. It is possible to install (retrofit) individual water meters, rather than having one main water meter, to existing buildings or unit complexes.

  2. The body corporate must approve and apply for this retrofit on behalf of the owners. A copy of the body corporate minutes approving the retrofit of sub-meters must accompany the application.

  3. This will be at the cost of the owners or the body corporate.

  4. Unitywater advises that a private plumbing contractor should be consulted in regards to the feasibility of retrofitting sub-meters to an existing building. There may be cost associated with the plumbing installation/augmentation that will need consideration.

  5. Body corporates can view the process, fact sheets and application forms in the kit below.

  6. Once you are ready to proceed, your plumber can find all the information they need in the sub-metering for plumbers section.

What you need to do:

  1. If you are planning to construct a new multi-residential complex or building, you will need approval from your local council.

  2. Units and townhouse 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 to submit a complete application and proceed quickly through the approvals process. 

  3. You will also need to get Unitywater approval for the installation of a sub-metered network on your property and its connection to our network.

  4. Your plumber is responsible for installing the meters, but Unitywater will inspect them before providing a certificate of completion.

  5. If the water and fire service needs of your development can’t be met by your current water meter, you will need to request that Unitywater increase the size of your meter. Your hydraulic engineer will be able to tell whether this is needed. The meter upgrade can be requested as part of the initial connection application.

  6. Before completion you will also be asked to pay an infrastructure charge. This charge offsets the cost of ensuring that the extra demand the multiple dwellings place on our network is catered for.

What you need to get started: 

To submit your application for connection of a residential sub-metered property, you will need:

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

If your development requires work on the water or sewerage mains you will also need:

  • network works design calculations
  • network works design drawings
  • networks analysis reports for water and sewerage
  • lowest lifecycle costing report (desirable, but not required).

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