Water and Sewerage Capital Contributions Code

The Water and Sewerage Capital Contribution (WSCC) Code formalises arrangements for contributions that developers pay towards future water and sewerage infrastructure upgrades for Class 2 assets that are necessitated by increased housing density in established suburbs (within precinct).  

Under the WSCC Code, the cost of water and sewerage infrastructure upgrades in established areas is shared between developers (when increasing housing density) and Icon Water. 

Prior to the WSCC Code being introduced, there was a “last man standing rule” whereby the single developer that triggered an upgrade for Class 2 assets was required to pay the full cost of new water and sewerage infrastructure. 

Capital contributions for developments within precinct (orange coloured areas on the precinct map) ensure that developers pay a share of the infrastructure costs necessary to accommodate population growth in established suburbs. This achieves two things: first, it ensures that existing customers are not disadvantaged (with higher costs or reduced amenity) by the connection of additional customers to the network; and second, it provides a price signal to prospective developers that is broadly reflective of the infrastructure costs associated with urban infill developments across the Territory. 
The current precinct charge for financial year 2022-23 is $1,094 per net increase in Equivalent Population (EP) that is within precinct. This charge is reviewed annually.  If you are not increasing the EP, you will not need to pay the precinct charge. If your development is not within precinct, you will not need to pay the precinct charge. 

The precinct charge that applies to a development is based on the lodgement date of the Development Application (DA). Applications lodged on or after 1 July 2022 will be calculated using the 2022-23 precinct charge of $1,094 per net increase in EP. Applications lodged prior to 1 July 2022 to 1 July 2021 will be calculated using the precinct charge that was in place at the time of DA lodgement.


  • How is the charge calculated?

    The charge applies to all developments that are located in precinct and increase the Equivalent Population (EP) on site. Refer to the Icon Water Precinct Map to determine if your development is within the highlighted precinct areas. The below calculator demonstrates how the charge is calculated.

    Are you in the highlighted precinct map area?

    Use the calculator to estimate the charge


    Please note: Additional charges for smaller water and sewerage assets still apply as per the Icon Water Miscellaneous Fees and Charges.

  • What do I need to do?

    1.When you submit an External Services Plan for In-Principle acceptance, we will identify whether your development falls into the scheme, and will write you a letter to confirm.

    2.When submitting your External Services Plan for Detail Design, we will verify the charge and write to you with an estimate of existing and new EP and your estimated charge.

    3.Let us know 90 days before your development is completed or requires connection to our network on 02 6248 3111 (option 3) or email wscc@iconwater.com.au. We will then send you an invoice for the WSCC charge, which needs to be paid before we can connect you to the water and sewerage networks.
