Greater Sydney Desalination Program

Project: Greater Sydney Desalination Program
Client: WaterNSW
Role: Technical Advisor

Engaged by WaterNSW, Janson Projects played a pivotal role as technical advisor, assisting in the procurement of a consultancy to undertake preliminary engineering planning for seawater desalination plants in Greater Sydney. This initiative aimed to assess the feasibility and prepare for the potential development of desalination facilities as a climate-independent solution for bulk water supply to the region, contingent upon the continuation of drought conditions.

The consultancy's scope included:

  • Options Development Phase

  • Conducting feasibility studies

  • Power Purchasing Agreement (PPA) investigation

  • Preparing an options report, a preliminary environmental assessment, an overview report, and engaging in community and stakeholder consultation if required.

Key tasks included:

  • Identifying potential sites

  • Determining the optimal plant size and staging options

  • Assessing power supply and alternate power sources

  • Performing risk assessments and developing valuation criteria for options analysis

  • Conducting seawater quality monitoring and marine modelling

  • Creating generic concept designs and indicative cost estimates

  • Managing stakeholders and community relations

  • Undertaking necessary technical studies

  • Conducting financial and economic analysis of options

  • Environmental Assessment Phase

  • Preparing for the planning approval process for preferred options, including Environmental Impact Statements (EIS) for desalination infrastructure in the Illawarra and Sydney regions

  • Consulting with key stakeholders and undertaking public engagement if subsequent detailed planning was triggered

Under drought conditions. this phase was fast tracked, encompassing environmental planning investigations, approval pathways, environmental impact assessment studies, and, as required, stakeholder and community communication.

Janson Projects’ expertise ensured the successful procurement of a consultancy to deliver these critical preliminary studies, supporting the planning and potential implementation of sustainable water solutions for Greater Sydney.
