Petrie WSZ Distribution Network Analysis


Moreton Bay, Queensland

Scope of Services
The Petrie Water Treatment Plant (WTP) is a major facility providing bulk treated water to approximately 100,000 people within the Petrie Water Supply Zone (WSZ). The Petrie WTP is an aging facility and previous subregional planning undertaken by Seqwater identified potential significant whole-of-life benefits in decommissioning the plant and connecting the Petrie WSZ to the broader bulk water supply network. Engeny was engaged to undertake detailed hydraulic modelling to review the impacts to the Petrie WSZ distribution network with the decommissioning of the Petrie WTP, including:

  • the impacts of changes to the system demand across existing and future planning horizons
  • firefighting capabilities
  • opportunities for external connections and potential rezoning.
