Our team develop an integrated water management plan for the Sydney Science Park within the Western Sydney Priority Growth Area providing strategic advice and conceptual design for an integrated water servicing strategy for a 288ha commercial, retail and residential precinct. Integrated WSUD approaches are proposed, including passive irrigation of streetscapes, flood mitigation and stormwater treatment within the riparian zone, stormwater reuse and wastewater recycling. Various options were considered with respect to aspirations to achieve no increase in downstream flow volumes to protect Science Creek as well as minimise the use of potable water within, and discharge of wastewater from, the precinct. Throughout the course of the project, five long-term servicing adaptive pathways were developed and assessed to understand the benefits and costs associated with each. A range of alternative water sources and demands were assessed against future growth in demand and climate conditions.
