Integrated Water Cycle (IWC) Project
The Googong Township IWC Project will deliver a water cycle system that provides essential water and waste water services. It is an innovative response to the complex problem of water supply and has been designed to meet best practice water conservation outcomes.
The Googong Township IWC Project will be delivered in stages, which have been linked to the anticipated population growth. Some stages will require construction or decommissioning of temporary infrastructure so that service requirements can be met for the anticipated population.
This stage involves the infrastructure required to service the initial stage of the township subdivision, which mainly relates to the first of five neighbourhoods.
In subsequent stages of the IWC Project all key infrastructure elements would be expanded to their full capacity and interim or temporary elements decommissioned and replaced with permanent infrastructure.
Construction of Stage 1 of the IWC commenced in January 2013 and was completed on 05 July 2016. Stage 1 will delivered:
- A water recycling plant (WRP)
- Temporary reservoirs for recycled and potable water
- Pumping stations for sewage (SPS1 and SPS2), recycled (RWPS) and potable water (BWPS)
- Mains pipe work (including rising and distribution mains) for sewage, recycled water and potable to connect to Neighbourhood 1A (NH1A)
- Connection to the stormwater management system.
Stage 1 - stages and timing
Stage 1 was developed in three stages, Stage A - Network (west and east), Stage AB - WRP and Stage B - Network. See below for more detail.
|Stage||Description||Construction start date||Operation date|
|A – Network||
West: Construction of an interim water supply that includes potable and recycled water interim reservoirs, sewage pumping station (SPS1), connecting pipelines together with the connection to the subdivision reticulation network.
East: Construction of bulk water pumping station and connecting pipeline to service the interim reservoirs.
|AB – WRP||
Construction of Stage AB WRP to treat sewage and produce recycled water for use in the township.
|B – Network||
Construction of second part of the sewage network including a second pumping station and connecting pipeline.
There is concept approval for Stage 2 granted under Part 3A of the Environmental Planning and Assessment Act 1979 (EP&A Act), however project approvals will still need to be obtained by GTPL prior to commencing works on Stage 2.
Stage 2 will be delivered in two sub-stages in order to provide the appropriate infrastructure to accommodate the size and growth of the Googong township. Stage C is currently under development, with Stage D to be developed as demand requires in the future.
Stage C will be developed in three stages:
- Stage C - Network (West) - new potable water and recycled water reservoirs and supporting supply and distribution mains, decommissioning of the interim reservoir site, and the part of a rising main from the BWPS to the WRP. This stage has been approved by Queanbeyan City Council (now part of Queanbeyan-Palerang Regional Council (QPRC)) under Part 5 of the EP&A Act.
- Stage C - Network (East) - augmentation of the BWPS and rising main. This stage has been approved by Palerang Shire Council (now part of QPRC) under Part 4 of the EP&A Act.
- Stage C WRP - augmentation of the WRP. The process to obtain approval from QPRC under Part 5 of the EP&A Act is currently underway.
