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.

Stage 1

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 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.

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 in operation, with Stage D being developed as demand requires in the future.

Concept approval for Stage 2 was granted under Part 3A of the Environmental Planning and Assessment Act 1979 (EP&A Act). Subsequently, GTPL gained project approvals for Stage C and Stage D in April 2016 and August 2020 respectively.

Stage C was constructed and gifted to Queanbeyan Palerang Regional Council (QPRC) to operate. It currently provides water, wastewater and recycled water services for the first 9,400 residents in the Googong Township. Stage C is split as follows:

  • 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 was approved by Queanbeyan City Council (now part of QPRC) under Part 5 of the EP&A Act.
  • Stage C - Network (East) - augmentation of the BWPS and rising main. This stage was approved by Palerang Shire Council (now part of QPRC) under Part 4 of the EP&A Act.
  • Stage C WRP - augmentation of the WRP. This stage was approved by QPRC under Part 5 of the EP&A Act.
  • Stage D, the ultimate stage of the IWC, will provide water, wastewater and recycled water services to all of Googong Township. Stage D is split as follows:
  • Stage D Network – a third and final reservoir at the Nangi Pimble reservoir site and supporting supply and distribution mains.
  • Stage D SPS – pump upgrades to the 2 existing sewage pumping stations and 2 new sewage pumping stations (SPS3 and SPS4) Stage D WRP – augmentation of the WRP for greater operational capacity

Stage 2 - Stages and timing

Stage 2 will be developed in two sub-stages, Stage C (Network East, Network West and WRP) and Stage D. See below for more detail.

Stage Description Construction start date Operation date
C

Network East:

  • Augmentation of the BWPS and rising main.

Network West:

  • Construction of new potable water and recycled water reservoirs and supporting
  • Decommissioning of the interim reservoir site, and the part of a rising main from the BWPS to the WRP.

WRP:

  • Augmentation of the WRP for additional capacity.
