Balannup wastewater pipeline

Installing a new wastewater pipeline and pump station upgrade in the City of Armadale

back to current projects

Project goal:

We are upgrading wastewater infrastructure to accommodate population growth.

Status:

In construction

Delivery Date:

Late 2019

What’s happening?

We’re constructing a below-ground wastewater pipeline and upgrading an existing pump station in the City of Armadale to cater for population growth. The infrastructure will provide services to the Balannup sewer area which includes the suburbs of Piara Waters, Harrisdale and Southern River.

The pipeline will start at Collared Street pump station in Harrisdale and continue on Keane and Hanlin Road to Waterworks Road pump station in Haynes.

Balannup

When is this happening?

Construction began in late March 2019 and will be completed in late 2019.

The work will be completed in stages and majority of work will be completed on weekdays between 7am and 5pm.

Our authorised contractor, Georgiou, will complete this work on our behalf.

How will this impact the community?

Pedestrian, bicycle and vehicle access to the Harrisdale Senior High School will be maintained at all times and we will endeavour to complete work during school holidays and weekends where possible.

This construction work will require a one-lane road closure in sections, and may result in some traffic congestion and delays. The crossing at Armadale Road and Tonkin Highway will use trenchless methods to minimise disruption to road users. We encourage drivers to plan ahead to seek alternative routes or allow for extra travel time.

Verge parking along the pipeline route may be temporarily unavailable, and pedestrian footpaths and access to a portion of Jim and Alma Baker Park may be restricted for short periods throughout construction for safety reasons. Temporary surfacing will be used to maintain access to any impacted driveways.

Our contractor, Georgiou, will be in contact with affected properties prior to construction including an offer for a dilapidation survey. We are committed to ensuring that any area impacted by our work, including home verges and driveways, will be returned as close to original condition as possible.

Who can I contact?

For enquiries specifically related to construction, please contact David Bradley, Georgiou Project Manager on 0447 805 001.

In October 2014 we referred the Balannup Wastewater Pressure Main project to the Environmental Protection Authority (EPA). At this time the EPA requested more information to enable them to set a level of assessment for the project. This was provided and the EPA re-advertised the proposal on in March 2016 for a further public comment period. 

In May 2016 the EPA announced it will formally assess our proposal and that the assessment is warranted at the level of an Assessment on Proponent Information: Category A (API: A). You can read the EPA’s statement, or see the EPA’s determination via their website.

On January 23, 2017, the Environmental Protection Authority announced its recommended approval for the relevant project. To review the EPA relevant report please visit the EPA website.

On October 3, 2017, the Minister for Environment gave environmental approval relevant for the proposal. For more information, read the Ministerial Statement

Construction methods

We are proposing to use an innovative trenchless construction technique to install the pressure main within the confines of Bush Forever Site 342. Application of this ploughing technique would allow the pressure main to be established:

  • in the confines of an existing firebreak, which is degraded and devoid of vegetation
  • without open-trench excavation and dewatering, which would expose Acid Sulphate Soils and trigger associated risks
  • within a short timeframe, ensuring negligible impact to fauna movements.
