Balannup wastewater pressure main

Proposed wastewater pressure main for the Balannup Sewer District.

back to current projects

Project goal:

Connect Collared St Pump Station to Waterworks Rd Pump Station

Status:

Commencing soon

Delivery Date:

End of 2019

What’s happening?

We are building a new wastewater pressure main in the Balannup Sewer District to connect to new assets that have been built to accommodate growth. 

This requires the development of a 4.5km wastewater pressure main to connect the Collared Street Pump Station in Harrisdale to the Waterworks Road Pump Station in Haynes. The new main will cater for growth in the area.

Project approvals

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 it's 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

    EcoPlough demonstration

    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.   

    Watch this video for a demonstration of the EcoPlough technology.
