Balannup wastewater pressure main

back to current projects

Project goal:

Connect Collared St Pump Station to Waterworks Rd Pump Station

Status:

Commencing soon

Delivery Date:

To be confirmed

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

Water Corporation referred the Balannup Wastewater Pressure Main project to the Environmental Protection Authority (EPA) in October 2014. 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 Water Corporation’s 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 rel="noopener noreferrer" statement, or see the EPA’s determination.

On January 23, 2017, the Environmental Protection Authority announced it's recommended approval for the rel="noopener noreferrer" project. To review the EPA report please visit the EPA website.

On October 3, 2017, the Minister for Environment rel="noopener noreferrer" gain environmental approval for the proposal. Read the Ministerial Statement here.

We will continue to work with the community and stakeholders to deliver this important project.

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 2-week timeframe, ensuring negligible impact to fauna movements.   

Watch this video for a demonstration of the EcoPlough technology.
