Balannup Wastewater Pressure Main

Closed 24 Mar 2016

Opened 18 Mar 2016


In October 2014 the Water Corporation referred a proposal to construct and operate the Balannup Pressure Main, a 4.5 km wastewater pressure main from the Collared Street Pump Station to the Waterworks Road Pump Station in Armadale.  The proposal was subject to a 7 day public comment period which ran from 3 December 2014 to 9 December 2014. 

Since the referral of the proposal the EPA requested further information from the proponent regarding potential impacts in relation to the EPA’s objective for hydrological processes.  As a result the Water Corporation commissioned further work.  

Due to the public interest in the proposal and the time that has elapsed since the referral in October 2014, the new information is being made available for public comment.  A link to the original referral document is also provided.

What happens next

Following the seven day public comment period and consideration of any comments received, the EPA will decide whether or not this proposal requires environmental impact assessment and, if so, what level of assessment will be applied.

The Chairman's decisions on level of assessment are released each Monday on the EPA's website.
