What we are doing

  • As you may know Downer, as part of SCIRT, is repairing the earthquake damaged wastewater system in Avonside.
  • On Thursday 15 December, we will be removing the bypass that we installed in October, and connecting the existing and new wastewater main to the wastewater chamber. While we work in the wastewater chamber, we will be using a pump to divert wastewater around the chamber that we will be working in.
  • Our work will take place at night between the hours of 7:00pm–7:00am, subject to favourable on-site and weather conditions.
  • We will be completing these repairs at night when flows in the wastewater pipe are minimal. This will ensure that the over pump can handle the diverted wastewater flow.

Work impacts

Downer, as part of SCIRT, will be taking a break over Christmas and New Year from Friday 23 December 2016 until Monday 9 January 2017.

We will deliver another work notice before this time to update you on our work.
