Back To ProjectsNarrogin, Western Australia

Water and Carbon Group were engaged by Water Corporation to design, construct and maintain a low energy waste water treatment solution to meet the increasing environmental constraints for the existing WWTP.

Narrogin WWTP project consists of design and construction of a treatment wetland that is used as the final treatment stage for the WWTP effluent prior to discharge to the environment. The following items were undertaken during the works:

  • Site clearing works
  • Bulk earthworks incorporating approximately 20,000m3 of cut to spoil and cut to fill including stringent compaction requirements
  • Site investigation works to support the finalisation of the design
  • Managing poor/unsuitable and variable ground conditions during the works
  • Pipework & maintenance shaft installation within the wetland berms and within extremely soft ground including DI, custom Stainless Steel and various PVC pipework
  • Installation of approximately 30,000m3 of Geosynethetic Clay Liner (GCL)
  • Topsoil placement using laser level machinery and low ground pressure to prevent damage to the GCL. Topsoil finished level tolerance +/- 25mm
  • Wetland planting (45,000 plants in 4 days)

CPM provided a Site Manager/Construction Engineer to manage and lead the construction of the project. This role was the sole representative in Western Australia for the majority of the project and required working autonomously and developing the required relationships with key subcontractors and the Client.
