In Progress


  • Protection of the environment, specifically the water quality in the River Maine and Castlemaine Harbour
  • Legal compliance, as the quality of treated effluent will comply with regulatory requirements and Castlemaine’s EPA authorisation
  • Capacity for future growth, as the plant will provide wastewater treatment for future growth in Castlemaine and can be expanded further in future if required


  • All of the necessary approvals and legal permissions are in place, and we have begun work on the WwTP site.
  • Works in the N70 are now complete.

What is involved?

  1. Build a new wastewater treatment plant at Castlemaine. The plant will serve a population of 750 people, and can be further expanded at a later date if required
  2. Build a new pumping station with storm water storage.
  3. Replace over 660m of sewer pipe
  4. Build a new inlet pumping station and storm water storage at the outfall to the River Maine
  5. Install pumping and a refurbished header manhole at the outfall to the River Maine
