Project Element 5: Upgrade Sewer Infrastructure

The proposed sewerage infrastructure upgrade as shown in figure 8. The new gravity and rising mains will replace the sewerage network where they are currently deficient in capacity, condition and compliance.

This will include a new pump station adjacent to the separate hardstand proposed by the Facilities to Support Naval Operations in the North project to capture and discharge the sewerage from the new wharf facilities. This will divert the localised systems within HMAS Coonawarra to discharge into this new pump station.
