Boulder Bay Wastewater Treatment Works Upgrade

Hunter Water is upgrading the Boulder Bay Wastewater Treatment Works (WWTW) to cater for projected growth on the Tomaree Peninsula and anticipated increases in loads during peak holiday periods.

The upgrade will also improve the quality of biosolids leaving the site for reuse in agriculture.

The upgrade is happening in two stages:

  • Work for the Stage 2 upgrade will commence in June 2010 and take approximately 18 months to complete. The upgrade will provide additional capacity to cater for growth on the Tomaree Peninsula for at least the next four to five years and will ensure the plant can reliably meet the existing licence conditions.
  • The Stage 3 upgrade will provide the longer-term sustainable strategy for the plant, and will increase plant capacity to approximately 72,000 people to provide for growth on the Tomaree Peninsula to 2028. Further investigations and consultation with the community and key stakeholders are required before a decision on this strategy can be made.
