Blind Bight Sewage Treatment Plant Upgrade

South East Water’s Blind Bight Sewage Treatment Plant was upgraded from earthen lagoons to a mechanical IDEA treatment plant necessary to cater for the population growth in the Blind Bight, Tooradin and Warneet townships.

South East Water required assistance with the following:

• Design and documentation of the 1 ML/d (approx. $5m CAPEX) works;
• Tender phase assessment;
• Construction management and supervision; and,
• Commissioning assistance.

The works included:

• new IDEA process tanks;
• aeration systems;
• aerobic digestion;
• chemical dosing systems;
• sludge drying pans;
• building works and earthworks;
• 4ML HDPE lined effluent storage;
• 8 km Class C recycled water transfer pipeline; and,
• ventilation/odour systems.

The innovative design and construction management approach provided the following benefits to the community:

• The project team delivered this contract within the agreed programme and budget; and,
• The plant provides superior quality effluent for reuse opportunities.
