Wastewater Treatment

Utilisation of treated wastewater provides the following tangible benefits:

• reduction of effluent being disposed to local waterways;
• reduction in nutrients entering waterways, which may cause nutrition overload, which can lead to excessive algal growth within natural ecosystems; and
• reduction in potable water consumption.

Over the past twelve months South East Water in conjunction with the Alliance has continued to develop and implement wastewater re-use opportunities for customers . Significantly, this has involved completion of a wastewater re-use pipeline which will convey 100% of treated wastewater from the Blind Bight Sewage Treatment Plant to an existing turf farm at Five Ways, some 8 kilometres away. A long-term agreement will see water from the plant stored over the winter months for use over the summer period.


While the majority of re-use activities have been centred on the environmentally sensitive Western Port area, the Company is aware of the potential for growth in re-use opportunities on the Mornington Peninsula. The company therefore currently supplies recycled water to several vineyards in the area, which range from small boutique wineries (10 hectares) to larger, more established estates (200 hectares+)
