Stage Three

Stage Three:  Duplication of the East Point rising main

Treated effluent from the Ludmilla Wastewater Treatment Plant is currently discharged via the East Point outfall.  

In order to effectively cope with additional flows once wastewater is diverted from the Ludmilla outfall and the Darwin CBD, Power and Water will build another rising main to discharge via the East Point outfall.

Power and Water is currently preparing Public Environment Reports (PERs) for the duplication of the East Point rising main (stage three) and the extension of the East Point outfall (stage four).

The PER will assess and determine how best to manage any environmental impacts associated with duplicating the rising main to East Point and extending the East Point outfall.

The timing of construction for these works will depend on the outcome of the PER.
