Project overview
The proposed project is aimed at reducing wastewater overflows and improving stream and beach water quality within the Hobson Bay catchment.
This project aims to transport wet weather flows from Engineered Overflow Points (EOP) during rain events to a storage tunnel before being passed on to the downstream network once the peak flows have passed. It will improve the collection and conveyance of wastewater to minimise the occurrence of spills and uncontrolled overflows that occur within the Hobson Bay catchment. The new wastewater tunnel will connect to three branch sewers located in the area.
