The Port Melbourne Drainage Pump Station on Esplanade West was built in 1891 to provide flood protection to a catchment of 126 hectares across the Port Melbourne area. The station houses four pumps that pump storm water from the historical wetlands out into Port Phillip Bay.
Three of the pumps were installed in 1951, with the fourth installed in 1981. All four pumps are nearing the end of their service life and require upgrading to ensure flood mitigation services are continued to be provided in Port Melbourne.
As part of the works, a cross-connecting drainage point located within Lagoon Reserve, off Graham Street, will be upgraded to prevent sea water from re-entering and corroding drain and pump station assets in the future.
