Apollo Bay, Marengo and Skenes Creek are supplied with water from the Barham River in the southern Otways.
A pump station at the river transfers water to the nearby Apollo Bay basin. From here, it is pumped to the Marengo basin.
The water is transferred via a pipeline to the nearby treatment plant, where it is filtered and disinfected.
An upgrade to the towns’ water supply was completed in 2014 to support the summer tourist influx.
