But authorites have warned Gellibrand, a small town about 175km southwest of Melbourne, the water is only fit for essential non-drinking purposes. Water authorities have been carting in water to "top up" the tank after being granted access to the site on Wednesday. "This water is to connect households and businesses to supply for essential (non-drinking) needs such as flushing toilets and showering," Barwon Water said on Thursday morning. "We ask that the community only use this water for essential non-drinking purposes and bear in mind that the supply will be contingent on carting (for now)." Once fire authorities deem it safe for the community to return, Barwon Water plans to set up a temporary supply of drinking water.
