About the area

The Goldfields Superpipe is a 'common distribution system', meaning it services multiple other distribution systems. This pipeline is jointly operated by Coliban Water and Central Highlands Water. This pipeline transfers water from the Waranga Western Channel and from Lake Eppalock (Campaspe system) for use in the Coliban Water supply system and to supply water to Central Highlands Water’s Ballarat system.

For the purposes of this account, the Goldfields Superpipe includes both the pipeline from the Waranga West Channel to Lake Eppalock (known as the Goldfields Superpipe) as well as the pipeline from Lake Eppalock to Bendigo (known as the Eppalock – Bendigo Pipeline).

This system is supplied by Coliban Water.
