Wannon Water operates under seven surface water bulk entitlements, each containing provisions on minimum passing flows and maximum daily extractions from waterways.

Wannon Water has a diverse range of water source supplies in its region, the three largest being the Otways system (Arkins Creek Catchment and Gellibrand River), the Grampians system and the Dilwyn Aquifer. The Otways and Grampians systems have water storages and transportation pipelines, whereas the Dilwyn Aquifer supplies directly to local treatment plants.

Additional surface water is collected in Wannon Water owned reservoirs and via supply from Grampians Wimmera Mallee Water's Rocklands Reservoir and Willaura Pipeline. The remainder of the water is supplied from groundwater bores, 21 bores are located throughout the region.
