A two-part tariff was chosen, which includes a fixed charge and a volumetric charge that is the sum of an entitlement charge (on the water abstraction rights) and a usage charge (on water actually abstracted). Unregulated rivers and groundwater are still far from cost recovery levels, but the 2006 determination of bulk prices for 2006-10 increased fees paid by irrigators, while allowing them to move to a two-part tariff if they are willing to be metered. As a result of the full cost recovery policy, charges have risen by inflation plus 15% per annum between 2001 and 2005 for regulated rivers and inflation plus 20% for unregulated rivers.
