WATER DIRECTORY 2014 76 AUSTRALIAN WATER INFORMATION AND STATISTICS Typical Residential Bill (based on average residential water supplied)($) Source: www.nwc.gov.au/publications/topic/nprs/urban-2011-2012/chapter-5-pricing The typical residential bills presented in this section are the sum of xed charges and water (and sewerage in some utilities) usage (volumetric) charges to a residential customer, using each utility's average annual volume of residential water supplied (Indicator W12). Prices, which are presented in real dollars, may be set by government or, in some jurisdictions, a regulator. The size of the customer base has some in uence on bills. In the past, the typical residential bill for larger utilities has been lower than for smaller utilities. However, in recent years bills have been rising faster for the larger utilities, so that the difference has almost disappeared. The typical residential bill is also in uenced by the mix of xed and usage charges and the level of water consumption. Therefore, when drawing comparisons between utilities it is important to note that a change in the average bill may be the result of both a change in average consumption and a change in the price of water. All utilities now have some form of two-part (that is, xed and water usage) charge, while four utilities (the three Melbourne retailers and Byron Shire Council) have a volumetric component in sewerage charges. The typical residential bill increased for 55 utilities and decreased for three utilities in 2011--12 (Table 5.1). The national median increased from $971 to $1068 per residential property per year, a 10% increase. Over the Urban NPR time-series, the national median (shown in Figure 5.1 by the white lines that split the blue boxes) increased every year except 2007--08. Table 5.1.
