Both comparisons are proportions, so they hold across currencies. The bills themselves do not, and are not compared.

Cost by volume

Volumetric rate 3.41 510152025 m³ per month

A household on 5,000 litres a month pays about 38% more per litre than one on 25,000, because the fixed charges spread over less water.

Where the water comes from

SurfaceDesalinationGroundwater

Greater Sydney draws chiefly on catchment storages managed by WaterNSW, with the Kurnell desalination plant and some groundwater. Shares withheld under Rule 9.5: no annual production mix with a year attached has been captured.

Reference connectionStandard metered residential service — the residential tariff carries no connection-size parameter. Sydney Water publishes one metered residential water service charge, A$26.65 a quarter, without differentiating by meter size; the unmetered charge is a separate and higher figure for a different customer.

ScopeReference account is a separately metered residential property. An unmetered property pays A
81.56 a quarter instead and is a different reference customer.
ScopeThe wastewater service charge is a fixed amount that Sydney Water states already contains a deemed amount for usage. Sydney's total water services figure therefore does not vary with the volume of water used, which is unusual in this Index and is the reason it is comparable at all — unlike Perth, where sewerage rests on a property valuation.
ScopeThe published rate is the non-drought rate. The drought rate applies while Greater Sydney storage sits below the 60/70 trigger, and the state has not been captured.
