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

Reference connectionDomestic metered service — no connection-size parameter — the residential tariff carries no connection-size parameter. PUB's Annex A prices domestic water purely per cubic metre, and SP's published bill enumerates what PUB collects on a domestic account as water charges, NEWater charges, water conservation tax and waterborne tax. No standing or meter-size charge appears in either. The residential tariff has no size parameter to designate.
