Both comparisons are proportions, so they hold across currencies. The bills themselves do not, and are not compared.
Cost by volume
No fixed charge to spread, so the price per litre is the same at any volume.
Where the water comes from
reservoirimported_raw_waterDesalination
Hong Kong draws on local catchment, raw water imported from Guangdong under the Dongjiang agreement, and the Tseung Kwan O desalination plant. Shares are withheld under Rule 9.5: no annual production mix with a year attached has been captured.

Reference connectionDomestic metered service — no connection-size parameter — the residential tariff carries no connection-size parameter. WSD prices domestic fresh water purely by volume across four tiers and enumerates the whole of what a domestic bill can carry. No standing charge, meter rent or size band appears anywhere in the domestic tariff, so there is no connection size to designate.

ScopeReference account is a separately metered domestic dwelling. A meter is installed at the supply pipe of each flat, so the household is the billing unit for fresh water.
ScopeThe benchmark runs at the statutory period of exactly 121.64 days. A real bill covers whatever interval the meter reader produced, and the tiers prorate to it — which is why the same consumption gives a different bill over 127 days than over 117.
