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

Cost by volume

A household on 5,000 litres a month pays about 19% more per litre than one on 25,000, because the fixed charges spread over less water.

Where the water comes from

GroundwaterSurface

Paris draws roughly half its drinking water from springs up to 150 km away, carried by the Vanne, Loing, Voulzie and Avre aqueducts, and roughly half from the Seine and the Marne. No production figure with a year attached has been captured, so the shares are named and not quantified.

ScopeReference connection is a 15 mm individual meter, the smallest priced. Fourteen diameters are priced and none is designated.

ScopeCollective metering is the common arrangement in Paris and is not modelled. A household behind a shared meter does not hold its own abonnement.

ScopeThe separate non-potable network, priced at 0,5549 EUR TTC/m3, serves street washing and park irrigation and is not a household supply.
