Impact de la tarification sur les stratégies de consommation et d'approvisionnement en eau des ménages
Analysing the impact of drinking water pricing on household water supply and consumption strategies
In France, the sharp increase of drinking water price observed during the 90's has lead a number of households to use raw water as a substitute for drinking water to satisfy part of their water need. Raw water sources include individual tube-wells, rainwater recovery systems or collective agricultural water delivery systems. This paper presents the consequences of such behaviour on the management of water utilities. A simple economic model representing households behaviour is proposed and used to highlight that water pricing can be used to regulate raw water use. The model is then applied to a southern France municipality.
