 In 2006 investments were financed by municipalities (58%), (18%), private water companies (13%) and subsidies from the "Départements" and regions (11%).The contribution by municipalities is fully financed from tariff revenues collected for water and sanitation services, as well as by substantial fees ("part collectivité") paid by private operators to the municipalities (Euro 2bn in 2006, or 30% of the amount billed by private operators) for the costs of investments (service budget of the municipality).Only in the case of municipalities with less than 3,000 inhabitants some limited tax revenue (general budget) is used to finance water and sanitation investments.
