Water supply and sanitation in Belgium is provided by a large variety of organizations: Most of the 581 municipalities of Belgium have delegated the responsibility for water supply and sanitation to regional or inter-municipal utilities. There are more than 62 water supply utilities, including 2 regional, 30 inter-municipal and 30 municipal utilities. Another 100 mostly small municipalities provide services directly without having a legally of financially separate entity for water supply. Water is not scarce in Belgium and water supply is generally continuous and of good quality. However, wastewater treatment has long lagged behind and Brussels only achieved full treatment of its wastewater in 2007. In 2004 the European Court of Justice ruled condemning Belgium's failure to comply with the EU wastewater directive, and the ruling has not been fully complied with so far. Wallonia satisfies 55% of the national needs in drinking water while it counts only 37% of the population. Flanders and Brussels are dependent on drinking water from Wallonia, at a level of 40% and 98% respectively. An interesting aspect of the Belgian water and sanitation sector is the recognition of a basic right to water. The Walloon and Brussels Regions have set up Social Funds for Water, which provide financial support to people having difficulties to pay their water bill, while in Flanders everyone has the right to a minimal supply of 15 m3 (41 liter/capita/day) of free water per person per year. The average water tariff in Belgium for large users in 2008 was Euro 8.92 per cubic meter, the second-highest among 14 industrial countries compared in a recent survey. Between 2003 and 2008 water tariffs in Belgium had increased by 80%, the highest increase in that period among all 14 countries. Water resources Belgium's water resources are distributed among five river basins, the two main ones being the Meuse and the Scheldt that both take their source in France and flow into the sea in the Netherlands. The major aquifers are located in Wallonia. Belgium does not face water stress, despite its high density of population. Internal water availability is around 12,000 million m3/year (average 1990–2004), or 1,168 m3/capita/year. The yield of groundwater is around 900 million m3, exploited at a rate of 75%. This picture hides strong regional disparities, with the North dependent from the South. Wallonia satisfies 55% of the national needs in drinking water while it counts only 37% of the
