for water and sanitation, further promoting the modernization of the sector and the consolidation of service provision. In the same year the regulatory agency IRAR began its work. Solid waste management was included in the purview of both AdP and IRAR, which was later renamed into ERSAR. Sector policies continued to be stable after subsequent changes of government in the elections of 2002 won by the Social Democrats and of 2005 won by the Socialists. A judgment by the European Court of Justice (ECJ) of 29 September 2005 found against Portugal for not complying with a series of drinking water parameters laid down in the EU drinking water directive. In 2007 the government published its second strategic plan for water and sanitation. Developments since 2007 In March 2007 the European Commission launched infringement procedures against Portugal for not complying with three Court judgements on the quality of drinking water. It also referred Portugal to the European Court of Justice over its failure to implement the EU wastewater framework directive. Environment Commissioner Stavros Dimas said: "It is important that Portugal comply with these Court judgements, since they have a direct bearing on public health and the conservation of important natural areas. The Commission has no choice but to continue with legal action if we are to achieve the level of environmental protection intended in our legislation." In 29 of the urban areas concerned by the directive, required collection and/or treatment systems are still not in place. For instance in Lisbon, the waste water treatment plant of Alcântara is not operational. In Matosinhos in the region of Oporto, only primary (basic) treatment is in place. In Costa de Aveiro, 60% of the polluting load generated is not collected and 65% is not treated. In Povoa de Varzim /Vila do Conde, 60% of the load was not collected and the level of treatment in place was unknown. In August 2010 a tertiary treatment plant started operating.(source missing) Concerning drinking water, Portugal still does not comply with some of the parameters of the EU directive. For example, almost 50% of water supply zones do not comply as regards total coliforms, while 20% of the zones do not comply with the faecal coliforms parameter. The situation improved in 2004, the most recent year for which Portugal provided data. Tariffs and cost recovery For regional companies water tariffs vary between 0.31 and 0.55 euro per cubic
