 The regulatory services in Portugal are done by an authority which is responsible for economic regulation, quality of service regulation and drinking water quality. Because we see drinking water quality as a part of the quality of service so we include that in the quality of service assessment. So we monitor the tariffs that are being applied by the operators to the either to other operators because there is a bulk sector and there is a retail sector so we regulate those tariffs. Also we monitor the tariffs that are being applied to consumers so we compare with each other we make sure that they follow a given structure and that this structure is transparent to consumers and not only the structure is good but also the costs are efficient. In terms of the quality of service what we do is to we have a set of data that we collect from operators we analyze this data and try to make it more sound so we do audits to all of the operators and then we produce a set of indicators that are more transparent not only to the sector but also to consumers in order for them to know what is the quality of service that is being provided to them. Also what we are trying to do is we try to establish some indicators that are more appealing to consumers and that are more understandable by them in order for them to to better know what is the service that is being provided.
